Purification and Utilization of Waste Water of Potato Industry by Means of Biological Clarification Plants. The importance of waste water pre‐clearing in potato starch industry by means of a hig‐grade separation of fruit water has been examined in both model and semi‐technological scale. Observing the recirculation principle better economical as well as technical possibilities for biological purification of starch waste waters have been demonstrated by these investigations.1 Starch waste waters which are extensively freed of fruit water can be profitable purified in fresh state as well as after storing in collection tanks in biological clarification plants. 2 Potato starch waste waters can be purified without difficulty in public clarification plants together with domestic waste waters. 3 By their contents of nitrogenic matter and P 2 O 5 potato starch waste waters support the biological process in such waste waters, which are poor of these activating substances, i.e. waste waters of wood processing industry.
