water system

Lonza Water Treatment is making enormous strides in treating drinking water in the northeastern United States, as news spreads about the advantages that our Constant Chlor™ feeders and calcium hypochlorite (cal hypo) sanitizers provide over rival chlorine gas and bleach systems.  Our feeders are primarily suited for small to mid-sized municipal water treatment plants.

Lou Finelli, a National Key Account Sales Manager for Lonza’s Municipal Water business, explains that the following are some of the key benefits of our systems:

  • Our “dry chlorine” sanitizers (the briquettes that are used in our feeder systems) are safer to store and handle than rival gaseous and liquid chlorine, and our cal hypo has a long shelf life;  
  • Due to their simpler operation and safer handling, our cal hypo systems require less intense operator training than rival systems;  
  • Lonza’s patented spray feeder technology produces a more reliably consistent level of available chlorine and residual chlorine levels, so the water is treated equally and at recommended levels at all times;  
  • In some cases, state regulations favor our systems over others. 

Mr. Finelli reports that Lonza is the dominant disinfection system provider on Long Island, New York  (Nassau & Suffolk counties), where we have an estimated 250-280 feeders treating 80% of the wells sites. Long Island consists of dozens of Water Districts, each of which may have 5-9 well sites. 

In Connecticut there has been a paradigm shift towards calcium hypochlorite and away from chlorine gas, he adds.  Meriden, Connecticut  --  a small city in the center of the state  --  is installing our Constant Chlor™ systems.  There will be a total of seven Lonza MC4 systems used at different well sites as well as at the city’s main Water treatment plant.  In addition, other Connecticut towns have begun the process of reviewing and designing systems that will employ our feeders and sanitizers.

In Massachusetts, the only accepted calcium hypochlorite method (vetted by the state’s Department of Environmental Protection) is our Constant Chlor™ system.  Given this vital approval, we have sold systems to several state municipalities, including West Springfield, Canton, Whitinsville, Westfield, and West Brookfield, to name a few.

Although chlorine gas (cl2) is the least expensive method of chemical disinfection, the main driver for alternate methods like ours are the safety and risk management issues associated with cl2 gas. And even when competitors offer cal hypo systems, they typically employ the “erosion” method of “feeding” the chemical into the water supply - versus our method of dissolution via spray technology.  Erosion- based systems typically cannot produce or maintain a consistent solution concentration, which results in erratic chlorine residual levels.
