MOBILE FILTER PRESS PLANTS

Sludge dewatering in municipal or industrial waste water treatment is classified as complex. Not only the composition of the sludge, but also the economic and technical boundary conditions of the plant vary greatly. The optimal solution can only be reached by analysing the overall situation. Minimising dewatering costs while simultaneously reducing residue quantities are also clearly defined objectives for users. Accordingly, a stationary filter plant can only be used with a low degree of utilisation. Cost-intensive investments are therefore often offset by moderate capacity utilisation.

 

ECONOMIC APPLICATION MOBILE FILTER TECHNOLOGY

 

The more specific a process-technical plant, the higher the associated investment costs. Especially in industrial waste water treatment plants, this fact inevitably leads to an economic conflict situation. Efficient and technically superior dewatering systems such as filter presses are characterised by relatively high investment costs and low plant utilisation. In addition to the semi-mobile filter presses, the mobile filter press plant is the answer to the question of an economical yet self-sufficient filtration method. Practical experience shows that the ratio of investment costs compared to a short to medium-term acquisition of a mobile filter press can be in the range of 1:3 to 1:15. Similar conditions can also be observed with regard to operating costs.

MSE mobile filter presses are fully equipped and immediately ready for operation after connection of the sludge, water and power supply. In this way, the best possible result can be achieved for every task. MSE Filterpressen® also helps you with the planning and assembly of your individual plant. At this point, mobile filter presses are particularly suitable for dewatering sludge from several plants at regular intervals or for compensating capacity peaks and bottlenecks. The fact that mobile filter presses are not subject to approval obligation and are therefore quickly and unbureaucratically available is particularly interesting.

TECHNOLOGY OF MOBILE FILTER PRESSES

 

Mobile filter press plants can be implemented in many different designs. Chamber filter presses or membrane filter presses (with 16 bar or 25 bar operating pressure) are optionally available and depending on the application, also the appropriate feed pump (piston membrane or eccentric screw pumps). The sizes of the mobile filter presses are available up to a maximum size of 1200. This corresponds to about 100 chambers and about three cubic meters of chamber volume. The mobile filter presses are delivered on a semi-trailer or truck trailer, according to the dimensions and the permissible weights pursuant to Road Traffic Licensing Regulations. The conditioning of the sludge is mainly carried out with polyelectrolytic flocculants (PE). Further methods are lime/iron conditioning and dosing of solid filter aids. The plants are therefore equipped with suction and pressure-side inline mixers. The PLC plant controls the conditioning parameters in proportion to pressure and/or volume.

MAXIMUM VERSATILITY DUE TO EXPANSION AND AUTOMATION OPTIONS

 

All filter press plants are equipped with the necessary equipment such as sludge feed, polymer preparation plant, screw conveyor for cake discharge and much more. One operator is sufficient to operate a mobile filter press. However, the operator’s tasks are limited to monitoring the plant and unloading the filter press after each batch.

OPTIONAL MACHINE EQUIPMENT

automatic plate shifter for filter press - working principle

The automatic plate shifter has the task of moving the individual filter plates or the filter plates connected to form a package for discharging the filter press. Experience has shown that this is done manually for smaller filter presses. With larger plate sizes, however, plate shifting is more difficult and requires a plate shifting system. This system makes handling much easier.

working principle of a membrane filter press with squeezing unit

Filter presses greatly influence the degree of dryness of the solids through the use of membrane technology in the filter plates. In this process, a flexible, impermeable membrane attached to the carrier body compresses the cake in the chamber after the feeding process is completed. Depending on the degree of dewatering, different dry substance contents (dry substance content – percentage by weight of dry substance in the filter cake) can be achieved in the filter cake by re-pressing with membrane plates.

filter cake washing - working principle

Filter cake washing, especially in combination with membrane technology, is an optional process step in filter cake post-treatment. This involves chemical/physical treatment of the filter cake or replacement of the filtrate still contained in the filter cake by a washing medium. The dewatering properties of the suspension determine the required filtration or washing pressure. In addition, the maximum permissible pressure depends on the following factors:

  • On the permissible operating pressure of the press frame.
  • From the permissible pressure and temperature stress on the membrane filter elements

core blowing and core rinsing - working principle

In a wide variety of filtration applications, filter cake may not be able to form completely in the turbidity channel (in the inlet area of the filter plates). Whereas in other applications, e.g. fully automatic filter presses, a solid filter cake in the turbidity channel is not desired. If a liquid slurry remains in the turbidity channel after filtration without core blowing, it escapes when the plate pack is opened, which can cause correspondingly serious problems. Soiled filter cloths or deposits on the lower edge of the filter plates are just a few of the undesirable effects. Poor filtration results and high mechanical loads for the fiter press are the consequences.

filter cake blow drying - working pronciple

Residual liquid in the finished filter cake and between the filter cake and filter cloth can never be completely excluded. This results in high and unnecessary disposal and transport costs. The filter cake is dried by compressed air. The compressed air from the pressure plate shoots through the filter cake to the washing plates. The residual water runs off via filtrate drains provided for this purpose. The compressed air forces part of the capillary water out of the filter cake. In this connection, the capillary water adhering between the filter cloth and the filter cake is reduced. This consequently leads to an improvement in the dissolving behavior and the dry substance content (DS content) in the filter cake.

With the versatile applications of a chamber filter press as well as membrane filter press, breakthroughs of the slurry can occur from time to time. To keep contamination of the environment as minimal as possible as a result, there are various options. In addition to a splash guard, a preliminary leakage test is used to check the filter plate package for leaks and preventively minimize damage. How does this work? Contact us!

Extension of the filter press with a spacer

The removable spacer is the ideal solution if you want to secure the possibility of expanding the capacity of your filter press in the future. In doing so, you are spared the need for another new purchase. Each new filter press is optionally and upon request expandable with a spacer for future plate expansions. If a larger capacity intake is required, the cylindrical spacer, which is attached to the hydraulic cylinder and the moving pressure plate, can be removed quickly and easily. The filter press can thus be supplemented by the additional filter plates. However, the maximum capacity expansion depends on the filter press architecture. We will be happy to advise you on this.

Based on the decisive properties of the flexible material, rubber coated filter presses are used primarily for the filtration of particularly aggressive slurrys, such as solvents or acids. In this context, conventional painting of the steel parts is no longer sufficient. In a complex process, the supporting filter press components are accordingly coated with a layer of 3mm thick rubber. In the case of the rubber-coated filter press, the hydraulic column, charging column, pressure plate and support bars are hard rubber-coated for this purpose, and smaller components are made of polypropylene. It is also possible to rubberize only the components that come into contact with the product, such as the charging column and pressure plate. The composition of the rubber coating depends on the special surface requirements of our customers.

PROCESS TECHNOLOGY

Cake filtration is a mechanical process for the separation of solid-containing liquids. It pertains to surface filtration like cross-flow filtration. In contrast to depth filters, the actual separation effect takes place through the filter cake, which settles on the filter cloth.
