Permeate

A water treatment plant in Bahrain looked for four pumps for conveying permeate. The operator of the plant had only gained experience with centrifugal pumps in this area before. The operator was dissatisfied with the complicated and prone to failure pipeline construction which is necessary so that backflushing through the centrifugal pumps for cleaning the membranes can take place. The customer now uses four Börger rotary lobe pumps in membrane filtration. By changing the direction of rotation, the flow direction can be reversed. That way, the membranes can be cleaned by backflushing with filtered water without the need for a complicated pipeline system with several valves.
