How to Calculate Percent Recovery and What Affects it in a Membrane Treatment System?

Posted by Julie Nemeth-Harn on Oct 5, 2020 1:10:00 PM

Membrane systems operating at 82% recovery will convert 82% of the total raw water input into treated permeate, with the remaining 18% being sent to waste as concentrate (or reject). The recovery rate is monitored using flow meters installed in the permeate and concentrate piping.

What is Membrane Water Treatment Technology and Why Do We Specialize In It?

Posted by Julie Nemeth-Harn on Aug 3, 2020 10:15:00 AM

Membrane water treatment is a process that removes unwanted constituents from water. A membrane is a barrier that allows certain substances to pass through while blocking others. Water treatment facilities use various types of membranes and processes to clean surface water, groundwater, and wastewater to produce water for industry and for drinking.
