Product Overview

Step Type Fine Screen is a high-performance mechanical screening solution used for fine solids removal in wastewater treatment. Engineered for both municipal and industrial applications, this screen ensures efficient solid-liquid separation with minimal manual effort. The stepped design enhances solids handling capacity, allowing smooth operation even under variable flow conditions. It is ideal for primary screening in sewage treatment plants and effluent treatment systems.

Working Principle

The Step Type Fine Screen operates by capturing suspended solids on a series of interlocking steps attached to two parallel chains. As the chains rotate, each step carries the solids upward in a stepwise motion while the wastewater flows through the open slots. Once the solids reach the top, they are automatically discharged using a mechanical wiper or scraper system. This process ensures uninterrupted operation, minimal clogging, and effective fine screening with low maintenance.
