Tap Water Treatment

Water Treatment

In order to make tap water 'safe' to drink, water companies employ a wide range of techniques in order to ensure what is considered a low risk of long term harmful effects to humans.What is in Tap Water

Most tap water is re-used from raw sewage with the first stage of the process being solids separation whereby the solid elements in the raw sewage are separated from the water using techniques such as settling and filtration.

Substances that aim to be removed during the treatment process include: bacteria, viruses, fungi, algae and harmful minerals such as manganese, sulphur and iron. Water companies also have to consider chemical pollutants such as fertilisers which have entered the water supply from industrial farming.

Treatment Processes for Tap Water

Municipal authorities around the world generally employ a combination of processes to treat drinking water. These include:

Pre-chlorination - the addition of chlorine to the water designed to halt biological growth but not disinfect the water.

Aeration - in combination with pre-chlorination, aeration attempts to remove the presence of dissolved iron and manganese.

Coagulation - this is where dissolved solids are coagulated to form a scum on the surface of the water. In order to encourage coagulation, reagents known as polyelectrolytes are added to the water.

Sedimentation - is the process used whereby suspended solids, which are now larger in size due to coagulation, are separated from the water.

Filtration - a variety of filters are used to remove particles.

Desalination - is the removal of salt from the water.

Disinfection - this is usually the final stage in the water treatment process in order to limit the effects of organic material, suspended solids and other contaminants. The primary methods used for the disinfection of water are ozone, ultraviolet irradiation (UV) and chlorine. There are numerous alternative disinfection processes that have been less widely used including chlorine dioxide, potassium permanganate, chloramines and peroxone (ozone/hydrogen peroxide).

The NSF Certified Biostone Filter

All Jupiter Science Emco Tech water ionizers use world class NSF certified Biostone filters to filter the water before it enters the ionization chamber. This means you can rest assured that the water from your Jupiter Science ionizer is as clean and healthy as can be. Below are just some of the contaminants which will be removed by your Biostone filter:

Contaminant Standard mg/litre Result mg/litre
Potassium Permanganate  10.0  2.70
Lead  0.05  ND
Flouride  1.50  ND
Arsenic  0.05  ND
Cyanide  0.01  ND
Mercury  0.001  ND
Selenium  0.01  ND

What Is the Best pH?

Municipal water companies generally do a good job of ensuring that our tap water is of a quality that the majority of people can drink without the need for concern.

There is, however, increasing concern over new types of contaminants being found in our water. These are generally pesticides and pharmaceutical products which haven't been regulated yet because where they are found they are found at what are considered low levels and at levels where they are presumed not to be harmful to public health.

The use of a good water filter is the single best step you can take to insure yourself against exposure to most water contaminants. Always check to ensure that the filter your choose has been independently certified to do the job it claims - such as the NSF Certified Biostone filters.

So, is industrially treated tap water bad for you? Well, we don't consider it 'good' water. The fact that tap water is not considered a significant risk to most people is a good thing. But what we do know is that Western populations are suffering from significant increase in all kinds of chronic conditions such as dementia and we are sure that improving the quality of water we consume can only have a positive effect.

It is simple and easy to have water that is clean, oxygenated, alkaline and filtered by using a Jupiter Science Emco Tech ionizer for the water you drink.
