The Science of Applying UV for Water Treatment
All living organisms contain DNA (Deoxyribonucleic Acid). DNA provides the mechanism  for all functions needed to sustain life. AquaBest disinfection systems emit UV light that  penetrates the outer cell membrane of microorganisms, passes through the cell body, reaches the DNA and alters the genetic material. The microorganism is thereby destroyed in a non-chemical manner and is unable to reproduce.When organisms absorb UV light in the range of 200-300nm, DNA and RNA molecules absorb the UV. The DNA molecule contains all the genetic information needed for replication. UV absorption causes disruption of the nucleic material of the double helix strands. This prevents replication, which is lethal to the cell. The absorption of UV radiation at 254nm causes the formation of dimers along the DNA strands. Dimers are A_A (adenine - adenine), GG (guanine -guanine), T-T (thymine-thymine) compounds as opposed to the normal formation of A-T-G-C- etc.

If the dosage is not optimized, then complete inhibition of replication WILL NOT occur. On the other hand, an insufficient UV dosage may cause limited damage to the DNA, which then can, under favorable conditions, repair using repair enzymes. That's why it is extremely critical to impart the OPTIMUM UV dosage to prevent repair. While bacteria have built-in repair enzymes, viruses do not. Therefore, they have to rely on the enzymes of the host cell.
TOC Reduction
The Science of Applying UV for Water Treatment
In ultrapure water applications, AquaBest UV systems are used for the effective reduction of organics, commonly referred to as TOC otherwise known as Total Oxidizable Carbon.

UV light in a 185nm wavelength promotes the formation of free radicals, leading to the oxidation of organics into CO2 and H2O and is more powerful than the 254nm used in disinfection applications. Efficient in high volume ultrapure, waste or reclaim applications, AquaBest TOC systems have the flexibility to serve indoor or outdoor installations . AquaBest ultraviolet systems are a safe and effective alternative for TOC destruction, providing low maintenance costs and utilizing non-toxic UV light with minimal byproducts.
