Disinfection versus Bioremediation
There is a definitive difference between disinfection and bioremediation. Disinfection is term used in water wells to indicate e.Coli and Coliform free. Disinfection in surface cleaning is to indicate germ free. Bio-remediation is the act of removing biology, namely tens of thousands of types of bacteria.
The most prominent disinfectant is chlorine. The most prominent biocide is hydrogen peroxide. Are they different? Absolutely.
Let’s use a swimming pool as an example. We chlorinate and pH adjust the pool to fight algae and bacteria. We periodically have to SHOCK the pool to get resistant organisms. We also have to brush the pool to remove biological slimes. Also, you have to circulate the water to keep fresh chlorine coming in contact with the organisms. Why do you have to brush the walls? Because organisms form protective films called polysaccharides and they resist chlorine. By brushing the slime, you scratch it to let chlorine in, you also move it to the water where it can be continually oxidized by the chlorine from all angles. Chlorine degrades to chloramines and chlorides. Chlorides themselves become entrained in the inner granular structure of metals and forms corrosion cells.
Peroxide is very different. It penetrates like WD-40, wicks into the bio-films and destroys the DNA of the organism. Peroxide degrades to dissolved oxygen and water.
Peracetic Acid is a fairly new biocide, where peroxide is mixed with a strong acid and acetic acid. The combination of Well-Klean Pre-blend (a strong acid), and WaterSOLV™ BC, a peroxide, both containing acetic acid, for peracetic acid – a higher grade biocide.
