The following water quality characteristics are applicable to the condenser hereto (Table ):
 

Items	Unit	Water circulating quality			Supplementary water quality standard
		Standard values	Trend
			Corrosion	Scaling
PH (25 ºC)		6.5~8.0	+	+	6.0~8.0
Electrical conductivity (25 ºC)	μS/cm	<800	+	+	<200
Chloride ion Cl-	mg/L	<200	+		<50
Sulfate ions SO42-	mg/L	<200	+		<50
