algae control in drinking water plants - Water and Wastewater - Drinking Water

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.

Control fouling in sand filters

Sand filters can get clogged by fouling of algae and other organisms. An LG Sonic, placed in the sand filter, efficiently controls this fouling, reducing maintenance and improving efficiency.

Control algae in clarifiers

Algae growing in clarifiers can be washed into the filtration area, clogging the filter beds. LG Sonic control the formation of filamentous algae in clarifiers.

Improve coagulation or Flocculation

Ultrasonic sound waves from LG Sonic influences coagulation and flocculation processes in a positive manner, enhancing binding of the particules and increasing floe formation.
