ALGAL TOXIN REMOVAL FROM WATER
J Hart, P Scott and P R Carlile
Identification of processes capable of removing algal toxins from drinking water.
Optimisation of processes for removing algal toxins from drinking water.
To identify and develop processes suitable for the removal of algal toxins and to provide a basis for estimating potential water treatment costs.
Blooms of blue-green algae can give rise to the production of toxins that may contaminate freshwaters used as sources for potable water. There is concern that these materials are not effectively removed by conventional water treatment processes and that they may enter supply.
The laboratory tests have shown that advanced water treatment processes can be used to remove microcystin-LR from a lowland derived water. The conclusions for each process are as follows:
There are no recommendations at this stage of the project as the full evaluation of advanced water treatment processes has not been completed, and further investigations are underway. The final report for the project is due for completion in March 1993.
VI RESUME OF CONTENTS
