4. End-to-End Capability: In-house R&D and full manufacturing control ensure stringent quality standards.

Applications
The ZG-Series integrates fine screening, slag lifting, and compression dewatering into a single system. Ideal for municipal and industrial wastewater treatment plants, it effectively intercepts and processes solid waste in channels or containerized installations.

Technical Parameters

Additional Dimensions

• Length (L): 3–9 m

• Width (A): 2.6–9 m

• Motor Power: 1.1–3 kW

Working Principle

1. Screening: Wastewater enters a drum-shaped screen basket; solids are trapped on the bar surface.

2. Cleaning: A rotary toothed rake activates when water level differential triggers cleaning cycles.

3. Discharge: Debris is lifted to the top, scraped into a slag slot, and conveyed to a compression unit for dewatering.

4. Compression: A screw press reduces debris volume before disposal.

Key Features

1. 35° Angled Bar Design: Creates a baffle effect to capture fine particles smaller than bar gaps.

2. Self-Cleaning System: Integrated flushing and anti-clogging mechanisms minimize manual intervention.

3. Optimized Hydraulics: Cylindrical structure increases flow velocity and reduces head loss.

4. Corrosion-Resistant Materials: Pickling-passivated stainless steel or nylon components for longevity.

5. Space-Saving Integration: Combines screening, conveying, and compression in one unit.

6. Low Maintenance: Lubrication-free rotating points and minimal drive unit servicing.

Outline and Installation Chart

Technical Requirements
