In Which Fields is the Duplex Bag Filter Used

Bag Filter April 27, 2025 Duplex Bag Filter Housing

The Duplex Bag Filter, also known as the duplex switching filter, is composed of two stainless steel bag filters arranged in parallel or series. The two filters can be used alternately or operated simultaneously.

Working Principle
The suspension is pumped into each sealed filter chamber. Under working pressure, the filtrate is discharged through the outlet, while the filter residue remains inside the frame, forming a filter cake to achieve solid-liquid separation. The liquid enters the filter housing through a side inlet pipe, passes through the filter bag installed inside a reinforced support basket, and then through the bag of the required filtration grade to produce qualified filtrate, with impurity particles trapped inside the filter bag.

Application Fields

Industry
In industrial processes, reused cooling water can be simply filtered after multiple uses to reduce costs.
Steel and Petroleum Industries
Used for filtration of circulating water in the steel and petroleum industries.
Daily Life
Used for filtration of domestic water and some process water.
Aquaculture
In aquaculture centers, where high water quality is required, the duplex bag filter can be used to purify seawater for marine products or to filter freshwater for freshwater farming.
