Despite the disadvantages of reverse osmosis, it is an important step for treatment facilities and it has many wonderful industrial applications. It is just that those who promote this system for use in the home often exaggerate about the necessity and the range of contaminants that can be removed.
Whenever you are shopping for anything, education is the best thing to use. In fact, leave your money at home, until you decide what the right choice for your family is. You could make an impulse buy and arrive back at home still wondering if reverse osmosis makes water safe to drink. So, get your facts straight.
There are many disadvantages of reverse osmosis that are not safety issues. There are economical and environmental drawbacks, so I'll cover those briefly, first.
They are expensive to purchase, install and repair. The replacement membranes last a maximum of half a year and cost around $300 to replace. If the membrane becomes damaged, it may have to be replaced earlier. Bacteria can contaminate the membranes if your water sources are contaminated. Disinfection is necessary to prevent this type of contamination.
Most units require electricity to operate, so that is another cost that the homeowner must consider. They create gallons of wastewater that has to be ejected through a process called back flushing. That can be an economic and an environmental issue. What does one do with this wastewater? In most cases, it will end up in your sewer or septic system.
Some of the newer models are an improvement, but the disadvantages of reverse osmosis are still there. They have just added additional steps to address the issue of safety.
You see. The real answer to "does reverse osmosis make water safe to drink" is the following. In very blunt terms, the answer is no. Single stage systems only remove a few of the contaminants that affect your health and safety.
That is why some of the newer systems have added activated carbon granules. This stage removes chemical contaminants that are not removed through reverse osmosis.
Some people are concerned about the disadvantages of reverse osmosis, because of microscopic cysts. People with weak immune systems are advised to purchase a sub-micron filtration purifier for their home. A reverse osmosis system that can remove particles smaller than a micron, that's about the size of a speck of dust on a pinhead, can remove microbial systems.
But, there are other sub-micron filter systems that also remove cysts and cost a lot less. Knowing how reverse osmosis can make water safe to drink should help you choose the right system for your home.
For most of us, the disadvantages of reverse osmosis far outweigh the conceivable benefits.
Reverse osmosis removes impurities from water using a system that forces the water through a membrane with tiny holes. This process has become more popular lately. The effect that it has on the water depends on a couple of things. First, if the water is badly contaminated, it may not be as easy as you think. However, water that looks really bad may not be as contaminated as you would think.
Once the water goes through the membrane it is sent to a storage unit. This is where it stays separate from the water that has not gone through the process. The excess water that did not make it through the membrane goes to a holding tank to be disposed of.
The naturally occurring materials in water may make it taste bad or smell. The water may have an unnatural color. If this is the case, it can be treated. Sometimes the bad water is the result of something that got into the water and contaminated it. The reverse osmosis system is designed to decrease solids that have dissolved in water. It also catches solids that have become trapped in the water and keeps them from going through to the water that is being cleaned.
Many of the elements found in water are naturally occurring elements. One such impurity is antimony. This is found naturally in soil and surface water and is thought that it may come from weathering rocks. Another popular belief is that it could come from industrial plants because it is used in some ceramics, batteries, and fireworks. So this could end up in the water from a number of different sources. Some of the side effects of this element have been known for a number of years. It can decrease your life span, in studies conducted on laboratory animals; it changed the cholesterol blood levels and glucose.
Another impurity that can contaminate the water that we drink is arsenic. Everyone has heard of arsenic but why would it be in water? Arsenic has been found in groundwater and surface water, thought to have been a naturally occurring source and from industrial plants, including smelting, pesticides, and disposal by industrial companies.
The market for household water treatment is increasing constantly. In 2005, an estimate for the use of water treatment products for household use was $2.6 billion dollars. Reverse osmosis was number one in the market and activated carbon filtration was second. Because of the increased fears of biological terrorism, water supplies have been one thing that many people have been thinking of protecting. This may be the reason for the increased interest in treating drinking water.
The best thing to do is have your water tested to determine what type of treatment you need for what purpose you intend to use the water. Different requirements are needed for drinking water, laundry, cooking, or watering plants. This will tell you what type of system you need.
