The Ultimate FAQ Guide to Reverse Osmosis Membrane Filter

For ages, reverse osmosis technology has been extensively applied to counteract the steadily growing freshwater scarcity across the world. Consequently, the increase in the use of water treatment systems has reduced the number of people with limited access to fresh water. Owing to technological breakthroughs in the recent past, water treatment has evolved into a considerably cost-efficient affair. The following article details the application of reverse osmosis membrane filters in water treatment.

➣What is a Reverse Osmosis Membrane Filter?

A reverse osmosis membrane filter is a semipermeable membrane deployed in water treatment applications to alienate dissolved solids and other undesired constituents from water. The alienation process employed is known as reverse osmosis and is initiated by pressure which counteracts the ordinary osmotic flow.

RO membrane filters are extremely effective, explaining their preference over other water filtration systems. Customarily, an RO membrane filter will eradicate up to 99.7% of dissolved solids hence they are broadly applied in saltwater desalination. They are versatile and can be used with other complementary technologies to improve the permeate quality.

➣What are the Advantages of Reverse Osmosis Membrane Filter?

➣What are the Basic Features of Reverse Osmosis（RO） Membrane Filters?

Characteristically, reverse osmosis membrane filters are semi-permeable membranes with microscopic pores (0.0001 microns). Thanks to these microscopic perforations, they are able to alienate dissolved solids with a molecular weight of 150-250 Daltons. Their working principle is based on pressure and the end product is often high-quality permeate.

They are customarily made of composite membranes which appear as flat sheets. More specifically, the RO membranes are made of a collection tube covered by a permeable polysulfone layer wound and an active polyamide layer. This makes them high rejection membranes with scores of up to 99.7%.

➣How do Reverse Osmosis Membrane Filters Work?

Reverse osmosis（RO）membrane filters are essentially pressure-driven filters utilizing reverse osmosis technology to eradicate or massively shrink TDS levels in raw water. First, the feed water is preconditioned using multimedia filters, sediment or carbon filters, and a chemical dosing system. This eradicates suspended solids, particulates, and volatile chemicals which could potentially harm the reverse osmosis membrane.

Consequently, the preconditioned water is then forcefully pumped through the RO membranes promoting alienation. The pressure is often sourced from an integrated high-pressure pump and it serves to counteract the customary osmotic flow. In the end, a stream of filtered water is generated (permeate) and collected as potable water. The ejected dissolved solids are emitted as brine. The following video explanation summarizes the operation of RO membrane filters.

➣What are the Distinct Types of Reverse Osmosis Membrane Filters?

The classification of reverse osmosis（RO） membrane filters is chiefly based on their application scope and configuration. The varying types of RO membrane filters work best under different circumstances and their specialization is often based on the source of imminent feed water. Here are our popular RO membrane filters.

Seawater reverse osmosis membrane filters.

These systems are particularly employed in seawater filtration systems. They remove 95-99% of the dissolved salts from seawater and typically have TDS levels of 35,000 ppm. For highly salty seawater, RO membrane filters with a maximum TDS level of 45,000 ppm are employed.

Brackish water reverses osmosis membrane filters.

Brackish water RO systems utilize RO membrane filters with relatively lower TDS levels (2000ppm-15,000ppm). In addition to eliminating dissolved salts, they also remove microbial pathogens, metals, and organic chemicals.
