water treatment

Water treatment systems are used to make water acceptable for a desired end use for entry to, use within, or exit from a premises. Galway Water Solutions specialise in water treatment systems for water quality correction entering premises and at drinking points.

Primary or point of entry water treatment systems are generally designed for improving water quality entering a premises to a high standard for high volume general domestic use for purposes such as bathing, showers, washing clothes and dishes and flushing toilets.

Secondary or point of use drinking water filter systems such as reverse osmosis filter units can be used in combination with primary water treatment systems to polish water up to an extremely high quality for potable (drinking) water quality within premises.

Water purification is the removal of contaminants from untreated water to produce drinking water that is pure enough for its intended use.  Substances that are removed include suspended solids, bacteria, viruses, water hardness minerals and minerals such as iron, manganese and sulphur along with man made chemical pollutants including fertilisers.

Because of the wide complexity of contaminant combinations and varying concentrations of contaminants in different water sources with a wide range of flow demands, no single solution or universal standardised selection of processes can be used as a one stop panacea, nor is there a unique solution or selection of processes for any given type of water.

Many combinations of processes can be used to correct water quality issues that fall under the scope of water treatment, some using filtration and separation methods, some aiding filtration and others types that do not employ filtration methods:

Backwash media bed filtration using precipitation, absorbtion or adsorption, coagulation, flocculation, mechanical barrier filtration, cross flow membrane filtration or hyper-filtration, nano-filtration, ultra-filtration, sub-micron filtration, microfiltration, ultraviolet disinfection, aeration, chlorination, ozonation, distillation, pH dosing, ion exchange, mixed bed de-ionisation, de-alkalising, acidic dosing and lesser used methods such as pre-coat filtration, centrifugal separation, settling and sedimentation.
