To apply water purification equipment well, it is necessary to first understand the water purification equipment managed by oneself. Removing and replacing filter materials is also a part of sewage treatment. What are the things to pay attention to when replacing filter materials? Below, the editor will take you to learn about common problems when changing filter materials!

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 machine 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 water seepage 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 seepage 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, seep 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. Before washing the washable quartz sand, it is necessary to ensure that the gate valve is properly opened, including the water valve and the drain valve, and close the water 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, open 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 seepage of the softener.

Frequently asked questions:

1. Before replacing the sand and charcoal, it is necessary to completely cover the electrical components near the sand tank and charcoal tank with waterproof materials such as plastic, to prevent water from entering the pump and causing it to burn out.

2. When loading sand and charcoal, the management center pipe should be sealed with raw tape to prevent sand and charcoal from entering the middle pipe.

3. When cleaning sand and carbon, it is necessary to first wash it before backwashing. During backwashing, pay attention to the air pressure gauge. If the working pressure exceeds 3kg during backwashing, it should be immediately flushed.

4. The filling volume of sand and charcoal should not exceed 70% of the total volume, in order to facilitate indoor space for backwashing.

5. Generally, the raw water pump needs to be opened for cleaning, and the working pressure of drinking water cannot be washed clean unless the working pressure of the source water is very high.
