A chamber filter press is a widely utilized filtration system in various industries for effective solid-liquid separation. It is particularly popular in wastewater treatment plants, mining operations, chemical industries, and food processing facilities. This system forces the liquid to pass through the filter cloth while retaining solid particles within the chambers.

The fundamental structure of a chamber filter press consists of a series of filter plates with filter cloths, arranged alternately with solid plates. Depending on the application and the nature of the material being filtered, these plates are typically made from materials such as polypropylene, cast iron, or stainless steel. Each plate features a central cavity or chamber where solids accumulate during the filtration process.

What is the working principle of chamber filter press?

1. Feeding stage: First, use a pump to send the mixture to be treated into the chamber filter press. This mixture usually contains solid particles suspended in a liquid.
2. Filtration stage: The feed liquid enters the chamber between the filter plates through the plate’s feed pipe. Filter cloth covers the filter plates to create a filtering area. As the feed liquid passes through the filter cloth, the cloth traps the solid particles, forming a layer of solid residue inside the chamber.
3. Pressure stage: Once the filter chamber fills with the solid residue layer, the filter press starts applying pressure. This is usually done via a hydraulic system or a mechanical pressure device. The pressure forces the liquid in the chamber to go through the filter cloth, while the solid particles stay on the cloth, building up the solid residue.
4. Discharge stage: After applying enough pressure, the filtrate flows out through the filter cloth, but the solid residue stays in the filter chamber.
5. Solid collection: The solid residue keeps piling up in the filter chamber until it’s time for cleaning. If needed, the operator can open the filter press and take the solid residue out of the chamber.

Advantages of Jingjin Chamber Filter Press

1. High Filtration Efficiency: It uses advanced filtration technologies. By aligning filter cloths precisely and optimizing plate design, it gets efficient and good filtration results.
2. Robust and Durable Construction: The company makes filter plates from high-strength polypropylene or other materials that resist corrosion. This ensures the plates last a long time.
3. Excellent Sealing Performance: It has reliable sealing systems. These systems stop leaks and keep the pressure steady during the whole filtration process.
4. User-Friendly Operation: Automated or semi-automated control systems make it easy to operate. They also reduce the need for people to do the work by hand.
5. Wide Range of Applications: You can customize the filter presses. This way, they fit specific process needs.

Filtration Principle

1. Filtration: A chamber filter press uses hydraulic or mechanical pressure on the slurry. This pressure forces the liquid to go through the filter cloth while keeping solid particles inside the chambers.
2. Cake Formation: When liquid passes through the filter cloth, a layer of solid particles builds up on the cloth’s surface inside each chamber. This layer is called the filter cake.
3. Filtrate Collection: The liquid part, or filtrate, goes through the filter cloth and drains into a collection system or channel.
4. Cloth Cleaning: After a while, solids can clog the filter cloth and slow down filtration. You need to clean or replace the filter cloth regularly to keep it working well.

Applications of Chamber Filter Press

1. Wastewater Treatment: People widely use it in municipal and industrial wastewater treatment plants. It shrinks the volume of sludge for disposal and makes water cleaner.
2. Mining and Minerals: In the mining industry, it dewaters mining slurries and recovers valuable minerals. It also helps with handling and getting rid of solid waste and allows for the recovery of water and minerals.
3. Chemical Industry: It improves product quality, cuts down on waste, and boosts process efficiency in chemical manufacturing.
4. Food and Beverage: People use it for many tasks, like removing solids, particles, and impurities. This ensures products are clear and of good quality.
