A safe, simple and quick method
of solving the nuisance algae problem in
water supply reservoirs
The traditional method of algae control has been the use of copper sulfate, commonly called “bluestone.” Copper sulfate, in both crystalline and liquid forms, has been used as an algicide in water supply reservoirs for years, having good to mixed results.
Often its usage is labor-intensive and therefore very costly. Additionally, large quantities of copper sulfate are usually required to achieve a concentration of dissolved CuSO4 • 5H20 sufficient to control algae. Long-term control is nearly impossible as the copper quickly settles to the bottom, often requiring further applications. Chem-A-Co, Inc. manufactures a fully dissolving copper-sulfate product which offers significant improvements over other copper-based algicides. This product – SCI-62®, a liquid copper treatment – has many amazing advantages over bluestone and other liquid algicides. SCI-62® self-disperses both horizontally and vertically throughout the water column. Copper concentrations are easy to measure, providing the correct treatment rates for targeted species of algae and bacteria. Pre-treatment is now possible because SCI-62® can be applied before algae can start to bloom. Long-term control is now possible without constant application, thus relieving concerns of the contamination of sediments due to the extended use of copper. SCI-62® is registered as an algicide/bactericide with the U.S. EPA, and certified to ANSI-NSF Standard 60 as a drinking water additive. Pre-treatment with SCI-62® in potable reservoirs will:
- Reduce THM precursors
- Shorten filter runs by reducing turbidity caused by organics
- Reduce planktonic algae and bacteria that cause bad taste and odors
- Insure long-term control without over-treatment
SCI-62® is an environmentally-responsible water treatment that is non-toxic to humans and fish when used as directed. SCI-62® meets and exceeds the expectations of water operators who are trying to meet today’s ever-increasing water restrictions and legal requirements.
