Chamber filter press

Chamber filter press for purification (filtration) of residual/wash water with bindable fine particles (cement).

Residual water and wash water can be purified with a chamber filter press. Here, the fine particles in the residual and wash water are removed, so that purified water is available after the process. With all processes, the residual or wash water is supplied to the filter press either directly or from an agitator tank. The pH value can also be reduced from 11 to 13 by further treatment of the purified water.
Using a chamber filter press, residual/wash water can be filtered down to a few μm The press consists of several filter plates arranged in a row. The plates are enclosed by a filter cloth that retains the coarse particles. During the operation of the chamber filter press, the filter plates are compressed under high pressure, and the residual/wash water flows between the plates from the inside out. Here, the fine particles contained are separated. A filter cake forms.

The filtered water can be used in two ways:

  • Storing the clear water in a clear water tank for mixing new concrete
  • Reducing the residual water density in the agitator tank to a desired value

Once the chambers are completely filled with filter cake, the cake is removed. The filtered water is collected and flows into a buffer tank.
The resulting filter cake is either disposed of or reused (e.g. as filling material for road construction). The purified water collected in the buffer tank can be reused in the production cycle.

A container enclosure allows the chamber filter press to be housed safely during the winter. The housing itself is isolated to enable smooth operation in winter. For even better protection against the cold, the discharge opening can be equipped with an automatic closing flap.

The technical advantages of the chamber filter press at a glance

  • Purification of residual/wash water with fine particles (cement) that have binding properties
  • Purification of coloured water
  • The water content in the filter cake is only approx. 25 % (watertight)
  • Simple handling of the filter cake
  • Little space required, high filtration performance of the system
  • Low assembly costs
  • Low operating and maintenance costs

The economic advantages of the chamber filter press at a glance

  • Reduction of water costs by reusing the filtered water
  • for the production of concrete
  • for surface treatment (e.g. concrete blocks, paving stones)
  • for cleaning mixers, bucket conveyors
  • Avoidance of wastewater charges and waste disposal costs 

Furthermore, the BIBKO® chamber filter press can be equipped and supplied with the following options:

  • Different isolated containers with stair case as winter-proof enclosure
  • Automatic closure of filter cake discharge opening to avoid danger of frost in winter
  • Densimeter
  • Automatic acidification of the filter cloths
  • pH neutralization
  • Residual water basin and clear water basin
  • Mobile systems

Water purification systems

DSCF0223Chamber filter press

BIBKO® recycling systems can be supplemented by appropriate water purification systems such as chamber filter presses, treatment towers and hydrocyclones.

External bucket elevator

externes BecherwerkExternal bucket elevator

The external bucket elevator is an alternative to the pump discharge conveyor. This bucket elevator is located on the main shaft of the ComTec recycling system model. The attached buckets take up the wash water, as well as the residual material, and feed it to the actual recycling system.
In addition, the external bucket elevator allows collected wash water (e.g. from the mixing plant) to be fed into the recycling system.

Sand and gravel separation

Sand-gravel separation makes it possible to separate the recovered components of the concrete (sand and gravel) into two or more parts.
