1.Operators should adjust the discharge volume in time so that the concentration times are within the index.
2.Every week, a large amount of sewage should be discharged once. Discharge the sewage from the drainage pipe at the bottom of the tower.
3.Regularly analyse the calcium loss rate. Calcium loss rate is used to assess the system scaling situation, in general, calcium loss rate ≤ 20%.
4.Monitor the cooling water analysis once a week. Main analysis items: pH, conductivity, total phosphorus, total iron, total hardness, total alkalinity, etc. Record the daily dosing, water replenishment, drainage and chemical analysis.
5.Control index water treatment standards (international): carbon steel corrosion rate ≤ 0.125mm/a: copper corrosion rate ≤ 0.005mm/a: fouling thermal resistance ≤ 1 × 10K/W. Process control index: pH ≤ 9.2: turbidity ≤ 15.0mg/L; conductivity ≤ 2000μs/cm; total iron ≤ 1.0mg; total phosphorus ≥ 6.0mg/er: calcium loss rate ≤ 20% .
