Used Model SPC22 Krofta Supracell Clarifier, T316L Stainless Steel Construction
This system is an advanced clarification system using combined settings and floatation techniques and can be used in a variety of ways including fiber recovery. Approximately 2 min 30 second retention time.
Designed for approximately 1160 GPM (264 cubic meter per hour).
22′ diameter x 25 ½” deep tank. With rotating spiral scoop, size 1000 Air Dissolving Tube rated for 260 GPM
Includes Pump. New in 1991.
The inlet, outlet, and sludge removal mechanisms are contained in a the central rotating section of this clarifier. Un-clarified water is passed through the Air Dissolving Tube and released through a rotary joint in the center of the tank, than passes through the distribution duct, which is moving forward at the same velocity as the incoming water. This creates “zero velocity”, which allows for the settling and flotation process. The scoop than skims the floated sludge and discharges it into the stationary center section, where it is subsequently discharged by gravity.
