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.
The early usage of the membrane wastewater treatment was in practice about thirty years ago. However, in the past decade, a rapid increase in volume of wastewater being treated has been experienced to be of exponentially high standards and it is typically for reuse purpose. As a matter of fact, many municipal facilities on wastewater treatment are adopting this technology to an even larger magnitude as the technology provides unparalleled ability to meet rigorous requirements.
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.
The ability of membranes to remove stubborn contaminants that become difficult for other technologies to remove makes the membranes to uniquely tower above the others as a great option. They are very economical in costs in comparison to other alternatives. They in addition need only very minimal land area compared to other competing brands. Ability to replace several treatment processes units using just a single unit has made this a possibility.
For applications in wastewater treatment, membranes are in the current times being used as tertiary advanced treatment in the removal of species that have dissolved. Such species include, organic compounds, nitrogen species, phosphorous, human pathogens, among others. Technologies using the membranes include; membranes bioreactors, low-pressure membranes and the high-pressure membranes.
Among the major challenge posed by usage of membranes in wastewater treatment is high potential fouling. This kind of fouling is normally caused by colloids, tiny organisms that have not been properly removed by the regular pretreatment methods, and also some soluble organic compounds. The fouling usually increase feed pressure leading to need for frequent cleanup 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.
Adaptation of wastewater treatment by the use of membranes is on the increase. The option is not only viable but in most cases also a smart move especially when considering to upgrade plants and expanding capacity. This approach is beneficial in land lock situations such as agriculture, urban or industrial reuse; recharge of groundwater and salinity barriers; and also in the augmentation of mobile water supplies that meet low effluent nutrients.
