Reverse Osmosis

Reverse osmosis (RO) reduces dissolved or suspended contaminants in water using pressure to push the unfiltered water, or brine, through a semipermeable membrane. The reverse osmosis membrane blocks the contaminants, allowing the clean water or permeate to flow through to the less concentrated side. RO systems are used in homes and industries where high-quality water with low TDS (total dissolved solids) is required.

A reverse osmosis water system removes:

• Fluoride
• Salt
• Sediment
• Minerals
• Chlorine
• Arsenic
• Volatile organic compounds (VOCs)
• Herbicides
• Pesticides
• Many other dissolved solids


UV Water Treatment

A UV water purifier is made up of a chamber that encapsulates the quartz sleeve that protects the UV lamp. The UV lamp contains little beads of mercury that vaporize and fuel the lamp to emit UV radiation. One or two O-rings, held in place by the glad nut (or cap), hold the quartz sleeve to the chamber and keep water from leaking.

UV water purification does not remove contaminants from water. It deactivates 99.99% of microorganisms by altering their DNA so that they cannot reproduce and spread disease. Once the UV light attacks the bacteria, they’re no longer capable of infecting the water supply.

A UV water purifier deactivates:

• Cryptosporidium
• Giardia
• Dysentery bacilli
• Salmonella
• Mycobacterium tuberculosis
• Streptococcus
• E. coli
• Hepatitis B
• Cholera
• Algae
• Fungi
• Some viruses
