Design Calculation for OzonatorOzone Dose – Raw Water Treatment : 3.0 – 5.0 ppmOzone Dose – Processed Water Additive : 1.5 – 2.5 ppmOzone Generator Capacity = Water Flow Rate (m3/hr) X Ozone Dose (gm/m3)
For Example = 25 (m3/hr) X 2.0 – 2.5 (gm/m3) = 50 - 63 gm/hr
= 25 – 32 gm/hr X 3 nos. (2 W + 1S) = 95 gm/hr (Total installed Capacity)
Recommended Ozonator Model : OG/HC –50 x 3 nos. (2 W + 1 S)
