Meeting water regulations starts with identification of pollutants.

The ecological health of our rivers, lakes, estuaries and coastal and groundwaters depends on compliance with ever tightening regulatory standards. Your ability to meet stringent water regulations firstly depends on identification of pollutants.

Improvement in analytical technologies and expertise has allowed the identification of a growing number of contaminants which are present in waters at very low concentrations. In many cases the use of conventional treatment methods is often no longer fit for purpose. However, it is unrealistic to expect you to upgrade your entire treatment process each time regulations are amended in order to remain compliant and avoid fines.

Complementary wastewater treatment positioning

Our specialist Nyex™ water treatment systems can be placed in conjunction with other technology with the objective of removing specific contaminants that the existing WWTP is unable to treat. The positioning of the Nyex™ module can vary depending on the existing water technology in place and your treatment requirements.

To understand where Nyex™ may fit within a water treatment train it may be useful to look at our water technology comparison page.

A Complete Tertiary Solution

Our dedicated team of water engineers and scientists supply our customers with the design for a complete tertiary solution to tackle the most challenging waters.

Water Advisory/Analysis Service

A holistic on-site tertiary review is undertaken to identify treatment process suitability, including optimisation to your unique treatment needs and budget; resulting in a tertiary process that is fully operational and right for you.


This service is designed to tackle challenges involving water analysis and characterisation to provide a greater understanding of the necessary treatment options required to meet your unique regulatory or internal environmental targets.


Following a successful treatability trial, a formal proposal will be offered for a solution to your tertiary water issue. This will include a Piping and Instrumentation Diagram for the best proposed set up, empirically informed costing projections and, if necessary, any ancillary technologies which would be provided pre or post-treatment, as recommended by our expert engineering team.
