Filson Filter Press FAQ:

What is a Filter Press?

Filter press is an industrial dewatering equipment. It uses a special filter medium and exerts a certain pressure on the matters being treated, making the liquid percolate out. On this account, it is regarded as a common solid-liquid separation device.

Filter press was applied to chemical production in the early 18th century, and now is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries.

What is a Filter Press

How does a Filter Press Work?

Though Filson carries full types of filter press, including plate and frame filter press, chamber filter press, membrane filter press and replacement filter press. They have the similar working principle and processes:

  • Filling

During the filling process, solid loaded slurry is pumped under a setting pressure into the filter press chambers through the piping at the stationary head of the filter press. Then the slurry will fill each chamber sequentially.

  • Dewatering ( solid and liquid separation )

This process is also known as compaction or consolidation stage. Once the chambers are filled, the slurry that is being pushed by the feed pump will force the liquid out of the chambers. It is in this stage that the filter cake achieves maximum dryness.

  • Cake washing and air blow

During this process, it is possible to flush undesirable components using water or an appropriate solvent. Also, you can choose to blow the cakes with clean air to realize additional moisture reduction.

  • Discharge

It is the last step of the filtration cycle. It aims at removing the dewatered filter cake. Each filter element is opened up and separated for cleaning and solid discharge. Usually, the cakes fall off by gravity.

How does a Filter Press Work

How Long does a Filter Press Cycle Take?

The answer is that it depends…

Typically, the filter press cycle time contains two parts: the filling time and a constant. In which a constant is composed of close and open press, filtration, air blow and discharge time. And if additional operations, like cake washing and compression, are required in a particular application, the constant would be longer.

How Long does a Filter Press Cycle Take

How Long does a Fill Cycle Take?

A fill cycle is determined by many different specifications, you can check the factors listed below:

  • The nature of the material to be dewatered
  • The concentration of the solids in the slurry
  • The thickness of the filter cake
  • The feed pressure
  • The selection of the filter cloth

How to Select the Right Filter Cloth

When do the Cloths Need to Be Cleaned or Replaced?

Filter press cloth is used to collect solid matters in the slurry and helps improve the filtration efficiency. So after a period of using, you are recommended to clean or replace your cloth.

When your filter press cloth becomes wet, sticky and not dry as usual, it’s the sign that the cloth needs to be cleaned. ( Some cleaning methods are listed below. ) And if you have already cleaned the cloth and the efficiency is still not increased, then it’s time to replace it with a new one.

The life of your filter press varies from installation to installation. And it is influenced by frequency of use, cleaning method and proper maintenance, as well as the type of sludge being treated. Typically, for most installations and press types, the filter cloth could last up to 6 months.

Filter Cloth Cleaning Method:

  • Acid washing
  • Acid dip washing ( soaking in 3-5% acid and water mixture )
  • Power spray washing

When do the Cloths Need to Be Cleaned or Replaced
