Personal profile

As Head of DMU’s Wastewater Treatment Research Group I conduct fundamental and applied research into the chemical treatment of wastewater and in collaboration with microbiologists their use in disinfection. This platform technology has resulted in   a number of international patents pursued by industry and which is now available at industrial scale for exploitation. My work is innovative and recognised both nationally and internationally by the UK Research Assessment Exercise (RAE) with a number of internationally recognised publications and membership of national and international panels for evaluation of research. I have generated over £3million in research grant funding mostly from UK Government funding bodies and collaborate extensively with leading industries which actively support my research group. I have an interdisciplinary research group covering the areas of reactor design, engineering, wastewater analysis, chemistry of catalysis and ion-exchange, characterisation of materials and microbiology.

My research interests are in micro- and macroporous silicate materiaIs (zeolites) developed whilst a post- doctoral Research Fellow at Imperial College, London University and since 1996 in fibrous materials for ion-exchange, catalysis and disinfection.

Externally funded research grants information

Application of a novel material in the remediation of zinc from mine drainage” (2014) funded by The Coal Authority of Great Britain (Project ref: 743). This project grant of £57,000 is for a 3 month trial of a pilot scale treatment system for the removal of zinc, cadmium and lead salts.

“MICROCAT”, (2013-6), funded for £990,916 by the UK Government’s Technology Strategy Board and EPSRC, (TSB Project Ref: Application number: 21337-147263). This project is to develop a wastewater treatment technology with an enhanced performance and smaller footprint. The project focusses on the application of the novel catalyst in the treatment of agricultural wastewaters and hard to treat pesticides in collaboration with a number of industrial partners.

“Biocidal applications of the novel oxidation catalyst”,(2005-8), Ph.D studentship funded by EPSRC to investigate the catalytic potentiation of hydrogen peroxide by the catalyst and its ability to effect a log 5 kill of gram negative and gram positive bacteria, yeast, mycobacteria and spores.

“Heterogeneous catalytic oxidation of contaminated air and water”, (2005-9 ), £ 385,799 from the UK Government Home Office (Project ref: TPU09/05/152 ) to investigate the ability of the novel catalyst in the decontamination of sulphur compounds.

“Novel Catalyst for Low Cost Treatment of Effluent”, (2005-8), a £1,173,100 project funded by the UK Government’s Department of Trade and Industry (DTI, Project Ref: TP/3/WMM/6/I/16801). This project had a number of industrial partners resulting in a successful scale up of catalyst manufacture to meet the needs of industry. A  UK Municipal Water Authority (Severn Trent Water) as end-user resulted in a successful pilot scale demonstration in the degradation of estrogens in wastewater.

“Effluent Treatment Catalyst from Low Value Fleeces”, (2004-7) was funded for £325,336 by the UK Government Department of Food Fisheries and Agriculture (DEFRA, Project Ref:NF0529). This project investigated the sustainable use of coarse wool from highland sheep as a catalyst support.

 “Investigative studies of a novel heterogeneous catalyst for effluent treatment”, (2001-2), an award from The Royal  Society  of  Great Britain for £12,500.This grant funded a NATO post-doctoral research assistant for one year, for characterisation studies on the thickness of the catalyst layer on the fibre surface and the effect of the catalyst impregnation solution to resultant activity.

Published patents

“Antimicrobial Catalyst”, Patent US8513303 (B2) granted 20 th August 2013, EP2185271 (A2) published 19 th May 2010, 

“Selection Method in Production of Fibrous Catalyst”, EP2192980 (A2) published, 9 th June 2010 and US2011098174 (A1) published 28 th April 2011.

“Methods for the Production of a Wool Catalyst”, British Patent Application No. 0716622.6    

Granted 28 th March 2012

“Improvements in the Method for the Production of Fibrous Catalysts”, EP1988995 (A1) |   published 12 th November 2011 and US8410011 (B2) granted 2 nd April 2013.

Case studies

Landfill leachate Working with FCC an international waste recycling company we ran a 4 year pilot scale trial (reactor tank 32L) at Bradgate landfill site in Leicester UK from 2009 to 2014. The catalyst was never replaced as there was no deactivation during this time. 100% of BOD was achieved and up to 80% reduction in overall COD on a waste water varying between 3,000-8,000 mg/L COD. In addition there was excellent removal of methane, H 2 S and hazardous chemical compounds. 75% reduction in TSS, 25% removal in ammonia, and effective removal of trace metals. The treatment system produced no sludge, easy to operate and maintain running under ambient conditions, coped with shock loads and had no contamination of treated feed with catalyst.

Municipal Wastewater A similar pilot scale field trial at Longbridge owned by Severn Trent Water Authority in 2009 resulted in 80-90% removal of the estrogens E1, E2 and EE2 from initial concentrations of 45.67, 7.69 and 0.5ng/L, respectively. Influent was taken after biological treatment but before sand filtration, COD of 40mg/L, TOC of 11mg/L.

Zinc Remediation from Mine Drainage A 60 L reactor tank in a pilot scale treatment system for the removal of zinc from mine drainage water is undergoing a 3 month trial for the Coal Authority. Results so far have shown an average of ~80% removal in zinc from initial concentrations of around 60ppm dissolved zinc with a flow rate of 27.6L/hour. The trial has been running at this level for nearly a month without regeneration. Engineering parameters such as residence time will be varied to explore the system capability.
