Deionized water is an improved form of regular water. Regular water comprises various types of ions and minerals that are primarily dissolved. After removing these ions, the deionized water becomes stable and reaches a pure form. A deionizing water system is a setup that helps in removing ions from water. Certain factors are discussed below that are important for deionization systems.

TDS removal capacity: Water has various elements dissolved in it. The Total Dissolved Solids (TDS) deal with the actual amount of the dissolved solids present in the supplied water. The dissolved solids comprise various types of salts like chloride, sulfate, sodium, etc. The deionization capacity gives an idea of the system’s solid removal ability. Storage Treated water from the deionizing system is stored separately where it can be used later. During car washing, water usage is very high. Therefore the storage capacity of the system must be large enough to have a good amount of water reserve. Also, the storage must help in maintaining the properties of deionized water. Type of deionization: The ion exchange process in a deionized water system is initiated by using different types of resins. The ratio of the cation resins and anion resins determines whether the process is a weak base, strong base, or a medium bed deionization process.

Keeping these factors in mind, you can select a good deionized water system unit to wash your car. The market for automotive care accessories has various options that offer good performance. We have compiled a detailed list of such options. A Buying Guide is also provided to clear any confusion related to the mentioned options and their specifications.

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.

Conclusion

The APEC Deionized Water System For Car is the most versatile option on the list. This deionized water system has dual 20-inch filters that can process water containing dissolved solids from 50 to 500 ppm. Adapting to the changing TDS level, the filtration process can treat 120 to 1200 gallons of water. To assist in cleaning the dirtiest surfaces, the pressure can be set to a maximum limit of 90 psi. The water system also supports hot water up to 100-degree Fahrenheit. It can be easily moved to the desired place using the ore-installed wheels and mounting stand. The is CR Spotless DI-120 Deionized Water System For Car also an efficient option. Using a single resin filter cartridge, it can easily handle water having a TDS count over 200 ppm. The system can treat up to 200 gallons of water in a single refill. Equipped with a battery-powered TDS meter, constant monitoring of the solid content in water is possible. The resin cartridge can also filter 75 to 1000 gallons of water depending on the dissolved solid content. All these features are available at a good price tag making it a value-for-money option. The WaterSentinel Deionized Water System For Car might be the last option here but it makes sure to perform equally with the other water systems. A total of 2 reusable resin cartridges help in filtering water 20 times per refill. It offers a constant flow rate of 0.5 or more gallons per minute.
