Bag filtration systems ZhongTing remove sand, salt and large solid particulate from water. This is an economical alternative to cartridge or membrane filtration.

Conventional sewn felt and seamless bags are available in standard industry sizing to fit filter housings. Felt bags are depth filters with high debris holding capacity.

Mesh bags offer surface filtration for food and beverage production, chemical processing and other liquid applications. Welded seams eliminate needle holes and guarantee no contaminant bypass during operation.
High Flow Capacity

In many applications, a high flow rate is required. For these types of situations, bag filtration can offer the best solution for your process. Bag filters have a very large surface area that allows liquid to pass easily through the filter. This high surface area also means that a large amount of contaminants can be captured in the same time.

The primary job of a bag filter system is to reduce silt, sand and other types of sediment from your water. This can improve product quality and safety, reduce downtime due to clogs or pressure drops, and limit worker exposure. These filters are available in a range of micron ratings, with smaller numbers indicating finer particle removal. They are not designed to remove bacteria or chemicals, however, so additional filter systems may be needed for that purpose.

Wastewater treatment is a necessary step in any industrial process. It takes wastewater from homes, businesses and factories and makes it clean enough to return to the environment. This used water contains many things, including human waste, food scraps and oils, soaps, detergents and other chemicals. It can then be reused for other purposes, or it can be sent to sewage treatment plants and then returned to nature.

Bag filters are an excellent choice for filtering industrial wastewater, and they have a low maintenance cost. They are also a great option when a higher level of purification is not required. Cartridge or membrane filtration can provide better results, but they require more frequent changes and can be expensive.

Coagulants are chemical solutions used in many wastewater and dewatering sludge treatment processes, such as removing colloidal solids from water, demulsifying oil emulsions, and paint detackification. These solutions work by electrostatically charging oppositely charged particles or microflocs to clump together into larger aggregates that are easily separated from the water.

Filter bags can be used in conjunction with coagulation and flotation processes to improve sludge treatment performance and reduce the amount of energy used in the process. They are available in a wide variety of sizes and materials, from simple mesh bags to high-performance felt sewn seam bags.
Low Maintenance

The low maintenance that liquid filter bags offer reduces downtime and allows for a continuous flow of filtered liquid, which helps to increase productivity. The filtration surface area of these bags is larger than other filter methods, which allows for a higher level of contaminant removal. This translates to higher product quality, reduced downtime, and lower cost. Additionally, the use of these filters is environmentally friendly, making it a popular choice for a wide variety of industries.

The process of manufacturing liquid filter bags begins with selecting high-quality raw materials that are characterized by their strength, durability, and porosity. Once these raw materials are selected, they are cut into the proper size and shape using advanced cutting equipment. Next, the raw materials are sewn together and inserted into a support basket that provides structural support. Finally, the bags are tested to ensure that they meet the manufacturer’s specifications.

When a liquid passes through the bag, contaminants and particles that are larger than the filter’s micron rating will be trapped on the outside of the bag. As the liquid continues to pass through the bag, smaller contaminants will be trapped in the inside of the bag. This process continues until the liquid is free of all contaminant particles and meets stringent quality standards.

Liquid filter bags are manufactured from a wide variety of materials, including polyester, polypropylene, and nylon. These materials are chosen for their strength, durability, and temperature resistance. They also offer a range of pore sizes to suit different liquids and applications. The material of a liquid filter bag can also be treated with a number of finishing processes, such as dyeing, lamination, and teflon coating.

These finishing processes can improve the filter’s appearance, its resistance to moisture and other substances, and its longevity. For example, dyeing can add color to the filter, while lamination can enhance its strength, air permeability, and porosity. Teflon coating can protect the filter from water and other liquids, while hydrophobic coating repels water and oil, which can improve the bag’s lifespan. These finishing processes can also be used to create a custom filter for your specific application.
Economical

Bag filters are a great option for smaller applications or systems that need to minimize waste. They are essentially a container made of porous material in the shape of an elongated bag, which allows the wastewater to flow into it and the impurities to be caught on its surface. Depending on your system’s needs, you can use bags with different-sized pores to catch various types of particles. These filters can be disposed of in compliance with environmental regulations, and they are often cheaper than cartridges.

Felt filter bags are available with either a sewn or welded seam, and they can be used for both depth and surface media applications. They offer an economical way to remove particulate from liquid streams ranging in size from 1 micron to 2000 micron nominal. They are a versatile, durable and inexpensive alternative to woven fiberglass or spun-bonded cellulose. One standard bag can replace up to nine cartridges, resulting in cost savings or increased service life. Felt filter bags can be used in a wide variety of industries, including chemical industry, waterandwastewater, food and beverages, pharmaceuticals, paints, inks and coatings.
