(To determinate an equivalent evaporation rate in the ponds a factor for salinity correction is used since the evaporation ponds will be a high dissolved solids concentration which will afeect the vapor pressure of water)

Avinash Giri:It is loss due to evaporation hence it will not consider as effleunt.

Avinash Giri:• Medical waste water.• Rainwater.• Fire protection water.• Waste to evacuate building site by truck• Drains and purgings of boilers, samplings etc• Drains of the equipment.• Drains of surface.

Avinash Giri:Based on cooment although the DM Plant designed ased on the1.8 kg/s blow down. However in normal case blow down will be only 0.9 kg/s
