NITREXTM

NITROGEN REMOVAL WASTEWATER TREATMENT SYSTEM

Technology Description: Based on ten years of research, a

proprietary patented nitrate-reactive media has been discovered

that converts nitrate to inert nitrogen gas (denitrification).The

NITREXlMreactive media is contained in a prefabricated tank or, for larger installations, in an

engineered excavation. Nitrate contaminated wastewater is gravitationallyfed through the

treatment module. For septic tank applications, an oxidative pre-treatment step is required to

convert ammonium (NH/) to nitrate (N03-)before the NITREXlMfiltercan perform the reductive

denitrificationstep. Pre-treatment can be achieved with any of the existing oxidative

technologies commonly used inwastewater treatment. The nitrate-free effluentfrom the

NITREXlMfilteris simply discharged to a conventional tile bed or receiving water body.

Compared to other technologies, the NITREXlMfilteris passive and essentially maintenance

free. It provides almost 100% nitrate removal in a lowcost easy to install process

Application:

The NITREX1Mfiltercan be used to remove nitrogen in

water or wastewater such as treatment plants

wastewater, septic tank effluent,agriculturalrunoff,and

landfillleachate. For large flows,the NITREX1Mreactive

media may be placed in a lined excavation, and the

wastewater allowed to gravitationallypercolate through the reactive media.
