Cost-Effective Wastewater Pre-treatment: Why a Screw Screen is the Smarter Investment

When managing an industrial wastewater project—like our recent installation for a chemical facility in Zibo, Shandong—budget is often the biggest hurdle. If your client needs to reduce both initial capital investment and long-term operational costs, choosing the right screening technology is the first critical decision.

Why Choose a Screw Screen Over Traditional Bar Screens?

In many industrial applications, traditional bar screens require secondary equipment: a conveyor to move the solids and a press to dewater them. For a facility with limited space or a tight budget, this "multi-machine" setup is expensive to buy and maintain.

That is why we recommended the Screw Screen (Screw Screening) for this project.

A Screw Screen is a unique 4-in-1 system that integrates:

1. Filtration: Capturing solids as small as 1mm.

2. Washing: Removing organic matter from the screenings.

3. Transporting: Lifting solids out of the channel via a rotating screw.

4. Compacting: Pressing and dewatering the waste before disposal.

By combining these four functions into one stainless steel unit, the client eliminated the need for separate conveyors and presses. This reduced their total investment significantly.

Project Spotlight: Industrial Wastewater in Zibo, Shandong

This specific case involved a high-flow industrial channel. The goal was to achieve clean, odor-free solids recovery while keeping power consumption low.

Technical Specifications:

l Material: Heavy-duty Stainless Steel

l Channel Dimensions: 600mm wide and 2000mm deep

l Capacity: High-volume flow of 130 tons/hour

l Efficiency: Equipped with a 1.1KW motor, providing high torque with very low energy use.

l Performance: The solids are pressed until they reach nearly 40% dry matter content, which drastically lowers waste disposal fees.

The system was installed at a 35-degree angle, allowing the 3800mm long screw to efficiently lift and dewater the screenings in a single, continuous motion.
