Water filters are the most efficient way of reducing water contamination and removing contamination in your water. Contaminated water contains sediments and disease-causing microorganisms such as bacteria, protozoa, and viruses. There are filters specialised for filtering certain water contaminants, and there are generalised ones that filter many contaminants. Modern filters come in various shapes and sizes and are capable of filtering chlorine, fluoride, heavy metals and other sediments. The following are some of the types of water filters and how they operate.

Reverse Osmosis (Osmotic Membrane Technology)

This is the most efficient filtration technology, and it’s capable of filtering nearly all the water contaminants including heavy metals, fluorine, chlorine, sediments, and excessive nutrients and minerals. The technology applied here is the use of semi- permeable membrane combined with a pressure of about 35- 40 psi. The membrane has tiny pores, which can only the tiny water molecules to pass through.  All other particles are left behind, washed and piped out to the main drain.

The semi-permeable membrane is usually fitted with other filters in a system known as Reverse Osmosis Water Filtration System. 5 stage reverse Osmosis System uses a total of 5 filters to ensure that the water is completely purified. The filters which are usually combined with this membrane include sediment pre-filter, carbon pre- filter and a carbon post- filter.  The pre-filters protect the osmotic membrane from damage while the post-filter is meant to polish the filtered water to ensure it is of high quality. This water can then be stored in filtered water coolers, office water coolers and let out in water cooler dispensers, faucets or drinking water fountains.

Activated Carbon Filters

Just as the name suggests, these water filters are made up of special carbon. The type of carbon used here is the one that has been activated to attract a large number of impurities present in water. Activated carbon filter can be found as a complete stand-alone filtration or in complex systems like the reverse osmosis system. Its design technique allows it to have large bonding sites for organic impurities.

These filters work by a process known as adsorption. This is the process through which the impurities found in water chemically bond with the activated carbon. After water enters the filter, these impurities typically attach themselves to the activated carbon. The level of filtration depends on some factors such as the speed of water flowing through the filter and the concentration of carbon.

Alkaline/Water Ionizers

The alkaline water ionizers water filtration technology works through a process called electrolysis, which raises the water PH. Usually, water is subjected over electrically charged plates that separate it into its acidic ad alkaline components. The negatively charged electrodes attract the positive ions hence leading to reduction. The positively charged electrodes attract the negatively charged ions hence resulting to water oxidisation. The reduced water is ideal for cooking and drinking while the oxidised water can be used for laundry, cleaning utensils, cleaning wounds and even for sterilisation.

UV Filters

UV filters make use of ultraviolet radiation to get rid of pathogens that may be present in your water. In this process, water is usually exposed to UV rays which are then absorbed by the microorganisms found in water. The UV rays alter the DNA of these microorganisms hence destroying them and leading to their death. This is the best way of eliminating waterborne diseases to provide safer drinking and cooking water.

Infrared Filters

Infrared water filters are commonly used for water softening. They depend on light and heat to give water a softer feel. Soft water is usually free from heavy metals and excess minerals and nutrients.

Conclusion

The type of water filter you choose depends on the level of water contamination. When purchasing a water filter, you should consult an aquafil expert since different water filters come with different filtration technologies. Aquafil will advise you on the best system that will solve the water problems in your area. Get in touch for information on water filters, refill statins and other  products including bubblers, water coolers Sydney, office water coolers, and water cooler dispensers and drinking bubblers among other quality products provided by aquafil. These are better solutions than buying single use bottled water every day, which will prove expensive and environmentally unfriendly in the long term.
