A reverse osmosis system is a technological innovation that removes dissolved organic substances from water. This is the reason why RO systems are used in areas where drinking water contains heavy metals, nitrates or other dissolved minerals that may be very difficult to remove by other filtration methods. It makes use of a high quality carbon filters to get rid of chemicals or organic materials that passes through the sediment pre-filter. It is an effective way of removing water and making it safe for drinking.
Although RO systems are quite slower than regular filters, they actually filter more water per day than distillers. They also do not require electricity to operate, unlike some other forms of water purification. But one disadvantage of using this system is the fact that they waste a considerable amount of water during the water purification process. To purify one gallon of water, you may waste about 4 to 5 gallons. However, there are some zero waste RO systems available which force this waste water back into the system and carry out another filtration process.
This step may not give you clean drinking water like the first stage because there is an increased level of pressure and the membrane is expected to work more than normal. It may allow some contaminants to pass through the system which may not have been possible on a normal filtration method. However, there is a better alternative to prevent too much waste of water using a permeate pump. This method will reduce the waste of water by up to 85%.
Types of Reverse Osmosis Membranes
There are two main types of RO membranes: the Cellulose Tricetate membrane and the Thin Film composite membrane. The major differences between these two are chlorine tolerance and filtration ability. The CTA is prone to bacterial infection but is more tolerant to chlorine and traps about 95% of the contaminants in water. However, the TFC membrane has better filtration capacity since it rejects about 98% of contaminants and does not easily get caught by organic fouling. But it doesn’t function or treat water populated by chlorine. That is why there are brine water, saline water, and brackish water membranes available for municipal, industrial and marine desalinization.
The best quality system removes about 99% of water contaminants with the recently improved technology. It effectively removes microorganisms, harmful chemicals, metals and dissolved solids from water. They are designed with the most sophisticated components to provide a strong and effective filtration mechanism to provide clean and safe drinking water.
The best quality reverse osmosis systems have great filters which can easily trap molecules that may be harmful to the body when they are left in the drinking water. But they don’t just filter everything out of water. There are some nutrients and minerals needed in the water for man’s good health. Some minerals like calcium, potassium and magnesium and very vital minerals the body needs. Some poor quality RO systems filter everything out of the water without leaving a trace of the minerals. The best quality RO systems have a method of re-introducing these minerals into the water, thereby giving you a high quality clean drinking water while providing the necessary minerals for your overall health.
If you want to buy a best quality reverse osmosis system, do not fail to look at the brand and the features of the product. You can decide to go for a countertop system or and under-the-sink system. The choice you make will depend on your need. If you want a portable system, a countertop RO system will be ideal. In the end, try to buy a system that will provide exceptional purification to keep your family free from bacterial and virus infested water.
