To apply water treatment equipment well, one must first understand the water treatment equipment they manage. Changing sand and carbon is also a part of sewage treatment. What are the things to pay attention to when changing sand and carbon? I will discuss common issues with sand and carbon replacement for you regarding the water purifier below.

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.

Above is the common issue of sand and carbon replacement in water treatment equipment, hoping to be helpful to you.
