Tobacco processing facilities have been looking for more cost-effective and sustainable methods which are in-line with their water management plans.
Fresh water costs have been rising, along with wastewater disposal costs. Many businesses are starting to think about water reuse as a way to save money and reduce environmental impact.

To reuse process water in a cost effective way, it is necessary to determine exactly which pollutants need to be removed for each purpose.
It can be much cheaper to remove pollutants from water for reuse than to pay for discharge fees plus the cost of buying more fresh water.
In this case, our client was looking for a complete closed-loop solution in which Chemical Oxygen Demand (COD) would be reduced from 50mg/L to as close to zero as possible. This wastewater could then be reused for other purposes around the facility, including cleaning.

Arvia’s Nyex™-a system was deployed which combines adsorption with electrochemical oxidation in a single, scalable unit. Since this case study has been written, this product has been superseded by our new enhanced technology, Nyex Rosalox. You can see how this technology works in the animation here.
In both products, organic contaminants are preferentially adsorbed, localising them onto the surface of the carbon-based Nyex™ media. A low electrical current is then passed through the media bed which fully mineralises the adsorbed contaminants to H₂O, H₂ and CO₂. The electrical current simultaneously regenerates the surface of the media in-situ, allowing for further adsorption and treatment without interruption or incineration.
Results are achieved without chemical dosing or the generation of sludge reducing costs in terms of labour, transport of chemicals and specialist waste disposal.

The project involved the treatment of wastewater using a Nyex™ 1-20a system at the client’s site of wastewater taken at the final stage of their existing treatment train, for advanced ‘polishing’ treatment.
The inlet water was analysed at a COD level of around 50 mg/L and final samples were just above the limit of detection, as requested.
The energy consumption was very favourable at 2.16 kWh/m3.

Trial showed 96% reduction in nicotine after 1 hour from an inlet nicotine concentration of 9.84 mg/L.
03.30.2021
Easily achieved the 99% Nicotine removal, consuming 10.4 kWh/m3, which saved our client large incineration costs.

Safe discharge enabled by reducing COD to 31 mg/L and removing all colour from effluent.
We remove APIs and hard-to-treat micropollutants from wastewater for pharma, CDMOs, animal health, biotech and biopharma sectors.
We help specialty chemical companies clean their process water, removing active ingredients, biocides, recalcitrant COD and micropollutants.
Our industrial wastewater treatment process is very effective in removing organic chemicals such as pesticides, herbicides and insecticides.
We provide industrial wastewater treatment solutions removing biocides and other micropollutants in wash water and blowdown water.
Our aquaculture wastewater treatment removes pesticides used to treat sea lice, as well as medicines and off-flavours found in RAS facilities.
