The pre-filtered wastewater then flows through the feed pipe... The wastewater, after preliminary filtration, is transported back to the first treatment tank 10 through the feed pipe 22. The wastewater then flows into the area of ​​the second guide plate 26 through the guide channel 25. The design of the second guide plate 26 helps the wastewater flow to the lower second filter plate 27.
