Chemical mixing - sludge

Mixing chemicals into wastewater sludge

Sometimes it is necessary to mix chemicals into the activated sludge before it enters the secondary sedimentation tank. For example, chemicals may be used to perform phosphorous removal on the effluent from the biological process. Many plants use chemicals to improve sludge thickening just prior to the sludge buffer tank. The Sulzer agitator type Scaba is the best means of preparing polyelectrolytes or lime for this process, with positive displacement, progressing cavity dosing pumps used to transfer the polymers for sludge process handling.

Products

  • PC dosing pump
    In sludge dewatering and thickening, barrier layer injection and conditioning agents are added to the delivery pipework for lubrication, to reduce friction losses and system operating pressure.

  • PC transfer perform pump
    Designed for easy dismantle and reassembly, maintain in place without the need to disconnect, remove suction or discharge pipework and minimize time and cost.

  • PC transfer pump
    Sulzer’s competitively priced transfer pump, with close coupled drive and gearbox. This product has a small footprint, useful where space to install is tight and is available in low to high flow configurations.

  • Scaba side mounted agitator
    Scaba side-mounted horizontal agitators are ideal for mixing and agitating process liquids in demanding industrial applications.

  • Scaba top mounted agitator
    Scaba top-mounted vertical agitators are used for mixing and agitating process liquids in many industries, including wastewater and industrial applications.
