How To Keep Consistent Chlorine Residuals In Small Storage Tank Systems

By Gerry Bulfin

Chemicals used for disinfection react with various contaminants in water and degrade over time, resulting in a loss of disinfection residual.   The loss of disinfectant residuals can set up conditions for serious bacterial growth, as well as increased levels of disinfection byproducts.  

Storage tanks that have aging water without regular replenishment of fresh disinfected water can become stagnant and allow bacteria to grow.   These conditions become worse as ambient temperatures rise.
