Ultraviolet TOC Reduction

• In ultra pure water, UV systems are used for the effective reduction of organics. Organics are commonly referred to as TOC (total oxidizable carbon or total organic carbon).
  
• Utilizing a 185nm wavelength the UV energy promotes free radicals in varying degrees of photochemical excitement.
• These hydroxyl (OH-) free radicals break various chemical bonds of organics which in turn produce chain reactions.
• The chain reactions oxidize most organics into CO2 and H2O – the basic building blocks of all organic compounds.

Ultraviolet Disinfection

• Ultraviolet lights used for disinfection emit 254nm waves that penetrate the outer cell membrane of microorganisms.
• The wave passes through the cell body, reaches the DNA and alters the genetic material.
• The microorganisms are thereby destroyed in a non-chemical manner and are unable to reproduce.

Reverse Osmosis Technology
	In water purification systems, hydraulic pressure is applied to the concentrated solution to counteract the osmotic pressure. Pure water is driven from the concentrated solution and collected downstream of the membrane.
Reverse Osmosis Percentage Rejection
	Reverse Osmosis Rejection refers to the ability of a reverse osmosis membrane to reject dissolved solids. The percent rejection describes the difference in TDS between the feed water and the product water.
Reverse Osmosis Percentage Recovery
	Reverse Osmosis Recovery refers to the amount of product water obtained compared to the amount of feed water used.
