New Wave Industries has been the leading manufacturer of reverse osmosis systems for the carwash industry for over 30 years. With continued innovation and engineering, we strive to continue to uphold this place within the industry. Purchasing and installing a reverse osmosis system in your carwash is the best way to achieve superior water quality for your wash, leaving customers' vehicles spot free and providing a high quality wash every time. Keep reading to learn how the PurClean reverse osmosis systems work for the carwash operator.
The PurClean system begins purifying incoming water starting with the carbon tank. The carbon tank comes standard on all PurClean units, however it can be upsized in the event that the receiving site has high levels of chlorine in their water. This is important because the main function of the carbon tank is to remove the chlorine from the incoming water. The water flows into the tank and the chlorine molecules stick to the carbon media inside of the tank. This makes maintenance on the carbon tank important, because you want to make sure that the carbon media inside of the tank is clean enough to remove these chlorine particles from the incoming water. The water then exits the tank and heads for the prefilter, also standard on all PurClean systems. The PurClean prefilter takes the incoming water and removes all particles that are larger than 5 micron (a single strand of human hair is 50-70 microns). Again, maintenance and replacing this prefilter is important to maintain optimum performance of the unit.
Once the incoming water has finished making its way through the prefilter, it flows through the PurClean water stabilizer. The water stabilizer (which is also standard) eliminates the need for a water softener in applications where the incoming water is 25 grains or less in hardness. This is important because water softeners can be expensive to maintain and are not ideal because of their impact on the environment. The PurClean water stabilizer works by physically removing the particles from the water. It uses an ionic process to separate out the dissimilar metal molecules which then stick to the stabilizer bar itself. Once again, it's important to clean the water stabilizer bar according to your maintenance schedule to ensure proper function.
Once cleaned by the water stabilizer and pumped through the booster pump on the unit, the now pressurized water enters the membranes. The number of membranes will be dependent on the size of the RO unit - more membranes means higher output. The water flowing through the membranes is further filtered to remove particles such as calcium and magnesium. Water that is successfully purified then exits the membranes and flows through the flow meters and into the RO water storage tank. From here, the water is pumped out of the tanks and into the wash applications. Water that does not meet the high quality standards for PurClean spot free water, or reject water, is also pushed out of the membranes but then flows back into the recirculation valves to either be reprocessed into spot free water or pushed out of the system. Depending on system specifications, the product to reject ratios can be up to 4:1.
Water quality is essential to a quality carwash and a PurClean reverse osmosis system can ensure that your customers are leaving with a spot free vehicle every time. Contact us today for more information and to determine which PurClean system is right for you.
