Today, many people use water filters that provide 100% pure water. The water purifier contains some chambers and different filter systems that can filter different types of particles or sediments. They can remove the most toxic chemicals and substances from the water that cannot be removed by other filter systems. The process of installation of RO filter system is easy and simple. The water from bore wells, sea, rivers, groundwater, rainwater etc is not pure and often contains some impurities that are harmful to mankind. Many people are using RO water purifier because the water that is supplied by the municipality or tankers is not 100% pure. Some of the microorganisms present in the water are cysts, bacteria and viruses. They also contain certain dissolved impurities such as lead, arsenic, minerals, salts, calcium, iron, or magnesium. Before installing a RO system, the users should consider some points.
Sources of water
TDS in simple words mean ‘Total Dissolved Substances’. So, the water s extracted from the underground sources contains high level of TDS. A person need not necessarily install the RO system. The TDS can be checked with the TDS meter. If the level of TDS is higher than 500 ppm, then the person can install purifier to the homes. The water is supplied by the municipal corporation. The water that is supplied by the municipality usually contains lesser TDS. So, such people should not use the RO system because the essential salts and minerals in the water can be extracted.
But while purchasing the RO water purifier system, the user need not check the TDS level of the input water.
Electricity
The RO system is an electrical appliance and due to constant power shortage, the functioning is affected. So, the people living in areas with poor electric supply should not preferably install this system.
Water pressure
The level of water pressure should be 5-40 psi so that it works effectively.
The RO water purifier can be installed only by experts. Usually a well-trained engineer installs this system. They also help in uninstallation of purification of water purifiers. The spare parts should not be damaged in the process of installation and un-installation. A person should preferably buy a purifier that is reliable, durable and cost-effective. Usually, the cost of installation is not included in the process of installation. Most of the purifiers are available with some installation service. Usually, some of the RO filter system performs 3-stage purification process. They perform the reverse osmosis process to kill microorganisms such as bacteria, or viruses present in the water. The RO filter system usually contains a large storage system so they can store the water even if electricity is not available.
Process of installing the RO water purifier system
The process of ro installation is usually done by certified engineers. The process of installation of RO water purifier system is complicated because this system contains many parts. The installers require many tools to install the RO system such as electric drills, screw driver, adjustable wrench, hammer and center punch, Teflon tape, drill bits, plastic tubing cutter etc. The plumbing steps should be completed and a licensed plumber is also required. Usually, the sprayer in the sink is disconnected for installing the faucet. Then a mounting hole is made for the faucet and then it is positioned. Then the porcelain or cast iron is installed and then the faucet is mounted. The threaded shank is fed through the sink hole and the lock washer is slid and then the wrench is tightened. Then the tubing installation process is performed by building the angle stop valve. Then, the drain-saddled valve is installed and a wastewater connection is made. The under sink installations are made and then RO unit is mounted to the sidewall of the sink cabinet. The RO components are installed and the RO unit is mounted to the side of the sink. This unit is installed usually at the front side of the cabinet. Then the supply tank is placed and finally the tubing connections are made. The tubes are cut to the suitable lengths and crimps are not made to the tubing’s. In this way, before using the system, different parts such as fitting connections, ball valves, valves on bladder tank and the open faucets are inspected. All the parts are assessed so that they do not cause any leakages.
Parts of the RO system and their functions
The RO water filter system contains some important parts such as sediments pre-filter, activated carbon pre-filter, RO/UF membranes, display, UV filter, storage tanks and the display system. The carbon post-filter is also a polisher and it improves the taste of the water. It also helps in removing any toxic materials from the water. The display system consists of some special features such as on/off tank, full etc.; these parts contain some of the important parts such as membrane change, fault alert, indicator, purity indicator etc.
The conditions for installing these electric water filters should be optimum. Usually, such systems are heavier and they cannot move from one place to another easily. This should be preferably placed in the kitchen. The person should install inlet for electricity. These filters can be simply used and they contain sediments or particles and some undisclosed impurities also. So, the faucet tap filters or gravity purifiers are used in the process. During the RO installation process, the parts are accessed by the installers again if they are properly fitted.
The water contains some of the common impurities such as dissolved organic salts, potassium, sodium, or dissolved inorganic compounds such as magnesium or calcium. They may also contain biological impurities such as viruses and bacteria. Due to organic compounds, they produce foul smell. So, by drinking impure water, a person can experience different types of waterborne diseases. So, the RO chamber performs the function of pushing level of TDS to the region of lower TDS. So, external pressure is applied by using water pump and hence the flow of water is reversed. They push the water molecules from the semi-permeable membrane to the other side of the membrane and hence the dissolved liquids and impurities are trapped. The RO waste water is discharged from a different outlet. If the TDS level of the water is higher, only then the person should purchase the RO system.
