Sand carbon filter replacement filter material steps and matters needing attention

Quartz sand filter and activated carbon filter is commonly used in water treatment equipment, to run in a certain time, just to follow change of quartz sand and activated carbon filter material, the following introduction to quartz sand, activated carbon filter filter material replacement steps:

1, replacing quartz sand, activated carbon tools required: tongs, sand suction tube, tape.

2, replace the quartz sand, activated carbon to the equipment to conduct a comprehensive inspection before you, to see if the customer's equipment have already found no bad parts, if any should be timely to customers, and record the operation parameters, in particular, quartz sand, activated carbon water pressure.

3, equipment shutdown, first of all, have a reverse osmosis to stop the reverse osmosis host pump, stopped the original water pump again, then close the water pump into the water.

4, changing sand carbon is usually put in carbon in sand, because, just loaded activated carbon, first to be soaked in water for, make its full wet, exclusion and internal gaps between the granular air, make the granular not float in water, but also to save time. In the first place in a small amount of water at the bottom of the carbon filter, and then put the active carbon into.

5, activated carbon loading volume is about 6% of the carbon filter tank volume. In order to leave enough space of backwashing. After loading the carbon carbon pot into the water, the water to soak activated carbon completely.

6, in quartz sand before also should inject a small amount of water in the sand tank, according to the large sand, below the little sand in the above order loading quartz sand, quartz sand filling volume is about 80% of the sand tank. After the

7, quartz sand filling, installed equipment. Wash quartz sand, before washing to confirm whether the valve opening on the right is fill valve and valve, inlet valve closing activated carbon. Then the original water pump, is washed in the wash. Then the positive and negative wash alternates. Until the water clarification as to waste water valve out.

8, confirmed quartz sand has been washed, the original water pump clean activated carbon, is to wash first, then backwashing, wash to water colorless, no fine particles can be put into use. Washing the activated carbon to shut off the water softener. Attention

1, before changing sand carbon, want to use waterproof things such as plastic fully covered the original not the pump from the sand tank, carbon tank near the electrical components, prevent water from entering the pump and make the pump to burn out.

2, when filling sand carbon, center pipe should use tape to seal, prevent sand carbon into the tube.

3, when cleaning sand carbon, must first is wash again backwashing, attention should be paid to observe the pressure gauge during backwashing, if pressure is more than 3 kg, when the backwashing immediately hit is washing.

4, sand carbon loading volume should not exceed 70% of the total volume, in order to have a backwashing space.

5, generally should be original not pump clean, running water pressure is not enough to wash, unless the raw water pressure is very high.
