Installation and operation of quartz sand mechanical filter


1. When filling quartz sand, you must carefully check the tightness of the filter caps to ensure that each filter cap is fastened correctly before filling quartz sand. 2. When constructing on the concrete foundation of the pressure filter, holes should be reserved according to the position of the filter foot holes, and the lifting of the filter and the assembly of the connecting pipe should be carried out after the foundation reaches the design strength. 3. At the initial stage of filter operation, the operation experience should be gradually explored according to the local water quality conditions to determine the type and dosage of coagulant, the opening degree of the drainage gate valve during backwashing, etc.

4. During the operation of the filter, the turbidity of the influent water shall not be higher than the index specified in the design, and backwashing shall be carried out according to the design requirements, otherwise, the operating cycle may be shortened or mud balls may be formed in the filter layer, which may seriously affect the effluent water quality. 5. When directly filtering, the coagulant should be prepared to a certain concentration and added before the pump. 6. Flushing steps: a. Flushing: Close the water inlet pump and water inlet gate valve, open the drain gate valve, and carry out backwashing according to the flushing intensity and flushing time required by the design.

b. Resume operation: Close the drain gate valve, open the water inlet valve and air release valve, start the water inlet pump, wait for all the air in the filter to be exhausted, then close the exhaust valve, and the filter will resume normal operation. 7. When several pressure filters are operated in parallel, gate valves should be installed on the inlet and outlet pipes. Poolking is the best swimming pool equipment manufacturer and supplier in China.
