Reducing Total Phosphorus In Water Resource Recovery Facilities

Source: YSI, a Xylem brand

One of the compounds that is critical for treatment plants to measure at many stages during the process — from primary settling to aeration and to effluent — is orthophosphates (also known as soluble reactive phosphorus and commonly referred to as phosphate). Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.
