Sieve Bend Screen for Orange Peel Wastewater Separation in Egypt

Our client is a fruit processing plant in Egypt. They required a sieve bend screen for their wastewater stream, which contains solid orange peel and light liquid oil (uncoagulated in water). A requirement was that the oil-containing water must not be discharged together with the solid waste.

Technical Requirements

Screen slot size: 0.7 mm
Capacity: 25 m³/h

Client Questions Addressed

Is the screen replaceable? Yes. The screen is a wear part and is designed for easy replacement to simplify maintenance.
Cleaning method — manual or automatic? Automatic. A screw or independent scraper/brush continuously scrapes the back of the screen during movement, combined with high-pressure spray water to keep the screen open and unobstructed.
Working principle — gravity or pressure? Primarily gravity, supplemented by mechanical force (gravity filtration, mechanical conveying, and pressing).
Is it CIP-compatible? Yes, it is compatible with CIP cleaning.
Can it handle multiple types of liquids? Yes, provided the physical properties are compatible, it can handle multiple types of water-based liquid mixtures.
Does it come with sensors or level indicators? No.

Scope of Supply

Main equipment (press, automatic screen cleaning machine) — 1 set
Automatic electric control box — 1 set
Water level probe — 1 set
Flexible hose

How It Works and Key Advantages

The equipment first separates solids from the liquid through the screen, then further reduces the moisture content of the solids via screw pressing, making the waste easier to handle. A cover plate is fitted to prevent material from splashing out.
This design directly addresses the client's key concern: the solid orange peel is separated and pressed out as solid waste, while the oil-containing water passes through the screen and is handled separately — ensuring the oily water is not discharged together with the waste.
