IMPROVEMENT OF WASTE-WATER ANALYSIS AND W ASTE-WATER TRANSPORTATION FOR FAT REFINING INDUSTRIES, IN ORDER TO AVOID UNNECESSARY INVESTMENT AND OPERATING COSTS IN FUTURE SEWAGE-TREATMENT PLANTS

In connection with the water resources policy act, the 4th waste water administration rule for edible fat and oil refinement has been intens ified. This will make further investments in sewage treatment plants n ecessary. The processing and cooling water, the storm water and the mu nicipal water of fat refineries have to be examined more detailed, bec ause only a careful separation of the waste water flows makes a precis e treatment with optimal methods possible. Consequently, the design of the process units can be based on smaller design factors, resulting i n lower investment and running costs of those plants. However, this re quires exact waste water analysis and quantity seizing, which have to be made at the very beginning of waste water occurrence. The realizati on of internal measures, necessary to avoid waste water can also be pl anned, judged and optimized in cooperation with production engineers o n the basis of these analyses.
