Versatile and simple to operate, the Ecoprocess MBBR wastewater treatment system from Premier Tech Aqua is designed for a wide variety of commercial, institutional applications and municipal projects with a flow rate up to 55,000 gpd. The system is suitable for the effluent discharge criteria that must meet at least 20/20 levels in BOD5 and TSS, and require nitrogen removal. It is available in concrete, steel or robust large-capacity rotomolded polyethylene tanks that can be assembled in single reservoirs up to 12,000 gallons, offering ease of installation and flexibility. The system can be used for retrofit designs or integrated in multi-phase projects. An Ecoprocess Coco Filter Polishing Unit, a compact, virtually no-maintenance biofiltration process using a 100-percent organic filtering media that treats wastewater with no energy, can be installed downstream when a more stringent discharge criteria of below 10/10 must be achieved. 604/346-8199; www.premiertechaqua.com.
