At present, the filters in swimming pool equipment in the domestic market are mainly divided into three categories: one is sand tube filter; Second, gravity filtration; Three. Diatomite filter.

Use of sand cylinder filter

When the pressure gauge on the multifunctional head of the sand cylinder reaches 0.3-0.4, it should be backwashed, that is, the filtered stolen goods in the sand cylinder should be cleaned.

Backwashing:

① Turn off the water pump and adjust the sand cylinder head to the backwashing position.

(2) Turn on the water pump and run for 5-7 minutes until the water in the transparent observation window of the sand cylinder head is clean.

③ Stop the water pump.

Rinse:

① Stop the water pump and adjust the sand cylinder head to the flushing position.

② Turn on the water pump and run for 2 minutes.

(3) Stop the water pump and adjust the sand cylinder head until the sand cylinder head is filtered.

At this point, the cleaning of the sand tank is over.

Sand tube filter is the most widely used equipment in swimming pool equipment, and the filter you mentioned should belong to this category.

Gravity filter

? Gravity filter can be backwashed automatically, so it can't be cleaned and cleaned manually.

Because this filter is automatically backwashed, when there is too much dirt in the tank, the purification capacity of the equipment will decrease, but manual backwashing cannot be carried out, and the water quality of the swimming pool will get worse and worse before backwashing, so we can only wait until the equipment is automatically backwashed.

Diatomite filter layer

Professionalism is too high, and pre-coating film is needed after backwashing, so I won't introduce it for the time being. You can find a professional to give you training.
