ABOUT
WATER MEMBRANES
Water membranes are widely used in the water treatment processes. They have become a fundamental player in separation technology because of the fact that they require no additional chemicals and their relatively low energy requirements.
Water membranes have been applied during the extraction of produced water, treatment of waste/sewage water and processing of surface water all with huge success levels. Conventional water treatment techniques are over time incorporating in their processes the use on water membranes. Commercialization of membranes was first done in the 1970s and 1980s.
Membrane technology is chiefly based on the presence of pores on the membranes that make them semi-permeable. The simple principle on which water membranes work is such that the semi-permeability of water membranes ensures that only water is allowed to pass through a specific membrane while trapping unwanted particles and substances.
In both microfiltration and ultra filtration, membranes provide an effective barrier for arresting suspended solids in water.
To aid substances to penetrate across a semi-permeable membrane the following steps are undertaken: Electric potential introduction, high pressure application and ensuring that the concentration gradient on both sides of the membrane is maintained. The surface area of the membrane also determines the efficiency of the membrane in use.
The only drawback on water membranes is that they cannot remove substances that are actually dissolved in the water such as phosphorus, nitrates and heavy metal ions. The following are categories of membranes: Microfiltration (MF), Ultra filtration (UF), Reverse osmosis (RO), and Nanofiltration (NF) membranes
Ultra filtration membranes employ polymer technology with chemically created microscopic pores that trap dissolved substances therefore eliminating the possible use of any coagulants.
