The recent technological advancement have provided rise to breakthroughs in water reuse reclamation and wastewater treatment. This progresses have put membrane systems on the list. The systems have stood up as essential innovations embraced in treatment and reclamation plus also being among the top upgrades and expansions in wastewater plants.
Around thirty years past is when the first membrane wastewater treatments got put into practice. A prompt rise in wastewater volumes being treated in the previous decade has however been seen to turn out being of great standards and being of reusing purposes only. By facts, majority of municipal facilities on wastewater are embracing this great technology in large extents as the technology has an ability of providing unparalleled capabilities to meet the vigorous needs.
As this processes can be able to separate at molecular scales up to scales where particles are visible, it implies that large amounts of separation needs can be met by the membrane processes. This technology usually does not need a phase change in order to make separation. Consequently, the requirements for energy turn out to be low unless large amount of energy is needed to increase stream pressure so as to drive the permeating components through the membrane.
Membranes uniquely stand out being the best option as they are able to get rid of contaminants that other technologies have struggled to remove. They come very pocket friendly in cost compared to other alternatives. Less area in relation to land is also required compared to the competing brands. Their ability in replacing various units of processes of treatment with single unit has made this possible.
In application to wastewater treatment, membranes are currently getting used as tertiary advanced treatments in the removal of some dissolved species. This species are usually comprised of; phosphorous, nitrogen species, organic compounds, human pathogens, and various others. Technologies which have adopted to the use of membranes include; high and low pressure membranes and the membrane bioreactors.
The major technical challenge in using membranes for treatment of wastewater is the fouling potential which is high. Membrane fouling is usually caused by colloids, microorganisms which are not well removed using conventional pretreatment method, and the soluble organic compounds. This fouling increases the feed pressure and there is need for frequent cleaning of the membrane.
The above results to reduction in efficiency plus shorter membrane life span. Extra technical barriers likely to result comprise of complexity and increased costs for residual or concentrate disposal from high pressured membranes. To add on to this, membranes are likely to have chemical incompatibilities with certain process solution which can result to weak systems that may extend to making their lifespan turning out unacceptably short.
Membrane method of water treatment is getting favored at very quick rates. The selection is not only feasible but also smart move especially to those having plans on upgrading their plants or expanding their capacities. Benefits in situations that are land locked such as, salinity obstacles and groundwater recharge; industrial/urban reuse; agriculture; and in expansion of water supplies meeting minimal effluent nutrients.
