Comparison of the disinfection by-product formation potential of treated waters exposed to chlorine and monochloramine

Bougeard, M. M.; Goslan, Emma Harriet; Jefferson, Bruce; Parsons, Simon A. (Elsevier, 2010-02)

The formation of disinfection by-products (DBPs) from chlorination and monochloramination of treated drinking waters was determined. Samples were collected after treatment at 11 water treatment works but before exposure ...
Computational Fluid Dynamics Modelling of Flocculation in Water Treatment: A Review

Bridgeman, J.; Jefferson, Bruce; Parsons, Simon A. (2009-06-30)

The principal focus of this paper is to present a critical review of current approaches to modelling the inter-related hydrodynamic, physical and chemical processes involved in the flocculation of water using Computational ...
Fouling control of a membrane coupled photocatalytic process treating greywater

Pidou, Marc; Parsons, Simon A.; Raymond, Gaelle; Jeffrey, Paul; Stephenson, Tom; Jefferson, Bruce (Elsevier Science B.V., Amsterdam., 2009-09-01)

Fouling in membrane coupled photocatalytic reactors was investigated in the case of greywater treatment by establishing the link between product type, dose, irradiation time and fouling rates in a cross flow membrane ...
The impact of barley straw conditioning on the inhibition of Scenedesmus using chemostats

Murray, Daniel; Parsons, Simon A.; Jarvis, Peter; Jefferson, Bruce (Elsevier Science B.V., Amsterdam., 2010-03-31)

The current paper investigates the role of barley straw conditioning on inhibiting the alga Scenedesmus. Fresh, pre-rotted and white rot fungi (WRF) augmented straw was tested in a series of chemostat experiments over ...
Impact of calcium on struvite crystal size, shape and purity.

Le Corre, Kristell S.; Valsami-Jones, Eugenia; Hobbs, Phil; Parsons, Simon A. (Elsevier, 2005-10-01)

Struvite precipitation occurs spontaneously in wastewater treatment plants under conditions that are influenced by many factors including concentration of , and ions, pH, temperature and mixing energy. These parameters ...
The impact of differing cell and algogenic organic matter (AOM) characteristics on the coagulation and flotation of algae

Henderson, Rita Kay; Parsons, Simon A.; Jefferson, Bruce (Elsevier, 2010-06)

The aim of this study was to compare the coagulation and flotation of different algae species with varying morphology and algogenic organic matter (AOM) composition in order to link physical and chemical algae characteristics ...
Impact of Reactor Operation on Success of Struvite Precipitation from Synthetic Liquors

Le Corre, Kristell S.; Valsami-Jones, Eugenia; Hobbs, Phil; Parsons, Simon A. (Taylor & Francis, 2007-11-30)

A pilot scale reactor was designed and developed to study struvite crystallisation principles. The present work focuses on the possible impact of the reactor's operating parameters on struvite characteristics, and evaluates ...
Incorporating biodegradation and advanced oxidation processes in the treatment of spent metalworking fluids

MacAdam, Jitka; Ozgencil, Haci; Autin, Olivier; Pidou, Marc; Temple, Clive; Parsons, Simon A.; Jefferson, Bruce (Taylor & Francis, 2012-04-27)

The treatment of spent metalworking fluids (MWFs) is difficult due to their complex and variable composition. Small businesses often struggle to meet increasingly stringent legislation and rising costs as they need to treat ...
Influence of granular activated carbon media properties on natural organic matter and disinfection by-product precursor removal from drinking water

Golea, D. M.; Jarvis, Peter; Jefferson, Bruce; Moore, Graeme; Sutherland, S.; Parsons, Simon A.; Judd, Simon J. (Elsevier / IWA, 2020-02-15)

Operational and financial constraints challenge effective removal of natural organic matter (NOM), and specifically disinfection by-product (DBP) precursors, at remote and/or small sites. Granular activated carbon (GAC) ...
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)
