Valeting services for cars, trucks and motorbikes require on demand purified water for initial wash downs, diluting cleaning chemicals and final rinses to leave a spot and streak free shine. The multiple ways in which pure water can be applied within this industry calls for a stable supply that has the ability to regenerate both throughout a day of cleaning and overnight. Water treatment systems boast a superior quality of purity over raw water deionisation due to the efficiency of the reverse osmosis process. These are typically stored in a plant room, where tanks of pure water are filled, ready to be drawn to the point of use through spray nozzles.
The most efficient way of producing this scale of purified water is using a reverse osmosis system, pre treated using particle and chlorine filtration to prolong the service life of the RO membrane. This process will remove ~99% of ions, salts and other contaminants, ready for a final polishing DI resin stage. Deionised water is of ultra pure quality, meaning it attracts contaminants such as dirt to stabilise itself, leaving surfaces without any build up. The use of RO water during deionisation will also prolong the service life of the resin used, saving money and time on resin replacements.
