First Sample 98% Nitrification, Second Sample 80% Reduction in TOTAL Nitrogen

I wrote about the highway rest area wastewater treatments systems we designed and built for the Montana Department of Transportation (MDT).  (MDT made a determination that it was in the best interest of the public that Eliminite be the sole source provider of wastewater treatment systems for all its facilities.  This "Public Interest Finding" was approved by the Federal Highway Administration.) 

This particular WWTS was started in the winter and, at this location, it gets cold and stays cold.  We collected a sample in January which showed that even in the extreme cold, the system was providing about 98% ammonia conversion to nitrate. 

We collected the second sample a week ago and found that the systems nitrogen removal was already at 80%.   I expect the Nitrogen levels to continue to fall.

This is excellent treatment considering the high nitrogen concentration of the incoming wastewater.  In fact, we are already operating better, with a cold weather startup, than most "advanced" systems receiving residential wastewater.  (take a look at the "Best Available Technology" data from an NSF 245 system I posted a few weeks ago.)

Here is some icing on the cake.....No alarms, no failures, no problems. We started the system and it has been operating perfectly.  No media to wash off...no cubes to fluff.

Yes.  This has really irritated the peddlers of competing systems.  You can imagine the incessant puling and crying.  They are even trying to have the PIF rescinded.  The fact is, we received the job through a fair bidding process.  Eliminite came in tens of thousands of dollars less and we were awarded BOTH jobs saving the taxpayers tons of money AND using local suppliers to the max.  But they have friends in high places...so the hell with the best interest of the taxpayers. 

I did have to point out some shenanigans with one vendor however.  The peddler sort of ignored the engineers design flow and submitted his proposal with a system that was 1/3 of what the  manufacturer would require.  I guess he figured that he would spring the news on the taxpayers later.   My guess is they would have blamed the upgraded system on the Department of Environmental Quality.   I pointed this little "oversight" out to the contractor and he asked the vendor for a system meeting the engineers design requirements.  You can guess what happened next,  the correctly designed system was much more expensive than the Eliminite system and Eliminite won the job.  Oh...but the whining....I would bet there isn't a single pair of dry big boy "Huggies" in their entire organization!  Wait until they find out that we just beat them on a school wastewater treatment system yesterday.

I am always happy to discuss how our little Montana company is able to provide system that out perform the others.  So give me a call...fire off an email.

Montana's highway rest areas are more picturesque than other states resorts!

They have better wastewater treatment systems also. 

Eliminite has been selected as provider of all wastewater treatment facilities for Montana Department of Transportation (MDT) highway rest areas and other facilities.  Through its process, in conjunction with the Federal Highway Administration, MDT determined that it is in the best interest of the public for Eliminite to provide wastewater treatment systems for all its facilities. The systems are compact, reliable and specifically designed to treat the high nitrogen wastewater (ammonia =180 - 250 mg/L) common to highway rest areas. 

***UPDATE***
(The prime engineers on this project refused to collect actual wastewater influent samples and instead, guessed at the BOD and TN values.  They are not good guessers, Actual BOD Influent averages about 1200 mg/L.  Actual TN Influent averages about 450 mg/L)
The foot print of the entire treatment system is about 20' x 40' and uses all locallly supplied precast concrete tanks.  That makes good sense for our local economy because area suppliers can provide equipment rather than shipping money out of state to import equipment from out of state, or country, suppliers. 

We can do this in any location using locally available tanks, and components because the design of the system is flexible and can be modified to accommodate almost any tank configuration.  This not only provides a boost to the local guys but also results in significantly lower overall cost.  As you all know, "pod" type systems must be shipped in from somewhere.

This system was started and sampled in the dead of winter and is already achieving about 98 % conversion of ammonia to nitrate.  No alarms, no malfunctions, no phone dialer.  The average mean temp was around 20 degrees F for the operational period.

Is NSF certification anything more than a "Pay to Play scheme"?

I am sure many of you have asked the same question.  How often do we hear of NSF certified systems that fail to meet even the most magnanimous state standards?  The game is interesting, states develop standards for say, nitrogen, which, I have to assume are based upon some need for a nitrogen standard.  They don't pull these things out of mid-air...do they?    Onsite systems are then supposedly required to comply with the standards.  This seems to be true unless the system has an NSF certification.  Once the system is approved by the state, the certification trumps any actual field data however consistently bad it is.  I was told by one regulator that once the system is in the state with NSF, it is nearly impossible to get them out due to the threat of lawsuits by the aggrieved manufacturer.  This means that while the system is "certified" on paper to meet the standard, the actual data show something different that the regulatory community can not or will not correct. 

NSF, from what I have heard uses municipal wastewater that has been through a primary sedimentation process.  This sounds like "normal' residential wastewater, don't you think? 

