1Circulating water soft water treatment equipmentexplain:

The manual softened water equipment for circulating water is a manually controlled system for operation and regeneration processesion exchange softener, Supporting facilitiesManual control valveUsing sodium cation exchange resin to remove calcium and magnesium ions from water, reducing the hardness of raw water, in order to achieve the goal of softening hard water. It will also be made according to actual requirementsOne backup, one use softening water equipmentThe commonly used manual softening equipment now includes two types: manual road valve system and manual multi valve system. The former is simpler to operate, but generally the flow rate is not too large.Manual softening water systemHigh cost-effectiveness. The commonly used manual equipment requires at least one salt pump and often suffers from corrosion problems, with a large maintenance workload that directly affects the safe and stable operation of the equipment. Fully automatic equipment does not require a salt pump and has lower power consumption.

IICirculating water soft water treatment equipmentRaw water hardness:
1. When the hardness of the raw water is ≤ 3mmol/L, a time controlled type can be selected, calculated based on the equipment's water production rate;
2. When the hardness of the raw water is ≤ 6mmol/L, the selection can be based on the water production capacity of the equipment in the table;
3. When the hardness of the raw water is ≤ 8mmol/L, the selection can be based on the average water production capacity of the equipment;
4. The hardness of raw water is 8-10 mmol/L, which should be calculated based on the water production capacity of the equipment, or a multi-stage system should be used;
5. If the hardness of the raw water is ≥ 10mmol/L, multi-stage treatment must be selected, and generally two-stage treatment can meet the requirements.

IIICirculating water soft water treatment equipmentPrinciple:

Due to the fact that the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resins (water softeners) are generally used to replace Ca2+and Mg2+(the main components that form scale) in water. As the Ca2+and Mg2+in the resin increase, the efficiency of removing Ca2+and Mg2+gradually decreases. After the resin absorbs calcium and magnesium ions, it needs to be regenerated. The regeneration process is to rinse the resin layer with saline solution in the salt tank, replacing the hardness ions on the resin. The resin is then discharged from the tank with the regeneration waste liquid, and the softening exchange function of the resin is restored. Due to the fact that the hardness of water is mainly formed by calcium and magnesium, the principle of sodium ion exchange softening treatment is to pass the raw water throughSodium type cation exchange resinBy exchanging the hardness components Ca2+and Mg2+in the water with Na+in the resin, Ca2+and Mg2+in the water can be adsorbed Mg2+， Soften the water. If RNa represents sodium resin, the exchange process is as follows: 2RNa+Ca2+=R2Ca+2Na+; 2RNa + Mg2+ = R2Mg + 2Na+ ; After passing through the sodium ion exchanger, Ca+and Mg+in the water are replaced with Na+. The operation process of a general control valve is: operation, backwashing, salt suction, slow washing, salt tank replenishment, and forward washing.

4Circulating water soft water treatment equipmentcharacteristic:

The process is simple and easy to understand, easy to operate, low cost, and can be applied to high traffic needs; However, due to outdated technology, large land occupation, high operational consumption, high intensity during actual operation, severe corrosion of salt pumps, and high maintenance costs
Experience in the design, manufacturing, and installation of water treatment equipment and systems, and develop design and installation plans based on factors such as water quality and quantity. When selecting suitable equipment specifications, the following aspects are generally considered. Water usage: water usage time, average and peak water usage; Hardness of raw water: The water source comes from tap water, groundwater, surface water sources, etc. If the hardness of the raw water is greater than 8m · mol/L, it should be explained in advance; If the sediment content in the raw water is high, a filter needs to be installed.
