Shallow sand filter

Equipment introduction：

The shallow sand filter is composed of one or more standard high speed sand cylinder units with unique internal water distribution and water collectors, and has a unique automatic flushing valve, which enables backwashing of multiple standard high speed sand cylinders individually during normal system operation, with fully automatic program control. It has the advantages of small backwashing water consumption, easy installation and easy operation; the equipment has a large flow rate and requires no maintenance; according to different user requirements, there are two series, vertical and horizontal, which are suitable for water quality treatment needs in many fields.

1.Influent turbidity: <30FTU

    effluent turbidity:<10FTU

2. Working temperature: 5-60°С

    Working pressure:≤0.6MPa

    Inlet water pressure: ≥0.3 MPa

    Backwash back pressure:≥ 0.3 MPa 

(if ≤ 0.3MPa, a regulating valve needs to be added to the outlet main pipe)

Pressure difference between inlet and outlet: 0.02-0.05MPa

3.Control mode: manual control, automatic control (time)

4.Tank material: Q235B, 304, 316L, carbon steel with rubber lining. Water cap material: ABS, 304, 316L

5.Single flow rate: 0.5m3/h-230m3/h

6. Input voltage: AC22OV± 10% 50-60HZ

7. Output voltage: AC24V/ AC220V

8. Load power: 24W/1A

9. Power of each circuit: ≤50w

Shallow sand filter  advantage

1. High filtration speed and low pressure loss completely solve the problems of slow filtration speed and low flow rate of ordinary mechanical media filters.

2. Modular setting, small footprint, less piping, and low investment.The floor area is reduced by more than 40%, and the amount of piping engineering is reduced by more than 50%.

3. Manual, semi-automatic and fully automatic backwashing options are available to fully meet your needs.
