Understanding Membrane Treatment

Ultrafiltration system

When it comes to water treatment, there is never a shortage of options available for consumers. Membrane filtration is one item on AdEdge’s long list of treatment solutions designed to produce clean, safe water. But what exactly is membrane treatment and how can it benefit your water supply?

Simply put, in a membrane system, water is forced through a material that is designed to only allow pure water to pass through, leaving the contaminants behind.

No matter the industry, if highly purified water is needed, membrane treatment is an ideal solution. From car washes seeking a spot-free rinse, to the pristine irrigation systems on the green lawns of golf courses, a membrane system can deliver water that is free of fluoride, nitrates, arsenic and total dissolved solids (TDS).

Looking for water that is good enough to drink? Membrane treatment is also great for potable water applications such as restaurants, hotels, schools and resorts.

Reverse osmosis (RO) and ultrafiltration (UF) are the two most common methods of membrane treatment.

“Many products fabricated require high purity water for various aspects of the process, so RO is the most cost effective technology available for reduction of TDS from well and or potable water supplies,” said Doug Craver, Western Region Sales Manager for AdEdge.

An RO system can also help water utilities stay in line with federal regulations when certain contaminants are present at levels higher than the U.S. Environmental Protection Agency’s maximum contaminant levels. And multiple contaminants are no problem, according to Craver, as RO technology can be combined with other treatment methods into one system for decontamination.

“Depending on the contaminants present, RO can be used by itself to reduce several contaminants at one time or can be used in conjunction with filtration systems to meet the required parameters,” Craver explained.

Ultrafiltration membrane systems, on the other hand, reduce organics and turbidity to bring surface water supplies up to drinking water quality. They are also used to reclaim wastewater for reuse or groundwater recharge. Large particles won’t pass through UF membranes, but ions and small organics will flow through with ease.

AdEdge designs custom membrane treatment solutions that are effective under a variety of conditions and can be combined with other AdEdge treatment technologies for complete contaminant removal. Let us design a membrane system that is right for your water supply.
