Potable water treatment
Where does the potable water (drinking water) come from?
What is the problem?
Surface water contains natural organic matters (NOM) that originated from the decomposition of leaves, plants and animals. NOM is a common name and, thus, has a large variety in size and structure. Current technologies applied in the drinking water treatment can remove up to 90% of the NOMs, however, difficult to remove small sized NOMs in an efficient way.
NOM gives color to the water. Photos bellow show tap water taken at the laboratory in Oslo (right) and water treated by reverse osmotic (RO) membrane (left). As you can see, the tap water is colored, yellowish, due to the remaining NOMs.
Major challenges of today
Pesticides in the water source are another concern as they can have high health risks.
