Observe through the observation window. After the sediment sinks, open the valve of the water outlet 16 to discharge the sediment first, and then discharge the treated wastewater. At the same time, open the valve on the oil outlet 17 to discharge the collected oil phase. If there are too many filtrate on the filter plate 8, open the box door to clean it.
