We should always drink clean water, because dirty water can make us ill. The water that is collected from rain often contains different types of impurities that should be removed. All the impurities in the water do not drain by merely boiling it. By the process of boiling, the microorganisms in the water such as bacteria, virus or parasite are killed. But some of the impurities such as sediments, rudimentary particles, dirty particles, or chemicals do not vanish. If chlorine is added in the water, then some of the microorganisms are killed and the chemicals are also diluted. But, the water tastes bitter and produces smell. All the particles in the water cannot be filtered. When, the water is filtered some of the large compounds and tiny contaminants are washed away. Most of the impurities can be removed by distilling water, but this process is relatively slower.
Why people use water purifier at home?
Today, people should install water purifier to their homes because they can drink pure water. Pure water helps in easy digestion, removes toxins from the body, improves skin health and aids healthy brain function. The RO water purifier is used at homes because it removes several types of impurities from the water. The types of impurities present in water are chemical, biological and physical. Many people today use the RO water purifier because it is capable of removing salty substances present into the water also. It can even kill and extract different types of contaminants. It can remove the most dangerous germs from the water. The UV filter system is also not capable of removing salty substances from the water.
Water from bore wells and other sources
Usually, the water from the bore wells or sea water is salty and contains dissolved salts such as potassium and sodium. So, a person drinks salty water that is brackish. So, the RO filter can remove the salty substances from the water as it comprises a chamber. So, a person can drink pure water even if the water from the bore well or sea is so salty. If chlorine is added to water, then the water tastes bitter. So, even without adding any chlorine, the water is purified from the membrane. A person can drink pure water that tastes fine. The RO plant performs the osmosis process as the water flows naturally from the low solute area to the higher solute area. The RO system contains tiny membranes and they can even trap the bacterial impurities that are not visible to the naked eyes. They push the molecules of the water from the higher TDS level to the lower TDS level. External pressure is applied with the water pump and the flow of water is reversed.
Water purifier and its system
Today, many people use water filters, because it consists of various chambers to filer water. The RO system is popular today because it is one of the most reliable methods for filtration. Even sea water can be purified using this system. External pressure is applied to force water through the semi-permeable membrane to remove the contaminants from the water.
The water that is supplied from the tank is often not free from any type of pollutants. Different types of impurities are present in the water such as germs, sediments, metals; chemicals etc and they cannot be removed by simply boiling, distilling, using filters etc. So, many people today are using the RO purifiers. They remove all the contaminants of the water through the semi-permeable membrane. It improves the taste of the water and does not make the water bitter like the chlorine process. All types of contaminants are removed from the water. It consumes less energy compared to the other type of filters. It comprises different purification layers. So, it greatly helps in removing the taste of the water. The parts of the RO water filter system is valve, cold water line valve, shut off valve, flow resistor, drain line, pre filter, RO membrane, RO faucet, and storage tank.
Parts of the membrane and their functions
The check valve is located at the outlet and it restricts the backward flow of water from the storage tank. The cold line valve consists of a tube that is fixed to the inlet of the filter system. The drain line system allows the water to drain from the outlet and is used for removing the waste water. The RO membrane removes all the contaminants from the water and this drain line gushes away the waste water that is released from the membrane. The flow restrictor is used for controlling the flow of water from the RO membrane. They also help in controlling the pressure of the membrane. The cold water first flows towards the RO pre-filter system first. The carbon filter that is installed in the filter system helps in removing the foul odor from the storage tank. The water from the RO storage tank passes to the post-filter chamber and this water is used for drinking. The RO faucet system usually contains non-air gap models. The RO plant system in the filter is one of the most important parts. It removes all types of contaminants and dirty particles from the water. The water passing from this component usually transfers to the storage tank. The sediment filter removes the sedimentary and dirty particles from the water and hence the membrane does not get clogged.
Uses of osmosis system
The RO system is also used for neutralizing alkaline water. Although, alkaline water is recommended for people with excessive acidity system, yet it should be neutralized. So, the RO water purifier consists of parts such as UV or post carbon filters. The water is filled in the storage tank and this filter can be attached with alkaline filter system also. So, the alkaline properties can be removed and the water becomes neutralized. This water is fit for drinking.
Some of the parts of the filter system should be changed. If the water is getting clogged, then the sedimentary particles do not drain away and hence pure water is not available for drinking. Then this part should be replaced. If this part is not quickly replaced, then the dirty particles
