Buying Guide For The Best Deionized Water System For Car Washing
The normal water cleans the dirt off the car body but using it might have side effects too. Hence a water deionization system helps in keeping the water quality to a level that is suitable for a car body. A detailed list of such deionized water systems was discussed thoroughly. Since some factors affect the overall performance of a deionizing water system, this buying guide will address them one by one.
1. TDS Removal Capacity
The dissolved solids in regular water are mostly mineral salts. The total count of these dissolved solids in a liter of water is known as total dissolved solids (TDS). These salts cause an increase in the acidic level of the water. Such water may react with the body paint and leave dirt traces on the surface. The deionization system removes this solid content and improves the purity of water. Every system cleans a set amount of solids before changing the filter. The normal TDS removal capacity of a deionizing system ranges between 2500 to 4500 solid particles per refill.
2. Storage
After the deionization process, the treated water needs to be stored separately. Car washing needs a large amount of treated water. The storage tank must possess a good capacity to make water available when in need. Storage also helps in keeping the treated water away from getting impure. To allow a strong water force at the outlet, the storage is responsible to keep water under pressure. Storage tanks are kept in a series to allow multiple deionization stages on the water.
3. Flow Rate
As mentioned earlier, car washing involves high water consumption. The water nozzle must receive a continuous water flow to maintain the set pressure rate. The water treatment must happen simultaneously with the flow rate. A higher flow rate and lower deionization rate lead to the release of untreated water from the nozzle. The rate is set at 0.5 gallons per minute and can be increased to 1.5 gallons per minute, depending on the system’s capacity.
4. Type Of Deionization
In the deionization process, regular water is passed through a series of resin beds. The resins can be cation (carries positive charge) or anion (carries negative charge). The solid particle being minerals tends to get attracted toward the charged resins and gets trapped, while pure water flows away. Various types of deionization processes are offered by water systems.
The weak deionization process happens when the resins consist of more acid cations and fewer base anions. Strong base ionization has the base anions quantity more than acidic cations. The mix bed deionization comprises a 60:40 ratio of acid cations and base anions. The ratio helps in maintaining the hardness of water and helps in increasing or decreasing the deionization process.
