Hi,
My question may seem impractical, but need help to avoid any confusion.
What is the limit of Chemical Oxygen demand of boiler feed water?
In IS 10496:1983, other parameters like hardness, alkalinity,pH,TDS, Silica, ammonia, iron, copper, dissolved oxygen are given but COD limit is not specified.
If recycle water has low COD up to 50 ppm, can we recycle it?
Regards,
