  • Kinetic study of adsorption and photo-decolorization of Reactive Red 198 on TiO2 surface 
    Dutta, S.; Parsons, Simon A.; Bhattacharjee, C.; Jarvis, Peter; Datta, S.; Bandyopadhyay, S. (Elsevier, 2009-12-15)
    Recycling and reuse of wastewater after purification will reduce the environmental pollution as well as fulfill the increasing demand of water. Adsorption-based water treatment process is very popular for dye-house wastewater ...
  • Kinetics of Struvite Precipitation: Effect of the Magnesium Dose on Induction Times and Precipitation Rates 
    Le Corre, Kristell S.; Valsami-Jones, Eugenia; Hobbs, Phil; Parsons, Simon A. (Taylor & Francis, 2007-12-31)
    The presence of white deposits in specific areas of wastewater treatment plants is generally the consequence of the spontaneous formation of a mineral called struvite. Struvite forms when the levels of phosphate, ammonium ...
  • Magnetic ion-exchange resin treatment: Impact of water type and resin use 
    Mergen, Maxime Rodolphe Denis; Jefferson, Bruce; Parsons, Simon A.; Jarvis, Peter (Elsevier Science B.V., Amsterdam., 2008-04-30)
    Three raw waters of fundamentally different natural organic matter (NOM) character were treated by magnetic resin using a bench-scale method designed to mimic how the resin is used in continuous operation. Increasing ...
  • Measuring Floc Structural Characteristics 
    Jarvis, Peter; Jefferson, Bruce; Parsons, Simon A. (Springer, 2005-05)
    A review is presented of a range of techniques for the structural characterisation of flocs. Flocs may be considered as highly porous aggregates composed of smaller primary particles. The irregular size and shape of flocs ...
  • Mechanical sludge disintegration for the production of carbon source for biological nutrient removal. 
    Kampas, Pantelis; Parsons, Simon A.; Pearce, P.; Ledoux, S.; Vale, P.; Churchley, J.; Cartmell, Elise (Elsevier, 2007-04)
    The primary driver for a successful biological nutrient removal is the availability of suitable carbon source, mainly in the form of volatile fatty acids (VFA). Several methods have been examined to increase the amount of ...
  • A model for predicting dissolved organic carbon distribution in a reservoir water using fluorescence spectroscopy 
    Goslan, Emma Harriet; Voros, Sandrine; Banks, Jenny; Wilson, Derek; Hillis, Peter; Campbell, Andrew T.; Parsons, Simon A. (Elsevier Science B.V., Amsterdam., 2004-02-01)
    A number of water treatment works (WTW) in the north of England (UK) have experienced problems in reducing the dissolved organic carbon (DOC) present in the water to a sufficiently low level. The problems are experienced ...
  • Modeling bromate formation during ozonation 
    Jarvis, Peter; Parsons, Simon A.; Smith, Rosie (Taylor & Francis, 2007-12-31)
    Bromate formation has been identified as a significant barrier in the application of ozone during water treatment for water sources that contain high levels of bromide. Bromate has been identified as a possible human ...
  • Natural organic matter - The relationship between character and treatability 
    Parsons, Simon A.; Jefferson, Bruce; Goslan, Emma Harriet; Jarvis, Peter; Fearing, David Andrew (Iwa Publishing, 2004-12-31)
    The characterisation and treatment of natural organic matter are becoming more important to the water utilities in the UK and around the world. This paper looks at the relationship between bulk and fractionated organic ...
  • Phosphorus Recovery from Wastewater by Struvite Crystallization: A Review 
    Le Corre, Kristell S.; Valsami-Jones, Eugenia; Hobbs, Phil; Parsons, Simon A. (Taylor & Francis, 2009-12-31)
    The present review provides an understanding of principles of struvite crystallization and examines the techniques and processes experimented to date by researchers at laboratory, pilot, and fullscale to maximize phosphorus ...
  • The practical application of fractal dimension in water treatment practice-the impact of polymer dosing 
    Jarvis, Peter; Parsons, Simon A.; Henderson, Rita Kay; Nixson, Nicholas; Jefferson, Bruce (Taylor & Francis Inc., 2008-07-01)
    The application of floc fractal dimension has been investigated in this work to determine if this parameter can have operational significance in water treatment. Natural organic matter suspensions were coagulated with ...
  • Quantifying the performance of a hybrid anion exchanger/adsorbent for phosphorus removal using mass spectrometry coupled with batch kinetic trials 
    Martin, Benjamin D.; De Kock, Lueta-Ann; Gallot, Maxime; Guery, Elodie; Stanowski, Sylvain; MacAdam, Jitka; McAdam, Ewan J.; Parsons, Simon A.; Jefferson, Bruce (Taylor and Francis, 2017-07-20)
    Increasingly stricter phosphorus discharge limits represent a significant challenge for the wastewater industry. Hybrid media comprising anionic exchange resins with dispersions of hydrated ferric oxide nanoparticles have ...
  • A review of floc strength and breakage 
    Jarvis, Peter; Jefferson, Bruce; Gregory, J.; Parsons, Simon A. (Elsevier, 2005-09)
    The main focus of the paper is to review current understanding of floc structure and strength. This has been done by reviewing current theoretical understanding of floc growth and breakage and an analysis of different ...
  • Struvite crystallisation and recovery using a stainless steel structure as a seed material. 
    Le Corre, Kristell S.; Valsami-Jones, Eugenia; Hobbs, Phil; Jefferson, Bruce; Parsons, Simon A. (Elsevier Science B.V., Amsterdam., 2007-06-01)
    A metallic system acting as a seed substrate has been designed and developed in order to assess its efficiency in recovering phosphorus as struvite. The device, consisting of two concentric stainless steel meshes, was ...
