REVERSE OSMOSIS – A POTENTIAL TECHNOLOGY OF WATER PURIFICATION
The full form of RO represents the term ‘reverse osmosis’. This word has a deep connection with the water purification process. So, if you are planning to buy an efficient water purifier, then you must know the reverse osmosis concept.
HOW THE CONCEPT OF REVERSE OSMOSIS RELATES TO WATER PURIFICATION?
When you try to know what reverse osmosis is, at first you should understand the theory of osmosis. Every liquid has a significant characteristic to flow from lower concentration towards higher concentration. Water is not also exceptional from this tendency. While the plants absorb the water through the root, it is the best example of osmosis.
The exact opposite theory of osmosis defines the concept of reverse osmosis. According to this theory, the flow of liquid remains in the direction of high concentration to low concentration.
Based on this opposite theory of natural tendency, the water purification process is executed. A thin cloth-like membrane divides the space of water purifier into two categories high-concentration and low-concentration. This membrane is semi-permeable in nature.
In the entire process of reverse osmosis, this semi-permeable membrane plays a vital role. These membranes allow only the solvent molecules but not the specific solutes. This definition of solvents and solutes is defined on the sizes.
Here the whole process of reverse osmosis has a similarity with some windows net of houses.
The window net allows air but does not recognise a tiny insect. Similarly, the semi-permeable membrane acts in a water purifier. Reverse osmosis is a useful theory of separating the pure water solvents and harmful contaminants.
WHAT ARE THE CORE ASPECTS OF REVERSE OSMOSIS?
In any standard process of filtration, it is mandatory to remove the impure molecules, collected on the media filter. Only after that, it becomes reusable. So, this protocol of purification is involved with maintenance steps. But the specific theory on which the reverse osmosis based water purifier works does not need any maintenance. This innovative concept is called cross filtration.
Water purifier requires two outlets to execute this concept. One is for flowing pure water and another outlet for keeping the eliminated solutes mixed contaminated water. In this rejected water, 93% to 95 % impurities exist. The level of contaminants is very high in this rejected water. So, it is hazardous for drinking. The consumers can use this water in cleaning floors and toilets.
So, the theory of reverse osmosis makes purification systems efficient as they can remove the highest percentage of total dissolved salts in water. In general terms, RO filters do not allow the pollutant molecules having weight more than 200.
A Reverse osmosis based water purifier also blocks ions having higher valency. RO filter allows sodium due to its monovalency. So, to eliminate these micro-ions, RO filters require the incorporation of supplemental filters.
Any form of metallic pollutants does not get allocation passing through reverse osmosis theory-based water filters.
WHAT ARE THE ESSENTIAL COMPONENTS OF A REVERSE OSMOSIS BASED WATER PURIFIER?
During buying an RO water purifier, the consumers should have explicit knowledge about the components of this device. The following points discuss the efficient functional parts of a Reverse Osmosis based system.
It is one of the simple potential portions of the RO device. In the middle point, between the water supply line and reverse osmosis device inlet valve exists. It executes the first phase of the process of the RO filtration system.
It plays a vital role in directing the flow of the liquid into the system through the main supply lines. So, in reality, inlet valves supply pollutant-rich water. The inlet valve, being connected with the main water supply tank, pushes the contaminated water to the purification device.
FLOW PREVENTION VALVE
The design of the inlet valve is too specific. So, it plays only the role of giving the entry of water from the supply line to the reverse osmosis system. But according to practical situations, water has its pressure during entering from the supply line to the RO system. Now in terms of intact flow management, a separate valve exists to prevent any kind of damage of the inlet valve. Because, if the backflow of the water supply line damages the inlet valve, then it causes the reduction of system pressure.
So, to maintain the pressurised system of reverse osmosis devices, this check valve exists. It ensures the hindrance-free water flow into the RO system.
Entering into the core area of the reverse osmosis system, through the two connective valves, the liquids face an initial filtration. This preliminary phase of filtration ensures the removal of solid contaminants like sands and grit. The primary purpose of initial filtration makes overall filtration effective.
Before the execution of a sensitive filter sequence, it eliminates all the large molecules of contaminants. Thus it reduces the stress on the primary membrane filter.
