Does stopping operation for eight days along with adding flour work?
In industrial wastewater treatment plants, it is common for many companies to encounter situations where no production wastewater is generated due to holidays or temporary shutdowns. In such cases, domestic sewage can be added to the biochemical tank, or river water can be pumped in, along with a paste made from dry flour that has been cooked, in order to maintain the growth and reproduction of microorganisms. In the biochemical tank, 5–10 kilograms of dry flour can be added per 100 cubic meters of volume, or waste alcohol can be added in proportion; aeration should take place for 4–8 hours per day.
