Automatic and efficient aeration fine filter is a new gravity filtration equipment, system control theory combined with various types of flow characteristics, the main equipment used UPVC material, intelligent automation of fluid control technology, full use of physical filtration methods, multi-layer filtering, automatic back Rinse, efficient oxygen, the gas-liquid control, effectively remove the water suspended solids, organic compounds in water, heavy metals and other substances, the operation will not create or add any new material, but does not change the traits of water, so it is the safest way . Reliable system operation, equipment operation and maintenance easier. Depending on the needs of users can be designed as follows: single tank, double tank modular, three pot groups, four cans modular and multi-modular gravity integrated aeration tank fine filter equipment. Gravity-free valve filter automatic and efficient application of aeration fine filter applications include: swimming pool water treatment, swimming pool water, seawater swimming pool water treatment, water treatment water park, surf water treatment, water treatment artificial lakes, pond water, landscape water purification, recycling rainwater recycling, industrial circulating water treatment, wastewater treatment and water treatment works.
