Calcium Hypochlorite

It was more than 90 years ago that Booton, N.J., became the first utility in the nation to use chlorine to purify water. Subsequently the use of chlorinated water became the norm across the country and safe drinking water is something we all take for granted. In that respect, how many people realize how water chlorination affects other aspects of everyday life? To many people, a nice dip in the pool provides recreation and relaxation, and they don’t need to think about the effort that went into the treatment and sanitation that made that pool a safe and clean place for fun. That is left to the professionals and drinking water fundamentals that can be applied to pool water care.

Commercial, Industrial Ultraviolet Systems

In past articles, we discussed the benefits of ultraviolet (UV) disinfection as well as the many available options. In this article, we will focus on the available technologies and provide an overview of how these technologies are being applied in commercial and industrial applications.

For the last 50 years, the majority of UV systems have incorporated what is known as low-pressure standard output lamp technology.

Using this technology, a single 30-inch lamp, which is 40 watts, can provide the average homeowner with a year?s worth of protection for pennies per day.

Using Maintenance Benchmarking Practices to Specify Chlorine Residual Analyzers

We all have been to that meeting where new regulatory standards requiring more stringent guidelines are announced, when it is demanded that the treatment facility be run more efficiently and that it has been decided that automation is inevitable. Of course, there is a limited budget.

Water Quality Deterioration in Distribution Systems

While temperature is acknowledged to be an important factor in water treatment, remarkably little study has been made of the adverse influence of low temperatures on physical treatment process effectiveness. An early study concluded that "there is no preventative or retarding effect on alum floc formation with low raw water temperatures."
