Water which contains dissolved chalk, lime and other minerals is known as Hard Water.
Soft water is water which does not contain dissolved chalk, lime and other minerals.
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.
A good water softener can provide soft water for over a decade when fed with the right amount of salt and water softener resin.
The monthly recurring cost of maintaining an operational water softener is less than £1.60 per person per household.
Water softeners can be classified into 5 types:
The types of salt used in water softeners are as follows:
The salt level of water softeners should be checked every month and must be kept above 50% at all times.
Limescale is the formation of sedimentary deposits on the sides of boiler vessels and water outlets. Limescale forms due to excessive mineral deposits in hard water.
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.
The are two main types of water coolers available.
There are many benefits of using a water cooler. Two main benefits of using water coolers are:
Buying and using an EWT Water Softener can save UK households roughly £80 per month! View our Water Softener Cost Savings Calculator for more information.
Removing limescale is a chore! Have your water softened instead and avoid limescale. EWT Water Softener Systems bring you soft water and zero limescale.
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.

The different types of water filtration systems available are:
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:
A water cooler is a device which stores water and provides chilled water on demand. Water coolers are usually installed into commercial water mains.
Distillation is performed by a heat source which vaporises water. The water vapour from distillation is condensed to get purified water.

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.
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.
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.
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.
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.
Once softened water is passed through a water filter it becomes filtered. The filtered water may be used for cooking purposes.
Any form of untreated water is known as raw water. Tap water and surface water are examples of raw water.
Each molecule of water contains 2 atoms of Hydrogen and 1 atom of Oxygen. The molecular formula of water is H2O.
The process of water filtration by using physical filters or through chemical means is known as pre-treatment or primary 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.
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.
Desalination or desalination of water refers to the process of removal of some amount of salt and other minerals from saline water.
Potable water is water which is fit for consumption by humans and animals. Potable water is also called drinking water.
Depth filtration is the process by which suspended solids in water are removed and collected by means of a filtration media.
Differential pressure is defined as the difference in pressure between inlet side and outlet side of the water filter.
Effective filtration area refers to the total area of the filtration media which is exposed to water flow.
Screen filtration is a mechanical water filtration technique which uses a filtration screen to remove impurities out of water.
Vapour pressure is the pressure at which water evaporates at a given temperature.
Upstream is the point where water flows into a water filter. The inlet side of the water filter is referred to as - Upstream.
Downstream is the point where water flows out of a water filter. The outlet side of the water filter is referred to as - Downstream.
The boiling point of a substance is the temperature at which the vapour pressure of the substance is equal to the atmospheric pressure.
Pre-filtration is the water filtration method which involves the removal of coarse particles or large debris in water prior to secondary filtration processes for water purification.
Media filtration is the water filtration method in which graded particles such as sand, gravel or other granular materials perform the filtration of water.
