KOMPaion SAT-Line

Selective Ion Exchange Units

 

Application

The polishing filter units of the KOMPaion-SATLine are used for the post cleaning of effluent after conventional treatment. This is one of the application of the versatile separation process of ion exchange.
Other kinds of application:

  • Deionization of tap water
  • Metal recovery
  • Loop recycling of rinse water

Prefiltration is a basic requirement for all ion exchange applications. Oil and grease must also kept out of the system; when present, they are typically removed by prior micro- or ultrafiltration. Any particulate matter or products of hydrolysis are retained by prefiltration in multi-media or cardridge filters.

Process Characteristics

The proper selection of ion exchange resins is of importance. Most ion exchange resins in use today are synthetic organic materials made up of macroporous matrix which are able to adsorb ionized substances in solution and release them again in concentrated form during regeneration phase.

The ion exchange resins are filled into fibreglass laminated columns. The feed stream is pumped through the resin bed in down-flow mode.

Description of plant

The different units of the KOMPaion-SAT-Line includes the following assembly groups.

  • Raw water collecting tank
  • Feed pumps (dual pumping station)
  • Pre filtration (single or dual filter)
  • Selective ion exchange columns
  • pH-correction unit

The configuration of the KOMPaion-SAT-Line combines and incorporates the advantages of both the series and the dual train configuration. Because of the special application the selective ion exchange columns operate in a alterning cross-over array. In this system the two cation exchangers operates alternating in a series train configuration. The first exchanger column is used as work column and the second as a polishing (safety) filter. The operation of the plant is divided in following main steps:

  • Running: Removal of traces of heavy metals from clarified water
  • Regeneration: Activation of the active exchange groups with acid
  • Conditioning: Pre loading of the exchanger groups with Lye
