FAQ on Water Softeners, Water Filters and Water Coolers
What is hard water?
Water which contains dissolved chalk, lime and other minerals is known as Hard Water.
What is soft water?
Soft water is water which does not contain dissolved chalk, lime and other minerals.
How can I get soft water?
Soft water can be obtained by using a water softener system. Water softeners remove chalk, lime and other minerals from hard water to make it softened and this process is called water softening.
How long does a water softener last?
A good water softener can provide soft water for over a decade when fed with the right amount of salt and water softener resin.
How much does a water softener cost during operation?
The monthly recurring cost of maintaining an operational water softener is less than €1.95 per person per household.
What are the different types of water softeners available?
Water softeners can be classified into 5 types:
- Single Tank Water Softeners
- Twin Tank Water Softeners
- Non-Electric Water Softeners
- Metered Water Softeners
- Timered Water Softeners
Which types of salt are used in a water softener?
The types of salt used in water softeners are as follows:
- Black salt or rock salt or ground salt
- White salt or sea salt or crystal salt
- Dissolving salts or underground salts
How often should salt be added to a water softener?
The salt level of water softeners should be checked every month and must be kept above 50% at all times.
What is limescale?
Limescale is the formation of sedimentary deposits on the sides of boiler vessels and water outlets. Limescale gets formed due to excessive mineral deposits in hard water.
What are the benefits of using a water softener?
Water Softeners provide real cost savings in service, maintenance and replacement of water heaters, dishwashers, washing machines and showers and also extends their lifespan. Read about the benefits of using water softeners.
What are the different types of water coolers available?

How can limescale be removed?
Removing limescale is a chore! Have your water softened instead and avoid limescale.EWT Water Softener Systems bring you soft water and zero limescale.
What is a water softener?
Water softeners are household devices which remove chalk, lime and other minerals from hard water. Water softeners soften hard water through a process called water softening and are usually installed into the tap water supply.
How to differentiate between hard and soft water?
When a water sample is mixed with washing powder or soap, hard water produces less lather while soft water produces more later, in a shorter period of time.

What are the different types of water filtration systems available?
The different types of water filtration systems available are:
- Reverse Osmosis Water Filter Systems
- Membrane Based Water Filter Systems
How can I get clean, drinking water?
Clean, drinking water can be obtained by installing a water filtration system. Raw, unclean tap water goes into a water filter to become clean, filtered drinking water.
What are the benefits of using a water filter?
Besides getting clean, filtered drinking water, water filters are able to remove far more water contaminants than any other water purification method. The benefits of using a water filter are as follows:
- Removes Water Contaminants
- Costs Much Less than Bottled Water
What is a water cooler?
A water cooler is a device which stores water and provides chilled water on demand. Water coolers are usually installed into commercial water mains.
How is distillation performed?
Distillation is performed by a heat source which vaporises water. The water vapour from distillation is condensed to get purified water.
Is boiling water good for health?
- Never drink boiling water!
- Wait for boiled water to cool down before consumption.
- And yes, boiled water evaporates all impurities from water, making it safer and healthier for drinking.
- Don’t forget to filter your boiled water.
Can I get any special offers on water filters?
Yes, you can! EW Technologies – Ireland’s leading water filter company launches special offers on the best-designed water filters in Ireland.
Where is EWTechnologies located?
EW Technologies – Ireland’s leading water filtration and water softener company has offices on Galway and Dublin. We also have offices in London, Poland, Lithuania and France. We are an Irish owned company.
What is a water filter?
A water filter is a household device which filters water contaminants from drinking water. Water filters are capable of converting raw, tap water into clean, drinking water.
What are the benefits of the reverse osmosis process of water purification?
Water purification systems which use the reverse osmosis purification process are cheaper and energy-efficient when compared to purification units which use the water distillation process.
How is water filtration performed?
Water filtration is performed by means of a water filtration media, over which raw water flows and becomes purified water.
The water filtration media blocks the passage of water contaminants through physical obstruction, chemical adsorption, or a combination of both processes and gives clean, filtered water as the end result.
Do I need soft water in my swimming pool?
Not really! Soft water is good for laundry and bathing because it produces lather much faster than hard water. It’s not necessary to have water softened in a swimming pool.
What is meant by flow rate?
Flow rate is referred to the volume of water which passes through a water cooler, water softener or water filter per unit of time. The higher the flow rate, the more powerful the water treatment equipment.
Can I use soft water for cooking?
Once softened water is passed through a water filter it becomes filtered. The filtered water may be used for cooking purposes.
What is raw water?
Any form of untreated water is known as raw water. Tap water and surface water are examples of raw water.
What is the molecular composition of water?
Each molecule of water contains 2 atoms of Hydrogen and 1 atom of Oxygen. The molecular formula of water is H2O.
What is meant by primary treatment of water?
The process of water filtration by using physical filters or through chemical means is known as pre-treatment or primary treatment of water.
What is meant by secondary treatment of water?
The removal of organic matter from waste water by making use of biological processes is known as secondary treatment of water. Sewage treatment plants implement secondary treatment of water for water purification.
What is meant by tertiary treatment of water?
The advanced cleaning of waste water which helps remove nutrients such as phosphorus, nitrogen and most suspended solids from water is known as tertiary treatment of water.
What is meant by desalination or desalination of water?
Desalination or desalination of water refers to the process of removal of some amount of salt and other minerals from saline water.
What is meant by potable water?
Potable water is water which is fit for consumption by humans and animals. Potable water is also called drinking water.
What is meant by depth filtration?
Depth filtration is the process by which suspended solids in water are removed and collected by means of a filtration media.
What is meant by differential pressure?
Differential pressure is defined as the difference in pressure between inlet side and outlet side of the water filter.
What is meant by effective filtration area?
Effective filtration area refers to the total area of the filtration media which is exposed to water flow.
What is meant by screen filtration?
Screen filtration is a mechanical water filtration technique which uses a filtration screen to remove impurities from water.
What is meant by vapour pressure?
Vapour pressure is the pressure at which water evaporates at a given temperature.
What is referred to as – upstream in a water filter?
Upstream is the point where water flows into a water filter. The inlet side of the water filter is referred to as – Upstream.
What is referred to as – downstream in a water filter?
Downstream is the point where water flows out of a water filter. The outlet side of the water filter is referred to as – Downstream.
What is the boiling point of a substance?
The boiling point of a substance is the temperature at which the vapour pressure of the substance is equal to the atmospheric pressure.
What is meant by pre-filtration of water?
Pre-filtration is a water filtration method which involves the removal of coarse particles or large debris in water prior to secondary filtration processes for water purification.
What is meant by media filtration?
Media filtration is a water filtration method in which graded particles such as sand, gravel or other granular materials perform the filtration of water.
