PumpingFerric Sludge
WhereUK waste water treatment plant
Replaced Progressing cavity pump
WhyFerric sludge is abrasive causing stator wear & results in increasing pump speeds to maintain flow rate
Increasing speed increases suction pressure & reduced settled sludge content as more water was pulled into lines ("rat holes in the sludge blanket")
 
BenefitConsistent suction reduced water content for drier sludge & lower waste disposal costs
Reduced Maintenance Costs
