Water containing TDS concentrations below 1000 mg/litre is usually acceptable to consumers, although acceptability may vary according to circumstances. However, the presence of high levels of TDS in water may be objectionable to consumers owing to the resulting taste and to excessive scaling in water pipes, heaters, boilers, and household appliances (see also the section on Hardness). Water with extremely low concentrations of TDS may also be unacceptable to consumers because of its flat, insipid taste; it is also often corrosive to water-supply systems
The pH for drinking water should preferably be less than 8.0
severance: WHO
Ph will be 6 to 7
And TDS(total dissolve Solid) will be 230 mg per litre
Conductivity is 400
PH 6.9 to 7.3 & TDS 110 to 140
PH- 7.5 to 7.9 & TDS-4500
THE PH SHOULD RANGE BETWEEN 6 TO 7 WHILE THE TDS SHOULD RANGE BETWEEN 200 TO 600.
pH=6-7 Conductivity=2S/m,TDS=400ppm
Water program treatment (pH, conductivity, TSD, inhibitors level or dispersants) for cooling tower depends on metallurgy systems, temperature and make up water qualify.
pH of the water should be 6.5-8.5
Tds of the swater is usually -300-400 mg/lit
conductivity of water vary as tds.
The proportion of TDS in the water should not exceed 1000 mg / L, according to the specifications in place, and when exceeding this value should be treated by R.O unit If there is a good quality water source the best treatment by mixing, concerning the degree of acidity (pH) should not exceed 8.
