Enhanced Treatment Capabilities

Placed up/downstream from existing treatment processes to improve treatment capabilities

The introduction of legislation which help to protect and improve the ecological health of our rivers, lakes, estuaries and coastal and groundwaters has led to greater reliance upon tertiary treatment methods to maintain compliance with ever tightening regulatory standards.

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

Arvia’s packaged Nyex™ treatment systems retrofit into an existing treatment train to improve treatment efficiencies. By selecting an integrated solution at the source of contamination, recalcitrant compounds are prevented from mixing and reacting with one another in final effluent – potentially becoming more complicated to treat.

What are the benefits of adopting an advanced tertiary treatment process?

Water is complex and often requires various treatment steps to ensure it is of a sufficient quality for its intended purpose, with each step addressing different water quality issues. Each process has limitations and are best placed in combination to deliver water of an appropriate quality. In general, most treatment trains involve a primary, secondary and tertiary process and in some cases a quaternary stage.

Tertiary treatment is often one of the final cleaning stages which improves the quality of the wastewater effluent following primary and secondary stages before it is reused or discharged. Integrating an additional tertiary process into an existing treatment train avoids the capital cost of replacing or upgrading the entire water management process. This allows amendments to seasonal manufacture as well as environmental regulation without the headache of a complete process revamp.

Arvia’s patented Nyex™ treatment technology combines filtration (adsorption) with oxidation in a single step and hence provides the added benefit of reducing interdependencies on multi-stage treatment trains and also offers an alternative to existing technologies that generate a secondary waste.

Selecting the most appropriate treatment train will help an organisation to avoid harming the environment, human health, and equipment, process or products. It will also help avoid severe fines and legal action arising from wastewater being improperly discharged to either the environment or municipal treatment works.

What do wastewater regulations say?

For wastewater treatment where effluent is discharged to the local sewer, the local utility stipulates the cost to manage this water based on the industry, level of contamination and flow rate. This calculation is based on the Mogden Formula.

If water contains specific contamination which may damage the municipal facility, utilities can refuse to accept this effluent and breaches to this request come with substantial fines. This challenge results in many industries paying for specialists to collect, truck and treat their used water off-site, which involves high recurring costs and environmental impact.

As such, there is need for an alternative solution which targets the problematic contaminant, leaving water safe for discharge to the sewer or the environment.

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.
  • Treatability – 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.
  • Advisory – 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.

How do Arvia’s services and technologies help to enhance treatment performance?

  • Could you reduce water demand and save utilities spend at your facility? An on-site assessment by one of Arvia’s experienced Process Engineers identifies opportunities for more efficient water usage and treatment.
  • Arvia is a supplier to end users and Original Equipment Manufacturers (OEMs) and Engineering, Procurement and Construction (EPC) companies who are looking for the highest quality solutions which easily integrate to complement other treatment processes.
  • Highly successful as stand-alone solutions, the Nyex™ systems are extremely adaptable and can also be utilised to complement other existing or planned treatment processes. Arvia has over 10 years’ experience in the design and integration of Nyex™ systems into existing and planned treatment trains.
