The Wallace & Tiernan legacy in chlorination began 100 years ago with one of the most significant public health advancements of the millennium - the 1913 installation of the first chlorinator in a public drinking water system. It continues today with the latest in gas chlorination, disinfection and chemical dosing systems and packages.
Evoqua’s gas feed and residual monitoring technologies continue to set the benchmark for safe and reliable drinking water purification. Our V2000™ and V10K™ chlorinators, ammoniators and sulfonators are designed with an all-vacuum operation principal, and with V-notch flow technology that provides a wide range of control and high repeatability.
