A Valuable Process Control Test that is Quick, Easy, and Accurate

The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.
