Membrane Digestion Substances

During the operation of membranę systems, undesirable processes can ocur. One of such processes is scaling- formation of chemical residue, fouling (building up of sediments) or biofouling (creation of biological slimes). All those phenomena can have an adverse effect on the quality of treated water, efficiency of the used device, and in edge cases even to irreversible damage of the membranes. We offer a complex chemical program suited for cleaning membranes, which makes it easy to maintain a reverse osmosis or nanofiltration unit in perfect condition.

Description

Formation of residue and sediments on membrane systems is caused by the nature of the membranę process, and is highly dependent on the quality of the water supplied to the system, as well as the working conditions of the device. Membrane producers recommend the chemical process of flushing the membranes in cases when:
* The normalized flow of permeate drops by more than 10%,
* The normalized pressure difference between membrane inlet and the concentrate is raised by more than 15%,
* The salinity of the permeate grows by more than10%.

If membrane flushing isn’t carried out immediately after observing the aforementioned phenomena, there is a risk that the cleaning will no longer fully restore the initial efficiency of the device.

MCC offers selection and shipping of the chemicals necessary to carry out the flushing, as well as the service of membrane cleaning itself.
