The Five W’s of Water Purification

More than 50% of the world’s hospital beds are occupied by people battling waterborne illness and disease.

Water purification is a simple and effective way to prevent a hospital visit and protect yourself and your loved ones from the health risks of consuming contaminated water.

Before investing in a water purification system for your home, RV, or other off-grid application, it’s important to understand what water purification is, how it works, and why it matters to you.

 

What is purified water?

Purified water is free of chemicals and other contaminants. Purification involves running water through a specially designed system before it touches your glass. Today’s consumers can choose from a variety of purification methods: reverse osmosis (RO), carbon filtration, and UV-LED disinfection are just a few examples. However, each of these water purification technologies have specific benefits and drawbacks you’ll want to familiarize yourself with.

 

Why should you purify water?

Contrary to popular belief, the way that water looks, smells, and even tastes is an unreliable indicator of quality or drinkability. Because microbial pathogens such as bacteria, viruses, and protozoa are invisible to the naked eye, they will often go undetected without the help of a water purification system.

Left untreated, these microbes will begin to rapidly reproduce and, if consumed, overwhelm your immune system’s ability to fight back. This then opens the door to waterborne illness and disease.

 

Who should purify water?

In short: everyone. Because we are in the midst of a global freshwater crisis, third world countries and developed nations alike alike need to be aware of the threats posed by potential contaminants. Increasingly, urban centres including New York, Vancouver, and Paris are using ultraviolet (UV) water purification, offering residents peace of mind their residential drinking water is safe to consume. That said, the greatest assurance comes when water is purified at the point of use—in this case, immediately before drinking.  

 

Where should you purify water?

Whether you’re on the road, at home, or at work, if you’re drinking water, you should always consider where your water is coming from and take measures to keep that water as safe and clean as possible.

 

When should you purify water?

Water purification is highly recommended whenever you are concerned with or questioning water quality. Typically, most developed nations have governing bodies who regulate, test, and monitor municipal water sources; however, there are still cases when potability may compromised:

 

  • Water in the wild. Lakes, streams, and rivers are at risk of contamination from polluted agricultural or other runoffs. These natural sources may also be prime breeding grounds for bacteria and viruses.

  • Campground and RV hookups. When traveling, you’re often forced to rely on water sources of unknown origin or quality. Water purification offers added protection when filling your holding tank.

  • Boil-water advisories. These public health advisories issued by government or local health authorities signal a potential or confirmed contamination issue. If a boil-water advisory is issued in your area, make sure to follow the recommendations.

  • Foreign countries. Living like a local need not involve sipping unfiltered water, particularly in countries with known water safety issues. Often, water in foreign countries is not suitable for visitors

  • After natural disaster strikes. Floods, hurricanes, earthquakes, tornadoes… all of these have the potential to compromise your home’s tap water. Even a power outage can slow water pressure to the point pathogens and other microorganisms start to take shelter.


At Acuva, our hope and future vision is a world where everyone has access to safe drinking water. Advancements in technology, accessibility, affordability, and awareness help move us closer to realizing this goal.

What’s the Best Way to Purify Drinking Water?

Right now we are in the midst of a clean water crisis. Although 70 per cent of the earth’s surface is water, only 2.5 per cent of that is freshwater. And with our global population expected to rise to a staggering 11 billion by 2100, it is essential we turn our attention to making sure the water we do have access to is safe to drink.

A July 2017 report from the World Health Organization and UNICEF revealed that more than 4.2 billion people currently don’t have access to safe water sanitation methods. That’s nearly 60 per cent of world’s population.

As North Americans, we are fortunate to have access to some of the cleanest, safest water on offer. However, even we cannot escape the risk of illness and disease from waterborne pathogens. It is easier than you might think for drinking water to become contaminated at the source, along the pipeline, or inside a “safe” container.

Ultimately, disinfection is key. As technology evolves, so too do the options at our disposal for improving access and availability to potable water.

Here’s a look at what is currently on the market for consumers:

 

Chemical disinfection

Chemical disinfection uses oxidants such as chlorine-based compounds to rapidly react and kill some (but not all) harmful micro-organisms. Adding chlorine has been used as a convenient water disinfection technique for swimming pools and other household applications. While fast and effective, there are significant health and safety concerns. For example, chlorine-based components are corrosive and must be handled with extreme caution and care.

 

Filtration

Filters trap particles in porous material structures, but still allow water to pass through. This technique is effective for removing things like sand and rust, but it cannot address materials that have dissolved into the water. Though relatively inexpensive, the pore size of most filters is too large to trap microorganisms, so they end up passing through into people’s drinking water. They also require regular replacement, making them a high maintenance approach with only moderate effectiveness.

 

Reverse osmosis (RO)

Membranes, such as those used in reverse osmosis (RO) systems, are also considered filters. RO systems are a more effective alternative for removing microorganisms, but tend to be difficult to install, consume a lot of energy,  and have been found to waste up to 70 per cent of water post-treatment. Unfortunately, RO systems also strip water of its healthy minerals, taking the good with the bad.

 

Ultraviolet (UV) disinfection

One of the world’s most effective water treatment technologies, UV disinfection uses short wavelength radiation to deactivate microorganisms by disrupting their DNA. However, this technology is not without its limitations. Typically, UV lamps require replacement annually, along with monthly cleaning and maintenance requirements. Further, because UV lamps contain mercury and cannot be turned on and off (causing them to consume energy even when there is no water flow), their environmental impact has been the subject of much controversy.

 

UV-LED disinfection

Following careful observation of these and other techniques, scientists introduced a revolutionary technology known as UV-LED. With a longer lifespan (10+ years on average), low power requirements, and low maintenance requirements, the characteristics of UV-LEDs produce an optimal disinfection efficiency and is fast becoming the go-to source for water purification.  

It’s no surprise we’re particularly endeared to this form of water purification. In fact, you’ll find it in all of our Acuva purification systems.
