3 water quality requirements

The main water quality indicators of seawater cooling water shall meet the requirements of Table 1. Table 1 Main requirements for water quality of seawater cooling water Item unit allowable value Calcium ion (Ca2) mg/L ≤1000 Magnesium ion (Mg2) mg/L ≤3200 Zinc ion (Zn2) mg/L ≤2 Chloride (Cl-) mg/L ≤42000 Sulfate (SO42-) mg/L ≤ 6000 Dissolved solid g/L ≤ 100 Isozyme CFU/mL ≤ 5.0 × 105 Note 1. The permissible values for Ca2, Mg2, Cl-, SO42-, and isoquant are derived from 6.1.2 and 6.1.3 of GB/T 23248-2009. Note 2. The permissible value of Zn2 is derived from GB 8978-1996 Table 4 Class II pollutant maximum allowable discharge concentration level standard. Note 3. The permissible value of the dissolved solids is determined by the maximum concentration of N = 2.5 times the actual seawater cooling. ...
