Product introduction
1. The traditional way of filtering
    Raw water ---- traditional filter1 (run) + traditional filter2 (backwashing) + the middle water tank + backwashing pump + air compressor + automatic valve + differential pressure gauge + liquid level control ---- water
2. Continuous backwashing sand filter of filtering way
    Raw water ---- Yooqi continuous backwashing sand filter + air compressor + cleaning system + volume adjustment ---- water
    Continuous backwashing sand filter is also titled flow sand filter, active sand filter, is a kind of sand filter device that it can run continuously. It differs from the traditional filter such as the backwashing and the filtering can conduct simultaneously, realize the continuous filtration, continuous automatic cleaning and updating of filtering layer. Its unique design concept has been widely used in developed countries.
Product specification
CSF-D series of continuous anti-washed sand filter specifications

structure
1. Applicable temperature is 0 ∩ ~ 65 ∩, and it can design specially above 65 ∩.
2. Cooperate with micro flocculation device, automatic door into water of highest SS is less than 120 mg/L and removal rate is more than 90%. It has reached perfect filtering effect;
3. Head loss is 0.02 MPa or less;
4. Improve the air consumption of filter material is water of per ton  is 0.15 ~ 0.2 m, and air pressure is 0.35 MPa or less;
5. Material particle size is 0.7 ~ 1.2 mm, the filter speed is 6 ~ 13 m/h. Filter material cycle time is   4 ~ 24 hours.
6. The washing water consumption is 5% ~ 10%.
Characteristics of the equipment
    Continuous anti-washing sand filter is a new type of integrated water treatment equipment, eliminating the conventional water purification process reaction, precipitation section, the device to complete the flocculation, filtration and backwash process, making the filter bed at the same time Agglomeration and separation is possible. Most of the chemical treatment process is completed in the filter bed, so continuous anti-washing sand filter device in the volume than the traditional savings of more than 80%, the amount of dosing reduced by 20% to 30%.
Scope of application
