Paper Belt / Band Filter For Filtration Of Process Fluids
Product Overview
The Paper Band Filter is an efficient and economical filtration system designed for the removal of solid impurities from wastewater, cutting fluids, and industrial process liquids. It is widely used in metalworking, surface treatment, and wastewater treatment plants to ensure clean and stable liquid circulation.

Working Principle
The liquid containing suspended solids flows through a filter paper mounted on a conveyor belt. The impurities are trapped on the filter paper surface, and as the clogging increases, the liquid level rises. The system automatically advances the paper band, replacing the clogged section with fresh filter paper, ensuring continuous filtration.
