Operational requirements for diatomaceous earth filters

1. For the first pre-coating film or the pre-coating film again after falling off, the water filtration process can only be entered after the drainage in the diatomaceous earth mixture bucket reaches the set turbidity of the swimming pool water quality. The thickness of the pre-coating film and the amount of diatomaceous earth used in the swimming pool circulating water treatment equipment are strictly implemented in accordance with the provisions of the supplied goods, and cannot be increased or decreased arbitrarily. 2. When the pressure difference between the water inlet and outlet of the plate and frame filter reaches 0.07MPA, the filter should be backwashed.

3. When the pressure difference between the water inlet and the water outlet of the filter of the candle swimming pool circulating water treatment equipment is greater than 50% of the water outlet pressure value, the filter should be backwashed. Requirements for backwashing of filters and activated carbon adsorption filters: 1. The water treatment equipment of the filter swimming pool should be backwashed one by one, and no two or more filters should be backwashed at the same time; It should be carried out after the end, and it is advisable to perform air flushing first, followed by water backwashing; 3. The flushing intensity and duration should be continuously maintained during backwashing, and the implementation process of backwashing swimming pool water treatment equipment must not be interrupted midway; 4. Backwashing After the flushing is completed, the filter flow should be not less than 1.2 times for positive washing, and the filter can be put into filtering operation only when the water quality of the primary filtration meets the "Swimming Pool Water Quality Standard". Filter operation requirements: 1. The quartz sand filter should operate continuously at a medium-speed filtration rate.

For example, at low swimming load and at night, it is advisable to operate at a filtration rate of 50% or 35%; if the filtration rate is increased, it should be increased slowly. 2. If the quartz sand filter meets any of the following conditions, it should backwash the swimming pool water treatment equipment: a. The pressure difference between the water inlet and the water outlet reaches 0.06MPA; b. The pressure difference between the water inlet and the water outlet It has not reached 0.06MPA, but the continuous operation time has reached 5 days; c. The circulating water treatment equipment of the swimming pool and swimming pool is planned to be closed for more than 5 days, and the pool water will not be drained before the stop.
