What is the difference between plate and frame filter press?

Plate and frame filter presses are both used for liquid-solid separation in various industries, but they have some key differences in terms of design, functionality, and price.

Plate Filter Press

A plate filter press is composed of a series of plates and frames that are alternately arranged and pressed together to form a filter cake. The liquid to be filtered flows through the spaces between the plates, and the solids are collected on the surface of the plates. The plates are then pressed together to form a cake, which can be easily removed and disposed of.

Frame Filter Press

A frame filter press, on the other hand, uses a frame and a filter cloth to separate the solids from the liquid. The liquid flows through the filter cloth, and the solids are collected on the surface of the cloth. The frame is then pressed to remove the solids, and the filter cloth is cleaned and reused.

Plate and Frame Filter Press Price

The price of a plate and frame filter press varies depending on several factors, such as the size, material, and complexity of the design. In general, a plate filter press is more expensive than a frame filter press, as it requires more materials and labor to manufacture.

A plate filter press can cost anywhere from $5,000 to $20,000, while a frame filter press can cost between $2,000 and $10,000. However, the cost of a filter press can also depend on the specific application, the size of the equipment, and the level of customization required.

Conclusion

In conclusion, while both plate and frame filter presses are used for liquid-solid separation, they have different designs and functionalities, which affect their prices. A plate filter press is generally more expensive than a frame filter press, but it can provide better filtration performance and longer lifespan. When selecting a filter press, it is important to consider the specific requirements of the application, the size of the equipment, and the level of customization required to ensure the best filtration solution.
