Type of Water Purifiers?
There are five types of water purifiers, depending on the purification method.
- RO Water Purifier
To purify water through reverse osmosis, a semipermeable membrane is used. The water pump pressurizes raw hard water to pass through the RO membrane. This process traps dissolved solids like arsenic, fluoride, lead, chlorine, nitrates, and sulfates in the RO membrane. RO water purifiers remove dissolved solids and chemicals from hard, salt water. Arsenic, fluoride, lead, chlorine, nitrates, and sulfates can all be removed by RO water purifiers. You can have safe drinking water with an RO water purifier if you have this type of water. Types of RO water purifiers: The type of RO water purifier depends on where it is mounted. RO water purifiers can be placed on a table or mounted on the wall. Under-counter or under-sink RO water purifiers. Undersink water purifiers are placed under the kitchen sink and hidden underneath. Wall-mounted or tabletop water purifiers are mounted on the wall or the kitchen table.
- UV Water Purifier
In addition to killing bacteria, viruses, and cysts, UV water purifiers have proven effective at killing microorganisms that cause waterborne diseases. This environmentally friendly technology did not use any chemicals during the purification process. In UV water purifiers, water is purified through UV lamp tubes. UV lamp releases UV light, which damages germs such as bacteria and viruses when exposed to UV light. Finding germs in water from dead bodies is still possible, but these are no longer harmful. Suitable for low TDS (Total Dissolved Solids) water such as lakes and rivers. UV water purifiers cannot treat hard water with a high TDS level. Like UF water purifiers, UV water purifiers do not remove chemicals like chlorine, arsenic, or fluoride.
- UF(ultrafiltration) Water Purifier
Ultrafiltration, or UF, uses hollow fibers of membranes made of a thin layer of material capable of separating water from other particles. When water feeds through water, UF membranes trap suspended solids, bacteria, and viruses. A major difference between UF and RO is that RO can block very minute particles, whereas UF blocks particles that are a little bit larger. Because UF water purifiers do not remove chemicals present in water, they only remove germs like bacteria and viruses from water when chemical contamination is low. Hard water does not work with UF. Water is as before and after UF treatment because dissolved salts are not removed.
- Activated Carbon Water Purifier
It is made from coal, coconut shells, nuts shells, and wood that has been broken down into small particles. It’s usually charcoal-activated carbon. Most pesticides and heavy metals are removed by activated carbon. Water tastes and smells better when activated carbon is added to it. Activated carbon is the most effective method to remove chlorine from water. Water is purified using activated carbon’s “adsorption” properties. The Activated Carbon surface sticks to whatever chemicals and metals are in the water during adsorption. Chemicals such as chlorine and other pesticides stick to the Activated Carbon as water passes through it, and the purified water falls into the lower storage tank.
- Sediment filter
Water purifiers like RO and UV are used in conjunction with this prefilter. Sediment is material that collects at the bottom of water or liquid. It removes the turbidity of water by eliminating rust flakes from metal pipes, sand, or mud particles. Sediment filters catch dust and mud particles present in water. Cotton and polyester are the two most commonly used fibers in sediment filters in some places. As shown in the following figure, sediment filters come in a roll shape and stay in a plastic-sealed container. The sediment filter is located just before the inlet to any other water purifier. Whenever dirt or dust passes through the sediment filter, it is trapped. An RO or UV water purifier is connected to the sediment filter’s water inlet as a water source.
