METHOD FOR PROCESSING WASTE WATER |
摘要 |
An apparatus and method for treatment of food process waste water, comprising a tank for receiving a food process waste water influent via an influent pump and discharging a treated food process waste water effluent via an effluent pump; a screen decanter disposed in the tank; the screen having a porosity of about 50 micrometers; and a timer operationally connected to the floating decanter and the effluent pump. Solids are settled from the waste water and drawn off through the tank bottom after a supernatant fluid is drawn off through the floating decanter. The supernatant fluid is passed through a filtration and membrane water purification apparatus to generate purified water. |

1. A method for treating an effluent stream of food process waste water generated by food processing steps, comprising the steps of:
a) providing a tank for receiving and treating said effluent stream; b) receiving a volume of said food process waste water in said tank; c) allowing said received volume of food process waste water to stand in said tank without agitation for a predetermined period of time, to cause gravitational settling and separation of suspended solids in said food process waste water into a settled solids fraction and a supernatant fraction; d) drawing off said supernatant fraction after said predetermined period of time through a decanter selected from the group consisting of screen decanter and non-screen decanter; e) drawing off said settled solids fraction from a lower surface of said settled solids fraction; and f) passing said supernatant fraction through a filtration and membrane water purification apparatus to generate purified water. |
