Bag Filters for Water Filtration
One of the most important parts of a water filtration system is the filter; industrial bag filters work much the same way a coffee filter works. The filter is made of a porous material that allows the water to flow through the filter but small enough to capture solids and particulates. Industrial bag filters are recommended for medium to fast water flow rates because they trap the solids while allowing for a rapid flow rate.
All Water Systems offers a large range of industrial bag filters to fit most filtration systems and meet most application requirements. Bag filters vary by material, construction, and most importantly, the filtration size usually designated in microns. We offer housing units to hold the bag filters in place during filtration in both carbon steel and stainless steel, and we recommend stainless steel because it won't corrode or rust like regular carbon steel housing units.
Our high performance filter bags feature durable materials and strong seams to ensure long term usage without the problems of separation or breakage.
Operation
Unfiltered fluid enters the housing and is distributed evenly around the filter bags. Filtration takes place from inside to outside. Solids are collected on the inside of filter bag for easy removal. The filtered fluid then exits through the outlet pipe.
The sizes of these pores are between the 1-50 micron.
The capacity depends on the surface area from the bags. Bigger systems can clean up to more than 500 m3 /h (multi bag filters)
There are special bags for various chemicals.
Engineering
The liquid flows from the top of the filter house (manufactured in either stainless or epoxy coated carbon steel) and is distributed equally amongst the bags. The liquid comes out at the bottom leaving the dirt behind.
Since the bag is locked in at the top of the vessel all the dirt is trapped inside the bag. The filter vessel never requires cleaning after use.
Bag filters systems are applied is various industries solutions. Treated liquids include: milk products, paint, lime, beer etc.
It can also help you with replacement from various filter bags.
01.Small probability for side-bag leakage , which effectively guarantee the filtering quality.
02.Bag type filter can bear greater working pressure, it is of small pressure loss,low operation cost and obvious energy saving .
03.Accuracy of filtration bag increased continuously, it could reach 0.5 μm at most.
04.Bag type filter large handling capacity, small volume, containing a large quantity of pollutants.
05.Based on the working principle and structure of Bag type filtering system,which is convenient to replace the filter bag and without cleaning,and time saving and labor saving.
06.Filtration bag could be use repeated after cleaning to save cost.
07.bag filter application scope is broad, with flexible operation and multiple installation .
