Looking at the impurities available in water and the recurrent threats from water-borne diseases it is worthy of investing in a domestic water treatment plant and getting the water in purified form. Even in earlier times right from the Middle Ages, people had the concept of domestic water purifiers when they added camphor to the pitcher of water and chlorine at a later stage. However, as the impurities in the water level have increased, the earlier methods are no longer good and modern techniques of water filtration are required to filter out the impurities and make water healthy and drinkable.
The Different Types Of Filters
#1: Filters By Activated Carbon
There are certain harmful gases that remain soluble in water. These are gases like chlorine, ammonia, carbon monoxide, and nitrogen. There are some organic materials that remain suspended like rotten leaves, animal rot, and dead algae. Carbon has a nature that is porous in construction, and that helps to absorb the pollutants that come with water. A thin lining of silver that is activated covers the charcoal in household filters normally. This helps to kill the bacteria in water.
#2: Bio Sand Filters Are A Good Choice
A plastic or concrete box comes with layers of gravel and sand. These remove the micro-organisms which remain soluble and suspended in the water. Water is poured over the filter and gets collected in a container the impurities get accumulated in the upper layer of the sand and cleans the water that remains above. Thus water from the top layer is used for drinking purposes. The gravel and sand soak in the pathogens and particles and keeps them grounded to the lowest level keeping the water at the top free of impurities.
#3: RO Membrane
Filters that work with reverse osmosis are also called the RO plant when they work for homes or organizations. Tap water is collected and poured on the filter which passes through a membrane constituting a polymer film that has many small-sized pores. The pores help in clearing out the micro-organisms suspended in water. The impurities that are gathered are then let out through a pipe. If there are manufacturing defects or if the membrane develops larger holes due to use, the contaminants may pass on to the drinking water. Hence it is worthwhile to check the condition of the domestic RO plant and change the permeating membranes of the filter from time to time. The recommendation, however, is for places where the water content has high soluble minerals suspended in the water. However, the RO plant needs a fixed supply of water to function itself and ideally should be fixed to a water tap.
#4: The Ultra Violet filters
Low radiations of ultraviolet rays are passed over water to get rid of the bacteria and viruses polluting the water. These filters are best to remove the pesticides and can kill germs to the optimum level. The light rays can kill all types of bacteria but fail to remove suspended particles if any. Pure tap water where there are fewer particles can be filtered through the ultraviolet rays.
#5: Filters Made Of Ceramic
Ceramic filters come in the form of hollow-shaped cylinders made of Ceramic. The Ceramic can weed out the bacteria and separate the chlorine and bacteria that bilge the water. It is an excellent filter at a low cost to remove impurities.
The Ways To Buy A Good Filter
Every type of filter does not suit every location. It is better to get the water tested in a laboratory and get them to recommend the ideal type of filter that will be helpful to get rid of the kind of impurities prevalent in the water. Some filters are needed to get rid of the minerals dissolved that are harmful while others have high contents of pathogens, and yet another type has suspended particles. After getting the water tested, and reading this article, it will be easier to decide which kind of filter will be suitable for a particular location. Rather than focus on the cost, one should focus on the type that is particularly useful for a region and should look for the accreditation given by the FDA that is the Food and Drug Association or WQA which is the Water Quality Association of India. The certifications are the mark of a good make and robust composition and are more reliable than the cheaper ones available in the market.
A water purifier is a one-time investment that lasts many years if it is maintained properly. However, the same is necessary for ensuring good health, a good digestive system, and staying away from other health hazards. It is worthwhile to ensure that we invest well in the water filter and give some pre-thought before choosing which one to buy. Enjoy safe drinking and a healthy life and spend in a good and relevant water filter!
