Understanding the Growthrough Process
Bacteria thrive in damp areas, such as filtration elements inside a water purification system. When the right conditions for growth are present (certain environmental conditions, temperature, pressure, etc.), combined with sufficient nutrients, cells can multiply and penetrate the walls of a water purification system’s filters. This is known as “growthrough”. And since carbon-based filters remove chlorine (which is used to combat bacterial growth) from drinking water, it is that much more imperative that a system’s filter elements are self-sterilizing.
