    algae control in drinking water plants

    By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the demand of chemicals or filtration and in turn creating problems with THM (trihalomethane) formation. Other common issues are growth of toxin and geosmin producing cyanobacteria (blue-green algae) within the intake reservoir or dam. These molecules give the water an unpleasant `earthy ` taste.

    Algae monitoring of drinking water reservoir -

    Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor the algae concentrations and possible toxic blue green algae blooms. During almost 4 months the ALGcontrol measured the total chlorophyll and cyano chlorophyll concentrations of the water reservoir. In order to be able to compare these results, second off-line controls were carried out using the ISO 10260 chlorophyll-a quantification (extraction into ethanol, spectrophotometric detection at 665 and 750 nm). The results of the off-line standard lab method show a good correlation with the measurements of the ALGcontrol. The good correlation can be verified as well at high as at low concentrations of total chlorophyll.
