ITT Leopold upgrades elimi-NITE system

ITT Leopold's elimi-NITE 2.0 system better defines the operational characteristics of different types of silica media and better defines the different ways to operate and control the filter. One of the control schemes uses feedback control of the carbon source used in the filter. The precise chemical control can reduce chemical usage and also produce a precise effluent nitrate concentration.

Features of the elimi-NITE 2.0 denittrification system include several types of liquid level control, optimum media selection, and backwash and run time optimization. The system can also be used to remove phosphorous.
