For pure water filtration equipment, it is impossible to use it for a long time without asking. It is necessary to maintain and clean it regularly like taking care of a car. Quartz sand plays a very important role. How to replace it?

1、 Replacement process

1. Special tools are required for replacing quartz sand and activated carbon: pipe pliers, sand suction tubes, and raw tape. Conduct a comprehensive inspection of the pure water filtration equipment to see if there are any damaged parts that the customer has not noticed. If there are any, immediately inform the customer and record the main operating parameters, especially the water seepage working pressure of quartz sand and activated carbon.

2. If there is RO reverse osmosis, the server pump of RO reverse osmosis should be stopped first, then the original centrifugal water pump should be stopped, and then the seepage of the original centrifugal water pump should be turned off. When replacing sand and charcoal, it is usually done first and then the sand. As the newly installed activated carbon 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, it is also to better save time. The filling volume of activated carbon is about 60% of the total volume of the carbon filter tank. Facilitate the retention of sufficient indoor space for softeners. After installing the charcoal, seep water into the charcoal canister to thoroughly soak the activated carbon.

3. After filling the quartz sand, reinstall the pure water filtration 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. Subsequently, open the original centrifugal water pump, wash first, and then proceed to the softener. Subsequently, the front and back washing were carried out alternately. Until the water from the sewage valve responds as. Confirm that the quartz sand has been washed clean, clean the activated carbon with the original centrifugal water pump, wash the softener first, and then wash until the effluent is completely transparent without color or fine particles, and then it can be delivered for use. When cleaning activated carbon, turn off the water seepage of the softener.

2、 Precautions

1. When cleaning sand and carbon, it is necessary to first wash the softener before softening it. When softening, pay attention to checking the air pressure gauge. If the working pressure of the softener exceeds 3kg, it should be immediately flushed.

2. Before replacing the sand and charcoal, it is necessary to completely cover the electrical components near the original centrifugal water pump, such as 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.

3. Generally, it is necessary to clean the original centrifugal water pump, and the working pressure of drinking water cannot be washed clean, unless the working pressure of the source water is very high.

4. When filling sand and charcoal, the management center tube should be sealed with raw tape to prevent sand and charcoal from entering the middle tube.

5. The filling volume of sand and charcoal should not exceed 70% of the total volume to facilitate the indoor space of the softener.
