The patented Equaris BMRC and Greywater Treatment Systems combine the logic of waste separation and Mother Nature’s principals of composting and extended aeration to safely, efficiently and economically reduce water consumption and environmental pollution.
The Equaris Technology Helps:
Greywater is plumbed to a series of separate wastewater treatment and filtration tanks. This System consists of a Surge Tank for flow control, an Aeration Tank to produce aerobic conditions and a Clarification Tank to return the settled solids back to the Surge Tank. An extremely energy efficient air compressor provides an abundant amount of air to continuously circulate the wastewater.
Utilizing the standard wastewater treatment technology of extended aeration, the water is aerated and bacteria grow on the interior surface walls of the tanks. As the water is circulated by the 67 watt, 110 volt linear air compressor the bacteria clean the water in a natural process. By separating the toilet flow from the greywater, the estimate for water consumption and greywater treatment is 40 gallons of wastewater per person per day. Based upon 24-hour retention for adequate treatment of the greywater, the estimated treatment capacity of each Greywater Treatment System is 250 gallons per day. For flows over 250 gallons per day additional Greywater Systems are added and installed in parallel. The aeration and circulation process biologically filters the wastewater, producing a treated wastewater effluent quality that can then be efficiently and economically filtered and disinfected for reuse. The quality of the treated water was independently tested by Olmsted County, MN and documented the following reductions. TSS 50—88%, Kjeldahl Nitrogen 83-90%, BOD 78-93% and Fecal Coliform 1000 fold.
Each of the three rotationally molded polyethylene cylindrical tanks are 26” in diameter and 51” high. Each tank has a 60 degree cone welded into the bottom of the tank and all of the plumbing pipes for aeration and sludge removal are installed at the factory. For ease of maintenance, a sludge removal system pumps solids from the bottom of each tank to the BMRC for final treatment.
Installation takes two persons about three hours and consists of connecting the tanks together with the 2” Fernco connectors, adding water and adjusting the aeration manifold.