REVERSE OSMOSIS MEMBRANE
After crossing the phase of preliminary filtration, the water enters into the reverse osmosis membrane. It executes the primary filtration methods to make the water safe for drinking. After passing through the pre-filter parts, the water looks clean at a glance. But it needs to go through more in-depth purification processes.
RO membrane caters that purpose of the complete elimination of liquid dirt molecules and also microscopic particles. Different category of RO membrane is available in reverse osmosis based water purifiers. Some of them act to eliminate harmful particles along with chlorine. But only very few of them remove other molecules except chlorine.
This inherent part plays the role of picking up the impure molecules from the accumulated substance of the membrane. Then it flashes out all the pollutant particles through the drain line. It is connected with the wastage pipe directly.
FLOW PUMP OR RESTRICTOR
One of the essential parts of a reverse osmosis based water purifier, flow restrictor plays a potential role. This feature exists at the draining system line just after the thin membrane. It executes a flow controlling mechanism. If you go through the overall featured design of a purifier, then you must understand how it decreases the amount of waste of water.
It also reduces the extreme stress on pressure-led technology in case of water discharge.
A reverse osmosis based mechanism requires a flow restrictor to ensure the smooth performance of the RO water filter. Thus, a flow pump or flow restrictor determines the purity of water. Because, as per expert’s opinion, too much pressure can interrupt the purification level of the RO system.
After the execution of an intensive purification mechanism, clean water reaches into a tank. With the aid of a pressurised holding system this tank stores clean water till the opening of the faucet. Here a potent mechanism of two bladders works to manage the entry and exit of the clean water. In storage, pressure always exists.
In the lower portion of the tank, a pressurised air-filled ladder exists. And at the top part of it, a full water bladder is featured. As the faucet opens the water comes out by the forces of the air pressure. And the users can get a clean stream. At that moment the inlet valve also opens to get more water. Thus, the amount of pressure becomes spontaneous, pushing the water to come out.
FINAL PURIFICATION FILTER
Above discussed all the processes to make water clean. The users can drink it safely. But in this stage, while users collect it from reverse osmosis water purifiers, sometimes they get an unpleasant smell. So, the clean water needs to pass through one last purity protocol. And that is a carbon filter.
For the complete extraction of odour and unpleasant taste, carbon filter removes the residue of the clean water. Thus, by the removal of the leftover, this filter restores the ultimate natural taste of the water.
At the endpoint, there is a faucet. With a single tap, the users of the reverse osmosis purifier get control over the clean stream feed.
IS REVERSE OSMOSIS A PRETTY OPTION FOR DRINKING WATER?
For a long time, reverse osmosis purification method supplies safe drinking water in our house and business arena.
So, yes, you can depend on this potential water purification system. Now, take a look at the following valuable reasons why you should buy RO water purifier:
NO FEAR OF ODOR AND UNPLEASANT TASTE
See, we are not saying that reverse osmosis filtration is only one step based purification as it executes a multi-layered purification mechanism to provide clean water to its users.
But we must say a hundred per cent removal of different kinds of molecules requires a secure mechanism. Moreover, RO water purifier ensures the complete satisfaction of the users. So, you can expect complete contaminant-free water without odour with a natural taste.
AVOID DRINKING WATER CRISIS
With a RO device, you can say no to the local water delivery service. As these kinds of services sometimes create a drinking water crisis for you with an undeclared delay. The reason for the delay can be anything such as traffic, natural disaster, strike and more. Ultimate suffering is yours. So, buying reverse osmosis based reliable water purifier is always a smart option for you.
The robust mechanism of the RO system always fights against rigid types of contaminants. It also comes with efficient components to face any local conditions of the water. But the part of any device needs maintenance to boost the optimum performance. Here, membranes execute the most critical phase of filtration. So, to keep intact the overall mechanism of reverse osmosis water purifier, a periodic replacement is best.
The life-span of a membrane is 2-3 years. And to keep the taste of the water natural and odour-free, carbon-filter requires replacement in every 6-9 months. So, the users can expect minimal maintenance hazards for the RO purifiers.
A reverse osmosis based purifier has a prominent capability to deal with different types of contaminants. After installing a RO device, it resolves all your worries based on pollutants. RO filters remove from nitrates, fluoride, bacteria, sulfates, pesticides, arsenic to chloramines and chlorine.
All these reasons make a RO purifier one of the best solutions for safe drinking water.
