Filter bags are industrial fabric bags used to separate solids and impurities from liquids and gases. The following are some common types of filter bags.
Dust Filter Bags
Dust bags are primary components of baghouse dust collectors. Typically inserted into a hopper-like structure called a pleated chamber, filter bags are used to arrest dust at the source by trapping it within the filter bag. The trapped dust forms a filter cake that improves the filter bag's efficiency by reducing the amount of dust that passes through until the filter bag is full.
Liquid Filter Bags
Liquid filter bags operate under similar principles as dust filter bags but for liquids. They come in various micron ratings and are designed to arrest particles, contaminants, and impurities passing through them. The bags are usually fitted into liquid bag filters, and once they collect the desired contaminants, they are disposed of, and the filter is replaced.
Strainer Filter Bags
Strainer filter bags are used to contain the straining of solids from liquids. They are primarily used to protect pumps and smaller downstream equipment from being damaged by large solids. Strainer filter bags are usually set up in batch processing and are often used to protect the facility's production lines.
Cartridge Filter Bags
Like strainer filter bags, cartridge filter bags are designed to remove contaminants from liquids. However, cartridge bags are designed to filter larger volumes of liquids as they run through the filter bag's cartridges. Filter cartridges are, therefore, perfect when large contaminants are needed to be captured, usually in water treatment facilities.
Hydraulic Filter Bags
Hydraulic filter bags are designed to strain solids from liquids in hydraulic systems. They are usually custom-made to fit specific hydraulic vent lines but work just like any other filter on the production line. Hydraulic filter systems can be automotive, marine, or industrial.
Polyester Filter Bags
Manufacturers make filter bags with polyester fabric to make them durable. With durability being chief among the benefits of filter bags constructed of polyester fabric, the bags can be washed and reused several times while still in use—but not forever, though. The fabric is used to put together filter bags that are utilized by swimming pools, water treatment sectors, and air pollution control facilities.
Diameter:
Generally, the filter bag diameter is between 50 and 400mm. Businesses can choose the right diameter according to the scale and capacity of their filtering system.
Length:
The length of the filter bag usually is around 200 and 2,000mm. Longer filter bags can provide more filtering surfaces and efficiency.
Material:
The materials of filter bags include cotton, polyester, polypropylene, nylon, and more. Different materials have distinct temperature resistance and chemical stability.
Purification accuracy:
Filter bags' precision is usually measured in micron sizes, which can range from 1 to 100 microns. Businesses can choose the appropriate filter bag according to the required filtration accuracy.
Edge treatment:
Some filter bags adopt edge treatments, like welded edges and sewn edges, which can reduce bag-shaking and wear inside the cages.
Regular cleaning:
Using a soft brush or vacuum to clean the exterior of the filter bag. It can prevent the ingress of foreign objects and keep the bag clean.
Periodic washing:
According to usage frequency and working environment, regularly wash the filter bags using mild detergents and water. Ensure them are thoroughly dried before reuse.
Inspection and repair:
Regularly inspect filter bags. Check if there are any damages, holes, or stuck particles. Repair or replace them immediately if finding any problems.
Dust removal:
Using an air compressor to blow out the dust inside the filter bags. It helps to maintain the bag's air permeability and filtering efficiency.
Paying attention to storage:
When not using the filter bags, store them in clean, dry, and ventilated places. Avoid exposure to sunlight or humidity for long periods.
Beverage industries around the world rely on filter bags to give their clients a perfect cup of tea or coffee. The bag aids in the extraction of flavors and composition of the drink when in contact with hot water. In the medical field, pharmaceutical filter bags are employed in the production of safe and effective medications. They assist in the segregation of active ingredients, ensuring that impurities do not enter the final product. Filter bags with activated carbon are widely used in the air purification industry. Such filter bags are employed in air purifiers, extractor fans, and hood filters to clean and decontaminate indoor air. They attract, trap, and neutralize airborne contaminants, volatile organic compounds (VOCs), odors, and toxins, resulting in improved indoor air quality. With growing environmental concerns, industries ranging from manufacturing to food processing are adopting filter bags in waste management. Filter bags are critical components of bag filters, which are widely used to collect particulate matter from flue gases in filter bag dust collectors.
The filter bag has numerous applications in food processing. In the juice manufacturing process, for example, filter bags are used to clarify freshly squeezed juice. The filter bags are able to separate the pulp from the clear liquid. The end product is a juice that meets consumer expectations. Yeast is another example of filter usage in the food processing industry. When brewing beer, filter bags are used to hold yeast throughout fermentation. When the process is over, the filter is removed, and the beer is free of excess yeast. The result is a crystal-clear product that may be used without further filtration.
Filter bags aren't just for liquids; they're also used in the culinary world to make flavorful infusions. Restaurants, catering services, and culinary workshops can utilize them to extract flavors from herbs, spices, and botanicals, which are then added to broths, sauces, marinades, and pickles.
Cosmetic companies can use filter bags to process herbal extracts, essential oils, or plant infusions for their products. When manufacturing such products, the company can conveniently use filter bags for maceration or extraction processes. The final result will be a product with aromatic and herbal properties.
Mobile filter bags are widely sought after in the sample analysis scenario. They are used in conjunction with gas chromatographs (GC) or high-performance liquid chromatographs (HPLC) for the analysis of samples in the environment, food, and clinical research, among others. Filter bags for sampling allow for the concentration and capture of specific compounds or contaminants from different matrices for subsequent analysis and quantification.
With so many choices of industrial filter bags on the market, it's important to know what buying consumers are thinking and what their preferences will be.
Many filter bag purchases will be based on their practical uses, such as what kind of filter they will install, what kind of medium they will use, and perhaps what kind of pH value and temperature the bags need to withstand. Also, will the filter need to be customized in any other way, such as size, construction, or color?
Some business buyers may be more focused on the number of purchases they need to make per year and will be looking for strong, durable bags that can withstand repeated use rather than single-use. They may also be looking for something that can be easily laundered and reused, thereby reducing costs and helping the environment.
Food-grade filter bags are in high demand among food and beverage business buyers, as are pharmaceutical filter bags for the health and pharmaceutical industry, so these niches could be a focus if one is a seller.
