Comparing Commercial RO to Other Water Purification Methods
Water is a basic necessity in life, but not all types of water are safe for human consumption. Most people in the many regions of India have issues with the quality of water they use, and it is often described as dirty or unsafe. To do this, we must restore the water to its natural state so that people can use it safely to drink and carry out other activities. It is still possible to do this in various methods, and each generally have strengths and weaknesses. Among different types of water purification, the most effective one is the Commercial RO plant. But how effective is it in comparison to other approaches? Let us learn about each in detail and find answers to our questions.
What is Commercial RO and what is its role in water purification?
Commercial RO filters water by forcing it through a thin membrane layer. This membrane simply enables the passage of water; salt, chemicals and germs are not allowed to get through. It is a very efficient method of purifying water to make it safe to drink, particularly in cases where the water is highly salted or contaminated.
What makes Commercial RO Popular?
· Effective: It has been identified that there are very many commercial ROs which are capable of removing up to 99% of any unwanted compounds in water.
· Versatile: It can easily be used with many types of water including river water, well water or water from a borehole.
· Safe: Through a Commercial RO plant, the water that is produced is normally safe for drinking.
Other Water Purification Methods
1. Boiling
Water boiling is one of the methods that has been used in the past to treat water for use. In this process the water is heated till the water boils or reaches its boiling point. The boiled water is germ, bacteria and virus free and therefore there is no possibility of getting any diseases.
Comparison with Commercial RO:
· Effectiveness: Boiling water disinfects it yet it does not filter chemicals, salts or any other bad thing you get with Commercial RO.
· Cost: Cooking by boiling the food is cheaper and the most convenient way to prepare the food since it does not require fuel but gas or wood which can be expensive and/or difficult to obtain.
· Time: Water requires time to heat and once it boils one has to wait for a considerable amount of time for it to be warm before drinking.
2. UV Purification
The other method that is widely used is UV purification where water is treated with UV rays (ultraviolet) that kills any type of germs and bacteria. The UV light aids in purifying water since it alters the DNA of such disease causing organisms and hence water is safe for use.
Comparison with Commercial RO:
· Effectiveness: UV purification works effectively at germ and pathogen neutralization, however it fails to remove chemicals, salts or other contaminants as is the case with Commercial RO.
· Cost: UV systems may cost less than the Commercial RO plants to install but does not need electrical power for its working.
· Maintenance: UV lamps are consumable items that require replacement from time to time and less often Commercial RO membranes require some sort of maintenance.
3. Chlorination
Water chlorination is the method of putting chlorine in water to eliminate bacteria and germs. It is used in many water supplies of municipalities as one of the most popular techniques.
Comparison with Commercial RO:
· Effectiveness: Chlorination removes germs, but that doesn’t eliminate chemicals, salts, or heavy metals from water like Commercial RO.
· Taste: Chlorine treated water often has a bad taste and smell compared to water that has gone through an RO system which has a fresh taste.
· Health Concerns: While using chlorine will cause some health problems, Commercial RO does not have any of these problems.
4. Sand Filtration
Sand filtration is when water is passed through a layer of sand the dirt and particles stick to the sand and some bacterial also are removed. It is cheap and an easy technique, commonly found in use in the rural areas.
Comparison with Commercial RO:
· Effectiveness: Sand filtration is useful in the removal of sediments and particulate matters but is not equipped to handle chemicals, salts, or all forms of bacteria like the Commercial RO.
· Cost: Commercial RO costs more and is more complex than sand filtration, however, it does not filter water to the extent required as compared to Commercial RO.
· Maintenance: Sand filters need to be cleaned often, while Commercial are not cleaned as often but the process is more technical.
5. Activated Carbon Filtration
Activated carbon filtration involves the use of carbon filters through which water has to pass eliminating compounds in the process. Carbon has the capability to retain the impurities and at the same time helps in enhancing the taste and smell of the water.
Comparison with Commercial RO:
· Effectiveness: Activated carbon is suitable when it comes to getting rid of bad tastes, odors, and some chemicals but is not effective when it comes to the removal of salts, heavy metals or all germs as Commercial RO does.
· Cost: Carbon filters are cheaper but they should be replaced frequently while Commercial RO filters are a bit expensive but they have long service time.
· Use: This kind of filters is usually followed by some others as UV or RO to provide enhanced level of purification.
This makes Commercial RO to be the most desirable since people would rather wait longer to access safe water than take shorter time to get contaminated water.
Now that we have compared Commercial RO with other methods, it’s clear that Commercial RO has some distinct advantages:
1. Comprehensive Purification: Commercial RO effectively eliminates or reduces several impurities such as salts, chemical, heavy metals, and germs. This makes it one of the most effective ways of purifying water that is available in the market.
2. Versatility: Standard commercial RO systems have the capability to treat various forms of water makings it possible to be used in residential, commercial and industrial areas.
3. Quality: In most of the Commercial RO system, water quality is normally very good in that it is safe to drink with a very good taste. This is especially desirable for establishments such as restaurants and food processing companies where the water quality influences the prepared food.
Situations Where Other Methods Might Be Better
While Commercial RO is very effective, it’s not always the best choice for everyone. Here are some situations where other methods might be more suitable:
1. Low-Cost Needs: If you need a very low-cost solution and are dealing with relatively clean water, methods like boiling or sand filtration might be sufficient.
2. No Electricity: In areas without reliable electricity, methods like boiling, sand filtration, or chlorination might be more practical than UV or RO systems.
3. Specific Needs: If you are mainly concerned about germs and not other impurities, UV purification or chlorination might be enough.
Conclusion
Commercial RO is a very efficient way of purifying water that offers preventive barriers for waterborne contaminants. It is especially useful in environments with poor water quality or where high water quality is desired, such as in the commercial or industrial areas. However, there is something important that should be considered when choosing the method of water filtration.
Commercial RO is a perfect solution if you are looking for comprehensive and effective water purification technique. However, other methods such as UV purification, boiling, or activated carbon filtering could be more suitable if you require a less detailed, uncostly process or if given a certain issue such as germs or bad taste.
