➣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?
The utilization of reverse osmosis membrane filters continually grows courtesy of their cost-efficiency and high productivity. They are essentially high-rejection membranes capable of eliminating vast amounts of varying contaminants. Comparatively, they stand out from other water treatment systems and serve distinct application fields. Here are additional benefits reaped from the deployment of RO membrane filters.

➣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.
➣Which Pre-Treatment Processes are Used in Reverse Osmosis Membrane Filters?
Quite often, feed water harbors suspended particulates, volatile metals, and chemicals that could clog the RO membrane filter or corrode the equipment. Therein, reverse osmosis systems are often endowed with a pretreatment system to proactively avert premature damages. Often, conventional filters such as sediment, sand, and multimedia filters are utilized to remove the suspended matter.
Iron filters are also utilized to reduce iron concentrations while ion-exchange resins are tasked with eliminating water hardness. A chemical dosing system is also a commonly utilized technology in RO water treatment. The primary role of chemical dosing is to eradicate corrosive metals and organic chemicals.
➣What is the Size of a Reverse Osmosis Membrane Pore?
There are varying membrane-based filters currently being exploited in water treatment. The primary difference is often the size of the membrane pores. Reverse osmosis membranes have microscopic perforations characteristically measuring 0.0001 microns.
These perforations facilitate their high rejection rates when it comes to dissolved solids. Other membrane filters like ultrafiltration filters have relatively larger pores hence their application mainly involves the removal of suspended solids.
➣How Much Does Treating Water Using RO Membrane Filters Cost?
Contemporary technologies employed in manufacturing reverse osmosis membranes have fundamentally lessened the production cost of purified water. The cumulative costs of producing product water using reverse osmosis entail numerous variables such as:
- Equipment costs.
- Energy consumption.
- Installation and labor.
- Maintenance and asset depreciation.
All these variables are inconsistent resulting in varying production costs. The composition of the feed water massively impacts the product cost with more saline water accruing more operational costs. Nonetheless, the total cost of producing purified water using reverse osmosis totals $3 to $4 per 1000 gallons.

➣Do Reverse Osmosis Membrane Filters Treat Seawater?
A significant number of seawater desalination systems currently in use rely on reverse osmosis membrane filters. Specialized seawater RO systems augment the conversion of seawater into usable product water without commanding significant production costs.
Owing to the saline nature of seawater, these membrane filters have comparatively higher TDS tolerance levels (up to 45,000 ppm). However, desalinating seawater using reverse osmosis demands high pressure which increases the power consumption costs.
➣How Much Energy is Consumed by Reverse Osmosis Membrane Filters?
Reverse osmosis membrane filters are pressure-driven and they often source the necessitated pressure from high-pressure pumps. This calls for a dependable power source that can be renewable or non-renewable. In recent years, manufacturers have come up with energy-efficient RO membranes and energy recovery units that have massively lessened the power consumption of RO systems.
However, power consumption in RO membrane filters hinges on the feed water concentration, flow rate, and production capacity. The treatment of seawater for instance consumes 3kWh/m3 -6.6kWh/m3. Brackish water desalination on the other hand is relatively energy efficient.
➣What is the Flow Rate of RO Membrane Filters?
The flow rate in reverse osmosis water treatment systems is chiefly categorized as feedwater flow rate, permeate flow rate and concentrate flow rate. Ideally, the RO membranes are endowed with varying flow rates based on their application scale.

- Organic chemicals like arsenic.
- Microplastics and proteins.
➣Which Pollutants are Not Eradicated by RO Membrane Filters?
Just like all other water treatment equipment, reverse osmosis membrane filters are limited in the variety of contaminants they can remove from raw water. For this reason, post-treatment processes are enforced. Dissolved gasses like CO2 tend to increase the pH levels of water and this lowers the permeate quality. Since RO membrane filters are incapable of capturing these gasses, electrodeionization is employed.
The removal rate of microbial pathogens is also insufficient thereby obliging the deployment of ultraviolet sterilizers. The inability of RO membrane filters to eliminate ionic pollutants is remedied using ion-exchange systems.
➣How are RO Membrane Filters Different from Multi-Media Filters?
Despite being massively significant tools in water treatment applications, reverse osmosis membrane filters and multi-media filters differ tremendously. Their composition differs given that RO membrane filters are made of thin sheets of composite membranes while multi-media filters are made of varying layers of anthracite, sand, and gravel.
