Nitrate Water Treatment

Effective nitrate water treatment using biological or ion exchange technologies.

Nitrates are pervasive in the environment, originating from both agricultural, industrial and waste treatment sources. The US Environmental Protection Agency (EPA) has set a Maximum Contaminant Level (MCL) for nitrates of 10 parts per million (ppm) as nitrogen.

Envirogen has a wealth of experience removing nitrates from water using biological treatment with our fluidized Bed Reactor or with our proprietary ion exchange systems.

Nitrate issues

The majority of nitrate contamination in surface and groundwater originates from crop fertilization activities and discharges from animal operations, wastewater treatment facilities, and septic systems.  Additional sources include industrial discharge, residues from dynamite blasting at mining operations and deposits from atmospheric sources such as Nitrogen oxide emissions from power plants, cars, etc.

Envirogen Solutions for Nitrates in Water

Envirogen’s Fluidized Bed Reactor (FBR) system handles high flows at low cost with typical nitrate treatment efficiencies of greater than 99%. Our anoxic FBR systems have been successfully operated at flow ranges from 5 to 6,000 GPM.

Envirogen’s proprietary high efficiency ion exchange process produces recovery rates that are among the highest in the industry. Characterization of the raw water allows Envirogen engineers to design a system that will optimize the ion exchange removal and regeneration process, maximizing treated water delivered to your customers while minimizing salt consumption and waste brine generation.

Envirogen Experience

With over 26 successful applications removing nitrates from water, Envirogen has the experience to address your nitrate contamination issues.
