Nutrient Removal

Envirogen Technologies' suspended carrier reactor (SCR) process can help you achieve nitrogen control or improved nitrogen reduction. 

The addition of our SCR S1 or S2 plastic media to your existing activated sludge basin enables achievement of higher treatment capacity or an increase in treatment performance by maintaining a higher biomass concentration within the basin. This supplemental biomass growth occurs in the form of a biofilm on the surface and within the interior of the buoyant carrier media. 

This aids the nitrification process, as slow-growing nitrifying microorganisms can now be more easily maintained within the system as an attached biofilm. Screens are used to prevent the media from leaving the basin. A simple patented in-vessel device is used to control the biofilm thickness. The complete system retrofits entirely within the existing plant footprint.

Our SCR process can also expand your existing biological treatment plant capacity without the need for additional reactor volume. The process is simple in mechanical design, requiring little in the way of instrumentation, controls addition, and no more operator attention and maintenance requirements than the conventional activated sludge system that it upgrades. It is a very attractive alternative to the financial and timeframe impact of addtng new treatment trains to existing facilities or retrofitting with membranes.

Envirogen Technologies Advantages:

• Low purchase, installation and operating costs
• Can increase capacity by as much as 100%
• Net zero impact on existing plant operating labor requirements
• Insignificant impact on instrumentation and controls requirements
• Contained in existing plant footprint; net zero impact on real estate requirements
• Operational flexibility
• Consistent effluent quality; tolerance for upset and surge conditions
• Use of patented in-vessel devices to control biofilm thickness on and in the carrier media, allowing the use of fine bubble aeration, which reduces energy requirements
