OZONE

Ozone is a gas that is generated by ultraviolet rays or corona discharge by splitting the oxygen molecule in to two individual atoms which then attach themselves to another oxygen molecule, thus forming an O³ molecule.

This O³ molecule is very unstable with a short half life and it will revert back to oxygen in a short period of time. During this short life cycle and process, the O³ molecule can therefore be utilised for sanitation and sterilisation purposes.

Ozone is second only to fluorine as an oxidant and has been used in Municipal water treatment plants and in the medical field since the late 20th Century. Because of its short half life and its tremendous oxidising capabilities, it can be used in situations where residual chemicals are undesirable. For example in food preparation or water purification, where chlorine is used to kill bacteria, any chemical residues are undesirable and harmful. Residual chemicals will result in tainting of the foodstuffs and effluent and waste removal are problematical.

Ozone will work 3 000 times quicker and is 2.5 times stronger than chlorine.

In water purification and effluent treatment it is used to disinfect the water, remove algae, improve flocculation, oxidise iron and manganese and remove colour and odour.

In air treatment it is used to eliminate odours, sterilise the air and ducting and remove and neutralise pollutants such as cigarette smoke, carbon monoxide and noxious gases. It will also prevent cross contamination of airborne diseases such as flu or tuberculosis.

In the Medical field it is used to purify and oxygenate blood to compliment normal proceedures, to improve the immune system and for treating wounds, ulcers and skin ailments.

IS OZONE DANGEROUS?

At high levels in the air ozone can be harmful for humans.  Therefore the correct sizing of ozone generators is important to achieve effective bacteria kill as well as be comfortable for humans. For this reason we recommend applying ozone only to semi occupied or non occupied areas unless a sophisticated sensors system is installed to maintain the correct levels.

ULTRA VIOLET IRRADIATION

UV-C light is germicidal - i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.

Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance. Ultraviolet purifiers utilize germicidal lamps that are designed and calculated to produce a certain dosage of ultraviolet (usually at least 16,000 microwatt seconds per square centimeter but many units actually have a much higher dosage.) The principle of design is based on a product of time and intensity - you must have a certain amount of both for a successful design.

IONS/ANIONS INFORMATION 

Ion are produced when electrons is collide with molecules in the air (mainly oxygen molecule). Ions with a negative charge are called anions. They have no color or taste. In nature, anions exist everywhere. Thunderstorm and lighting, photosynthesis of plants and waterfalls are all sources of anions and explain the fresh air feeling after a thunderstorm, in a forest or by a waterfall.

An imbalance of positive or negative ions ( or a prevalence of positive ions caused by combustion or electric motors and heat and friction) explains such phenomena as Sick Building syndrome, road rage, Witches winds and the peculiar reactions in some animals and humans at Full Moon periods. In offices, reception areas or homes occupants “soften” the atmosphere by installing Water features or indoor plants and generate anions.

Ionisers will do the same thing and have the additional advantage of flocculating dust or smoke particles or microrganisms and pollen out of the air to maintain a clean indoor atmosphere.

PHOTOCATALYTIC NANOTECHNOLOGY ( TITANIUM DIOXIDE)

A new innovation called photocatalytic nanotechnology is now been utilised to clean and purify indoor air. The technology consists of Titanium dioxide (TiO2) crystals, only 40 nanometers in size, which form a molecular machine powered by light. TiO2 is a semiconductor charged by ultraviolet photons. When these nanoparticles are charged, powerful oxidizing agents called hydroxyl radicals are produced. These free radicals destroy airborne germs and pollutants in the air.
