Why Does Water pH Matter?

Why Does Water pH Matter?

There’s been a really cool social experiment done by a housewife in the USA. She tested the pH levels of over 10 of the most popular bottled waters on the retail market, only to reveal that some of these well-known brands contain dangerously high acidity levels. Some of the water had even been specifically marketed to have a higher pH level (indicating that the water is more alkaline, and thus healthier), but when tested, turned out to have a much lower pH than stipulated.

A general rule of thumb is that “The pH of pure water is around 7. In general, water with a pH lower than 6.5 is considered acidic, and with a pH greater than 7 is considered basic. The normal range for pH in surface water systems is 6.5 to 8.5, and the pH range for groundwater systems is between 6 to 8.5”.

But why is it so important to drink pure or alkaline water – as opposed to acidic water?

Inflammation is the cause of all diseases and inflammation is caused by being too acidic. So, if water is too acidic, or for that matter too alkaline, the human body will not allow the water into its cells.

Whoa! So you simply will not absorb water if it is too high or too low in pH! You could be drinking litres upon litres of the incorrect pH water and end up becoming dehydrated, because our bodies simply cannot absorb it!

Also remember that at Aquazania, we re-introduce minute quantities of pharmaceutical grade minerals: Calcium (2,70 parts per million), Magnesium (2,54 parts per million) and Potassium (1,90 parts per million). This produces a natural, sweet-tasting water with additional nutritional properties, and results in a pH of 6,85.

Can I Purify Water By Boiling It?

Can I Purify Water By Boiling It?

Heat destroys all the bad guys, right? If we boil a kettle full of tap water, there’s some sort of reassurance that the water we have boiled is now entirely fit for us to drink- without the worry of getting sick from any latent germs.

Is that really the case though?

If you boil a cup of muddy water – all you’re going to be left with is a (now hot) cup of muddy water. You’re right in saying that the act of boiling water kills microbial bad guys – which are better known as pathogens – but it is never, ever going to remove sediment.

Basically – if you can see something is “off” about the water – boiling it will not resolve that issue.

It’s likely you’ll quicly get rid of things like e-coli etc., but the only way to remove sediment, and essentially “purify” your water, is to put it through some sort of physical filtration.

This could either be by means of filters (granular activated carbon, sediment, rock filters, filter nets or even reverse osmosis filters). The act of physically removing contaminants and sediment, coupled with the boiling of water to remove pathogens, is what will yield the most purified version of that water.

It’s unfortunately not a case of “one or the other” – you need both, if this is your last resort.

However, be cautious when doing this, as not 100% of pathogens will be killed by boiling water.

Your best bet will always be water that has undergone stringent testing and purification processes before even reaching your home.

Water Desalination: What It Is and Why It’s So Scarce

Water Desalination: What It Is and Why It’s So Scarce

We can thank our lucky stars that the drought that had South Africa gripped from 2015 until recently has passed. A topic of conversation that has, however, cropped up – especially since the Western Cape announced it has less than 100 days of potable water left – is the question around water desalination.

I mean, Cape Town is surrounded by an ocean – but there’s nothing to drink – so the logical next step is to start desalinating sea water for the people to drink.

It’s a bit more complicated than that.

“Due to its energy consumption, desalinating sea water is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide.”

There are currently 7 types of water desalination available:

Multi-Stage Flash Distillation

Water is evaporated and separated from sea water through multi-stage flash distillation, which is a series of flash evaporations.

Multiple Effect Distillation

Multiple effect distillation (MED) works through a series of steps called “effects”. Incoming water is sprayed onto vertically or horizontally oriented pipes which are then heated to generate steam. The steam is then used to heat the next batch of incoming sea water, to expel salt.

Vapor Compression Distillation

Vapor compression distillation involves using either a mechanical compressor or a jet stream to compress the vapor present above the liquid. The compressed vapor is then used to provide the heat needed for the evaporation of the rest of the sea water.

Reverse Osmosis

The principal competing process uses membranes to desalt saline water, principally applying reverse osmosis (RO). The RO membrane processes use semi-permeable membranes and applied pressure to preferentially induce water permeation through the membrane while rejecting salts.

Freezing

Freezing involves partially freezing the seawater and removing the ice to then clean and melt back down into now clean water.

Solar Evaporation

Solar evaporation mimics the natural water cycle, in which the sun heats the sea water enough for evaporation to occur.

Electrodialysis / Electrodialysis Reversal

Electrodialysis utilizes electric potential to move the salts through a membrane.

While some of these concepts seem tedious and time consuming, it is mostly the cost that defers people from using this method. The cost of building a functional, large-scale desalination plant can run into the millions, which is likely why South Africa has delayed the implementation of one – especially considering the crisis. Australia still remains the world leader in terms of desalination ability.

