Please provide the technical parameters for circulating water treatment
Thread Content
Please help, seniors – provide the technical specifications for circulating water treatment. I need to prepare a bid for the outsourcing of circulating water services. I really lack knowledge in this area, so I can’t write it! :L
Control standards for circulating water
Parameter | Control standard
pH value (at 25°C) | 8–9.5 | 6.8–9.5
Conductivity (in us/cm) | ≤2000 | ≤1500
Turbidity (in NTU) | ≤15 | ≤20
Calcium hardness (as CaCO3) (mg/l) | ≤600 | ≤600
Malkininity (as CaCO3) (mg/l) | ≤500 | ≤500
Chlorides (as Cl-) (mg/l, total) | ≤250 | ≤700
Total phosphate content (as PO4) (mg/l) | 1–6 | 4.0–8.0
Residual chlorine (as HOCl) (mg/l) | 0.2–1.0
Total iron (mg/l) | ≤2.0 | ≤1.0
