Back-Raking Mechanical Bar Screen for Wastewater Treatment

Back-Raking Mechanical Bar Screen for Wastewater Treatment

Brief Description

The Back-Raking Mechanical Bar Screen is designed for preliminary wastewater treatment to intercept and remove suspended solids, fibrous materials, and other debris. It helps reduce the entry of coarse solids into downstream treatment units.

Product Overview

The Back-Raking Mechanical Bar Screen is suitable for municipal wastewater treatment, industrial wastewater treatment, and other applicable water treatment projects. It uses a mechanical rake mechanism to remove debris retained on the bar rack and lift it to the discharge point for collection and disposal.

The equipment can be configured according to channel dimensions, flow requirements, bar spacing, and site installation conditions to meet different project needs.

Product Parameters

Note: Final specifications should be confirmed against the actual product drawings and technical data.

Working Principle

As wastewater flows through the bar rack, larger solid materials are retained by the bars. During operation, the mechanical rake moves along its designed path to collect and lift the trapped debris to the discharge point, where the screenings are collected for further handling.

Mechanical screening removal helps reduce debris accumulation and minimize its impact on water flow and downstream treatment equipment.

Key Design & Performance Features

1. Mechanical Debris Removal

Uses a mechanical rake mechanism to remove retained screenings and reduce manual cleaning requirements.

2. Practical Structural Design

Designed to suit channel dimensions and project-specific installation requirements.

3. Flexible Configuration

Screen spacing, equipment dimensions, and drive configuration can be selected according to project conditions.

4. Flexible Operation Control 

Operating control options can be configured according to the actual control system.

5. Downstream Equipment Protection 

Helps prevent coarse solids from entering downstream treatment units and reduces the risk of blockage.

Applications

1. Preliminary treatment in municipal wastewater treatment plants

2. Industrial wastewater treatment systems

3. Wastewater pumping stations

4. Water intake and drainage projects, where applicable

5. Other water treatment applications requiring mechanical debris screening
