Sewage Treatment

Sewage Treatment

Problem: The Maquoketa, Iowa sewage treatment facility uses a twin disc type reciprocating pump to transfer pretreated sewage sludge from a clarifier to a digester. The twin disc pump is ideal for this application because this type of pump has no valves that can clog or restrict flow. Each disc of the pump transfers about one gallon of liquid with each stroke. The reciprocating action of the pump causes the discharge pipe and other components in the system to vibrate. This constant shaking causes joint leakage and premature failure of instrumentation. Pipe support brackets have been pulled loose from the wall.

Problem: The City of Colorado Springs WWTP uses Abel mechanical double diaphragm pumps to transfer sludge throughout their facility. The pump is ideal for their application due to the solids handling capability, and the fact that the pump is a positive displacement pump which allows the flow to be metered. The reciprocating action of the pump causes excessive pulsation in the discharge piping. The constant pulsation has caused broken pipes, failed gaskets, damaged valves, and has pulled pipe supports from foundations.