The lowest flow certification is for 500 gal/day.  Any person that knows anything about this field knows that homes NEVER produce this much wastewater unless something in the home is broken.  If your state standards say they do, your standards are wrong.  Seriously, we are talking about potty breaks, showers and laundry not Blue Fin Tuna farming. Oh....Do Americans really still have "laundry day"?  I suppose so but only if the laundry is done at the local laundromat.  Right?  Think about it.

Why would "laundry day" matter?  I suppose if the system happens to be a Failure -prone Aerated Septic Tank, the worry would be washout. (although, since those things don't work anyway they might as well be clean and meadow fresh)  If we are talking about the systems using filter fabric the concern is hydraulic overload and biological clogging of the fabric. 
So I take a look at this system, call it brand x, and review its sample data from a single family home producing around 150-200 gal/day and can see that it doesn't have a prayer of meeting the 245 standard of 50% removal it reportedly received while treating 500 gal/day in the NSF program.  What is the real story here?   

Just for fun I have pasted sample data from an NSF certified system (in red below) and sample data from a non-NSF certified Eliminite 120C (in green) collected during the same third party test. Remember this is ACTUAL data collected by a state funded third party.  The NSF system is listed, for instance,  as Best Available Technology (BAT) In Maryland.  Really, Best??

Follow-up to last post

In my last post I told you about a system we installed four (4) years ago that the maintenance provider failed to inspect.  The system is at a high elevation in an area frequently mentioned on the weather channel as having the daily low temperature in the continental United States.  It is clearly NOT the NSF test facility in Waco, Texas.  It has been in continuous use.

The samples came back today and the system that has received NO MAINTENANCE for 4 years was producing effluent with 9 mg/l total nitrogen.  That's Ammonia + Nitrate + Nitrite + Organic Nitrogen, Total Nitrogen = 9 mg/l.

Our MetaRocks media looked as perfect as the day it was installed.  I am fairly certain that there is not a system available that can make this claim. And, when you factor in the price, Eliminite represents the best value in onsite wastewater treatment. This is an indisputable fact.

The "Big Guys" have been spending a lot of time on this blog.  They must be pretty slow in the manufacturing plant or they must be trying to figure out what to copy from Eliminite next.   I hear through the grapevine that their maintenance providers are still pretty busy though.  How would you like to be a homeowner, fighting through this awful economic recession only to get yet another bill for service to your septic system. And, if you don't pay it, they void your warranty (here is a secret, you never really had one anyway, it was always YOUR fault) and then, in order that the insult be brought fully to fruition, they turn you into the State for not renewing your maintenance contract. 

Here are some total nitrogen numbers from a third party test being conducted on one of our systems in in New Mexico:
11.2  I made an adjustment here to get the number down.
6.75  It looks like it worked.
5.1
4.7
4.6
5.0
8.6
6.5
3.6
The background Total Nitrogen was around 60 mg/l. 

These were taken over about a 6 month period from one little ol' Eliminite that cost a ton less than than one of those silly fish tank filter systems and about the same as those ridiculous septic tank bubbler activated sludge contraptions.

Maintenance, O&M, and Service Requirements can tell you a lot about an onsite system.

Most of the onsite industry has it all wrong and is out of touch with the rest of society.   Think about it;  if you buy manufactured products, you know that manufacturers are trying to create products today that are more durable and reliable than yesterday's products.  Automobile manufacturers have improved the reliability of their vehicles to the point where many brands advertise 100,000 miles between tune ups.  Paint manufacturers have developed blends that claim 20 years between reapplications.  The mean time between failures for my new computer hard drive represents a 100 fold improvement over previous models.  Reliability has always been synonymous with quality; if something lasts a long time and does not require constant observation,  maintenance and service to remain functional, that is a clear indication of a high quality product. 

Certainly we have the option of buying cheaper, less reliable products that we know will not last, or will require intensive service to keep functional.  I am thinking Yugo here...remember them?  If you were a Yugo mechanic you could probably keep one running...for a little while, anyway. 

*As a quick aside, here are a couple of well-known Yugo jokes:  Do you know how you double the value of your Yugo?  Fill the gas tank.

What's the difference between a Yugo and a door-to-door salesman?  You can close the door on the salesman.

Obviously, when a product becomes the butt of jokes like this, it's time to throw away the mold and retool, or get out of the business.  Yugo chose the latter option.  Today, however, too few Yugo-esque onsite system manufacturers are throwing away their obsolete molds...instead of being innovative in their retooling efforts, they have become exceptionally innovative and ambitious in their lobbying, marketing and liability-reduction efforts.  It's cheaper to convince regulators that more rigorous maintenance programs are necessary than it is to develop a system that requires less maintenance. 

