Water purification equipment is a type of mechanical equipment that can filter water very well. When it is applied, it will carry out preparatory treatment, and a crucial point at the preparatory treatment level is to replace the filter material. When replacing the filter material, water purification equipment should pay attention to the following aspects:

1. Special tools are required for dismantling and replacing quartz sand and activated carbon: pipe pliers, sand suction tubes, and raw tape.

2. Before replacing quartz sand and activated carbon, it is necessary to conduct a comprehensive inspection of the machinery and equipment to see if there are any damaged parts that the customer has not noticed. If there are any, it should be immediately reported to the customer and the main operating parameters, especially the inlet working pressure of quartz sand and activated carbon, should be recorded.

3. Stopping the operation of machinery and equipment: For those with RO reverse osmosis, the server pump of RO reverse osmosis should be stopped first, then the raw water pump should be stopped, and then the inlet of the raw water pump should be turned off.

4. When changing sand and charcoal, it is generally done by first changing the charcoal and then changing the sand. As the newly installed activated charcoal needs to be soaked in tap water to make it sufficiently wet, remove the gas between the charcoal particles and the internal gaps, and prevent the charcoal particles from floating on the sea, which is also to better save time. First, put a small amount of water at the bottom of the charcoal filter tank, and then fill it with activated carbon.

5. The filling volume of activated carbon is about 60% of the total volume of the carbon filter tank. Facilitate the retention of sufficient interior space for backwashing. After installing the charcoal, pour water into the charcoal canister to thoroughly soak the activated carbon.

6. Before replacing the quartz sand, a small amount of water should also be introduced into the sand tank. Fill the quartz sand in the order of large sand below and small sand above. The filling volume of quartz sand is about 80% of the sand tank.

7. After filling the quartz sand, reinstall the machinery and equipment. Washable quartz sand, before washing, it is necessary to ensure that the gate valve is properly opened, namely the inlet valve and the outlet valve, and close the inlet valve of the activated carbon. Then turn on the raw water pump, wash first, and then backwash. Subsequently, the positive and negative washing were carried out alternately. Until the water from the sewage valve responds as.

8. Make sure that the quartz sand has been washed clean, use the raw water pump to clean the activated carbon, wash it first and then backwash it. After washing until the effluent is completely transparent without color or fine particles, it can be delivered for use. When cleaning activated carbon, turn off the water inlet of the softener.

The above are the precautions for replacing filter media in water treatment equipment, hoping to be helpful to everyone.
