The liquid filter bag is a replaceable filter element for bag-type filters. It mainly achieves solid-liquid separation and liquid purification by the retention and adsorption effects of the fiber filter material, leaving the solid particles in the bag while retaining the liquid. The liquid filter bags produced by Xiaohua Environmental Protection cover various materials such as non-woven fabric, PP, PE, nylon, wire mesh, stainless steel, oil-absorbing, high-temperature, PTFE, etc.

Common types of liquid filter bags

PP polypropylene filter bag: resistant to acid and alkali, high cost performance, suitable for most water-based liquids, the heat-melt welding type can reduce the risk of side seam leakage.

PET polyester filter bag: wear-resistant, high-temperature resistant, suitable for media containing particles and oil, the tensile strength is usually better than that of PP filter bags.

Nylon filter bag: good elasticity, reusable, mostly used for high-viscosity liquids, occasions requiring repeated cleaning or coarse filtration or pre-filtration.

Stainless steel filter bag: metal material, high-temperature and high-pressure resistant, washable and reusable, preferred for food and beverage, high-temperature and high-pressure conditions, used for food, select the corresponding material grade according to compliance requirements.

Usually used in conjunction with bag-type filters, some working conditions require the addition of support net baskets.

Xiaohua Environmental Protection focuses on the production and supply of filter bags, pressure filter bags, and filter nets. The liquid filter bags can be customized in terms of material, filtration accuracy, and size according to customer requirements, and are suitable for various bag-type filters; at the same time, it provides pressure filter bags (plate and frame filter bag), industrial filter net products to meet the requirements of solid-liquid separation filtration.

Typical application scenarios

Chemical and petrochemical: resins, solvents, coatings, inks, oil products, catalyst recovery, some working conditions require specific materials and accuracy.

Water treatment: industrial wastewater, circulating water, cooling water, part of the security filtration links in pure water production.

Food and beverage: edible oil, wine, juice, syrup, drinking water purification.

Pharmaceutical and electronics: drug liquid, injection water, ultra-pure water, photolithography resin and chemical reagent filtration, select the corresponding material and accuracy according to compliance requirements.

Automobile and metal processing: electrophoretic paint, topcoat, cutting fluid, grinding fluid, electroplating fluid.
