Polyester Filter Belt for Belt Filter Press

A polyester filter belt is the core component of a belt filter press, responsible for solid-liquid separation in wastewater treatment, mining, food processing, and chemical industries.

Key Features

High Strength and Durability – Made from premium polyester monofilament yarn, the belt resists stretching, abrasion, and chemical wear, ensuring long service life under high mechanical stress.

Excellent Permeability – The precise weave structure allows for efficient water drainage while retaining fine particles, improving filtration performance and cake dryness.

Stable Performance – Maintains consistent filtration under varying temperature and pH conditions, making it suitable for a wide range of sludge types and industrial processes.

Easy Cleaning and Maintenance – Smooth surface minimizes clogging and enables quick belt washing, reducing downtime and maintenance costs.

Customizable Design – Available in different air permeability grades, weave patterns (plain, twill, or satin), and joint types to match specific belt filter press models and applications.
