Water treatment is any process of improving the quality of water to make it suitable for a specific end use. Bag filter treatment refers to placing one or more bag filters inside a bag filter housing to remove suspended solids from the water.

The specific bag filter varies according to the industry in which it is used. This method of filtration is versatile and economical for quickly filtering large volumes of water. How we achieve optimal water treatment with bag filters? This article will reveal that to you.

What are bag filters?

Bag filtration is a very effective method of water purification, capable of treating very large volumes of water. They are one of the most cost-effective methods of water filtration and are able to withstand a variety of process conditions and substances, making them a great jack-of-all-trades.

Bag filters remove everything from sediment in water to other solids to some forms of liquid. Because of their superior capacity, high flow rate, and ease of replacement, bag filter systems are the first choice for water filtration.

How Bag Filters Work?

Bag filters operate on the principle of microfiltration. In the bag, the liquid is purified through small permeable pores. Large amounts of water can be filtered using a bag filter. These pores vary in size from 1 to 200 microns. The capacity is determined by the surface area of the bag.

Bag filters as the name suggests – bags are inserted into the filter housing of water system to filter out sediments. Each bag is made of a grid of very fine holes; the size of the holes depends on the type of contaminants in the water.

These suspended solids in the water treatment system will not be able to pass through the small holes in the bag filter and will become trapped within the filter itself, while the clean water will keep going.

Benefits of bag water filter treatment

Few other products on the market can withstand high flow rates while keeping low cost. Although there are more powerful filtration methods on the market, none of them can achieve the flow rates that bag filters can withstand, nor are they cost-effective.


Bag filter water treatment has several significant advantages. These include:

  • Filtering large volumes of water at high flow rates
  • High dirt holding capacity
  • Withstanding a variety of conditions
  • easy to install and replace
  • One of the most cost-effective methods

Disadvantages of bag water filter treatment

It is worth noting that bag filters cannot remove fine particles, bacteria or chemicals in water treatment.(If small particles, bacteria, or chemicals are not an issue in your water, then disregard this point). Cartridge or membrane filtration provides more precise results, meaning it has the ability to remove fine particles, bacteria or chemicals. However, elements and membranes are more expensive, so it is important to balance end goals with budget.

Can bag filters be reused?

Bag filters have a long service life. You rarely need to change bag filters compared to cartridge filters, and you can easily remove and wash them whenever the bag storage is full.


If you don’t need to treat a large amount of water at once, bag filters may be the more economical option – and you can also expect to reduce waste and disposal costs, since many bag filters can be cleaned and reused rather than discarded altogether.

The applications of the bag filter water treatment

Bag filtration is a versatile and cost-effective method for filtering large volumes of water at high flow rates. Bag filter treatment is ideal for commercial, industrial and municipal water filtration applications, these high capacity systems can treat 90 – 2,400 gallons of water per minute, the filters are very suitable for reducing silt, sand, dirt and other types of deposits in water. Such applications include:

  • Agriculture
  • Pre-filtration
  • Brewing
  • Non-critical cleaning of a final product
  • Removal of coarse particles which could potentially damage your equipment
  • Removal of challenging pollutants from a liquid stream
  • Groundwater
  • Cooling water
  • Industrial process water
  • Wastewater

water treatment

Bag filters are commonly used in various industries for water filtration purposes. These filters are designed to remove impurities from water by collecting them in bags made of porous material. Bag filters are used in applications such as drinking water treatment, irrigation and raw water treatment.


Bag filter water treatment is an effective way of reducing particulates in large volumes of water at high flow rates. For such large volumes of water, other filtration ways are not cost-effective. Bag filters are an excellent choice for industrial applications, brewing, pre-filtration, and more.
