| Copper Sulfate
Most species of algae can be controlled with very low concentrations of copper sulfate. Copper Sulfate is the most widely used and, in most cases, most economical algae control chemical available. It has been applied directly to both source waters (i.e. lakes, reservoirs) and settling basins in drinking water applications. It can be fed seasonally or in some cases year round. Copper Sulfate can be added at the intake to the reservoir or injected between the raw water source and the treatment plant for thorough dispersal in the system. This uniform and continuous application effectively controls algae blooms in the treatment system.Related taste and odor problems are also alleviated as metabolites from algal cell processes and cell lysis are eliminated. Dry Copper Sulfate is an odorless blue crystal that readily dissolves in water. It is also supplied as a 25% solution product, Liquid Copper Sulfate, 25%.

Copper Sulfate Reduction
EarthTec can be used to replace copper sulfate. Many customers have been using copper sulfate for years to treat unwanted algal blooms in the late spring and throughout the summer. The problem is copper sulfate crystals sink, so much of the copper is wasted and settles to the bottom. It also requires an extensive labor campaign to apply the product. These drawbacks are eliminated with EarthTec. EarthTec can be applied in one location and it will evenly distribute throughout the body of water. All of the product is immediately bioavailable and toxic to algae. EarthTec does not settle out and is not wasted. The residual EarthTec stays in solution to prevent algae regrowth and is only consumed when met with biological demand. Most customers who switch from traditional copper sulfate crystals (25% Cu) to EarthTec (5% Cu) find that they immediately reduce the amount of copper they are adding to the environment.
Algae Control Problems / Taste and Odor
Are you frustrated with yearly complaints from customers about the earthy, musty smell of the water? By proactively monitoring blue-green algae levels and monitoring yearly lake trends we can help you start controlling the algae that releases taste and odor compounds into your source water. We can detect the problem before you start getting complaints and begin using a very low dose of EarthTec to kill the algae that is present and prevent it from turning into a much larger problem. By monitoring the problem we can help your normal taste and odor event become a shorter episode with fewer complaints from your customers.
