Applications
The ZG series represents an innovative integration of three key functions: fine screening, residue lifting, and compaction. Suitable for installation in channels or containers, this unit is designed for municipal and industrial wastewater treatment plants to effectively intercept and manage solid waste.

Structure & Working Principle
The drum screen basket, constructed with precisely spaced bars, is engineered to optimize filtration. Wastewater enters from the front of the drum, passes through the screen, and exits through the outlet. Solid waste is retained on the inner surface of the screen.

When the differential water level reaches a preset threshold, a motor-driven rotary rake mechanism activates. The rake cleans the screened material and lifts it to the top of the drum. Most debris discharges by gravity into a collection hopper; adhered residues are removed by an automatic wiper blade. A integrated screw conveyor then lifts, compacts, and dewaters the waste before final discharge.

Key Features

1. High Capture Efficiency: The 35° screen inclination and curved design create a self-baffling effect, trapping even fine particulates smaller than the bar spacing.

2. Self-Cleaning Function: Equipped with integrated spray wash, anti-jamming rakes, and an automatic cleaning blade for continuous operation.

3. Optimized Hydraulics: The cylindrical structure increases effective screening area, reduces head loss, and minimizes upstream solids buildup.

4. Corrosion-Resistant Construction: All wetted parts are manufactured from acid-passivated stainless steel, ensuring longevity in harsh sewage and industrial effluent environments.

5. Space-Saving Integration: Combining screening, conveying, and dewatering into one compact system reduces footprint and downstream handling costs.

6. Low Maintenance Design: Sealed rotational components require minimal lubrication, and the drive unit operates with extended service intervals.
