To survive, everyone needs water, and clean water for that matter. Contaminated water is a source of many ailments and infections like typhoid and cholera, diseases known to kill their victims if they go untreated.

According to World Health Organization (WHO), more than 150,000 people die of typhoid worldwide every year. The same statistic applies to cholera.

You can avoid drinking contaminated water by buying bottled water from registered and regulated companies, but that would be too expensive.

The easiest and cheapest way to get tasty and high-quality water without spending a fortune is by investing in a reverse osmosis filtration system. It’ll filter and clean your water.

according to watersafetylab water purification blog Avoid drinking straight from the tap, as this could expose you to disease-causing micro-organisms. to read more go to the website clicking here.

The role of RO

RO is a system that contains a filtration membrane that removes or filters contaminants in any water. It is a water purification system that improves water for cooking, drinking and other essential uses.

Ideally, this system pushes contaminated water through a semi-permeable membrane keeping back contaminants and allowing only pure and freshwater. Water goes from the point of high concentration (water with minerals) to the point of low concentration (water without minerals or contaminants).

Tap or rainwater contains a lot of contaminants, both beneficial and harmful to humans. The RO membrane is made of carbon filters that prevent organic chemicals, pesticides, chlorine, and its by-products, herbicides, and other contaminants from passing through.

So, What Exactly Does Reverse Osmosis Remove?

· Unwanted Odors

The last thing you’d want to come across your glass of water is a stinky smell. RO filter removes unwanted odors and improves the taste and quality of your drinking water.

· Chlorine

Almost all Council water contains chlorine. They use it to kill micro-organisms. The RO system filters this chlorine since its molecules are larger than those of water.

· Lead

When ingested or inhaled, lead poses a serious health risk. It is especially dangerous to pregnant women, seniors and kids.

The reverse osmosis filtration system ensures that your family is always protected from the dangers of lead contamination. It effectively removes up to 98% of lead from the water.

· Arsenic

Arsenic is everywhere around us and can be distributed through the air, land and water. And because it’s tasteless and odorless, it can contaminate your water and go undetected.

You’ll only come to realize its presence after your loved ones start suffering from skin discoloration, nausea, vomiting and diarrhea. Long-term exposure to arsenic can actually lead to more chronic symptoms.

RO effectively helps to remove arsenic from water. All you should do is ensure that the system is regularly maintained.

· Volatile Organic Compounds(VOCs)

VOCs are composites that contain carbon which easily dissolves from water into the air. They are found in pesticides, inks, paints, oils and other industrial and commercial products.

When poured or inefficiently discarded, some segments dissolve, leak into the ground and later reach drinking water sources.

Although not all VOCs are harmful, some have toxic effects, especially if exposed to them for a long time. They can cause allergies such as nose irritation, vomiting and dizziness.

Long-term exposure to VOCs can lead to serious health complications such as cancer and damage to the kidney.

Reverse osmosis is capable of removing 70% to 80% of VOCs from drinking water. (source)

· Smaller Molecules

There are some smaller molecules that the carbon membrane is unable to filter. The RO system, in this case, forcefully sends water through a super tight thin-film membrane.

Other contaminants that the second level of filtration gets rid of include asbestos, chloramines, and MTBE from gasoline. MBTE has also increasingly become part of tap water in many municipalities.

RO can go down to filtering the smallest of micro-organisms. The filtration pore size filters giardia and cryptosporidium as well as bacteria and even viruses.

Some filtration systems have pores that are ten times smaller than minor viruses, ensuring that you get the purest water you can think of. However, do not pass any dirty water through the system with the hope of getting clean drinkable water at the end. Use it for tap water.

Final Words

Water treated or filtered by RO is clean, pure and healthy. Investing in this filtration means no more ingesting contaminants. With one, you’ll relive your body the stress of absorbing things that weren’t supposed to be there in the first place.
