Coagulants work by adding a specific charge to a system of water. As 95% of contaminants carry a negative charge, the addition of a positively charged coagulant neutralizes the overall charge allowing particles to agglomerate or flocculate together to settle out of solution. With a wide variety of coagulants available in the marketplace, we believe there is value in distinguishing what variables are effected by the use of each type of widely used coagulant. The second half of the course outlines the Global Harmonization System Transition.

Basic thru Intermediate

With the use of Aluminum, Ferric, and Polymers as a primary coagulant results will vary. Jar testing is used to match up system characteristics in a small scale. With system water characteristics like pH, Alkalinity, desired removal rates, etc. we can weigh the positives and negatives associated with each coagulant. Sludge production, Alkalinity consumption, cost per pound of coagulant, and discharge permit levels dictate which chemical is the best overall fit for your system. We outline the content of the MSDS to SDS transition as well as the entirety of the planned changes with the Global Harmonization System Transition.
