Improving Compliance Through Real-Time Phosphorus Control

Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus large fines. The widespread practice of manually testing effluent only at set time intervals often leads to overdosing or underdosing with chemical control. Overdosing occurs when control the same rate even when phosphorus levels are low. Underdosing happens when phosphorus levels spike in the interval between tests. This sends excess phosphorus into the stream before control measures can be adjusted.

Real-time control offers continuous monitoring to allow accurate dosing, giving plants better control over operations, regulatory compliance and costs. This white paper will describe a system for real-time control and the benefits it offers, specifically for plants that are controlling phosphorus by chemical dosing with ferric chloride (FeCl3 ).
