WASTE WATER TREATMENT PROCESS FOR PRODUCING HIGH YIELDS OF DRINKING WATER |
摘要 |
<p>A process is disclosed for optimising the treatment of organically and possibly inorganically contaminated waste water, in particular from returnable package rinsing and cleaning installations, preferably the water used for washing returnable bottles before they are re-used. This particularly appropriate multiple stage membrane separation process optimises the effort required, produces a pure water with drinking water quality and optimises the yield of purified water. The invention allows rinsing water to be almost completely recycled as make-up water in subsequent washing and cleaning steps.</p> |
