The Associated Press’ investigation also indicates that watersheds and other surface water sources also are contaminated. Pharmaceuticals in waterways have been found to damage wildlife across the US. Notably, male fish are being feminized, creating egg yolk proteins, a process usually restricted to females. Benjamin H. Grumbles, assistant administrator for water at the U.S. Environmental […]

In this posting we are going to discuss the ozonation of sump water. Sump water often is a good environment for the growth of micro organisms. In some cases the biological growth is significant and can create odors and potential blockage of the sump pump. To prevent this problem, many facilities will add a biocide […]

In this posting we will discuss an application where a farmer employed a Spartan Environmental Technologies ozone generator, a model AE13M, for use in an irrigation system to control biological growth. The farmer had been using hypochlorite solution for this application. Our client was not satisfied with the hypochlorite solution due to rising costs and […]

In this posting we are going to talk about “good†and “bad†ozone in the environment. The discussion of bad ozone comes from the US EPA website. The discussion of the good ozone comes from the NASA website. Ground-level or “bad” ozone is not emitted directly into the air, but is created by chemical reactions […]

This posting is our third in a series discussing the use of ultra sonic systems for the control of algae. In this note we will ultra sound in the context of a total water management system. As noted in the previous note we discussed how ultra sound can damage the hard outer cell wall of […]

In this posting we will talk a little more about ultrasonic algae control. The discovery that ultrasonic waves in water kill algae was made over sixty years ago in submarine sonar experiments. It took some before this observation was applied to the control of algae in ponds, pools and other water bodies. Effective ultrasonic algae […]

In our postings up to this point we have focused on on oxidation technologies. Spartan also offer ultrasonic algae control products. Our partner in this area is Algae Control US. The following information on teh use of ultrasonics for biofilm control was provided by the Vice President for Engineering of Algae Control US, George Hutchinson. […]

In this posting we will discuss measurement of dissolved ozone. Knowing dissolved ozone concentration is important in a variety of situation, most especially in water disinfection. The ozone residual is critical for calculating the CT value as we have discussed in previous postings. CT in turn is the key parameter for determining pathogen inactivation. In […]

In this post we would like to talk about pilot and lab testing of ozone water treatment and advanced oxidation applications. Typically, pilot and lab tests are conducted to first see if ozone or other advanced oxidation processes will address the water treatment objectives, or to assess the economics of using ozone or other advanced […]
