Extend Maintenance Intervals with Peristaltic Pump Technology

The Qdos peristaltic pump is delivering a significant reduction in maintenance time — from 1.5 hours to just five minutes — at the effluent plant in Selters (Westerwald), Germany. 

“Wastewater is purified and discharged into a nearby stream — the Saynbach,”  explains Achim Linder, plant manager. “An important stage in the purification process is the elimination of phosphates, most of which come from domestic washing and cleaning products.” 

The addition of the precipitant converts the phosphate solution into insoluble phosphate compounds, which can then be isolated. Depending on the phosphate content of the inflow water, delivery is between 60 and 250 mL of ferric chloride per minute. Until fairly recently, diaphragm metering pumps were used, but these proved insufficiently robust. 

“The ferric chloride attacked the pump diaphragm, meaning it had to be changed every three to four months,” explains wastewater manager, Bernd Schenkelberg. “This took one of our technicians at least an hour every time and, because of the subsequent leakage of ferric chloride, almost as long again to clean the metering station.”
