It was reported in January 2022 that the groundwater in a city and eight towns in Batangas province have been found positive for arsenic contamination. The areas with high levels of arsenic contamination were revealed to be the municipalities of Laurel, Balete, San Nicolas, Mataas na Kahoy, Alitagtag, Santa Teresita, Lemery, Taal and the city of Tanauan.
Every year, millions of children die of water-borne diseases. In fact, diarrhea is the second leading cause of mortality for children below five years old. It is because 780 million people globally still drink contaminated water due to lack access to improved water sources. For this reason, many people prefer to install water purifier at their home nowadays. It is like having your own water refilling station to ensure that you only drink pure and safe water no matter how contaminated your water source is.
Do you have an idea how clean is your drinking water? Most people know the importance of drinking water but not everyone knows the difference between the water from their faucets and the bottled waters they buy in stores. The quality of water can differ depending on how it is treated. If you want the purest drinkable water, choosing water filtered through reverse osmosis is one of the best choices.
Reverse Osmosis, commonly known as RO, is a technology that is used to purify the water by pushing the water under pressure through a semi-permeable membrane. It is a membrane that will allow some atoms or molecules to pass but not the contaminants in the water such as suspended solids, salts, organics and microorganisms. It also contains a sediment filter and a carbon filter in addition to the RO membrane. After water exits the membrane, it passes through a postfilter to polish the drinking water before it enters a dedicated faucet.
Mechanical filtration is the most common way of removing physical contaminants in water. In this article, we look at four types of mechanical filtration and their uses in residential, commercial and industrial water purification processes.
