When it comes to drinking water, we often hear the term RO water; however, we do not really stop to think about what RO means. RO or reverse osmosis is basically a filtration process through which salt water can be turned into potable water. Special membrane filters are used for this process, and you must be careful while choosing a membrane filter because they can come in a variety of different configurations. For the production of potable water at desalination plants, the membrane with the RO configuration is required as Ultrafiltration and Nanofiltration cannot separate all the dissolved minerals and impurities.

However, while RO filtration and desalination plants may be the main part of the whole process, the one important process that no one should forget is the cleaning of the membranes and the filters. These filters and membranes cannot be used without proper maintenance. Although most of these filters have the ability to last at least two to three years, proper maintenance and timely cleaning of the filters can easily prolong the lifespan. That is why chemical cleaners and antiscalants are very important. There are different types of cleaners and antiscalants, so Dutco Tennant experts treat each request as different and based on that we recommend the chemical in our range which suits your needs the best.

What is an antiscalant?

After regular use of a RO filter, the membrane can experience a type of phenomenon known as scaling. Scaling is the deposition of particles on a membrane, which clogs it. This is an undesirable effect that can occur in reverse osmosis processes. Scale leads to higher energy consumption and shorter membrane life because they need to be cleaned more frequently. To avoid this, antiscalants are extremely important. It is important to inject the water with antiscalant before it is sent to the filtration system. The chemical products soften the raw water by producing a delay of time between bicarbonate and calcium magnesium. This ensures that the water molecules pass through the membrane before any scaling can occur.

What is a membrane cleaner?

Similar to antiscalants, membrane cleaners are also essential to improve the lifespan of the filters. With proper antiscalants and cleaners, the lifespan of the filters can easily go from two years to five years. This means less maintenance and replacements. A membrane biocide is basically another form of preventing agent or control agent which is used against bacterias. They are used to prevent the biological fouling of the membrane. Over time, bacteria and slime can build up over the membrane which can become extremely unhealthy. To avoid frequent cleaning, membrane biocides are used in RO filtration systems.
