Data from real world case studies will be presented, illustrating that a formulation of liquid copper yields superior results.
(PRWEB) April 07, 2017
Frequency and severity of Harmful Algae Blooms (HABs) in the California-Nevada region have increased in recent years. These HABs affect plant operations and sometimes force temporary closures of water treatment plants due to severe taste and odor issues or cyanotoxins. Copper-based algaecides have been an important tool for many decades in management of source water. In some cases, copper has been over-used, leading to backlash.
Doctor Hammond will discuss recent advances that have led to more efficient formulations of copper, which have superior performance and have less environmental impact. “Data from real world case studies will be presented, illustrating that a formulation of liquid copper yields superior results, superior pest control, and better cost-effectiveness at lower doses.” states Hammond.
One such product, EarthTec, has been reported by municipalities to reduce taste and odor by directly removing or degrading the compounds responsible, such as geosmin. It delivers a low-dose of copper at only 60 Parts per billion. The use of advanced copper based products such as EarthTec QZ for the treatment and prevention of invasive quagga mussels (Dreissenids) will also be discussed by Dr. Hammond. Both products are approved by the EPA for control of in lakes and open waters. They are also approved for mussel control in pipelines and flowing waters. QZ is one of a select group of products that is both NSF-Certified for drinking water and EPA registered as a molluscicide. It has been in full-scale implementation at water treatment plants throughout the U.S.
Data and case studies from some of these municipalities will be presented at the CA/NV AWWA conference in Anaheim, CA on April,11.
