Wastewater and treatment technology permits the removal of physical, biological and chemical impurities from water. The various cleaning procedures are performed in several cleaning stages. Microcontaminants are removed from the wastewater using special procedures, such as the application of ozone and carbon filters, for example. Sturdy eccentric screw pumps are generally used to do this.
Flocculating agents are used to remove the smallest particles of contaminants from the wastewater. The flocculating agents drive the cleaning process by means of an electrochemical reaction. Acids and lyes are also added to the wastewater for pH adjustment. Drainage of the sewage sludge is improved using polyelectrolytes, milk of lime and metallic salts. To accomplish this, pumps in stainless steel design with high dosing accuracy are used.
To remove sludge accumulation from water, we offer sturdy, flow-optimised pumps that provide the operators of sewage treatment plants with a high degree of efficiency.
One task suction pumps perform during wastewater treatment is to take on concentrated sludge, which is led to the sludge dewatering system either directly or via the fermentation stage. Following secondary clarification, the purified water flows through the sewage treatment plant diverter into the receiving waters. Many treatment plants use an additional drainage pumping unit for this purpose.
