Filter Press
Problem: The Franklin Brine Treatment Plant uses a Wilden diaphragm pump to charge a filter press with brine water oil/sludge. When first charging the filter press with the diaphragm pump, the filter screens are clean and product flow is exceptionally fast. Because of the reciprocating design of the pump, product flow is pulsating. The pulsating flow produces pressure spikes which cause damage to the filter screens. The piping is CPVC plastic because the brine water is corrosive. The pulsating flow also causes vibration which results in leaky pipe joints.
