It is the removal of contaminants such as microorganisms (bacteria and viruses), heavy metals, dissolved chemicals and anything else that may make it more suitable and safer for human consumption as well as for use in industries.
Members of the public so they can have safe drinking water is just one example. Industries such as power generation benefit too. Machinery such as boilers can last longer, and also products can maintain their high quality in the food and beverage industry with water that meets the necessary standard.
These are tiny polymer microbeads that swap out unwanted ions into ones that are more favoured. The process of ion exchange is reversible so the resin can be reused. These beads are insoluble in water.
It has many uses in the water treatment industry. For example, it is used to soften water by removing the hardness ions calcium and magnesium, so scale is prevented. It’s used for demineralization (DI water) with laboratories and pharmaceutical production benefiting from this. Commercially, it has great success in home water softeners.
Deionisation resin, or DI Resin as its often shortened to is a type of ion exchange rein used to take away dissolved ions from the water via through the process of ion exchange. It is made up from a mix of cation and anion exchange beads.
It can have many purpose but its main benefits are seen in the window and car cleaning industry. The dissolved solids being eliminated means the water dries without leaving the mineral marks so you get spot free cleaning. In the lab industry, it is used to produced deionized water which is absolutely necessary for maintaining accurate results in biological or chemical analyses for example.
These are replaceable internal components inside a water filtration system that is responsible for the filtering. As water flows through, it takes away the unwanted substance. They’re often found in shower filters or RO (reverse osmosis) systems.
If you want to improve the taste and eliminate unwanted odours in your tap water, then you may use one of these. They can remove chlorine and also help in reducing limescale so if you have hard water, you should consider this if you want your household appliance such as kettles and coffee machines to last longer.
This is a type of ion exchange resin that is designed to take away hardness minerals (calcium and magnesium) from water. It replaces the unwanted ions and replaces it with sodium ions to form soft water.
It has many applications with it most noticeably being used in households in water softening units. These are usually installed at the POE (point of entry) when water enters the home.
Also referred to activated charcoal, this is a highly porous type of carbon that may be made from coconut shells, coal, or peat. Essentially, materials that are carbon rich. Coconut shell is commonly used as it performs brilliantly for water purification.
Activated treats water by a process called adsorption. This involves contaminants adhering to the porous surface area of carbon granules such as coconut shells. As the water passes through the pores, chemicals and odours and organic pollutants all stick to the surface of the carbon, leaving cleaner water at the end. Typically, it’s used to remove chlorine and compounds that would negatively impact the taste and odour of water.
Kdf-55 is a mixture of copper and zinc bonded together into a high purity alloy that is used within water filtration. Its job is to remove chlorine and reduce heavy metals such as lead and mercury as well as helping with the reduction of scale in water pipes.
You would typically see KDF-55 used in shower filters as performs brilliantly in hot water. It is used here to remove chlorine and heavy metals so the water is kinder to hair and skin, therefore reducing skin dryness. It can also be used as a pre-filter in under sink system to before the water passes through a primary filter, like activated carbon for example.
This is the process of removing minerals which cause water to be hard. (calcium and magnesium minerals). It’s done through a process called ion exchange where the sodium or potassium ions replace the hard water causing ones in the water.
There is a wide variety of benefits to water softening which include: skin feeling softer due to less hard water exposure, minerals spots on dishes being removed so glassware is shinier and free of spots. Not forgetting, limescale is built up less in appliances and pipes so equipment lasts longer.
