The working principle of the belt filter press:
the sludge is evenly fed into the mesh belt through the cloth bucket, and runs forward with the filter belt. The free water flows into the water tank through the filter belt under the action of self-weight and removes the free water in the sludge to make the sewage The fluidity of the mud is reduced to prepare for further extrusion. Gravity dewatering is followed by a wedge-shaped pre-pressure dewatering stage, and slight extrusion dewatering ensures that the sludge is smoothly pressed and dewatered. The upper and lower filter belts sandwich the filter cake and repeatedly press and shear around the press roll to remove a large amount of capillary action water so that the filter cake moisture is gradually reduced, thereby achieving dehydration.

Because of the variety of species, when choosing the corresponding filter press, not only the practical type of the filter press itself, but also the cost of using it, and a high-end and suitable filter press will be You save a lot of money. There are many enterprises that purchase filter presses are used in sewage treatment. The capacity of equipment cannot be loaded with sludge, which often causes sludge accumulation. According to environmental protection regulations: sludge with a water content of less than 60% can be used for resource utilization. Therefore, when purchasing a filter press, the primary factor is the moisture content of the sludge treated by the equipment.
What type of filter press should we choose to be suitable for the amount of wastewater we need to process every day. Below we need to choose the filter press according to the calculation of sewage treatment. Commonly used calculation methods include wet sludge volume method, dry sludge volume method and suspended solids method. The wet sludge volume method is relatively accurate, and the data required for calculation is also easy to measure, so it is recommended to use it preferentially.
Wet sludge volume method:
Filter area standard: The filter area of a filter press manufactured according to the national standard is equivalent to a solid volume of 15 L per square.
Before filter press: volume V1 (m3), moisture content of sewage before filter press a (underflow) = 97.5%~99.2% (general experience value). After pressure filtration: volume V2 (m3), sludge moisture content after pressure filtration b (non-washable) = 75%.
Pressure filtration cycle: the number of pressure filtration per day t. Solid content balance method: V1 × (1-a) = V2 × (1-b), and it is found that V2 = V1 × (1-a) / (1-b). Filtration area: S = × V2 / 15t = × V1 × (1-a) / 15t (1-b).
For example: a sewage treatment plant in Luoyang, Henan, the number of pressure filtration times per day t = 1, after treatment (to the sludge concentration tank) to produce a wet sludge volume V1 = 8m3, water content a = 98.0%, assuming daily sludge treatment 1 Second, the filter area of the required filter press = × 8 × (1 ' 98%) / 1 × 15 × (1-75%) = 42.6, according to the calculation, it is recommended to use a filter area of 42.6m2 filter press.
According to the above example, it is necessary to select a filter press with a filter area of 42.6 m2, and an optional G50-80 chamber filter press or an lZZG model DY belt filter press.

Filter presses are an essential piece of equipment in many industries, especially those that require the separation of solids and liquids. A filter press is a mechanical device that is used to filter and separate solids from liquids, typically in large quantities. In this blog post, we will discuss what a filter press is, the Jingjin filter press specifications, the filter press system, and the filter press price.
Tell You What A Filter Press Is?
A filter press is a type of equipment that is used to filter and separate solids from liquids. It consists of a series of plates, each with a filter cloth on one side. The plates are arranged in a stack, and the material to be filtered is pumped into the press. The liquid passes through the filter cloth and is collected in a container, while the solids are retained on the filter cloth.

Specifications Of Jingjin Filter Press
Jingjin is a well-known manufacturer of filter presses, and they offer a range of products to meet the needs of various industries. The Jingjin filter press specifications vary depending on the model, but some of the key features include:
Maintenance easily
High-capacity filtration
Steady and durable construction
High efficient automatic operation
Corrosion-resistant materials
Jingjin filter presses are available in a range of sizes and designs, including overhead beam, sidebar, and membrane designs. They can be customized to meet specific application requirements and have a reputation for reliability and efficiency.
Detail Of Filter Press System
A filter press system includes the filter press itself, as well as other components necessary for filtration, such as pumps, piping, and valves. The filter press system is designed to work together to provide efficient and effective filtration of liquids. Depending on the application, additional equipment may be required, such as sludge dewatering systems or filter aid feed systems.
Planning To Buy filter presses? Please Consider To The Cost
The price of a filter press can vary widely depending on the size, design, and features of the equipment. Generally, smaller filter presses are less expensive than larger ones, and manual operation is less expensive than automatic. Jingjin filter presses are known for their high quality and reliability, and their prices reflect this. However, investing in a high-quality filter press can ultimately save money in the long run by reducing downtime and maintenance costs.
