Johnson Screens Takes the Lead in Chlorine Alternatives 

New Brighton, June 15, 2023 – Johnson Screens is proud to announce an addition to the Nu-well® well cleaning and development chemical family, a staple of our historic Water Well division. How could this product line get any stronger? With Chlor-Safe, a safe and effective alternative to traditional chlorine (bleach) for disinfecting water wells. 

Like all Nu-Well products used within the well, Chlor-Safe NW-420 is NSF-certified for potable water use (certified by NSF to NSF/ANSI/CAN 60.) Used to disinfect wells without needing pH control, this dry, granular product is simple and has a long shelf life. Chlor-Safe is added to a water container at the surface and dissolved before disbursing to the entire well. This ensures that the chemical is in solution before putting it downhole, allowing the Chlor-Safe to combat bacteria throughout the entire well effectively. 

“We developed Chlor-Safe to dissolve faster than SterileneTM and other chlorine products, so it activates sooner when disinfecting wells and removing bacteria and other contaminating organisms, such as coliform, iron bacteria, E. coli, and other bacteria that cause that tiresome rotten egg smell.”, says Wayne Meyer, Product Manager for Johnson Screens’ Water Wells Business Unit. “Chlor-Safe can also be used to treat near wellbore damage and reduce congestion caused by clays or residual drilling mud.”, he adds. 

 Chlor-Safe is available now through our outstanding network of water well distributors. As with all of our Nu-Well products, please use and dispose of Chlor-Safe NW-420 in accordance with local rules, regulations, and ordinances.
