Bolian Filtration -The Application of Vacuum Filter Cloth

In the expansive domains of industrial production and environmental treatment, vacuum filter cloth plays a pivotal role as a filtration medium, with its significance being readily apparent. This article will explore the diverse applications of vacuum filter cloth, beginning with fundamental principles and progressively uncovering its specific uses and value across various industries.

Basic Principles of Vacuum Filter Cloth
As implied by its name, vacuum filter cloth harnesses the negative pressure generated by a vacuum system as its driving force. The liquid to be filtered passes through the cloth layer, while solid particles are retained on the surface or within the fabric. This process enables solid-liquid separation efficiently and effectively.

Application of Vacuum Filter Cloth in Mining Industry

In mining operations, vacuum filter cloth is extensively utilized in ore sorting, tailings treatment, and concentrate dewatering processes. For instance, during gold mining activities-following crushing and grinding-the resultant slurry contains fine gold particles along with impurities. Employing vacuum filter cloth for dewatering not only effectively recovers fine gold but also significantly enhances both the grade and recovery rate of the concentrate.

Vacuum Filter Cloth in Environmental Water Treatment
In the field of water treatment, vacuum filter cloth is mainly used in sludge dewatering in sewage treatment plants, industrial wastewater treatment, and pre-treatment of drinking water.

Fine Filtration in the Chemical Industry
In the chemical industry, especially in the fields of fine chemicals, pharmaceuticals, and biotechnology, there are extremely high requirements for product purity and quality.

Hygienic Filtration in the Food Processing Industry
Hygiene and safety are paramount concerns in the food processing industry. Vacuum filter cloth proves indispensable in applications such as recovering cleaning water from production lines, clarifying fruit juices, and filtering dairy products. Its capacity to provide high filtration accuracy while adhering to food-grade safety standards is invaluable.

Wastewater Treatment in the Textile Dyeing Industry
In the textile and dyeing industry, vacuum filter cloth is essential for treating wastewater, particularly during advanced treatment stages. By filtering out suspended solids and colloidal substances, it facilitates subsequent biological treatment or advanced oxidation processes, contributing to overall water quality improvement.

Bolian's vacuum filter cloth is woven using a double-layer monofilament fabric structure, with a maximum width of up to 4.8 meters. The materials are primarily polypropylene and  polyester, all has widely applicable. The product features a double-layer structure, with one side as the filtration layer and the other as the support layer, interwoven and stacked together. Due to the robust support provided by the backing layer of the filter cloth, the mechanical strength is significantly increased.
