Most vehicle washing systems are housed in a plant room including the filtration and water treatment system. The majority, fill up a water storage tank from this system and apply to the vehicle via spray nozzles near the brushes.
To reach the desired water quality levels for a spot free result, particles, organics and chlorine are all removed before the RO membrane removes the majority of ions and salts.
This RO water is sometimes used as the final rinse, however for the complete removal of total dissolved solids (TDS) then deionising resin is used. Some operators also reclaim the effluent from a sump beneath the vehicle and treat this before re-using.
Stages of Filtration & Water Treatment
Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.
Chlorine and Organics Removal
Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.
RO Water Production
Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.
The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.
Devices that measure the conductivity of water between 2 probes provide a good indicator of the ions and salts content.
SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Boasting WRAS approval over the ESP, the TruDepth Standard is the best value option for general particulate reduction. With a recognisable mini-grooved construction, the SSP has a higher surface area and enhanced dirt holding capacity over the TruDepth Economic cartridge (ESP).
SPECTRUM 870 Economic Carbon Block Cartridge
SPECTRUM Economic carbon cartridge removes chlorine, chemical and organic taste as well as odour and appearance removal. Great for pre-filter in applications such as RO.
SPECTRUM Reverse Osmosis System
SPECTRUM RO Systems designed for commercial & industrial operators. 4 systems available to meet RO production levels of 150 to 1250 litres per hour.
