In the process of membrane treatment, the flow rate of the forward discharge and backwash processes is very different, and a frequency converter is required to adjust the flow rate. The rotary lobe pump has a proportional relationship between the flow rate and the rotational speed, and the flow rate is completely controllable. No pollution: For the membrane treatment of drinking water, the water quality has been significantly improved after the membrane filtration, so it is not allowed to damage the good water quality during the pumping process.
