| Reverse Osmosis household drinking water purification systems are commonly used for improving water for drinking and cooking.
Such systems typically include a number of steps:
A sediment filter to trap particles including rust and calcium carbonate
optionally a second sediment filter with smaller pores.
An activated carbon filter to trap organic chemicals, and chlorine which will attack and degrade TFC reverse osmosis membranes
A reverse osmosis (RO) filter which is a thin film composite membrane (TFM or TFC)
Optionally a second carbon filter to capture those chemicals not removed by the RO membrane.
Optionally an ultra-violet lamp is used for disinfection of any microbes that may escape filtering by the reverse osmosis membrane. |
