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.
Membrane technology - Lenntech
Membrane technology is a generic term for a number of different, very characteristic separation processes. These processes are of the same kind, because in each of them a membrane is used. Membranes are used more and more often for the creation of process water from groundwater, surface water or wastewater.

Safe Drinking Water is Essential - Membrane Processes
Membrane Processes. Membrane water treatment systems were originally used only in desalination projects. But improvements in membrane technology have made them an increasingly popular choice for removing microorganisms, particulates, and natural organic materials that foul water’s taste and taint its clarity.. Water treatment membranes are thin sheets of material that are able to separate

Membrane Filtration for Water and Wastewater | WWD
Membrane filtration, widely used in chemical and biotechnology processes, is already established as a valuable means of filtering and cleaning wastewater and industrial process water.More recently, tubular and spiral membrane plants have begun to be used to filter impurities from drinking water in regions where conventional treatment proves to be uneconomical.

The MBR Site | What are membrane bioreactors?
‘Membrane bioreactor’ (MBR) is generally a term used to define wastewater treatment processes where a perm-selective membrane, eg microfiltration or ultrafiltration, is integrated with a biological process − specifically a suspended growth bioreactor.. MBRs differ from ‘polishing’ processes where the membrane is employed as a discrete tertiary treatment step with no return of the

Recent trends of heavy metal removal from water/wastewater
Membrane technology. Historically, the removal of heavy metals using membrane-based method was pioneered in the 1970s when Bhattacharyya et al. investigated the feasibility of using a charged ultrafiltration (UF) membrane for treating electroplating water containing Cu(II), Ni(II), and Zn(II) ions. The study showed that all metal salts were successfully rejected in accordance with the Donnan

RO Reject Water Disposal - Reverse Osmosis (RO) Water
Reverse Osmosis (RO) water treatment technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO reject water disposal is also commonly used to purify drinking water and desalinate seawater to yield potable water.
