The upgrade of chemical dosing equipment at a wastewater treatment plant (WWTP) in Germany is delivering high performance sludge dewatering through more reliable polymer dosing.
Safe and reliable chemical dosing helps WWTP operators meet the required environmental standards at the facilities they manage every day of the year.
A facility in Heide, a small town in Schleswig-Holstein, Germany, has upgraded the polymer dosing pumps in its sludge conditioning process with specialist peristaltic pumps to reduce the maintenance interventions and polymer leaks it experienced previously with screw pumps.
In Germany, strict regulations for harmful chemicals, pharmaceutical residues, and microplastics mean the opportunities for reusing wastewater sludge as agricultural fertiliser are increasingly limited and sending it to a landfill is usually not permitted.
This means thermal recycling is becoming more accepted as an effective route to sludge disposal, but the required dewatering and polymer dosing during the sludge conditioning process can add significant costs.
Identifying cost-efficiencies in the dewatering process can mean significant savings for...
