Increased water scarcity and hikes in water rates makes water reuse an attractive option to ease water dependency. Arvia Technology helps companies ease their water dependency by reducing the amount of RO reject water.
Although Reverse Osmosis is a powerful and versatile water treatment, issues can arise due to fouling, scaling and more importantly, chemical attack.
Historically, Granular Activated Carbon (GAC) filters have been used to remove organics and residual disinfectants from pre-treated water, as these can attack the membranes leading to inefficiency – and eventually damage them.
However, a GAC bed also has its drawbacks, primarily the fact that it loses its efficiency after a period of use leading to the requirement to take the array off-line and replenish the adsorbent media.
This media then needs either reactivating by a specialist contractor or dumping in landfill. Neither option is environmentally positive and both lead to additional expense and potentially interrupted production.
Over the last 15 years, Arvia Technology has been developing a range of tertiary water treatments that out-perform GAC systems without any of the drawbacks normally associated with them.
Using an innovative combination of electrochemistry and adsorption, Arvia’s Nyex™ water treatments can safely remove many recalcitrant compounds and polluting chemicals without requiring constant media replacement and without the addition of any hazardous chemicals. For a full description of how our systems work, see this page.
Nyex™ treatment reactors can be used in sidechains (especially in two-part or double-pass RO systems) to purge organics from the primary stage concentrate water, increasing the efficiency of subsequent RO stages.
By utilising Nyex™ water treatments in either a sidechain or as initial purging, more water can be recycled, especially important to facilities aiming towards Zero Liquid Discharge (ZLD).
Many polluting organics and a whole slew of other recalcitrant compounds can be treated to result in concentrations of parts per billion. For the whole range of of pollutants treated, go here.
GAC systems tend to lose their efficiency over time.
Substituting a Nyex™ water treatment will slow down damage to membranes and therefore result in a more efficient and effective water treatment train.

Nyex™ systems have no moving internal parts which leads to lower maintenance and less staff training. To install, simply connect up the water inlet and outlets and the power cable.
Nyex™ reactors have a small footprint; individual units can easily be mounted on a skid to allow easy placement by forklift or even in a shipping container and placed outside. Adding capacity is as simple as hooking up another unit in parallel. Multiple arrays can also be set into tanks.
Unlike many standalone systems, ours do not require complex start-up processes making them ideal for batch processing or testing. Simply press START and the system gets to work, reaching maximum efficiency quickly.
Nyex™ systems can be adjusted to deliver a pre-set treatment level to maximise efficiency whilst controlling energy costs.This means it is a cost-effective solution of delivering reliable water treatment.
Having no moving parts also means that systems can be sited remotely as they require so little maintenance or operator intervention. As a result, staffing costs can be reduced leading to greater efficiency
No toxic sludge is produced by Nyex™ systems and our unique adsorbent media only needs a 1 – 3% top up approximately once a year. This compares favourably with other techniques like GAC which often need production to be paused whilst media is replenished.
An Arvia Nyex™ tertiary water treatment system out-performs many ‘legacy’ products currently in use throughout industry.
