THE IMPORTANCE OF MEMBRANE AUTOPSY

Membrane autopsy is performed to identify fillings and deposits formed on the membrane surface and chemical and mechanical damage to the membranes during the operation. Data and results obtained from autopsy tests lead to causation and thus provide solutions to reduce or eliminate operational problems.

A membrane autopsy involves several tests, and each test provides data and results to identify and quantify the filling and deposition or mechanical and chemical damage. The results of various tests are collected by experienced engineers for inference. Autopsy tests can be performed on high pressure membranes such as RO and NF as well as low pressure membranes such as MF and UF. Performing autopsies on cartridge filter pre-filters and even SDI filters provides useful information about contaminants entering the membrane system.

Identifying the problem in the early stages, before serious damage to the membranes, can be very cost-effective and prevent irreversible membrane problems and shorten their useful life.

Problems due to the presence of sediment in the membrane of the membrane

Most natural waters contain high amounts of calcium, sulfate and bicarbonate ions. In membrane purification operations with high recovery ratios, the solubility range of gypsum and calcite exceeds the saturation surfaces, which leads to the formation of sediment in the form of crystallization on the membrane surfaces. Sediment blockage reduces permeability acceleration, reduces process efficiency, and increases operating costs. It is economically best to prevent scaling of the membrane, even if effective cleaners are available to remove scale. In fact, membrane scaling occurs when particles accumulate in the membrane and connect the pores of the membrane, which increases the cost of production.
