Reverse Osmosis: Is This A Better Way To Purify Water?


In the midst of all the water filtration methods available, many people are curious about reverse osmosis. Is this a better way to purify water?


What is osmosis?

Osmosis the process by which water and other solvents go through a permeable membrane or filter that prevents the passage of dissolved particles or solutes. In osmosis, the lower concentrated solution will filter its solvent into the higher concentrated solution.


What is reverse osmosis?

Using intense pressure, reverse osmosis forces a liquid through a membrane or filter to remove solid particles so that only the pure liquid molecules remain.


Different Applications of Reverse Osmosis


1.  Large scale


• Desalination of water

• Separating chemicals and metals from water supply

• Recycling purposes

Reverse osmosis can treat harmful wastewater that comes from the treatment of metals with chemicals. Clean water is separated to dispose chemicals properly.


2.  Small scale


• Residential under the counter system

A reverse osmosis system can be installed below your sink. It will filter water in stages so that it will become pure. The filtered water is then saved in a storage tank and routed to a separate faucet installed on the countertop.


• Countertop filters

This method can be more convenient since the filtration system is attached to the water supply line. The feed line is then hooked up to your faucet so the water that comes out is filtered.


Disadvantages of Reverse Osmosis


• Waste

Depending on the reverse osmosis system used, anywhere from 2-1/2 to 4 gallons of wastewater is produced for every gallon of purified water obtained.


• Maintenance

For water not to clog the membrane with the matter it removes, it should be monitored for flow rate and changed regularly since it can harbor bacteria and reduce the efficiency of the system.


• Time

Reverse osmosis is a slower type of water filter to use as the water needs to go through the RO process and into the reserve tank before it can be used. Optional pumps are often available to help speed the process.


• Demineralization

The reverse osmosis process removes minerals from the water- even the beneficial ones, so unless you’re employing one of the few reverse osmosis filters that re-mineralizes the water after filtering it, multi-vitamins or supplements may be necessary to replace those minerals.


Reverse osmosis is just one of many methods to purify water. Learn all the facts first before deciding if it’s the best system for you and your family.
