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 ...

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. ...

In this study, a water cooling tower was used as a low-rate biofilm reactor for treating municipal wastewater. The performance of the system was evaluated at three different flow rates. The biofilm reactor gave the best ...

Bactericides were applied to experimental open recirculating cooling-water systems at concentrations found to be effective under laboratory pure-culture conditions. Total aerobic plate counts and bacterial population ...

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 ...

Microbially influenced corrosion (MIC) makes an important contribution to corrosion in various industries. Considerable success has been achieved by the use of biocides. Little information for controlling MIC is, however, ...

The impact of biofilms present in water distribution systems on the microbial quality of potable water is reported in this review. The issues covered include the composition of biofilms, factors governing their formation ...

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, ...

Hydrogen peroxide is used in various applications to prevent, control or decrease bacterial activity in e.g. cooling water, hospitals, recreational waters and the food industry. The aim of the work reported here was to ...
