Removal of Nonylphenol Ethoxylates by Water Treatment Processes

Reference: 98/TX/01/5
ISBN: 1 84057 131 4
Published Date: 17/04/2002

Examines the effect, under laboratory conditions, of aeration, chlorination, ozonisation, coagulation and powdered activated carbon on nonylphenol ethoxylates, a class of compounds, that may have oestrogenic properties. The report makes several preliminary conclusions on their removal, but suggests that further experiments under a wider range of conditions may be required.

Effect of Water Treatment Processes on Oestrogenic Chemicals

Reference: 96/DW/05/10
ISBN: 1 84057 006 7
Published Date: 17/04/2002

Preliminary investigation into the effect, under laboratory conditions, of chlorination, coagulation, ozonation and powdered activated carbon (PAC) on a range of chemicals (steroids and nonylphenols) that have demonstrated oestrogenic activity in laboratory assays. Indicates the likely effects of the various treatments but concludes that confirmation, under a wide range of conditions, requires more extensive investigation.

Steroid Concentration in Treated Sewage Effluents and Water Courses

Reference: 98/TX/01/1
ISBN: 1 84057 095 4
Published Date: 17/04/2002

Reviews and discusses the occurrence of steroids and their conjugates in raw and treated waters and the effectiveness of water treatment processes (chlorination, ozone, PAC, coagulation and filtration, aeration) in removing them. Describes the development and validation of analytical techniques for detecting oestrone, 17B- oestradiol and ethynyl oestradiol and gives the results of monitoring them in drinking waters.
