After ozonation, the water enters the rapid mix basins where a coagulant is added to facilitate the removal of suspended particulate matter. The rapid mix basins provide quick and uniform dispersion of the coagulant. Coagulants react with particulates in the raw water to enhance their ability to bind together.
Following the rapid mix basins, the water is gently stirred in a three-stage flocculation process. As the water slowly travels through the flocculation basins, the particulate matter continually collides and sticks together into progressively larger particles called floc. The multi-staged basins along with variable speed mixers allow for optimized treatment as water quality, flow rate and temperature vary.
