Abstract

Purification or clarification of large quantities of water contg. an oil and other floating impurities or waste, comprises passing the impure water in turbulence-free manner through >=1 sepg. vessels arranged in series, adjacent vessels being connected at their bottom zones,a nd carrying out this process at a low velocity so that the oil or floating material separates out and can collect in the upper regions of the sepg. vessels.
