Modern multifunctional filtering equipment for separating slurries and dewatering of various types of industrial pulps and sludges from treatment plants.

Chamber Membrane Filter Press is a modern multifunctional filtering equipment for separating slurries and dewatering of various types of industrial pulps and sludges from treatment plants. A filter press is a periodic-operation equipment designed to filter slurries under pressure.

Scope of application of chamber membrane filter presses

  • water treatment;
  • ceramic industry;
  • cement industry;
  • biotechnological industry;
  • pharmaceutical industry;
  • food industry;
  • chemical industry;
  • metallurgical industry;
  • mining and processing industry.

Principle of operation of EKOTON Chamber Membrane Filter Press

The filter press consists of a pack of filter plates that are suspended on the top or side beams. The working cycle begins with clamping the filter plates. When the filter press is clamped, the inner chambers of the individual plates are connected to form a combined chamber space. When the external pump is switched on, the slurry gradually fills the chambers of the filter press. Under the pressure of the pump, the liquid phase passes through the filter cloth and is removed from the chambers of the filter press through a system of internal channels. The solid phase is retained on the filter cloth, forming a filter cake layer. After filling the chamber with cake, the feeding is stopped.

After filtration, the cake in the chambers of the filter press can be washed and dried. During washing, a washing liquid is supplied to the filter press, which squeezes out the remains of the main filtrate from the pores of the cake. Washing can be carried out simultaneously with membrane squeezing. In this case, the quality of washing improves, and the consumption of washing liquids decreases.

During drying, compressed air is passed through the cake in the chambers of the filter press. After filtering the washed, filtered and dried cake is discharged from the filter press. The clamping plate moves to the “filter press open” position. Gaps with a width exceeding the thickness of the cake appear between the filter plates. Under the influence of gravity, it falls through the openings into a receiving hopper or onto a transport device.

What is the difference between the Membrane Filter Press and the Chamber one?

Filter presses can be equipped with membrane filter plates. They differ from ordinary chamber filter presses in that the filtering chamber is equipped with a movable partition – a membrane. When air or water is supplied under the membrane, it presses on the cake over the whole area, which leads to technological advantages.

What are the benefits of using membranes?

  • Increased filtering performance
  • Obtaining a discharged sludge when the filtration properties of the slurries deteriorate
  • Additional reduction in humidity during high-pressure squeezing.
  • Reduced consumption of washing fluids and air for drying compared to the chamber version.

The standard version is a mixed plate package in which each even plate is a membrane plate, and each odd plate is a chamber one. Thus, in each chamber one of the walls is a membrane.

Advantages of Ekoton Chamber Membrane Filter Press

  • High reliability of construction
  • Ease of use and maintenance
  • Large filtering surface
  • The ability to use high pressure in working with poorly filtered slurries.
  • High corrosion resistance due to the use of corrosion-resistant materials in the construction
  • Modern automation system.
  • Low humidity of the cake
  • Minimum amount of washing water and low air consumption when drying
  • Low energy consumption
  • Long service life of filtering cloth
  • Simple cake and filtrate discharge

Automation of Ekoton Chamber Membrane Filter Press

EKOTON chamber membrane filter presses are equipped with various control and measuring devices and equipped with a control system based on an industrial controller. The control system controls the mechanical movement of individual units of the filter press, the process of technological operations, the operation of peripheral equipment.

The level of automation of EKOTON filter presses is chosen depending on the size of the filter press, the tasks to be solved, and the frequency of operating.

How does the filter press presses the slurry?

The filter press does not press the slurry. The word "press" means filtration under pressure, which is generated by external equipment. The hydraulic cylinder for clamping the filter plates serves to seal the chamber space.

How are the peculiarities of different types of production taken into account for chamber-membrane filter presses?

Depending on the technological task, the size and number of filter presses, the type of cake discharge, the configuration of the valve-manifold system, the level of automation, the type and characteristics of the associated equipment are selected. The selection of the filter press and its configuration is recommended to provide based on the results of pilot tests in the Ekoton laboratories or at the customer's site.

Which filter press is better - chamber or membrane?

In the general case, it is a membrane one - it allows to get a good result even with wide range fluctuations in the filtering properties of the slurry. In the conditions of stable operation of the previous process sections, as well as when filtering easily filterable slurries, a chamber filter press can be used to reduce capital and operating costs.

What does the designation FM-16.150.40-H mean?

  • F - designation of the standard size of the plates: 1200 x 1200 mm
  • M - version: membrane
  • 16 - maximum pressure in the chambers: 16 bar
  • 150 - filtration surface area: 150 m2
  • 40 - maximum cake thickness: 40 mm
  • H - type plates suspension: over-head

Does the throughput of the filter cloth decrease during operation? How long does the cloth operate? Is it possible to regenerate it?

Ekoton filter presses use two filter cloth regeneration systems - pressurized water and chemical (CIP). For small filter presses of sizes A, B, C, a portable high-pressure washer is included in the set; starting from size D, filter presses are equipped with an automated washing device. Regeneration with water under pressure is usually carried out every 12 to 36 hours, depending on the operating mode of the filter press. For those cakes, the deposits of which can be dissolved in the pores of the filter cloth, filter presses are equipped with a chemical regeneration connection line. The service life of the filter cloth can be several weeks, up to several years, depending on many factors, including the timeliness and frequency of regeneration.

In which areas of the food industry is the filter press used?

First, this is the production of sugar, palm and sunflower oil
