Bag filters can offer a very robust filtration. Their filtration removal ranges from 1-200µ. Water flow capacity is dependent on the size of the bag used. The larger the bag, the higher the acceptable flow rate. Not all filter bags are the same. Special coatings and specific pore sizes are used to remove certain chemicals from permeate.

Bag filtration is a very effective way of purifying water and is capable of managing very high volumes of water. They are one of the most cost effective ways of filtering water and are capable of withstanding exposure to a wide range of process conditions and substances making them a good all rounder. There is little else available on the market that is capable of withstanding high flow rates whilst remaining low cost. There are more robust filtration methods available on the market but none that will complete with the flow rates that bag filtration can withstand and none that are as cost effective.
Bag filtration works by the method of micro-filtration. The permeate passes through the bags and the contaminants become lodged within or on the surface of the bag filter as the smaller water particles freely pass through.
Nylon bag filters are double stitched nylon fibre and are cross-stitched to ensure that larger particulate cannot pass through. Polyester or polypropylene bag filters are heat bonded to ensure appropriate rigidity of the pores. There is a wide range of micron sizes available so you can be sure there is one to suit your intended application.
