Using PTH for Domestic water treatment
There are 5 critical issues to know before deciding on a water improving system.
1. What type of water purifying system should I select?
There are many different water treatment systems available. These range from countertop units that get filled by hand to sophisticated – and expensive! – reverse osmosis (RO) systems.
Amongst others, these comprise: Mineral Pots or Brita/Wellness Carafes, etc
Replacement filters and cleaning of units are required from between 2 months to 6 months or so. Treating water through these units is effective but slow, and the water tastes good, but they are essentially only suitable for drinking water.
Another type, such as H2O, attaches to your tap and the unit fits under the counter, but essentially the same criteria apply.
Reverse Osmosis (RO) cleans the water by pushing it through a membrane which removes all the solids, including essential minerals from the water.
The most popular RO system is the 5-stage. This gives you pure water with all impurities and minerals removed
Although this might seem exactly what you want, there is one serious problem: your body, and especially those of growing kids, require these minerals for normal growth. We get these minerals from the water we drink, to be absorbed by the body.
The 6-stage RO system puts these minerals back into the water, while the 7-stage adds oxygen.
RO takes around one hour to create 7,5 litres of purified water, but in the process uses an additional 6 litres of water that simply runs down the drain. If you use 7,5 litres a day for drinking, that would equate to a water wastage of 180 litres of water per month to get clean drinking water. No household in South Africa – or anywhere else, for that matter – can afford such waste.
The RO system does not allow for use much other than drinking and cooking.
The most commonly used descaler functions on electricity and is installed in the main water pipe into your home. It is designed to change the compositional structure of the lime in the water so that it does not cause scale build-up in pipes, elements in kettles and geysers, and appliances.
One millimeter of lime-scale build-up will increase your electricity consumption by 15 to 20 percent for the element to effectively heat your water.
In high-lime content water – which is most of the country – a millimeter of lime-scale can build up in less than 1 month and will continue building, losing you more money on electricity as the element gets older, before collapsing entirely.
The use of a descaler will not reduce the lime-scale already in your pipes and elements, but will prevent further build up. Cleaning or replacing pipes and elements is very costly.
Resin Water Softener (Salt Water Softener)
Hard water contains high levels of dissolved calcium, magnesium, and other mineral salts such as iron. The greater the amount of total dissolved minerals (TDS) in the water, the harder it is. Hard water causes lime-scale build-up in pipes and electrical elements heating water. It is also damaging to all household appliances like washing machines, dishwashers and air-conditioning systems.
A water softener is installed in the main water supply line to your home. There is a manual, semi-automatic and fully automatic system. It must be connected to the electricity supply.
The system needs periodic maintenance. The resin needs to be replaced. It also needs to be regenerated periodically with a brine rinse, at considerable cost.
Because of the many disadvantages associated with resin softeners – health risks, undrinkable water, polluting the soil with the brine rinse-off and others – resin softeners are increasingly being banned world-wide.
The PTH system is a unit that is installed directly into the main water supply of your home.
It functions without electricity supply and is easy to install.
The PTH does not require maintenance.
It has a dual function, acting as both a descaler and water softener. This two-in-one combination results in a better tasting drinking water directly from your tap while it also neutralises the minerals that cause hard water, yet they remain in the water to ensure your good health.
In addition, the system will also over time remove scale and rust from your water pipes and electrical elements, making everything last longer and saving you money.
With PTH-softened water at the turn of a tap, you will need to use less washing powder. When washing your car, those white marks left behind when the water dries can now simply be dusted off. Your garden and plants will thrive with better quality water.
You need clean, healthy water every day. All the above systems will give you better water, in varying degrees depending on the system, than you currently have.
However, what you must aim for is quality water, delivered consistently, at the lowest possible cost, including replacement parts and repairs. All these systems will provide you with drinking water, but what about your plumbing and household appliances and geysers – will they also benefit?
The PTH is the only system that will keep on delivering quality water at enduring value, while protecting your plumbing, geysers and appliances at the same time.
“…I would like to assure you that the Israel PTH system is working well and is doing all that you said it would. With the Progressive Governance Summit held in mid-February 2006 at Didimala Game Lodge with President Thabo Mbeki, Minister Tony Blair and Nelson Mandela amongst other dignitaries and Heads of States, we were required to call the Regional Health Inspectors to ensure the water did not have toxins in it and that the pH levels were satisfactory. The inspectors were so impressed that they said our water is of the purest form.” Jaco Steyn, General Manager, Didimala Game Lodge
“There really is a huge difference in the taste and texture of the water. When I say ‘texture’, I mean when I finish bathing, my skin definitely isn’t so dry; even the bath foam has a richer lather. The water is certainly softer on the skin. Of course, my kettle, clothes, iron and geyser will also last longer without all this lime scale. And then I haven’t even mentioned how good my father-in-law’s whisky now tastes!” Michelle Theron, Gansbaai
3. Supply sufficient for drinking and other daily uses?
The descaler, water softener and PTH system are all connected to the incoming main water pipe. The first two have only one function – drinking water – although due to the release of sodium during the cation exchange process, resin-softened water is unpalatable, while the PTH supplies healthy drinking water, protects pipes, geysers and appliances and improves gardens.
“As you probably know, Stilbaai is known for its above-average ‘brack’ water which periodically fouls and even destroys all electrical appliances which use water, necessitating new equipment. Now that I had the PTH softener installed, there are no more scale deposits in my kettle and the water is as pure and drinkable as bottled water for sale…the water now tastes pure and I most grateful for the PTH device.” Mrs GH Vermeulen, Stilbaai
“Reins Nature Reserve bought a PTH32 Israeli PTH water conditioner to treat the extraordinarily hard and brack water. The PTH was installed on the main water supply line. The results were astonishing….1. Lime scale layers on the irrigation system were broken up within days and the nozzles are once again clean and good as new. 2. Sensitive crops are grown and no negative effects observed. 3. The environmentally friendly (no chemicals needed) PTH even improved the TASTE of the water.” Nico Malan, Manager Rein Farming, Albertina
4. Does it prevent and remove existing scaling and rust?
The only system that is proven to remove built-up rust and scale is the PTH.
“I own the Vleismark Butchery in Darling, which is serviced with hard borehole water. Not only is the water very brack, but it also contains a tremendous amount of iron, which causes red deposits and stains. The PTH20A I installed completely removed the red deposit; soaps and detergents now foam much better, with consequent savings; scale deposits in the toilet were cleared and removed; and my visitors frequently remark the taste of my new PTH improved dramatically. I recommend the PTH as a device which is worth the money I paid for it, over and again.” Parker Kriel, Former Deputy Mayor, Darling
5. What are the maintenance and long-term operating costs?
All other systems except the PTH require maintenance and replacement parts, membrane or filters. Once the PTH is installed, it operates without maintenance or any replacement parts.
“There is an excellent product on the market. It makes all pipes, geysers and drip irrigation completely scale and rust free. They come in different sizes according to your needs. It works without electricity and is maintenance free. You just hook it up to your waterpipe coming from the water tank. It needs half a meter uninterrupted space either side of it to create a venturie. It’s manufactured in Israel. There’s only one agent in SA. It’s not big and he sends it through the mail. We bought one and we’re very happy with it.. email@example.com Cell: 0829009253.
“Since the installation of the (PTH) water softener here at the Club, we have noticed a vast improvement in the quality of the water.”Jonathan Rumbelow, Bloemfontein Health & Racquet Club