Many manufacturers of advanced onsite treatment systems prefer to move in a direction opposite of greater reliability, durability and reduced service toward a requirement for more maintenance visits, more media cleaning, more tank pumping.  One manufacturer has taken this idea to such extremes that the treatment system is required to be connected to a dedicated telephone line 24 hours a day, 7 days a week.  Some might interpret this intense degree of remote monitoring as a sign that the product teeters on the edge of catastrophe every second of every day.  I say this because the only reason I can think of why a manufacturer would impose such a procrustean requirement is because it is a necessary  component if the system is to function at all.   I can't think of too many household products with a requirement for 24/7 remote monitoring...not even the really dangerous ones that commonly catch fire are shepherded with such sophisticated software.

I have a furnace in my home.  It could explode and burn the house down and with that in mind it represents an imminent danger.  But my furnace is not connected to a phone line.  Why?  Because it is reliable and the fact that it has been functioning for years with no trouble is the clearest indication of its quality.

In fact, the only thing I can think of that is connected to mission control 24/7 is the space shuttle and International Space Station (Who said septic systems are not rocket science?).

Now let me be clear; community, clustered and some rural systems do benefit from this type of monitoring and I appreciate the benefits they provide. I utilize these devices as a convenience.  The system will function adequately without 24/7 monitoring.  But, for single family residential systems, a SCADA control system is excessive, and the only reason you would include one as a minimum requirement is if the system really needs it to let someone know it's broken ...again. 

I suppose another handy feature of constant monitoring is that the manufacturer will have volumes of data to point to in the event of a system malfunction...any homeowner who dares to suggest that the manufacturer should assume the expenses associated with a premature malfunction or failure will likely be greeted with pages of data demonstrating how the malfunction or failure was the fault of the homeowner, not the system.  Perhaps the homeowner used more water than the system was designed to handle on several occasions during the months preceding the failure, or perhaps there was a power outage at the home while the owners were away, so the system wasn't on all day every day...all of this data and more will be available to the manufacturer with the click of a mouse. 

The notion that the primary purpose of remote monitoring is to "tweak" the system remotely, thereby eliminating the need for an in-person service call, just doesn't seem to play out in the field.  In fact, I have spoken with a number of maintenance providers who say that they have had to respond--in person--to every single alarm on every system they maintain.  Remote "fixes" are few and far between.  With the majority of alarm states occurring during highly inconvenient times such as holiday weekends when families host guests in their homes and flows increase, I can only imagine that a fair number of maintenance providers have grown tired of the overzealous remote monitoring programs because they seem to serve but one essential purpose:  to more effectively communicate a wider array of alarm states to maintenance providers so that an inherently unreliable technology can be coddled back into compliance whenever the pesky homeowner has done something to "wake the baby", so to speak.  By "something" I mean the homeowner has, for example, flushed a few too many times in a given 24-hour period.

I was on a job the other day with an Eliminite system that was installed about 4 years ago.  The property had been sold and the new owner asked me to visit with him and explain the system.  Apparently, the previous maintenance provider did not visit the system so it had been operation the whole time with no inspections.  When I arrived, we opened the lids, checked the pumps and panel and inspected the MetaRocks treatment media.  Everything was functioning correctly and the media was in perfect condition. No clogging biomat, no ponding, no stink and no need to hose off the media...no need to "fluff" it, change it jostle it.  I explained the system operation to the owner and when I arrived back at the office I found this email he sent:  

I'm impressed that a new concept can operate for 4 years from start-up with no malfunctions or routine check-ups. I've been through a lot of start-ups but not many that had no problems.


In my opinion, the requirement for perpetual maintenance contracts covering onsite system has allowed manufacturers to peddle systems that are fundamentally unreliable because they have to be covered under a service contract any way.  So who really cares if it work well or not, a Yugo mechanic is buying it.  This has resulted in the dumbing down of the entire industry because there is no driving force for innovation or improvement.

Eliminite rejects that position and successfully designs, builds and installs more durable, reliable, efficient and less costly advanced wastewater treatment systems than any other manufacturer. 

Do you remember the "lonely" Maytag repairman TV commercials? He was lonely because Maytag products were so reliable that all he did was sit in his shop waiting for a repair call that never came.  I would bet the pod people wish for a little Maytag solitude.

It has been a long time since my last post because I just have not had the time to sit down and write something.  Actually, I have been writing a lot...design reports, site plans, new system designs, computer code etc.  My work load has necessitated that I put this aside for a while. 

We have been installing Eliminite systems in various configurations at an amazing pace and I appreciate the trust that has been placed in our products.  The pace has been so brisk that we have added two new distributors who have become very busy keeping up with the orders and installations.  I'll try to remember to get some photos up for you to look at.  

