Contamination removal is vitally important in the production of safe drinking water.

The removal of contaminants is crucial for the environment and to ensure  the legally responsible release of wastewater.

Over the last century large amounts of water contamination have been, and continues to be, released by various industries threatening the environment and human health.

Currently there is a growing awareness of the impact of these contaminants on:

  • Groundwater
  • Rivers
  • Lakes

How are contaminants removed from water?

Traditional purifying technologies include:

Thermal Technologies:Contaminated drinking water - contamination removal

  • Multi effect distillation
  • Multi stage flash distillation
  • Vapour compression

 

Membrane Technologies:water bubbles

  • Reverse Osmosis
  • Nano Filtration

 

Electrochemical TechnologiesWater needs to be safe for the environment - contamination removal

  • Ion Exchange
  • Capacitive Deionisation
  • Electrodialysis

Capacitive Recovery 

Our CRS technology falls in-between Electrochemical and Membrane technologies. Cherry picking aspects of both these processes.  

CRS purifies water effectively and at very little cost.

Why choose CRS over traditional water contamination removal technologies?

Performance

Capacitive Recovery has a unique ability to remove a wide range of ionic contaminants dissolved in waste water including:

  • Arsenic
  • Ammonia
  • Nitrates
  • Hardness
  • Heavy metals
  • Iron
  • Boron

High water recovery

Compared to conventional Reverse Osmosis systems that typically waste more than 50% of water. Capacitive Recovery systems waste less than 20%, resulting in long-term conservation of ground water.

Low operating cost / energy usage

Capacitive Recovery requires no chemical cleaners and consumes minimal power. There is no high pressure pump repair or maintenance, no high pressure membranes and no moving parts.

Reduced fouling

The capacitive recovery process involves regularly reversing polarity, acting as a self-cleaning mechanism. No chemicals are required to clean the system

Size and simplicity of CRS Systems

A typical Capacitive Recovery System requires less space to operate than alternative technologies and the systems can be managed with no specialist training

Retention of minerals for drinking water

Capacitive Recovery Systems have the flexibility to retain desired levels of minerals to meet WHO standards for mineral content. This is vital in drinking water applications. It does not necessarily lead to complete demineralisation.
