• Fingerprinting of commercially available water treatment bactericides in South Africa 

  Brözel, Volker Siegfried; Cloete, Thomas Eugene (Water Research Council, 1991-01)

  Eighteen dominant isolates from water-cooling systems were exposed to 50mg/l of commercially available bactericides, and the kill percentage was determined after 6 h. Application costs of all bactericides giving an average ...
• Immobilisation of Acinetobacter johnsonii cells within alginate beads

• A bacterial population structure study of water cooling systems in South Africa 

  Cloete, Thomas Eugene; Brözel, Volker Siegfried; Pressly, J. (Water Research Council, 1989-01)

  Bacteria forming biofilms occur in all open water cooling systems where they accelerate metallic corrosion, reduce flow rate and decrease heat energy transfer rate. A population structure study of seven systems was conducted. ...
• The reaction of bacterial cultures to oxidising water treatment biocides 

  Pietersen, Belinda; Brözel, Volker Siegfried; Cloete, Thomas Eugene (Water Research Council, 1995-04)

  The possible development of resistance of bacteria found dominant in industrial water systems to the oxidising biocides hypochlorous acid and 3-bromo-1-chloro-5,5-dimethylhydantoin was investigated. Pseudomonas aeruginosa, ...
• Application of Sterikon bioindicators for the determination of bactericide concentrations 

  Cloete, Thomas Eugene; Da Silva, E.; Brözel, Volker Siegfried (Water Research Council, 1993-10)

  Biofouling in industrial water systems is normally prevented by the use of bactericides. However, bactericide programmes often fail owing to the lack of suitable techniques for determining the in situ bactericide concentration ...
• Microbiological survey of open recirculating cooling water systems and their raw water supplies at twelve fossil-fired power stations
