Water Purification

Water Purification Methods

Boiling: It is recommended that one reaches a rolling boil for at least one minute.

Water Distillation catches the condensation produced from boiling water, removing minerals and contaminants in the process.

Reverse Osmosis Filtration System forces water molecules through a semi-permeable membrane, leaving organic contaminants, toxins, bacteria, salts, etc. behind.

Carbon filtering uses Activated Charcoal Water Filter used to remove chlorine, sediment, volatile organic compounds (VOCs), viruses, bacteria, and taste and odor from water.

Ultraviolet Light Filters kill mold, bacterial and viral contaminants, including giardia and cryptosporidium, by passing water through an ultraviolet light source.



Multiple Level Filtration System Ceramic Water Filters are among the stages used in these systems that address contaminants in various stages.

Capacitive deionization



Purification tablets or drops

Pump Purifiers and Gravity Fed Purifiers

Sand Separator

Tata Swach – uses filters made from rice husk ash impregnated with nano silver particles to purify water
