Solids Contact Clarifiers

RockWater's solid contact clarifiers are designed and proven for highly efficient flocculation, sedimentation, and clarification in a single compact basin. Solids contact units are widely used for the removal of turbidity for lime softening, and for chemical coagulation in municipal and industrial applications.

The turbine mixer recirculates through the recirculation drum, achieving superior solids and complete chemical reaction. The formulation of floc particles occurs in the large, slow mixing reaction well.   The sludge discharge system maintains an optimal solids volume along the clarifier bottom for efficient solids contact within the mixing zone.

The mixture follows a path to the outlet under the edge of the well, which is followed by circumferential, vertical rise clarification.  This will make it free of any short circuiting, making possible for clear overflow and dense underflow in an easily controlled, hydraulically and chemically stable clean system.  The flow passes upward, the decreasing upflow velocities of the floc particles cause dynamic separation of the solids from the treated water.   Radial launders provide uniform effluent discharge while maintaining the upflow pattern.  The radial launders are available with v-notches or submerged orifices.

Solid Contact Clarifier

RockWater Superior Equipment

Everyone is aware of the superior clarifiers and thickeners being installed all over the country from RockWater, however our line of solid contact units are also in demand as our customers can expect the same heavy duty and new technology that they get from our clarifiers now from our solids contact clarifiers.  Our engineers have been designing these type of clarifiers for many years and have implemented new technology into these solid contact clarifiers which makes them solid and unique.
