The Ultimate FAQ Guide for Reverse Osmosis Drinking Water System.

The ravaging freshwater shortage has left over 884 million people lacking safe drinking water and over 785 million people lacking access to basic water services. This is mainly a consequence of drying up water reservoirs and pollution of water bodies.

Given that water plays an integral part in residential, commercial, and industrial activities, efforts to elevate the supply of potable water have recently heightened. Groundbreaking technologies in water treatment like reverse osmosis are undoubtedly reliable remedies to the universal water undersupply as discussed underneath.

➣What is a Reverse Osmosis Drinking Water System?

A reverse osmosis drinking water system is a water treatment unit that is pressure-driven and eradicates unwanted contaminants from water using partially porous membranes. Reverse osmosis filters are typically considered to be the best drinking water filters courtesy of their proficiency in eradicating objectionable impurities like dissolved solids and microbial pathogens. They eliminate varied contaminants hence their application is not limited to specific water sources.

Reverse osmosis drinking water systems will effectively convert tap water, brackish water, groundwater, and seawater into safe drinking water. They are customarily utilized on a residential, commercial, or industrial scale. Recent modifications have transformed reverse osmosis into a cost-efficient and highly reliable technology and this has prompted the incorporation of reverse osmosis systems in municipal water treatment plants.

➣Which Process Do Reverse Osmosis Drinking Water Systems Utilize to Treat Water?

Reverse osmosis drinking water systems purify drinking water by simply alienating objectionable contaminants from the pure water using semipermeable membranes. The process is driven by pressure, which is essentially applied to the feed water to counter the natural osmotic flow. Consequently, the water flows from the stream with a characteristically high concentration through RO membranes to the side with a relatively low concentration.

As the feedwater passes through the RO water membranes under pressure, the perforations in the membranes only permit the passage of pure water. Constituents with low molecular weights also pass through the semi-porous membranes. Objectionable impurities such as dissolved salts, minerals, bacteria, and viruses are denied passage and remain on the retentate side.

The permeate stream is harvested as Type III water, which can be polished post-treatment or instantaneously used. It is worth noting that before the feedwater is injected into the RO drinking water system, it is first pretreated using sediment filters to eliminate suspended solids that can clog the RO Membranes. This visual illustration will help you understand how RO drinking water systems function.

➣What are the Main Components of Reverse Osmosis Drinking Water Systems?

Typical reverse osmosis drinking water systems are made of several components that work cohesively to effectively purify drinking water. Get to know your system better by familiarizing yourself with the following primary components of RO drinking water systems.

● Pretreatment chamber.

Most if not all reverse osmosis systems come with a separate or integrated water pretreatment system. Typically, the pretreatment system consists of sediment filters, carbon filters, or chemical dosing systems. Sediment filters are specifically designed to remove suspended solids that might block the RO membranes, while the chemical dosing systems are tasked with eradicating minerals, chemicals, or volatile metals that can corrode or scale the system.

● Pressure booster pump.

Reverse osmosis is a pressure-driven process hence RO drinking water systems comprise a high-pressure pump. The horsepower of the booster pump varies depending on the pressure demands of the RO system.

● Reverse osmosis membrane.

The feed water is forced through the RO membranes, which are characteristically semipermeable. The membranes act as the separation media that alienates the dissolved solids from pure water. Typical reverse osmosis membrane filters have pores measuring 0.0001 microns hence they are generally regarded as high-rejection membranes.

● Post-treatment unit.

A post-treatment unit is mainly optional in reverse osmosis systems. However, post-treatment systems such as UV water sterilizers may be necessitated to fully remove pathogenic microbes. Activated carbon filters can also be utilized to eliminate bad tastes and odors.
