6 Steps to Reduce Total Phosphorus in Water Resource Recovery Facilities

Water Resource Recovery Facilities (WRRF) undergo continuous monitoring of multiple parameters and compounds throughout the treatment process on a daily basis. And the monitoring and subsequent control of those parameters and compounds during the process is essential to optimizing efficiencies of the plant on a daily, weekly, and annual basis.YSI-Tech-Note-622-Reducing-Phosphorus-in-WRRF-Cover.jpg

One of the compounds that is critical for treatment plants to measure at many stages during the process – from primary settling to the aeration tanks and to the effluent – is orthophosphates (also known as soluble reactive phosphorus and commonly referred to as phosphate).

Since phosphorus is the nutrient in short supply in most fresh waters, even a modest increase in phosphorus can, under the right conditions set off a chain of undesirable events in a stream, including accelerated plant growth, algae blooms, low dissolved oxygen, and the death of certain fish, invertebrates, and other aquatic animals.

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.
