Water that comes from a number of sources is treated using reverse osmosis (RO), all over the world. This method gives its operator a lot of flexibility, allowing them to treat everything from the brackish water in some lakes and rivers, to the sources of secondary municipal and industrial effluent.
The multiple pretreatment processes for RO membrane treatment are one of the most important, since the water quality varies depending on its source. Specialized electrocoagulation technologies might be quite helpful, throughout this pretreatment process.
Difficulties in RO Pretreatment
Reverse osmosis technology derives its primary application from membrane technology. Several obstacles must be overcome throughout the membrane pretreatment process.
The following difficulties in the reverse osmosis pretreatment process must be resolved:
· Metal oxide-induced scaling and membrane fouling
· Inorganic salts and colloids
· Organic materials such as silica, magnesium, and calcium
· Contamination or obstruction by inorganic particles
The performance of the RO system will be severely hampered, if the aforementioned factors are not appropriately handled, throughout the RO pretreatment process. This can occasionally lead to a total membrane breakdown, which is typically the result of poor pretreatment design and performance. This makes the incorporation of pretreatment technology sufficient, for safeguarding the RO membrane filters valuable, as well as necessary.
RO Pretreatment using electrocoagulation process
The development of electrocoagulation as a reverse osmosis pretreatment method for RO systems, in certain applications dependent on the feed source water quality, is pioneered by engineers at Netsol Water, a specialized leader in the global water treatment business.
Organizations now need to lessen their environmental footprint among other things, due to the shift towards sustainability. In order to construct the technology, in a way that provides its operator with enormous value for reverse osmosis pretreatment applications, Netsol has taken the lead in the development of workable procedures.
How RO Water is pre treated using electrocoagulation?
In order to remove biological, organic, and inorganic substances from the water supply, electrocoagulation is a procedure that does not require the use of any chemical coagulants; instead, the coagulants are created in-situ through the dissolving of sacrificial electrodes.
Due to the unique properties of electrocoagulation, it has been recognized as a good pretreatment, for contaminated input water coming from brackish, seawater, and tertiary wastewater sources, before it enters reverse osmosis systems.
Reduction in treatment costs using electrocoagulation as a pretreatment
Pretreatment chemicals and membranes are included in the operational costs of RO systems. Netsol can replace traditional chemical coagulation treatment with greater outcomes, and possibly higher RO system recovery rates, by incorporating advanced electrocoagulation into the pre-treatment process. The operation costs for the membrane system, such as membrane chemicals and membrane filter replacement, are reduced as a result of using this strategy.
