Parameters of multi-media filters.
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.
Height: 0.8 ~ 2.0 200mm quartz sand.
0.4 ~ 0.6 600mm quartz sand.
0.8 ~ 1.2 400mm anthracite.
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.
(2). Reverse washing: the flow or pressure difference is usually reversed one day.
A, loosen the filter material for 3 minutes.
C, clean air for 3min.
D. Anti-wash for 10min.
E. Stand for 3min.
F, washing for 20 minutes.
