Purified water equipment, softened water equipment, and ultra pure water equipment are common equipment in water treatment equipment. Softening water equipment is a treatment equipment that removes Ca and Mg ions from water, reduces water hardness, and softens water. The effluent quality of the softened water equipment is good, and the system operates stably, which is used by many enterprises; The effluent quality of ultra pure water equipment is good, suitable for the production needs of many enterprises, and the scope of use is gradually expanding.

1. The tools required for replacing quartz sand and activated carbon in the equipment include pipe clamps, sand suction pipes, and raw tape.

Before replacing quartz sand and activated carbon, the equipment should be inspected to see if there are any undetected damaged parts on the customer's equipment. If there is, it should be explained to the customer in a timely manner and operating parameters should be recorded, such as the inlet pressure of quartz sand and activated carbon.

3. Equipment shutdown: If there is reverse osmosis, the main reverse osmosis pump should be stopped first, then the raw water pump should be stopped, and the inlet water of the raw water pump should be closed.

4. Sand and carbon replacement generally refers to changing the carbon before sand replacement, as the newly installed activated carbon needs to be soaked in water to make it more moist, solve the air between and inside the carbon particles, and prevent the carbon particles from floating on the water, saving time. Place a small amount of water at the bottom of the carbon filter and then load activated carbon.

5. The loading capacity of activated carbon is about 60% of the total volume of the carbon filtration tank. In order to leave sufficient space for backwashing. After the charcoal is installed, pour water into the charcoal jar to soak the activated carbon in water.

Before replacing quartz sand in the water treatment equipment, a small amount of water should be injected into the sand box. The filling sequence of quartz sand is lower large sand and upper small sand. The filling amount of quartz sand is about 80% of the filling amount of the sand tank.

7. After filling with quartz sand, reload the device. Washable quartz sand. Before cleaning, keep the valves open correctly, that is, close the intake valve, upper exhaust valve, and activated carbon intake valve. Then turn on the raw water pump, wash first and then wash. Then alternate between positive and negative washing. Until the water in the wastewater valve clarifies.

8. The water treatment equipment should ensure that the quartz sand has been washed clean. Clean activated carbon with an open water pump. Wash first, then wash again. Rinse until the water is transparent. Fine particles cannot be put into use. When cleaning activated carbon, close the inlet of the softener.
