Rotary Sludge Thickening Scraper for Square High Density Sedimentation Tank
Brief Description
GMG Sludge Thickening Scraper is core equipment for square high density sedimentation tank clarification system. It achieves continuous sludge collection and in-tank thickening. Continuous operation of the scraper assembly facilitates sludge consolidation. Part of the thickened sludge is recirculated to the upstream reaction zone to maintain the high sludge concentration needed for homogeneous flocculation. Featuring high processing capacity, low moisture content of discharged sludge and compact layout, the unit is mounted on the top of sedimentation tank for convenient inspection. It efficiently collects settled sludge to stabilize clarification performance. Widely used in raw water purification, municipal wastewater treatment, industrial wastewater treatment and sludge treatment projects.
Product Overview
GMG series sludge thickening scraper is specially engineered for square high density sedimentation tanks. The whole machine mainly comprises drive unit, central drive shaft, connection frame, pull rods and sludge thickening assembly. The standard blade lifting height is 150 mm. Available specifications suit square tanks ranging from 6m×6m to 16m×16m. Wetted parts can be manufactured from carbon steel or stainless steel upon raw water quality requirements. Auxiliaries including electrical control cabinet can be supplied optionally as requested.
Working Principle
The top-mounted driving unit transmits torque downwards via the main shaft to drive the connecting frame and scraper assembly to perform rotary movement. Settled sludge on the tank bottom is continuously pushed to the central sludge hopper by scraping components. The integrated thickening assembly achieves in-tank sludge consolidation. Sludge collected in the central hopper is split into two streams: part of the thickened sludge is pumped back to the upstream flocculation zone to sustain the required sludge concentration for flocculation, and the surplus sludge is discharged out of the system. Clear supernatant rises and overflows as final clarified effluent.

Key Design & Performance Features
1. High surface loading rate and compact layout. With sludge recirculation and polymer dosing, surface loading can reach 15~25m³/(m²·h).
2. High concentration of discharged sludge. With sludge recirculation and flocculant addition, sludge concentration can achieve 20~50g/L.
3. Strong anti-interference capacity, less sensitive to fluctuation of influent water quality.
4. Low suspended solids in final effluent, stable clarification performance.
5. Top-mounted drive structure; inspection and routine maintenance can be completed above the water surface conveniently.
Applications
Designed for installation inside square high-density sedimentation tanks of raw water treatment plants, municipal wastewater treatment stations and various industrial wastewater treatment facilities. Widely applied to solid-liquid separation, flocculation clarification and sludge thickening processes for water supply, domestic sewage and industrial wastewater treatment projects.
