Hach Company is taking the guesswork out of the chemical phosphorus removal process. Its new RTC101 Phosphorus Control System provides real-time control of chemical dosing that helps maintain consistent phosphorus levels in effluent waters. While some facilities adjust their chemical dose based on flow or by setting a fixed dose rate, being able to quickly adjust for loading changes can significantly lower chemical costs. With inconsistent phosphorus levels in the effluent, the volume of sludge produced can also increase.
