5 Things a Beginner Needs to Know About Bag Filters

by Kristen White Blogger When you have to order bag filter for liquid filtration, there are some things you need to be aware of before you make that order otherwise you may end up with a bag filter that cannot perform the tasks you intend it to.

Usually, if it is a replacement filter, it should be easy to order bag filter for liquid filtration because you simply get the same type as the one you are replacing, but not all filtration systems come with the kind of filter you need so this information may be vital for you. While going about it you can also explore the pressure vessel catalogue for effectively dealing with liquids.


There are Different Materials
Bag filters will have different types of material depending on what kind of solid waste you will be trying to trap in there. The material used can determine the type of waste as well as the size. The great thing about bag filter materials though is that they are reasonably priced. This is why low-cost filtering projects will prefer bag filters.

They can be Used in Different Applications

Because of the different materials that can be used, they can also be used in various applications. One of the common applications is in the purification of water. In industries, bag filters can be used to purify industrial wastewater as well as water to be used in the industrial process. Brewing companies can use bag filters to trap proteins that will influence fermentation speed. They also help to trap any contaminants in the final brew just before bottling.

Bag Filters can be Combined

Some liquids may need extra filtration and just one filter bag may not be sufficient. In the filtration of oil, a combination of bags is used to create different layers. Polypropylene is a common filter bag material used to remove oil from water. Some industries can also use multi-layered bags in the final filtration process to trap fine particles.

External Factors Affect Performance

You might think the quality of your filter bag is questionable, but sometimes it is because you did not take into consideration external factors. For example, not all materials can withstand high or low temperatures, also, the chemical composition of the liquid can play a part in its performance. When you choose the media that the bag is made from, ensure that it can withstand the environment it will be in or else you will either have to replace it very soon or it will fail to trap particles the way you expect it to.

Magnetic Inserts can Extend the Bag’s Life

Ferrous buildup is a big concern in most bag filters since the build-up can reduce the effectiveness of the filter. Modern filter systems have magnetic bars that can prevent too much deposit from remaining in the bag. If the magnetic bars are not used, you will find that you have to replace filter bags more often.
If you are new to filter bags, this information should help you have a fair idea of what to look for when you order a replacement. There's much more you can learn about this important component of a liquid filtering system as you use it, you will learn more.
