Water
contamination whether the source be river, lake or bore can
be catagorised into four groups, some are safe and some potentially
very harmful. They can be removed to varying degrees with an
array of technologies. Our zeolite products can be used to treat
the suspended clays & vegetable matter along with some of
the tannins.
Suspended clays & vegetable matter
The first and third groups are generally
quite harmless, they may affect the appearance, flavour and
smell of the water but do us no harm. A fixed deep bed of a
suitable filter media such as zeosand zeolite provides a simple,
inexpensive and effective means of continuous and ongoing removal
of these contaiminents. Employment of the 1-2mm product is recommended
for most applications.
Viruses,
Bacteria, Protazoa & Nematodes
Viruses and the like need to be
killed either by boiling, uv or chemical treatment.
Dissolved tannins & salts
Tannins are simply leached colourings
and trees, add milk and sugar and you have a kind of tea.
These can be easily removed by ultra fine filtration similar
to that used to remove suspended solids.
Organic & Inorganic industrial chemicals
These are much more serious and
although "activated" carbon if used correctly can
remove many of these volatile organic compounds (VOC) if the
water contains these you would be wiser keeping well clear
and find a new water supply
