Water is a basic and indispensable need in life. We need it to keep our body hydrated and for good health. However not all water sources are safe for drinking or cooking. This is the reason why water purification and water treatment systems play an essential role in every community.
Homes can either install their own water purification and softener systems or they can make use of commercial water treatment centers that can supply high quality water. The main advantage of the latter is that you don’t have to invest on filtration and treatment equipment but you have to depend and trust on the business that supplies it. On the other hand, investing on water filtration systems for your home can be expensive and involves maintenance and regular water quality tests, but can give better returns in the long run especially for buildings, commercial establishments and homes that need huge volumes of high quality water every day. It’s an investment that can prove to be an efficient and self-sustaining, both for residential and commercial water systems. Depending on your needs, filtration systems can effectively remove sediments, iron, rust, chlorine, volatile organic compounds (VOCs), bacteria and other pollutants. The following are common water filtration systems:
* Carbon block filters – These are effective in removing chlorine and other VOCs.
* Ceramic filter – This is mainly used to filter out sediments or large particles, but not for drinking water.
* Distillation systems – This involves boiling water and collecting condensed vapour. Equipment can be expensive but it’s effective in killing bacteria that cannot live beyond water’s boiling point.
* Reverse Osmosis – This is a very slow process but an economical choice. It can remove organic and inorganic contaminants like colloids, pyrogens, dissolved solids and heavy metals.
* Water softeners – Calcium, magnesium, barium, and rust can build up on water supply as it passes through pipes, and these can affect surfaces like your clothes, sink, glasses etc. Soft water is best for household use and the process utilizes ion exchange to decrease chemical concentration.
* UV sterilizers – This can remove bacteria, viruses and microorganisms that typically cause diarrhea and other gastrointestinal problems. However it cannot filter out hard water sediments and dissolved contaminants.
* Ionizer – Also called as alkaline ionizer, it’s a device attached to home water systems that changes water pH levels from acidic to basic. Alkaline water has pH levels between 7 to 10 and this is within similar pH levels of that of fresh spring water. This is usually recommended for health benefits, as higher pH levels can help control your body acidic levels, acts as anti-oxidant and can improve cellular processes.
There are also other types like reverse osmosis, ozone, UV and activated carbon filter systems. Each one has their own advantages and disadvantages in terms of the type of contaminants filtered.
