KOMPaion-SAT-line: filtration systems for the clearing of treated wastewater


Application fields

The refiltration systems of the KOMPaion-SAT line are used for the secondary cleaning of treated waste water. One of the versatile application fields of ion exchangers is utilized here.

Further application fields are:

  • Fresh water desalting
  • Recycling technology
  • Circulation of final rinses

All ion exchangers have one thing in common: They can only operate in clean solutions. Oils and fats must be kept away. Any contained solid matters (hydrolysis products, dirt) must be removed before the ion exchange.

General process description

The heart of the ion exchanger system is the exchanger resin. The porous plastic spheres are able to absorb dissolved saline substances from the water and release them again during the regeneration with acid or lye. The resins are filled into filter columns and the water to be purified is passed through them.

In the KOMPaion-SAT series systems, loading is effected in a down-flow and regeneration in reverse current/up-flow.

Description of system

The systems of the KOMPaion-SAT line have the following construction.

  • Storage tank, optionally with pH adjustment
  • Charging unit (double pump station)
  • Prefiltration (simple or double sand filter / cartridge filter / bag filter)
  • Selective exchanger
  • pH correction stage

With the selective exchanger systems of the KOMPaion-SAT line, the two-way circuit/series connection is employed due to the case of application. Here, the two cation exchangers are operated alternately in a series connection. The first exchanger column functions as the working filter, and the downstream column as a guard filter.

The operation of the system is subdivided into the following main steps:
Loading: Removal of heavy metals from clarified water.
Regeneration: Reactivation of the active exchanger groups by means of an acid.
Conditioning: Preloading of the exchanger groups with lye.

Advantages

  • Optimal utilization of resin capacity by pH adjustment
  • Best metal minimization in the outlet by adjustment of the optimal pH value
  • Low investment costs thanks to a simple construction of the pipe battery
  • Modern control concept with central PLC unit
  • Automatic progress of the individual regeneration steps
  • Minimum operating efforts
  • Particularly clearly arranged pipe battery without dead volumes
  • Patented regeneration system
