Nutrient Removal

Nutrient removal is achieved by reducing the levels of nitrogen and phosphorus levels with advanced wastewater technologies. Higher quality wastewater effluent is the result of this process.

Nutrient Removal

With so many efforts today in trying to make a sustainable environment, there are more stringent discharge limits than ever before that communities have to meet. Enhanced nutrient removal (ENR) provides the highest quality effluent possible by lowering nitrogen and phosphorus levels.

In order to make sure that your municipality produces the highest quality effluent possible with ENR solutions, it is important to know the steps that you will need to take with your wastewater technology.

ENR Solutions provided by Evoqua Water Technologies include the following steps:

  • Simple effluent polishing with filtration that requires little change to your existing equipment
  • Advanced biological treatment
  • Retrofit existing technology with newer and more advanced methods that maximize your investment

We offer the SENRgy Solutions Strategy for Enhanced Nutrient Removal. This solution uses advanced biological and filtration processes in combination with a customized plan to fit your specific ENR requirements.

Nutrient Removal Technologies for Your Wastewater Applications:
Biological Treatment
Gravity Filter Systems
Chemical Feed Controllers

If your equipment is in good condition and doesn’t need replacing but needs updating to meet ENR requirements, then our Retrofit and Refurbishing Services for Wastewater Treatment Equipment may be the solution for you.

Nutrient Removal Case Study

Enhanced Nutrient Removal Achieved with OMNIFLO® SBR

The City of Fruitland, Maryland needed to expand the capacity of their wastewater treatment plant from 0.5 to 1.0 million gallons per day (MGD) while upgrading its level of treatment to include enhanced nutrient removal (ENR).  The facility also needed to upgrade their facility to meet the requirements of the Chesapeake Bay Watershed project.
