  • carbonate scale formation and control 
    MacAdam, Jitka (Cranfield University, 2005-03)
    Scale formation in domestic appliances is a widespread problem in the UK. This project has focussed on calcium carbonate scale formation in electric showers. A literature survey identified that CaCO; deposition on heated ...
  • Evaluation of the potential for struvite and calcite formation at seven sewage treatment works within the Severn Trent region 
    Wall, F. (2000-09)
    Scale formation on the pipes, pumps and dewatering equipment succeeding anaerobic digesters leads to reduced hydraulic capacity and increased downtime and pumping costs. The increasing use of biological nutrient removal ...
  • Haloacetic acids and other disinfection by-products in UK treated waters : occurence, formation and precursor investigation 
    Bougeard, Cynthia (Cranfield University, 2009-06)
    Disinfection by-products (DBPs) in drinking water are formed when natural organic matter (NOM) that remains after initial treatment reacts with disinfectants, such as chlorine or chloramines. DBPs, which are of health ...
  • Impact of magnetic resin on DOC removal and downstream water treatment processes 
    Mergen, Maxime Rodolphe Denis (Cranfield University, 2008-01)
    Seasonal periods of high rainfall and changes in land management have led to difficulties for UK water companies to remove sufficient natural organic matter (NOM) to stay in compliance with the tightening trihalomethane ...
  • The Impact of Natural Organic Matter on Floc Structure 
    Jarvis, Peter (Cranfield University, 2004-10)
    The removal of natural organic matter (NOM) at water treatment works (WTW) is essential in order to prevent toxic compounds forming during subsequent disinfection. Coagulation and flocculation processes remain ...
  • Investigating the relationship between shear and floe fate using CFD 
    Bridgeman, Jonathan Matthew (2006-11)
    The size, density and strength of floes play a major role in the removal of contaminants from water in physico-chemical treatment processes. The efficiency of the main removal processes is a function of floe size, strength ...
  • Maximising struvite recovery from real wastewater sources 
    Thomas, David J. L. (2007-04)
    Formation of struvite (MgNFLjPCU.ôFfeO) in reactors is proposed to limit struvite problems in sewage treatment works (STW) and offer a method of phosphorus recovery and recycling. Four sites of interest were identified ...
  • Natural organic matter character and reactivity: assessing seasonal variation in a moorland water 
    Goslan, Emma Harriet (Cranfield UniversitySchool of Industrial and Manufacturing Science; School of Water Sciences, 2003-10)
    Natural organic matter (NOM) is described as an intricate mixture of organic compounds that occurs universally in ground and surface waters. After treatment for potable use, there is NOM remaining in the water that reacts ...
  • Natural organic matter coagulation 
    Sharp, Emma (Cranfield University, 2005-10)
    The removal of natural organic matter (NOM) is one of the main challenges facing water utilities in both the UK and the US. As a consequence of changes in land management and an increased carbon loss from solids, a greater ...
  • Novel treatment options for coagulant and potable sludge 
    Murray, C. A. (Cranfield University, 2005-10)
    increases in coagulant required to remove sufficient quantities of natural organic matter (NOM) to ensure compliance with trihalomethane (THM) regulations lead to an increase in the volume of potable sludge generated. ...
  • Optimisation and effects of coagulant type, pH and ozonation on clarification for automatic coagulation control 
    Marshall, N. I. (1998-09-11)
    Four phases of studies were carried out at Burham Water Supply Works in Kent. Firstly jar testing was used to compare and evaluate the performance of five coagulants. The coagulants tested were Polyaluminium Chlorides ...
  • The potential of barley straw as an algal and cyanobacterial growth control 
    Murray, Daniel (Cranfield University, 2009)
    Algal and cyanobacterial1 blooms are increasingly becoming a problem to water utilities in the UK and around the world. Conditions such as increasing eutrophication and poor management of water bodies are consequently ...
  • Potential of ultrasound treatment for sludge reduction 
    Minervini, Davide (Cranfield University, 2008-09)
    The potential of ultrasound treatment for sludge reduction during the activated sludge process was assessed. Batch and dynamic disintegration studies were completed using an activated sludge pilot-scale plant fed with ...
  • Process modelling of the MBBR / AS hybrid process 
    Berry, Nicholas D. (2000-10)
    With the UK water companies under increasing financial and environmental pressures they are having to look for innovative options to provide lower capital and operational cost solutions to asset management in order to ...
  • Process options for the treatment of humic rich waters 
    Fearing, David Andrew (Cranfield UniversitySchool of Industrial and Manufacturing Science; School of Water Sciences, 2004-04)
    Seasonal periods of high rainfall have led to difficulties in removing sufficient natural organic matter (NOM) to meet trihalomethane (THM) standards, and hence better or alternative treatments are required. Typically ...
  • Removal and recovery of phosphorus from municipal wastewaters using a ferric nanoparticle adsorbent 
    Martin, Benjamin David (Cranfield University, 2010-11)
    Phosphorus is removed from wastewater streams to prevent the ecologically harmful effects of eutrophication in receiving natural systems. Current chemical and biological techniques for removing phosphorus from wastewater ...
  • The role of advanced oxidation processes in drinking water treatment 
    Philippe, Karine K. (Cranfield University, 2010-05)
    Removal of natural organic matter (NOM) is an ever growing challenge for water utilities as many surface waters used for drinking water in the UK exhibit increasing organics levels and it is well known that these organics ...
  • Scale control in heat exchangers 
    Sanchez, G. E. (1998-09)
    Whenever natural water is used in a heat-exchanger, scale deposits tend to build up on heat transfer surfaces. This results mainly from the chemistry associated with the hardness and alkalinity of natural water. To ...
