PCT No. PCT/CH96/00451 Sec. 371 Date Jun. 11, 1998 Sec. 102(e) Date Jun. 11, 1998 PCT Filed Dec. 19, 1996 PCT Pub. No. WO97/22560 PCT Pub. Date Jun. 26, 1997An installation for the simultaneous separation and removal of fats and oils in waste water, which includes a treatment container chamber for receiving a liquid medium. Out of the treatment container chamber, through a bottom outlet, is an overflow pipe running upwards and which opens outwardly outside of the treatment container chamber as a discharge pipe, so that its inside bottom edge, at the point where it opens outwardly, defines a level of a medium in the treatment container chamber. A support material in the form of a plurality of plastic tubes is wound with lengths of polyester cord colonized with a fat and oil-degrading yeast microorganism Yarrowia lipolytica W1 in the treatment container chamber. A nutrient solution container, with a metering pump for feeding NH4+ into the treatment container chamber, as required, is included as a source of nitrogen for the fat and oil-degrading microorganism, along with a device for supplying the microorganisms with air. Finally, a metering device having a programmable control device, for metering previously separated fat and oil from either a waste water container chamber arranged outside the treatment container chamber and belonging to the overall installation for removing fat and oil, or from a separate fat-separator, to said treatment container chamber, is included. |
