KNOW ABOUT REVERSE OSMOSIS PRINCIPLES
WHY REVERSE OSMOSIS DRINKING WATER ?
There are many, many water borne contaminants, viruses, bacteria and amoeba that still make it through today's purportedly high-tech water source processing, these include:
TURBIDITY:
This has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
REVERSE OSMOSIS:
Reverse Osmosis requires external pressure to reverse natural osmotic flow. As pressure is applied to the saline solution, water flows from a more concentrated saline solution through the semipermeable membrane. (See figure 2)
REVERSE OSMOSIS MEMBRANE ELEMENTS:
A reverse osmosis membrane has a thin microporous surface that rejects impurities, but allows water to pass through.
The membrane rejects bacteria, pyrogens, and 85%-995% of inorganic solids. Polyvalent ions are rejected easier than monovalent ions. Organic solids with molecular weight greater than 300 are rejected by the membrane, but dissolved gases pass through.
Reverse osmosis is a percent rejection technology. The purity of the product water depends on the purity of the inlet water. The purity of reverse osmosis product water is much higher than the purity of the feed water. (See figure 3)
MAIN TYPES OF REVERSE OSMOSIS SYSTEMS:
- - Reverse Osmosis for Home and Office use
- - Reverse Osmosis for Commercial Applications
- - Reverse Osmosis for Industrial Applications
- - Reverse Osmosis for Seawater Desalination (Portable Based)
- - Reverse Osmosis for Seawater Desalination (Marine Based)
- - Reverse Osmosis for Seawater Desalination (Land Based)
