TANKMANS Ozone system flush will treat, condition and filter the entire contents of your water tank, without using chemicals or draining your tank.


The Ozone filtration process will take 48 hours, but unlike chemical sterilisers, you can continue to safely use your house water as normal through the process.

What's the quality of the water stored in your tank?


ree

Is your tap water brown or murky? Does your drinking water taste foul or musty? Rotting leaves could cause this in your water tank. If your tap water tastes bad or smells foul, there are pollutants, bacteria or other contaminants in the water tank and, thus potentially in your drinking water.


Roof water often contains faecal and urine deposits from birds, possums, rodents and tannins from decaying organic matter. Ozone kills coliform bacteria such as E.coli on contact more effectively than chemicals. Additionally, it treats fungus, mould and yeast spores.


Spray drift in agricultural areas also poses a severe risk to roof or groundwater – potentially contaminating these with pesticides and glyphosate. For this purpose, ozone is very effective in neutralising these contaminants – a particular benefit to people with compromised immunity. TANKMANS Ozone system flush will treat, condition and filter the entire contents of your water tank, without using chemicals or draining your tank.

How does ozone purify water?

Ozone is oxygen (O) with three atoms (O3) instead of two atoms (O2). Therefore, it consists of three oxygen atoms, “O3”, with a high oxidation potential. In chemistry, this property means that the gas is particularly “reactive”. This is because its third atom “steals” an oxygen atom from everything that comes into contact with ozone. Thus, ozone is one of the strongest oxidants of all and is used in water treatment worldwide.


Since it is not water-soluble, ozone reacts with the pollutants in the water. This process is called ozonation. The oxidation process destroys unwanted contaminants such as viruses, bacteria or other pathogens by causing the disintegration of their cell membrane.

Ozone binds toxic components

Although its oxidative properties are powerful, the lifetime of ozone is very short. As soon as it comes into contact with viruses, bacteria, odours, these are destroyed by the extra oxygen atom in the ozone! During ozone water treatment, the cellular components of the bacterial cell walls of all harmful substances in the environment are oxidised. As soon as the ozone has reached the individual cells, it oxidises all components – what remains is pure oxygen.


In addition, ozone disinfection has clear advantages over the conventional and frequently used chlorine disinfection of water. In addition, this type of water disinfection also decomposes other substances that react with oxygen. These include all human substances, organic substances, pesticides, cyanides, phenols, or even gases such as hydrogen sulphide.


TANKMANS Ozone System is a two-component water treatment system. The first module is the water ozone generator with an integrated air pump outside of your water tank. The second module is a diffuser with a washable filter element placed in your water tank. The ozone generator’s output is fed by tubing to the diffuser, generating millions of ozone-saturated bubbles inside the filter element and released in your drinking water.


How does it work?

As these bubbles rise inside and exit the filter module, the ‘friction’ resulting from them moving through the water draws more than 50,000 litres of water through the filter in 24 hours – removing oxidised particulates, capturing existing debris and preventing it from accumulating on the bottom of the tank. This method of filtering the water before ozonation is key to increasing the ability of the ozone to be absorbed by the water.


ree

As the ozone bubbles ascend through the water in the tank, they continue the ozone saturation process. The AquaZone Ozone system then filters oxidised material. What remains is healthy, clean drinking water, ideal for all your domestic water uses. Thereby, the electricity costs are only about $7.50 per month. Ozonation protects you and your family against virtually all toxic and harmful unwanted bacteria, germs, viruses, fungi and protozoa.

When were your gutters last cleaned?
When were your gutters last cleaned?

Cleaning gutters is something that may seem straightforward to many people, and it is important to clean gutters regularly. The traditional way was to take out a ladder and a scoop, climb up the ladder, and scoop out any sludge, sediment, and debris and throw them out. Then, move the ladder down a little more and repeat. However, nowadays there is a much better way to clean gutters; using a vacuum. Vacuum gutter cleaning offers many advantages and is faster, safer, and more effective.

How Does Vacuum Gutter Cleaning Work?

A vacuum gutter cleaner is a special vacuum that can reach up 3 storeys while the operator stays on the ground. But just because the operator remains on the ground doesn’t mean they’re cleaning blind. The end of the vacuum has a camera with a real-time feed that transmits to the ground. This means that if there’s something strange like toys or birds up there, they won’t get vacuumed up along with the dirt and debris into the tank.

We use SkyVac, which claims to be the world’s most powerful gutter cleaning system.


Why SkyVac Gutter Cleaning?

There are many advantages to using the SkyVac gutter system. The benefits to you are that using vacuum gutter cleaning is safer, faster, and gives a better, more comprehensive clean. SkyVac can lift out sediment, clear out sludge, pickup lost toys, and remove growing plants with ease. Even large clumps are no problem, as they can be lifted away easily.
