First, the hair filter

    1. The finished hair filter should be used first, but detailed information should be requested to check whether the total area of the filter (mesh) hole (mesh) eye meets the requirements of the specification.

    2. The shell should be made of corrosion-resistant materials, such as FRP, stainless steel, or copper. If cast iron or carbon steel is used, anti-corrosion treatment should be performed, and anti-corrosive paint or lining anti-corrosive material that meets sanitary requirements should be applied. The working pressure of the shell should not be less than 0.35MPa.

    3. The material of the hair filter (barrel) is generally made of copper, stainless steel or plastic.

    4. Hair filter requires net (cylinder) to be cleaned daily, so the structure of the shell should be simple, flexible in loading and unloading, and good in sealing performance.

    5. The total area of the holes (mesh) of the filter (cylinder) should not be less than 2.0 times the cross-sectional area of the connecting pipe. The diameter of the mesh of the filter should be 3-4mm, and the diameter of the filter should be 10-15mm.

    Second, circulating water pump for swimming pool water treatment equipment

    1. The number of circulating water pumps should be configured according to multiple pumps running at the same time to reduce the capacity of standby pumps.

    2. Circulating water pumps should be made of integrated copper, stainless steel or high-strength plastic pool pumps with large-capacity front hair collectors.

    3. When using a cast iron circulating water pump, the impeller should be made of copper or stainless steel, the mechanical seal should be a corrosion-resistant material, and the motor should be fully enclosed.

   4. When conditions permit, a low-speed circulating water pump should be used to facilitate flow adjustment and reduce noise.

    5. Water pumps and pipelines shall be provided with measures to reduce vibration and reduce noise.

    6. The speed of the suction pipe of the pump should be 1.0 ~ 1.5m / s; the speed of the outlet pipe of the pump should be 1.5 ~ 2.5m / s.

    Because of this, swimming pool water treatment engineering technology is becoming more and more skilled, the workload of water treatment is low, but the effect is high. So what is the specific process of swimming pool water treatment.

    1. Algae killing and algae suppression: The agent used in the market is mainly copper sulfate. Copper sulfate, also known as alum, is an algicide. It is a blue asymmetric triclinic crystal or powder, easy to melt and water, can kill, anti-microbial growth, and can make the pool water into a seawater-like blue.

    2. pH adjustment: Generally, the pH is increased, and sodium hydroxide and sodium carbonate are mainly selected. The effect is very good.

    3. Water purification agent: Also called swimming pool water purification agent, there are generally two types of swimming pool clarifiers, namely polyaluminum chloride and clear water clarifier. The former requires suction, the latter does not.

    4. Suction: You need to choose a good fully automatic dirt suction machine
