Rotary lobe pumps: Easy and efficient MBR filtration
Case Study: Gongchan in Gumdan Industrial Complex in Incheon

Problem

High effort to flush membranes

Solution

Rotary lobe pumps with bi-directional, pulsation free and easy to control capacity

The problem

High effort to flush membranes

Membrane filtration is the latest modern solution for wastewater treatment and base on the presence of semi permeable membranes, which act as a filter that will let water flow through, while it catches suspended solids and other substances. Over time it is necessary to clean the membranes, for example by back flush with increased flow rate at higher pressure.

Typically impeller pumps are used for membrane filtration, which means that an additonal pump, pipework and valves are needed to flush the membranes.

Advantages of the rotary lobe pumps

  • Only one pump for suction and backflushing required
  • High quality filtration through uniform and smooth flow
  • No air removal equipment required
  • Simplify devices, pipes and control
  • Significant reduction in installation space
