The objective of this study was to establish an operational strategy to predict, quantify and overcome
the problem related to algae and metabolites on various water treatment plants treating surface waters.
The outcomes of this work included:
an operational strategy to control and minimize algae growth problem;
recommendations to optimize and upgrade treatment technologies to remove algae and associated
micro-pollutants; and,
improvements in customer satisfaction (taste and odor).
The approach, developed as part of this project, was implemented through different case studies on
resources and associated water treatment works in France, the United Kingdom, and the U.S. Results from a survey
performed in France on more than 30 production sites are presented. For each aspect of the global
methodology, the different actions considered were as follows:
understanding of the phenomena occurring in the catchments/resource including land use assessment,
identification of sources of pollution and set-up of actions such as reduction of nutrient (N,P),
development of buffering zones in land/water interfaces, aeration, and phosphorous sequestering;
implementation of sampling stations and monitoring programs to develop site-specific
methodologies for short term algae control and elaboration of a decision-making flow chart
procedure, some emerging sensors (fluoroprobes) were assessed for the on-line monitoring of
algae, chlorophyll a and cyanobacteria; and,
assessment of the Best Available Technologies for Algae removal and their efficiencies for
removal of the micro-pollutants associated (algal toxins, Geosmin and MIB). Includes 24 references, tables, figures.
