Parameters of multi-media filters.


1. Principle:

2. Effect: remove suspended solids, particles and colloid in water, reduce the turbidity of water and SDI value;

3. Technical parameters:

Water turbidity: <10NTU.

Water turbidity: <1NTU.

Working pressure: < 0.6mpa.

Operation velocity: 6 ~ 8m/h (before RO)

The intensity of water reverse washing: 30m/h.

Strength: 15L/m2•s.

Height: 0.8 ~ 2.0 200mm quartz sand.

0.4 ~ 0.6 600mm quartz sand.

0.8 ~ 1.2 400mm anthracite.

4. Structure:

The equipment is composed of body, cloth water device, water collecting device, external piping and instrument sampling.

5. Operation steps:

The speed of filtration is 10min.

Water:

(2). Reverse washing: the flow or pressure difference is usually reversed one day.

A, loosen the filter material for 3 minutes.

B, drainage

C, clean air for 3min.

D. Anti-wash for 10min.

E. Stand for 3min.
