Inward Water Drum Filter
The TPI type inward water drum filter is one of the pretreatment solid separating devices used for small and medium wastewater treatment plants, and a device which can remove solid suspended matter continuously and effectively. In some wastewater treatment, 30% to 60% of the organic and inorganic solid suspended matters will be removed after filtered, which will reduce the subsequent workload greatly.
Working principle
The AC variable speed motor drives the grid body through the reducer, and the sewage passes through the inlet valve to the inlet tank, and rises to the filtered water level line through the buffered uniform box partition. The clean water enters the bottom of the cylinder through the gap of the grid and is discharged outward, and the grid is cleaned. Impurities larger than the grid gap and fibrous organic matter are blocked by the grid and rotated to the other side of the grid barrel. Slag is discharged to the slag funnel through the unloader, and the filtered sewage flows to the outlet tank and is discharged through the drain port.
Main Features
1. Simple structure, high reliability.
2. Compact structure, small covering area,
3. Wedge wire wrapped drum for excellent hydraulic performance.
