The working principle of deionization equipment is to remove ions and anions from water. Anion and cation exchange resins can be mixed in different proportions to form ion exchange cation bed system, ion exchange anion bed system and ion exchange mixed bed system. Mixed bed system is usually used to prepare ultra-pure water after reverse osmosis and other water treatment processes, and is used for ultra-pure water treatment in food, pharmaceutical, electroplating, electronics, chemical petroleum and other industries.

Deionizing equipment is one of the irreplaceable means to produce ultra-pure water and high-purity water. Recently, many people asked Bian Xiao: How much is a set of deionized water equipment?

The price of its pure water equipment is related to the quality of the equipment and after-sales service. The price of equipment is related to raw water quality, required water output, output water quality, whether the equipment is automatic or manual, and whether the water tank and pump are imported or made in China. These are all factors that affect the price of deionized water equipment.

So generally speaking, the price of a set of deionized water equipment ranges from tens of thousands to hundreds of thousands, mainly depending on the pretreated raw water and industry.

Different industries have different water treatment processes. The effluent conductivity of deionized water purification equipment can reach below 1uS/cm, and the effluent resistivity can reach above1mω.cm. The following are common deionized water treatment processes:

1, pretreatment → reverse osmosis → intermediate water tank → water pump →EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → precision filter → water (≥ 18mω. CM) (latest technology).

2. Pretreatment → primary reverse osmosis → dosing machine (PH adjustment) → intermediate water tank → secondary reverse osmosis (positive charge reverse osmosis membrane) → pure water tank → pure water pump →EDI device → ultraviolet sterilizer → precision filter → water object (≥ 17ω). Cm) (latest technology).

3. Pretreatment → reverse osmosis → intermediate water tank → water pump →EDI device → pure water tank → pure water pump → ultraviolet sterilizer → precision filter → water object (≥15mΩ. CM) (latest technology).
