Reverse Osmosis RO Chemicals

Pure Aqua delivers a full range of reverse osmosis chemicals, including antiscalant RO chemicals with the purpose of treating unwanted occurrences such as the formation of slime as a result of organic and inorganic substances that are found in water.

With more than 20 years in the water treatment industry, Pure Aqua has perfected the creation of high quality antiscalant which will effectively protect your membranes from fouling or scaling for a long period of time. It is important to make sure you add the RO antiscalant chemicals before reaching the reverse osmosis membranes in order to dissolve the minerals that cause fouling, such as calcium carbonate and sulfate precipitates.

Pure Aqua has over 20 years of experience as a global provider of reverse osmosis RO chemicals for the purposes of reducing scale deposits from attaching onto water treatment membranes. Once these membranes are thoroughly purified from all harmful impurities through the use of these chemicals, their performance will drastically improve within your ro system. 

Reverse osmosis chemicals (ro chemicals) to improve the performance of your reverse osmosis system’s membranes. Reverse osmosis (RO) membrane performance can be negatively impacted by impurities that build up on the membrane surface during operations. Suspended solids, microorganisms and mineral scale can foul membrane elements. These deposits can cause loss in output and/or rejection levels and reduce total system performance.

RO treatment chemicals help to greatly reduce deposits, impurities, and scale in your system’s membranes. Antiscalants, antifoulants and RO powder cleaners are specially designed chemicals that keep these contaminants from attaching to the membrane surface.
Pure Aqua, Inc. offers a full line of RO chemicals that are specially designed to help keep you membrane systems clean and free from fouling. We also can supply PTP0100 RO chemicals.

Without the usage of RO treatment chemicals, huge deposits of suspended solids within the feed water will stick on the surface of the membrane and be unable to be filtered from passing through the reverse osmosis membranes. Reverse osmosis systems work by forcing water through membranes and filtering out the suspended solids within the source water. In order for these RO systems to maintain their effectiveness, reverse osmosis chemicals must be used to make the surface smoother and not allow the mineral deposits to accumulate and clog up the membrane surface. 

Utilizing the incorrect RO antiscalants can increase risks of membrane scaling and diminishing returns in RO performance. Fortunately, employing the right reverse osmosis antiscalant at the correct dosing rate, will effectively prevent scaling issues from arising for a given time. There are available computer dosing software that forecast scaling potential and will assist in detailing the severity of membrane scaling and also provide recommendations on the ideal antiscalant dosage rate. 

Reverse osmosis antiscalants usually need extremely low dosage rates and are capable of functioning alongside other chemicals fed upstream. RO antiscalants also provide ease-of-use and security during operation, meeting all of the environmental safety prerequisites for RO treatment chemicals used in water treatment plants. Reverse osmosis antiscalants are special chemical supplements that eliminate membrane scaling and minimizes the contamination rate in the RO system. Pure Aqua offers a selection of first-rate RO antiscalants, which are NSF approved for pure cleanliness in drinking water.
