Arvia destroying pollutants in waste water

Challenge

Developing an economic process for removal of toxic or non-biodegradable micropollutants.

Problem

Water is becoming increasingly important globally, with enhanced water quality and greater conservation driven by public awareness, rising costs and more stringent legislation. Treatment of low concentrations of organics in water, wastewater or industrial process streams is normally very difficult to achieve economically. The ever-increasing quality requirement for treated water generally demands greater capital and operational costs for the add-on of existing process technologies.

Solution

Arvia Technology has developed a water treatment process that continuously removes and destroys toxic and non-biodegradable pollutants. The process offers a sustainable replacement for activated carbon and relies on a highly-stable adsorbent called Nyex, and operates without any mechanical moving parts. The process can handle high and low concentration streams, and destroys chlorinated compounds preferentially.

The process is extremely cost-effective; typically, cost is directly proportional to the quantity of micropollutants to be removed from the incoming effluent. Micropollutants can affect colour, odour, and quality of drinking water. The process enables reuse and recycling of water, and due to full destruction of the pollutants, does not leave secondary waste requiring further treatment.

The Arvia solution can be implemented for multiple uses across a wide range of industries to address many, diverse needs, such as:

  • final stage effluent treatment
  • drinking water
  • industrial process streams
  • selective removal of chlorinated organic compounds
  • odour treatment
  • complementary treatments

Benefits

Modular design can be scaled for all treatment requirements
Low whole-life costs
No offsite regeneration or landfill costs
Low amounts of adsorbent (Nyex) required
Treatment of industrial process streams enables energy and water usage savings
Safe and simple operation with low maintenance
Fully automated, continuous operation with no internal moving parts
Easy installation or retrofit with a small footprint
High-quality effluent suitable for reuse/recycling
No added chemicals
The use of Arvia’s process with existing technologies can reduce energy requirements and lower operating costs, for example:
  • UV Treatment – the Arvia process can be used in conjunction with UV treatment, for example to remove trihalomethanes (THMs), trichloroacetates (TCAs) or residual colour
  • Membrane Treatments – the Arvia process can be used to treat concentrate streams and is complementary to lower-cost membranes, such as ultrafiltration