I know that some of my clients will see this new post and wonder why I am wasting time with this blog when I have system quotes to get out for them.  Don't worry, I'm getting caught up and you are next on my to-do list. 

If you are designing a system please please please, give us a call before you begin and discuss options.  I feel so bad for the guys that design with a competing system because they "design as I see fit" (actual quote from one of the particularly enlightened engineers) only to have their client find out about Eliminite and how much better we can serve them.  This situation leads to all kinds of ill feelings where we wind up redesigning the system (sometimes the whole development) and the developer vows never to use XXX and Associates ever again.  It is really pretty embarrassing for the engineer/designer so don't get hypnotized by their glossy marketing and slight of hand.  Eliminite makes sense and it is just plain better that peat pods, aerated septic tanks or textile filters.

Owners Prefer Eliminite
I spoke to an engineer a couple of days ago that told me his clients have NO CHOICE but to install a textile filter plastic pod system.  The engineer stated that the client MUST install a field of buried plastic boxes filled with fish tank fabric because they are required to do this by some obscure, unnamed entity.  In my opinion this sounds as if the engineer has some agreement with the supplier or manufacturer of the textile system because the client is surely not under any order to install the plastic pod system.  I spoke with the client on this job and he had no idea what the engineer was doing and had in fact been given an entirely different story than the engineer gave to me.

 At $700,000.00 for a 14,000 gpd textile pod septic system somebody has a pretty significant financial stake in this one.  The truth is I hear this line pretty often.  I think it is because most people want the best value for their money and when they compare Eliminite to every other system, we usually represent the highest value and they select one of our systems for their project.  Losing the sale causes the competing distributor to suffer from a sever case of heartburn and this is where the shennagins start.  They will tell the owner that they cannot even obtain a quote from Eliminite because, for instance, the State required the textile filters(absolutely untrue) or that we are working out of my garage(again untrue....my garage is so cluttered that I can barely walk through it let alone work out of it).  If you are an owner and start to hear statements like these, give me a call.  I will honestly discuss your job and your options with you. 

What really bothers me about the 14,000 gpd system above is that is it for a school and the students are trying to raise money for the septic system on Youtube.  So these kids are working hard trying to come up with creative ideas to build a septic system and the engineer will not even entertain the thought of a more reliable, less costly alternative.   The money they save could be used for silly things  like BOOKS, and TEACHERS.  This kind of crap is so common in this industry that it usually gets overlooked but it just makes me sick.  The engineers should b ashamed and demand that K-Mart refund their money for the licenses they purchased during a Blue Light Special.

Textile Company Decides Eliminite has the Best Design
In a previous posting I wrote about the well known septic textile company that is viewed by many as leader in the onsite industry copying one of our designs, effectively establishing Eliminite as the state of the art.  Our systems are designed deliberately to function reliably in a harsh environment.  Contrast this approach with the apparent acts of desperation of the textile company.  Maybe this explains why they have so many malfunctions, alarms, failures and discontent among their users.  Our goal is to provide reliable systems for a reasonable price.  I think, considering our growth, sales and now, imitation by big companies, we are accomplishing this goal.

Drowning with the Turkeys
Back in January 2007, Onsite Installer magazine published an article titled, "Soaring with the Eagles".  (I loved this one so much that I scanned it and saved it.  I was looking through an old USB thumb drive the other day and rediscovered it)  The article describes a treatment system in Minnesota that makes me laugh until I nearly cry every time I read it.  It reminds me of those Far Side cartoons that no matter how many times you read it it's still funny as hell.  This one is a classic.

It tells a tale of a 99 lot subdivision served by a peat pod system.  Now I don't know exactly who or what cast the spell over the designer that caused everyone of his/her synapses to fuse into a useless mass of mental slag,  but if I didn't know better I would think this is one of the best Onsite April Fools jokes of all time.

The system is comprised of 320....yes...you heard that correctly 320...plastic peat pods.  This one even beats the textile pod nightmare in Montana that used something like 45 individual plastic fish tank fabric filters. They rig these things together as if they were stringing popcorn to decorate a Christmas tree.  It is one of the dumbest things I have ever seen and is an embarrassment to this industry. I am working on a 109 lot development and the footprint for the system is about 30' x 30' and it is fully accessible all year. 

The peat system is clearly visible from outer space (you can see it on Google Earth) and if there are extraterrestrials watching our development it will surely postpone their planned visit to introduce themselves because from the looks of that system earthlings still have some evolving to do.  The development is listed for sale for about 4 million and not a single home has been built so I guess,on the bright side, 3 years later,  the pods haven't clogged.   I pity the person that buys this monstrosity.  Soaring with the eagles...come on.
