Reactor Clarifier™ Solids Contact Clarifiers

Flocculation and Clarification Combined in a Single Tank Reactor Clarifier solids contact units are designed and built to provide the most economical solution to precipitation and clarification requirements. The simple design provides for coagulation, flocculation, solids recirculation, clarification and positive sludge removal in a single basin. This eliminates the need for multiple tanks and additional pipe work. All units are backed by over 60 years of experience in engineering and manufacturing, ensuring the best fit for your unique plant requirements.

Principles of Operation:
Reactor Clarifier solids contact units combine slow turbine speeds and high volume internal recirculation to promote mixing, flocculation and solids-contact. The recirculation system is designed to promote particle growth and improve the removal of suspended solids. As influent enters the recirculation drum it is pumped upwards by a large diameter slow-speed turbine, where it comes into contact with a large volume of dense floc from previously precipitated solids (6 to 15 times the maximum influent rate is recirculated to increase solids contact with the new incoming feed). The resulting effluent is passed under the reaction cone to the clarification zone, with the heaviest particles settling to the floor. These are then raked to the center for recirculation or discharge.
