Swimming pool filters use special filter sand to eliminate tiny dirt in the pool. Filter sand is used as a medium for removing dirt and is packed in the cavity of the swimming pool filter. When the control knob is turned to the "filter" position, the pool water containing suspended dirt particles is pumped into the filter pipeline, and then guided by the control switch to the water outlet of the swimming pool filter.
As the pool water passes through the pool filter, microscopic dirt is captured and filtered out by the sand bed. The filtered clean water is returned to the swimming pool through the control switch from the bottom of the swimming pool filter through the pipeline. This entire process is continuous and automatic and provides a complete cycle for the pool filter and plumbing system.
After a period of use of the swimming pool filter, the accumulated dirt blocks the water flow and weakens it. It is time to clean the swimming pool filter. For example, for the filter sand tank of Guangdong Boying Environmental Protection Equipment Co., Ltd., when the control switch is turned to the "backwash" position, the water flow becomes the reverse direction, and the water flow directly reaches the bottom of the filter cavity, and then passes through the sand. After each backwash, the control switch should be turned to the "flushing" position, and the water pump should be turned on for 0.5 to 1 minute, then turned off, and then turned to "Filter" position to restart normal filtering.
1. FILTER (normal filtration) 2. BACKWASH (backwash, discharge the dirt accumulated in the swimming pool filter) 3. RINSE (after backwash, discharge the dirt in the sewage pipe) 4. WASTE (without swimming pool filter, Direct drainage) 5. RECIRCULATE (not circulated through the swimming pool filter) 6. CLOSED (close the swimming pool filter equipment) 1. The scope of application of the swimming pool filter: The sand filter system has been used and improved for more than 50 years abroad and domestically. It is a mature and complete swimming water treatment system, mainly suitable for domestic water systems such as large, medium and small swimming pools and small and medium landscape pools. Swimming pool, water park and jacuzzi water filtration Seawater and freshwater aquaculture Industrial water purification Drinking water pretreatment Agricultural irrigation Due to its high-precision filtration, the diatomite filtration system is suitable for domestic drinking water systems and small and medium-sized private swimming pools. In recent years, the transformation of this system has been applied to the post-treatment of water quality in waterworks.
2. Features of swimming pool filter: It is made of glass fiber winding, resistant to deformation, corrosion and wear. The multi-port valve is easy to operate and simple. The unique water distributor and water collector form a uniform water flow. The underdrain drainage system has high efficiency and is easy to install. , without maintenance, the water turbidity is less than 2NTU. 3.
