Bag Filter System
- ROTATING BIOLOGICAL CONTACTOR (RBC) SYSTEMS
A Bag Filter System is one of the most efficient and economical methods for removing suspended solids, dust, and fine particles from liquids or gases. It is widely used in water treatment, chemical processing, food & beverages, pharmaceuticals, and various industrial applications where clean output is essential.
- How It Works
The system consists of a housing and filter bags made of high-quality fabric or mesh. As the liquid or gas passes through the bag, contaminants are trapped on the inner surface, while clean fluid exits. Filter bags can be easily replaced, making the system cost-effective and simple to maintain.
