Disinfection is the removal, inactivation or killing of microorganisms that may or may not be pathogenic. CRS, utilising proven and innovative technologies, can provide customised disinfection solutions to meet Australian Drinking Water Guidelines or project effluent discharge requirements.

Typical disinfectant processes used by CRS within their systems include:

Chlorine, chlorine dioxide and hypochlorite:
Produces hypochlorous acid in water which disintegrates cell membrane surface lipids and react with enzymes essential for cellular function.
A very strong oxidant that reacts with cell membrane surface lipids and proteins to cause lysis.
Causes dimerisation of nucleobases in DNA, inactivating the ability to reproduce and causes cellular death via apoptosis.

Chlorine-based disinfectants are frequently used due to their ability to maintain a residual as recommended by the Australian Drinking Water Guidelines. The chlorine residual ensures that the effects of any infiltrations by microorganisms during distribution are mitigated.

UV irradiation, filtration and ozone do not leave residuals and thus do not provide long term protection of the water from microorganisms.

CRS can provide skid mounted dosing systems, complete with pipework, instrumentation and chemical storage for connection to existing processes.