Do you think it’s time to invest in a water desalination solution for our country – or should we just learn to better manage and promulgate the resources we are already provided with?

Is Soft Drink Being Kicked To The Curb By Water?

Is Soft Drink Being Kicked To The Curb By Water?

Say the names “Coke” or “Pepsi” to literally anyone in the world, whether they’re from a first world country or a third world state, and they’ll immediately know what you’re talking about. The soft-drink industry has not only grown – it’s exploded over the last few decades; we’re seeing evidence of this in any fast food chain, with their “large” sizes going up as big as 1 litre.

That’s scary. That large drink you order to accompany your meal can sometimes be more than the total of your DAILY recommended sugar intake! You’re consuming in one sitting more than all of what you’re meant to be consuming in an entire 24 hour period – and this is putting our health at major, irreversible risk.

While America is usually the first culprit in any type of over-indulgence, and fingers are pointed at the deteriorating overall health of the people of the country, an article penned by MarketWatch highlights some fantastic news. Experts have said “Americans now drink more bottled water than diet soda or traditional soda. Bottled-water consumption in the U.S. hit 39.3 gallons per capita last year, while carbonated soft drinks fell to 38.5 gallons, marking the first time that soda was knocked off the top spot, according to data from industry tracker Beverage Marketing Corp. But soda is still more expensive, racking up $39.5 billion in retail sales versus $21.3 billion for water, industry research group Euromonitor found. “In 2016, bottled water overtook carbonates to become the leading soft drinks category in off-trade volume terms, an astonishing milestone a decade in the making,” Euromonitor concluded.”

While there are still undeniably too many carbonated soft drinks being consumed than is considered healthy, for the first recorded instance – water is winning! There’s still a far way to go, but we’re heading in the right direction.

The dangers of excessive sugar intake, especially through soft drinks (we tend to overlook calorie and sugar intake when it’s so easily consumed in one drink) are terrifying.

MarketWatch [provided this crippling insight – “Soda and sugary drinks may lead to an estimated 184,000 deaths among adults every year, a 2015 study by researchers at Tufts University published in the American Heart Association’s peer-reviewed journal Circulation. The study analyzed consumption patterns from 611,971 individuals between 1980 and 2010 across 51 countries. Sugar-sweetened beverages consumption may have been responsible for approximately 133,000 deaths from diabetes 45,000 deaths from cardiovascular disease 6,450 deaths from cancer, it concluded.”

 

If that doesn’t shock you into rapidly dropping the soda and replacing it with water, I doubt anything will.

South Africa’s Tap Water Simply Not Up To Scratch

South Africa’s Tap Water Simply Not Up To Scratch

In a video posted by eNCA in May of 2016, reported Theresa Taylor reports on th state of affairs in South Africa’s tap water system.

She opens her discussion with the statement we have somewhat come to pride ourselves on – that “South Africa has some of the best drinking water in the world”. You’ve also heard that, haven’t you?

Well, it’s not entirely true – but also – not entirely false. In a survey conducted in 2001, The United Nations Environment Programme ranked South Africa’s tap water 47th out of a possible 122 countries qualifying for safe drinking water. Yes, this is the top 50, but when you’re scraping by in just less than half way to the bottom – perhaps the accreditation of “…some of the best water” is going a step too far. Did you note the date stamp on that ranking? 16 years ago. Much has changed since then.

Somehow, South African’s have had their blinkers on – living in the land of milk and honey has allowed them to continue believing that we have prime drinking water. In fact, 88% of South African’s still stand firm in this belief to this day.

Their beliefs seem to be inversely proportional to the facts that speak for themselves; South Africa’s water quality has dropped by 8% (down from 88% in 2012 to 80% in 2014) according to the Blue Drop water rating system.

Now it’s not only the fact that undesirable waste may (even microscopically) end up in your water, but whatever medication, pesticides and other contaminants that make their way into this water which is so poorly cleaned, you are inadvertently ingesting it yourself! Unless you are boiling your water and allowing it to chill (which, even then does not entirely remove all the contaminants) – you are putting yourself and your family at a major risk.

UPDATE: The findings of the WHO (World Health Organisation) released, in May of 2018, ranked SA water as some of the cleanest and safest worldwide. You can read the full article here.  “South Africa is among the top six African countries with safely managed drinking water sources, with 93% of the population receiving access to it. Mauritius has the highest number of residents accessing safe water at 100% of the population.”

What’s the safest bet? Ditch the tap water. A the very least, boil your tap water and put it through a carbon filter before drinking. The best possible option is to invest in a water cooler, where you can have uncompromised, premium-quality water on tap all the time.
