Can you spot the mountain goats?

Here is a photo of a system that has been in operation for 3.5 years. These MetaRocks have a single slit to increase surface area. Currently, we put three slits on each one. Again, no flushing, hosing, fluffing, replacing or washing has been done. MetaRocks are highly resistant to biological fouling and the most recent sample from this system measured about 6 mg/l total nitrogen. You can imagine how easy Eliminite maintenance is compared to other systems.

Here is an interesting photo. This system was installed four years ago an is located at about 7500 ft above sea level. You are looking at an older style version of our MetaRocks, we have improved them significantly since this system was built. What is important however, is that these MetaRocks have never been washed, hosed off, fluffed, changed removed, replaced or cleaned. There is obvious junk on them from opening the lid and knocking rocks and wood chips in the tank but the large open pores are also clearly visible. Here is the good part: the influent to this system is quite potent TKN: 112-164 mg/l and BOD 800-1500 mg/l.
When the Eliminite was turned on effluent TN measured 20.5 mg/l. Considering the minimal maintenance this system requires and its alpine location, a nitrogen reduction such as this is remarkable.

This is a picture of an Eliminite retrofit where we added a Model 120 C to an existing system in a locally supplied precast tank. We built the system in the field by modifying the tank to accommodate the Eliminite components. You can see our Lung in the foreground and the media bed in the large compartment. This system contains about 100 ft^3 of MetaRocks media.

We complete the job by continuing to fill the tank with MetaRocks media. This system has approximately 600 cubic ft of MetaRocks media and will treat 4000 GPD to tertiary standards. No smoke and mirrors here. We use a lot of our proprietary media and build a remarkably robust system with a small footprint and simple maintenance requirements.
