Drinking Water
As demand for water continues to increase, Water Utilities are challenged more than ever to provide affordable, quality water while reducing the environmental impact of chemical usage. Europe has banned the use of herbicides. In the US, there is increase pressure to limit or ban entirely the amount of copper based herbicides.
Since 2002, the key personnel at EnviroSonic Ltd. have been involved in developing an understanding of the reaction process of ultrasonics on alga cells and its applications in water treatment processes. Based on this research and practical experience, the EnviroSonic product line has been developed. These units are capable of controlling algae up to a range of 1000 feet for colonial green algae, and possibly twice that for cyanobacteria.
In addition to these open water units, there are anti-fouling systems for use in tanks, clarifiers, concrete basins and pipe works. Combinations of the various models in key locations will keep algae and biofilm growth under control without the heavy addition of chemicals.
Every site is different. Water conditions, climate, shape, and dimensions are all factors for determining the model and number of ultrasonic units needed for optimum performance. In order to provide you with the best solution, the following information will be needed.
- Dimensions
- Shape/Layout
- Flow Rate
- Water Usage (irrigation, potable water reservoir, wastewater lagoon, cooling towers, retention basins, etc)
- Species of algae/bacteria if known
- Location - Many times a pond or water system can be viewed with satellite imagery for sizing and unit positioning. The nearest address or a GPS type latitude/longitude is helpful.
