Wastewater FAQ’s

Have a question about Arvia or how our treatment process works?

Low and trace concentrations of organics and non-biodegradable organics.

The system is modular in nature, meaning that more modules can be installed to cope with changes in regulation, to tackle emerging contaminants or increases in manufacturing capabilities. There is not a minimum or maximum flow rate.

The system can be stored freestanding, skid-mounted or incorporated into concrete basins and can also be containerised for storage outdoors.

As the COD concentration of water increases, the amount of energy required for adsorbent regeneration increases. The process is most cost effective for low concentrations of organics.

Nyex™ media will undergo some minor physical attrition due to electrochemical damage over time and will therefore need ‘topping-up’ by around 2-4% per year on average. Operating at lower current densities will minimise this. Adsorbent attrition can also occur due to excessive backwashing so it is advised to operate with low solids to preserve the Nyex™ media.

Increased salt will increase the conductivity of the water. This results in a reduction in the voltage required, which lowers operational costs. The Nyex™ system has been tested on streams of up to 15% sodium chloride.
