Quality Solutions
Water Treatment Quality Management:
The type of treatment
applied to water will depend on the perceived quality defect and on the
use to which the water is to be put.
Typical defects
encountered:
 Excess hardness- Excess iron and manganese
- Foul odours
- Colour
- Tastes
- Presence of micro-organisms
- Presence of heavy metals
- Presence of particulate matter
- Corrosive water
- Highly polluted water such as sewage and industrial
wastewater
- Presence of treatment chemicals such as aluminium,
fluoride, and chlorine
All of the
above defects can be remedied using well-proven technologies. Many
defects have upper limits set by law and must not be deviated from.
Note: In Ireland
your local County Council authority may grant up to 85% of the cost of
domestic water treatment. Enquire
here for further details.
Principal Sources of Raw Water:
- The ground - accessed through boreholes using submersible
pumps
- Surface water such as lakes
- The sea
- Rainwater
The treatment applied
depends on the defect or the anticipated defect. Table
1 gives suggested solutions to common water quality problems.
These solutions may be applied alone or in combination. For instance,
one could use particle filtration, carbon filtration, ion exchange
resins (softener) and UV in combination. The result will be water which
is soft, sterile and free from particulate matter, odours and tastes.
