High-Efficiency Tube Settling Sedimentation Tank with Integrated Sludge Recirculation and Automatic Sludge Discharge

High-Efficiency Tube Settling Sedimentation Tank with Integrated Sludge Recirculation and Automatic Sludge Discharge

Brief Description

The High Efficiency Sedimentation Tank integrates mixing-flocculation, sludge recirculation, tube settling and sludge thickening into one unit. Equipped with an internal sludge recirculation process, it enhances floc formation and improves pollutant removal efficiency. Featuring an integrated structure with less civil construction work, it is especially suitable for projects requiring advanced phosphorus removal and strict control of suspended solids.

Product Overview

The complete unit integrates a rapid mixing zone, flocculation reaction zone, sludge recirculation system, tube settling zone and bottom sludge thickening zone. It is equipped with stirring mechanisms, thickening sludge scrapers, automatic control pipelines and an electric control cabinet. The whole flocculation reaction assembly is built inside the equipment, which can independently complete the full sedimentation process after wastewater inflow. Customization on material and treatment capacity is available.

Working Principles

1. Wastewater flows into the built-in mixing and flocculation zone, where dosed chemicals fully contact with recirculated thickened sludge to form dense flocs.

2. Flocs enter the tube settling zone for solid-liquid separation.

3. Part of the settled sludge is recirculated to the front flocculation zone, while residual sludge is thickened at the bottom and discharged periodically.

4. Clean water rises to the collection trough and flows by gravity to subsequent treatment processes.

Product Parameters

Key Design & Performance Features

1. Integrated Process: Flocculation, sludge recirculation, sedimentation and thickening are combined in one unit, eliminating the need for separate front-end reaction tanks.

2. Enhanced Treatment Performance: Contact flocculation via sludge recirculation effectively removes colloidal pollutants and delivers excellent phosphorus removal capacity.

3. High Loading & Compact Footprint: High surface loading rate, requiring smaller land area compared with conventional sedimentation tanks under equal water flow.

4. Stable Effluent Quality: Strong resistance to hydraulic and organic shocks, delivering stable suspended solids in outlet water.

5. High Degree of Automation: Linked automatic control for all procedures to reduce manual attendance.

Applications

1. Advanced Treatment of Municipal Sewage: Upgrading & reconstruction of urban wastewater treatment plants, advanced purification after secondary sedimentation.

2. Industrial Park Comprehensive Wastewater: Phosphorus removal and advanced sedimentation for centralized wastewater treatment stations in industrial parks.

3. Waterworks: Purification of raw water with low temperature and low turbidity.

4. Wastewater Upgrading Projects: Capacity expansion and upgrading of existing wastewater treatment systems.
