Description
The objective of this study was to establish an operational strategy to predict, quantify and overcomethe 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 associatedmicro-pollutants; and, improvements in customer satisfaction (taste and odor).The approach, developed as part of this project, was implemented through different case studies onresources and associated water treatment works in France, the United Kingdom, and the U.S. Results from a surveyperformed in France on more than 30 production sites are presented. For each aspect of the globalmethodology, 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-specificmethodologies for short term algae control and elaboration of a decision-making flow chartprocedure, some emerging sensors (fluoroprobes) were assessed for the on-line monitoring ofalgae, chlorophyll a and cyanobacteria; and,assessment of the Best Available Technologies for Algae removal and their efficiencies forremoval of the micro-pollutants associated (algal toxins, Geosmin and MIB). Includes 24 references, tables, figures.
