# NITREXTM NITROGEN REMOVAL WASTEWATER TREATMENT SYSTEM

Technology Description: Based on ten years ofresearch, a proprietarypatented nitrate-reactive media has been discovered that converts nitrateto inertnitrogen gas (denitrification). The NITREXlM reactive media is contained ina prefabricated tank or, forlarger installations, inan engineered excavation. Nitratecontaminated wastewater is gravitationallyfed through the treatment module. For septic tank applications, an oxidativepre-treatment step is required to convert ammonium (NH/) to nitrate (N03-)before the NITREXlM filtercan performthe reductive denitrificationstep. Pre-treatment can be achieved withany ofthe existing oxidative technologies commonlyused inwastewater treatment. The nitrate-free effluentfromthe NITREXlM filteris simplydischarged to a conventional tilebed or receivingwater body. Compared to other technologies, the NITREXlM filteris passive and essentially maintenance free. Itprovides almost 100% nitrate removalina lowcost easy to installprocess Application: The NITREX1M filtercan be used to remove nitrogen in water orwastewater such as treatment plants wastewater, septic tank effluent,agriculturalrunoff,and landfill leachate. For large flows,the NITREX1M reactive media may be placed ina linedexcavation, and the wastewater allowedto gravitationallypercolate through the reactive media. $ond Fiber Nilft!~ Filter TiI~Bed
