Multi-media filters, activated carbon filters, security filters and resin tank model selection mainly depends on the RO terminal water flow to RO equipment to calculate the utilization rate of water pretreatment flow. General small RO water utilization rate of about 50 - 60%, large systems in 75%, up to 80%.



Examples of related issues:

Assuming that a RO water production 3 tons / h, recovery rate of 75%, pretreatment water production 4 tons / h, without considering the rate of pretreatment preparatory water;


Multi-media filter


◆ Multi-media filter general design flow rate to take 8 - 10m / h, where the water production of 4 tons / h, according to Q = SV


Q flow, S tank cross-sectional area, V design flow rate, S = π R ^ 2 tank diameter d = 2R] can calculate the diameter of the tank, the height can check the manufacturer's manual.


Activated carbon filter


Activated carbon filter general design flow rate of 10--12m / h, where the water production of 4 tons / h, according to Q = SV [Q flow rate, S tank cross-sectional area, V design flow rate, water production of 4 tons / h, S = π R ^ 2 canister diameter d = 2R] can be calculated the diameter of the canister, the height of the manufacturer's manual.


Softener


◆ The general design flow rate of the softener is taken as 15--20m/h, where the water production is 4 tons/h, and the diameter of the tank can be calculated according to Q=SV [Q flow rate, S tank cross-sectional area, V design flow rate, S= π R^2 tank diameter d=2R] and the height can be calculated by checking the manufacturer's manual.
