Alkaline water has changed the lives of millions of people around the world. Water filtration is the process of removing unwanted chemicals and also the biological contaminants from water. Generally water is purified for drinking purposes, but can also be purified for other purposes like to meet the medical and industrial use. Water filtration is a physical process of purifying drinking water and it is normally a common method used by the majority of people. Drinking water is normally purified to reduce the concentration of unwanted components like suspended particles, bacteria, fungi etc that might be harmful to your health.
You cannot gage whether or not water is of good quality just by visual examination. Boiling or filters are not enough for water treatment and all the contaminants that might be contained in it. Not all water is healthy water; therefore you must take proper precaution in ensuring that you drink treated water for it is good for your health.
There are various ways of treating your water; one of them is by pumping and containment. For majority of water it should be pumped from the source or aided into pipes or storage tanks. These physical infrastructures meant for holding water should be constructed using appropriate materials so as to avoid adding the contaminants to the water again.
Distilled water normally has a pH of 7.0 (neutral), it is neither alkaline nor acidic. Water pH is used in determining the acidity of the water whereby sea water has a Ph of 8.3 which is slightly alkaline. Acid water is lower than pH 7.0 and thus lime or soda ash is normally added to increase the pH. Of the two, lime is more common since it is cheap, but it also makes the water hard. The water should be made to be slightly alkaline so that coagulation and flocculation work effectively and also help in reducing the risk of lead being dissolved from lead pipes.
Filtration is the final step in getting rid of the remaining suspended particles and unsettled floc in your water. One of the common water filters is the rapid sand filter which allows water to move vertically through sand which has a layer of activated carbon or anthracite coal on top of the sand. When cleaning this type of filter, water is run quickly upwards through the filter, in the opposite direction. This method of cleaning is commonly referred to as backflushing or backwashing.
