　　4The configuration of this equipment, as well as the main control components and key equipment parts, all adopt reliable and high-performance products and technologies from abroad.

　　Ii. Process Description

　　1Working principle

　　The hardness of water is mainly composed of calcium and magnesium ions. When raw water containing hardness ions passes through the resin layer inside the water softener, calcium and magnesium ions in the water are exchanged and adsorbed by the resin, while an equal amount of sodium ions are released at the same time. The water flowing out of the water softener is softened water with hardness ions removed.

　　When the resin has adsorbed a certain amount of calcium and magnesium ions and reaches the saturated exchange capacity, regeneration is carried out. The regeneration process involves soaking and rinsing the resin layer with saturated brine from the salt tank to displace the calcium and magnesium ions in the resin and discharge them out of the tank along with the regenerant, thus restoring the resin's exchange capacity.

　　4Performance of single-valve double-tank water softening equipment

　　①Under normal usage conditions, the equipment reaches the rated water output and meets the requirements of short-term large volume1.2Double the rated water output.

　　②Dual-tank control is adopted, which can continuously supply softened water. When the water production volume is large, both tanks can supply water simultaneously.

　　③The salt dissolving system is equipped with a dedicated dilution device and a salt water filtration device to ensure that the salt solution is free of impurities and that the solubility of the salt solution reaches saturation.

　　④This equipment achieves fully automatic control and is equipped with a program controller. It can automatically control based on the influent water quality and effluent water quality requirements according to the effluent volume, complete the exchange of backup tanks, and automatically perform backwashing and other operations.

　　Iii. System Description of Softener and Equipment Selection

　　1. System Description

　　(1)Control valve

　　Adopt the United StatesPENTAIR FLECKThe fully automatic control valve means that at any time, one softener is in operation while the other is in a regenerative or standby state. When the cycle water production volume is softened and switched, each switch always results in the failure and regeneration of one water softener. The switching cycle is the regeneration cycle of the water softener. This process isFLECKThe microcomputer is uniformly controlled. The microcomputer counts the water production of the softener through the flowmeter placed after the softener. When the water production reaches the preset value, the regeneration program of the control valve is triggered. At the same time, close the pneumatic valve for the water production of the softener to prevent the regenerant from leaking to the water production end. When the standby switch is operated next time, this water production valve will be opened again. All the automated operations of the water softener are carried out in the United StatesPENTAIR FLECKThe time for forward washing, backwashing, salt absorption and regeneration is adjusted in the valve control device according to the actual data by the fully automatic control valve. The United StatesPENTAIR FLECKThe fully automatic control valve has excellent comprehensive performance:

　　aIt has good adaptability and can meet various different needs of users. It can provide different flow rates and times of water treatment equipment in various processes according to users' requirements, ensuring that the equipment operates under the parameters stipulated by the state.PENTAIR FLECKThe company offers nearly a hundred specifications of flow control boards for users to choose from. At least seven sizes of jet injectors are available for users to choose from for each type of control.

　　bIt features excellent reliability, which has been tested to exceed the current standards of the American Water Treatment Association. The design of each pressure-bearing part meets the requirements0-190psiThe cyclic pressure test250000Secondly, lead-free brass is used as the material for its valve body.

　　c, Good economyPENTAIR FLECKThe reason for its huge success in sales across the United States is that its market share has reached70%The above, apart from its excellent technical performance, is also becausePENTAIR FLECKA reasonable price.

　　(2)Soften the tank

　　The tank body is made of fiberglass reinforced plastic (FRP), with water distributors installed at the top and bottom to ensure uniform water inflow and outflow and retain resin. There are two tanks in total, providing water simultaneously. The material meets the grade requirements,Rated effluent 10 T/H.

　　(3)Resin

　　The softening tank is filled with exquisite imported cationic strong acid resin, and each tank is filled 450 LResin, the filling height of the resin is the effective volume of the tank60%.

　　(4)Work switching capacity

　　It can also be called the regenerative exchange capacity, which refers to the amount of hardness that can be exchanged per unit volume of resin in actual operation. The unit ismol/LThis value is related to the performance of the resin, the type of softener and the effect of regeneration. Ordinary is0.8-0.9mol/L.

　　(5)Regeneration cycle

　　The water production capacity of the softener from the next regeneration failure is related to the working exchange capacity of the resin, the resin filling amount, the hardness of the raw water and the working condition of the softener. This value needs to be monitored during operation. The general estimation method is as follows:

　　Periodic water production(m3)=Effective resin filling amount(L)×Resin working exchange capacity(mol/L)÷Full hardness(mg/L CaCO3)×50

　　Regeneration cycle=Periodic water production÷Rated water output

　　(6)Regenerated salt consumption

　　The salt consumption for regeneration refers to the amount of salt consumed by the softener for one regeneration cycle(Kg).

　　Regenerated salt consumption(Kg)=Effective resin filling amount(L)×160(Kg)salt
