Specialist Systems

For well water and other types of naturally sourced raw water it is essential that accurate INAB accredited water analysis is conducted prior to equipment selection.

Iron removal filters are popular in well water treatment and there are several types depending on the overall water chemistry, pH conditons and lime levels etc.

Hard water is almost certainly found in most borehole water wells.  Galway County and Connaught in general has the largest swathe of karst limestone bedrock in Ireland. A water softener or bacteriostatic well water softener is usually chosen to deal with high lime levels found in wells.

Odour filtration systems deal with hydrogen sulphide (rotten egg odour), ammonia, musty organic odours of bog water to the faecal or raw sewage smell of bacterially polluted waters. Other artificial chemical smells come from some treated waters, notably with the use of high levels of chlorine.

Heavy grit, sand or turbidity (finely suspended silt or colloidal silicas) also have their specialist applications and need to be even more precisely evaluated.

Bacteria is also found in most well water and occurs intermittentlythroughout the year depending on rainfall. An ultra violet steriliseris used after some form of softening or primary treatment of iron orother nuisance contamination to keep the ultra violet inner quartzsleeve free from obstruction.

Reverse osmosis deals with the final concentrations of toxic heavy metals, nitrates, nitrites, sodium and other dissolved parameters harmful for drinking water use.  A reverse osmosis filter should only be used after well water has been properly treated for primary filtration of all the high levels of nuisance parameters like iron, manganese, hardness, grit, silt, turbidity, bacteria etc.

Colour is found in well water seasonally throughout the year especially after heavy rainfall, so carbon systems are recommended to keep water clear of tannins and allow ultraviolet systems to perform their job correctly.  Tannins are the product of organic run off from plants, trees and vegetation that find their way into surface waters and then into ground water.  Colour in water or true colour found on laboratory water reports is a measurement of the clear to translucent look that tannins give water; a yellowy brown tint, not to be confused with iron which gives a reddish brown cloudy look to water caused by oxidation of the iron when exposed to air, leaving a cloudy or "turbid" precipitate which settles as a sediment to the bottom of a sample container after a prolonged period, which tannin colour is unable to do.

Anecdotal evidence of water history and water use is an extra tool in helping along with the evaluation of assessing the need for a particular water treatment system.
