Process and apparatus for recovering clean water from aqueous wastes |
摘要 |
Process and apparatus for recovering clean water from aqueous wastes by evaporation while avoiding scaling and fouling as well as corrosion of the evaporator tubes. Addition of an oil, preferably a volatile oil, to the aqueous waste feed results in the formation of a coating of said oil on the surfaces of the tubes, thereby preventing corrosion and fouling and build-up of scale deposits. Volatile oil that distills over is separated from the aqueous distillate by conventional means and may be recirculated.
