Progressive Cavity Pumps for Power Plant Wastewater & Sludge
Controlled positive-displacement transfer for solids-bearing power-plant wastewater, treatment sludge and concentrated residual streams.
Controlled transfer as solids concentration changes
Power-generation wastewater systems may produce clarifier sludge, treatment residuals and concentrated process streams whose solids content varies with plant operation. Progressive cavity pumps can provide repeatable positive-displacement flow for transfer and feed duties when selected around the highest expected solids and viscosity.
Evaluate solids and chemistry together
Solids concentration, particle size and viscosity affect pump loading and inlet performance. Wastewater chemistry, treatment chemicals and temperature influence stator elastomer, rotor and seal selection. Suction piping should minimize losses as sludge concentration rises.
