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.

Flexible industrial wastewater treatment

Our Nyex™ system can be slotted in at various points in your effluent stream to suit your needs.

For example, if you have a side stream which you use to dispose of wash water for your process tanks, our Nyex™ treatment plants can be placed in the side flow, removing harmful chemicals before discharging the effluent to the drain.

By treating the water 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.

Urgent removal of pollutant

Most companies we talk to already have a water treatment plant but they have an immediate problem with a contaminant they can’t treat with their existing set up. Sometimes they are planning to start making a new product and need to find a way to treat the harmful by-products before they can commence production.

In both instances, Arvia is able to help quickly, preventing cost escalation either from discharge fines or loss of production. Typically we can turnaround the initial testing of your water within two weeks which gives you a comprehensive report on next steps and our recommended 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.

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.

The benefits of using a tertiary wastewater treatment are:

Improve the quality of wastewater effluent so it can be reused or discharged without environmental fees.
Integrating an additional tertiary process into an existing treatment train avoids the capital cost of replacing or upgrading the entire water management process.
Manage seasonal effluent within 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 doesn’t generate a secondary waste.

Save money, reduce maintenance

Many industrial and manufacturing clients use a carbon bed to treat lingering organic matter after other water treatment processes like UV or ozonation or on a side stream from a back wash facility.

But because there is no waste from a Nyex™ system and minimal maintenance, we find that some clients are choosing to replace their carbon beds with Nyex™ to avoid costly carbon renewal.

But when does it become cost effective to swap out a carbon bed with a Nyex™ system?

Cost benefits kick in if you are changing the carbon more than every two or three months, so if this is your situation, please contact us for a free discussion.

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.

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.
