Jenfitch, based in Walnut Creek, California, has developed a new oxidant that is effective at lower TOC, reducing THM’s and HAA5’s, eliminating T & O (taste and odors), effective at controlling HAB’s (harmful algal blooms), effective at controlling zebra mussels and other shellfish encrustation, effective at improving coagulation & flocculation, eliminating biofilm formation in the distribution system and improving the effectiveness of your primary disinfectant.

Jenfitch’s JC 9450 is one of a series of advanced oxidant using mineral oxychloride technology (MxClyOz) to help improve the removal of pathogens, organic contaminants and inorganic contaminants. JC 9450 is a new and advanced oxidant that generates reactive oxygen species (ROS) and is NSF Standard 60 approved up to 84 mg/l. ROS are chemically reactive chemical species that contain oxygen (i.e. Ozone, Singlet oxygen, hydroxyl radical ion, peroxides, HOCL, OCL, and superoxide). The main advantage of using JC 9450 is its ability to generate hydroxyl radical ion. Hydroxyl radical ions are extremely reactive and immediately removes electrons from any molecule in its path, turning that molecule into a free radical and thus propagating a chain reaction. At low concentrations, it can disinfect and eliminate all pathogens in a water treatment system without creating disinfection by-products. In Figure 1, we compare the oxidizing potential of various oxidizing reagents:

In a study at a 10 mgd water treatment facility in Northern California that was using ozone in front of their filters, we achieved the following results in a 90-day study using a dosage rate of 8-10 mg/l of JC 9450 as a pre-oxidant:

What is not reflected in this data, was the observed improvement of the ozone generators. We were able to lower the output and maintain the same ozone residual of 0.20-.30 mg/l. We observed the biofilm being removed from the settling basin and a sharp improvement in settled water clarity. We also observed a significant reduction in the primary disinfectant (chlorine). During the period of this study, the plant normally experienced 15 more T & O (taste and odor) complaints from August through October. Management did not receive a single complaint even though the 2MIBs and Geosmin were higher than normal.

In another system in Northern California, we feed JC 9450 as a pre-oxidant at 10 mg/l. The plant was averaging between 95 ppb to 130 ppb of TTHM’s in the distribution system. We started feeding 10 mg/l of JC 9450 in front of the flash mixer and 60 days later the recorded TTHM’s were less than 30 ppb. One year later, the recorded TTHM’s for the same location were less than 10 ppb. Management observed that JC 9450 removed the biofilm and any potential HPC (heterotrophic plate count) from their distribution system. They were able to maintain a consist chlorine residual (primary disinfectant) in the most remote and low flow area of their system.

As you can see, JC 9450 ROS can be used in a variety of applications in potable water systems. It is easy to install and use. It has a shelf life of 6 months when stored according to instructions.
