NS / IS clarifier

High-rate capacity in less than half the space of conventional sedimentation

The NS / IS Clarifier employs the principle of internal slurry recirculation to accelerate chemical reactions and dense particle growth. Mixing and reaction, return flow, and sludge removal functions are performed in a single-basin unit that requires less than half the volume of conventional multi-tank systems.

Overview

NS / IS Clarifier Overview

The NS / IS Clarifier employs the principle of internal slurry recirculation to accelerate chemical reactions and dense particle growth. Mixing and reaction, return flow, and sludge removal functions are performed in a single-basin unit that requires less than half the volume of conventional multi-tank systems.

The key to principle operation is Accelator’s low-shear rotorimpeller combination, which controls mixing and slurry recirculation at independent rates to handle rapid changes in water characteristics. The NS / IS clarifier employs dynamic separation of slurry from clarified water allowing increased loading rates versus competing technologies
