Arvia Technology Ltd develops highly innovative new solutions for the destruction of aqueous organics in water and waste water treatment that are cost and energy efficient and chemical and waste-free. It is based on the multi-award winning, patented platform technology of adsorption and electrochemical regeneration. Whilst originally designed for water and wastewater treatment, Arvia were pulled into the nuclear industry to treat radioactive organic waste streams that were unable to be treated using conventional processes. One class of compounds that falls into this class are degrading active ion-exchange resins. These materiasl cannot go for long term storage as they are too unstable. Hence they are currently stored at nuclear sites. Arvia has not been able to treat these wastes as they are in solid form, but an American company, Kurion, has developed a liquifaction technique that produces an aqueous waste. This project involves developing the process stream to take these solid active wastes, liquify them and treat this liquified waste in the Arvia Process. The resulting active water from this process can then be treated by conventional techniques.

Some of the most significant radioactive risks are present in the legacy fuel storage ponds at Sellafield. These are 50 - 60 years old and are in need of major attention. However, the presence of algal and bacterial blooms in these ponds is hindering in the retreival process, slowing down the rate of reducing the hazard. This project will aim to provide a novel treatment approach by using a subersible system to treat the water. Based on the Arvia process of adsorption coupled with electrochemical oxidation, this approach has the benefit that it requires no space around the tanks (which are heavily congested); does not require the removal of radioactive water from the tank (reducing risk); makes use of the existing tank and water (reducing shielding requirements) and will require minimal operator involvement (minimising operator dose). In addition if this treatment process is proven for a site like Sellafield, it opens the market for this technology for other nuclear operators. A key possibility would be the treatment of water stored in the storage tanks at Fukushima, where a large number of units could be deployed to make the tank water suitable for further treatment.

The joint advancement of Arvia™s second generation, newly patented organic destruction technology from a technology readiness level of 2/3 to 6/7 by testing it in the National Nuclear Laboratorys Central Laboratory on high-alpha contaminated organic wastes, for which current treatment options are suboptimal or non-existent. Recently Arvia™, a multi-award winning SME, has demonstrated the oxidation of low and intermediate level waste radioactive oil at a Magnox Ltd. site. Commercial opportunities in the treatment of high-alpha contaminated organic wastes have driven this further innovation of Arvia™s technology. Arvia™ and NNL have access to expertise and facilities that will fully support the project objectives to design, build and test the technology and to evaluate its potential to be taken forward into an industrial product. An anticipated end user, Sellafield Ltd., has expressed written support of and commitment to the project.

Arvia Technology has developed an award winning technology for the destruction of organics in water and wastewater using a patented adsorbent material, Nyex®. It has been recognised as innovative and sustainable by awards from various professional organisations (IChemE, IET, RSC etc). The aim of this project is to investigate the properties of the process for the treatment and reuse of industrial process water, specifically the recovery of water from pulp and papermills for internal reuse. To date the technology has been proven at small scale, but to enter the market for industrial effluent recycling it is essential to prove the technology at a large scale. Demonstration of the components for a large scale and their incorporation into a 500m3/d unit is proposed to prove the process at a level suitable for introduction to this market. The pulp and paper industry has been chosen as it is a major user of water and UPM is keenly looking for technologies that will reduce the water footprint.

A waste product from the generation of electricity in nuclear power plants is radioactive oil. High activity oils have traditionally been stored on site as no technology exists for their safe and economic disposal. The Arvia Process of adsorption and electrochemical destruction has been shown to successfully eliminate the oils from an aqueous phase, but this project is looking to prove that no oils remain on the solid adsorbent after regeneration, using a novel extraction technique.

Arvia Technology Ltd develops highly innovative new solutions for the destruction of aqueous organics in water and waste water treatment that are cost and energy efficient and chemical and waste-free. It is based on the multi-award winning, patented platform technology of adsorption and electrochemical regeneration. Whilst originally designed for water and wastewater treatment, Arvia were pulled into the nuclear industry to treat radioactive organic waste streams that were unable to be treated using conventional processes. Some of these orphan wastes have been stored on site for the last 30 – 40 years. Over the last three years Arvia have worked on developing a solution for destroying radioactive oils culminating in a full scale demonstration plant at Magnox’s nuclear decommissioning site at Trawsfynydd. Arvia are currently contracted by Magnox to design a plant to destroy the remaining radioactive oils at Trawsfynydd. As well as proving the system in the nuclear industry, Arvia have also proven the technology, at smaller scale, in a number of different sectors in the water and wastewater treatment industry. As well as the destruction of organics, Arvia has demonstrated that the system has the potential for microbial reduction. Developing the system as a biocide treatment system could open significicant new markets, for example in the control of legionella bacteria. Arvia have already demonstrated its potential to control these bacteria populations. This could be a more significant short term market. However Arvia needs to develop a comprehensive market assessment to optimise the introduction of this technology. Hence Arvia is looking at a PoM SMART award to develop the knowledge required to identify the most promising markets for initial introduction of the technology and to demonstrate the business case for future R&D and investment.

A contaminant is removed from a gas in a method in which the gas is contacted with a solvent for the contaminant, and the resultant solution is contacted with intercalated graphite onto which the contaminant is adsorbed. The solvent will normally comprise water, and may itself be a contaminated liquid. In a preferred method the solvent is in a reservoir with particulate intercalated graphite; the contaminated gas is delivered to the base of the reservoir; and the gas rises in the solvent mobilizing the intercalated graphite in the reservoir.

The apparatus comprises a treatment reservoir defining first and second treatment zones separated by a porous membrane. Carbon-based adsorbent material capable of electrochemical regeneration is provided in said first and second treatment zones. An agitator is operable to distribute the adsorbent in aqueous organic waste liquid contained in the first and second treatment zones. First and second electric current feeders are operably connected to the adsorbent in the first and second treatment zones respectively. A controller operates the electric current feeders to pass an electric current through the adsorbent in the treatment zones in one direction to regenerate the adsorbent in one of the treatment zones and to then reverse the direction of the current applied to the adsorbent to regenerate the adsorbent in the other treatment zone. Further apparatus is described which facilitates aqueous waste water treatment in a continuous manner.

Contaminants are removed from a quantity of contaminated liquid in a treatment reservoir (2,28) containing a carbon based adsorbent material capable of electrochemical regeneration. The adsorbent material is in the form of a bed supported on a plate (6) at the base of the reservoir. The bed is agitated for a period to distribute the adsorbent material in the liquid and adsorb contaminant therefrom. At the end of the period the agitation ceases, and the bed of adsorbent material is allowed to settle. The adsorbent is then regenerated, during or after settlement, by passing an electric current through the bed to release from the adsorbent gaseous products derived from the contaminant, in bubbles rising through the decontaminated liquid in the reservoir. Various methods of regenerating the adsorbent material are disclosed, as are apparatus in which the method can be applied.
