Reverse osmosis is an effective way of purifying water that is used today. In reverse osmosis, contaminants are eliminated from the water living water in a safe state for drinking and cooking. Reverse osmosis uses a filtration technology whereby the water goes through an osmotic membrane eliminating impurities. The 5 stage reverse osmosis system is more effective than the 3 stage reverse osmosis system.
Differences in application for the 3 stage and the 5 stage application
The systems perform the same functions that are the purification of water for industrial and domestic uses. The 3-stage reverse osmosis is used mostly for technical reasons. A case in point for aquarium owners use this method for the water for their fish. Farmers also use this method for the water in areas where there is a high concentration of saline in the ground; the farmers use the reverse osmosis water to ensure that the plants can grow to maturity riding dehydration caused by the salt.
The 5-stage reverse osmosis water is mostly used for domestic reasons
Differences in Structure in the 3-stage reverse osmosis and the 5 stage reverse osmosis
System structure 3 stage reverse osmosis
Sediment pre-filter /The carbon pre- filter
The sediment pre-filter is to mainly eliminate residue so that the reverse osmosis membrane is not tempered. The carbon used in some systems is also used as an absorption agent for chemicals that bring bad odor to water e.g. chlorine.
The reverse osmosis membrane
The reverse osmosis membrane has tiny pore that allows for water molecules to pass through, using pressure. The layer is responsible for the filtration of dissolved substances from the water.
The post filter
The sole purpose of post-filtration is to refine the water that is already filtered. The refinement of filtered water removes odor or foul taste that in some instances are left in the water after filtration.
System structure 5 stage reverse osmosis
Polypropylene Deposit filter
The purpose of the polypropylene residue filter is filtration of all solids from the water.
Carbon water filter
The carbon filter is charged in most cases. It has a negative charge that attracts contaminants, as contaminants have a positive charge. Therefore, the contaminants get eliminated from the water. The carbon filter also rids of odor and taste.
1 Micron polypropylene water filter
The micron Polypropylene clears minute particles that are of a certain size that is usually after the polypropylene residue filter.
