How a Commercial RO Water System Works

September 21, 2018 4:37 pm Leave your thoughts

If you run a business that requires a constant stream of pure, contaminant-free water, simple water filtration systems might not provide enough water or produce high enough quality to meet your standards. Instead, many commercial businesses choose to use a commercial RO water system in Cincinnati, OH to purify their water long-term.

Commercial RO water systems use a process called reverse osmosis (RO) to remove almost all of the contaminants present in your water supply. In simple terms, they force pressurized water through a membrane to filter out pollutants, including nitrates, pesticides, sulfates, fluoride, bacteria, pharmaceuticals and more. These contaminants get into your water supply through lakes and streams, and even come from within your water pipes, and can make your water taste different or even interrupt chemical processes using water.

Commercial RO systems are easy to maintain and cost-effective for many commercial businesses requiring pure water. Plus, they are fully automated, meaning you can get your supply of water with little to no work required for years to come. If you are interested in investing in one of these systems for your business, it’s important to understand how they work and what kind of water they produce.

The components of RO systems

There are a few major components of RO systems that contribute to their effectiveness.

A high-pressure pump and motor help pressurize the “feed water” that is pushed through the membrane. The pressure required for your system will largely depend on how contaminated the water is—more contaminants will require higher pressure. A series of filters provides varying levels of filtration before and after the RO membrane.

A semi-permeable membrane is the main RO membrane that allows some atoms through, but not all, and will trap the dissolved inorganic solids from the feed water.

The process of RO filtration

Feed water will be pressurized using the pump and motor, then pushed through the RO system.

First, water goes through a pre-filter, which is a sediment filter that traps dirt and larger pieces of sediment. These larger pieces need to be removed because they can cause damage to the finer membranes later in the process. The water may also go through other pre-filters, depending on the design of the commercial RO system.

Next, water will be pushed through the RO membrane, where almost all of the contaminants will be removed. The pure water will flow through to the other side and continue, while the contaminants are left in a waste stream of water, which is drained out. RO systems use cross flow filtration, which allows the stream of wastewater to flow across the membrane, reducing buildup on the membrane and draining in another direction as the purified water flows out to be collected. Some systems can be designed to collect wastewater and recycle it through the RO system again to save water.

Finally, water will go through a final post-filter. This final filter is the last opportunity for the RO system to trap any remaining minerals and remove them before water is pushed through.

The purified water is then collected in a tank for use by your business later.
