Review Of RO Water Pufiers

Water purification systems are in great demand today. Factors such as climate change and pollution have made the water that we consume unfit for consumption.

The most important factor in a water purifier is the technology that it uses. The most used water purification technology is the Reverse osmosis (RO) purification technology.

Reverse osmosis is a proven technology that has been used successfully on a commercial basis. One of the better known uses of RO is the removal of salt from seawater. Reverse osmosis units remove many inorganic contaminants from household drinking water supplies. The removal effectiveness depends on the contaminant and its concentration, the membrane selected, the water pressure and proper installation.

The semi-permeable membrane used in reverse osmosis contains tiny pores through which water can flow. The small pores of this membrane are restrictive to such organic compounds as salt and other natural minerals, which generally have a larger molecular composition than water.

These pores also restrict bacteria and disease-causing pathogens. Thus, reverse osmosis is incredibly effective at desalinating water and providing mineral-free water for use in photo or print shops. It is also effective at providing pathogen-free water.

In areas not receiving municipally treated water or at particular risk of waterborne diseases, reverse osmosis is an ideal process of contaminant removal. RO systems are used in two applications - industrial and household water treatment

Advantages of RO System:

1. Very convenient for commercial usage, as a much higher percent of water is recovered.

2. Useful for places where there is a serious shortage of fresh water.

Disadvantages of RO System:

1. Water purified through only RO technology is distilled, has a bitter taste and has pH value lower than 7 which makes it slightly acidic.

2. RO technology uses a very fine membrane which has a pore size of 0.0001 micron. The process requires raw water to be forced at a very high pressure so that water passes through the small pores of the membrane, which blocks the bacteria, germs and other impurities from passing through. However, due to variation in day and night temperatures and high speed pressure, some of the pores of the membrane get enlarged after few months of continuous use, allowing harmful micro-organisms to easily pass through it, thereby making the process ineffective in the long run.

Kent has come up with mineral Ro technology that has all the advantages of Ro water purifiers but not the disadvantages. Kent mineral RO uses a combination of RO+UV+UF+TDS control system to provide the cleanest water possible. No wonder that it is being as the best water purifier in India.

A Peek At The Purification Industry In India

The purification industry in India is really flourishing. This can be attributed to the fact that pollution levels are at the peak today.

Air quality has steadily worsened in the past two decades in India, caused largely by rapid industrial growth, use of coal and growing urban traffic. A report by a Yale University research team showed that India ranked 174th of 178 countries in air quality, somewhere close to China and Pakistan.

Inhaling air that is this contaminated can lead to many diseases such as asthma and lung cancer. These factors have led to the increase in sales of air purifiers in India.

Pollution has also affected the quality of drinking water in India. The industries are a major factor for boosting the economy in a country. In developing countries like India, industrialization is encouraged and promoted. However, industrialization has its ill effects too, the waste from these industries pollute our water bodies.

Waste from industries include lead and chromium. The use of fertilizers and pesticides also pollute our water bodies. The chemicals in the fertilizers and pesticides seep through the soil and contaminate the underground water bodies.

Drinking water that is contaminated by such harmful contaminants can lead to numerous diseases. The use of water purifiers can ensure that these harmful contaminants are eliminated from your drinking water.

Based on the type of installation, water purifiers are of three types,

Gravity Based UF Water Purifiers

1) Wall mounted water purifiers
2) Table top/portable water purifiers
3) Under the counter water purifiers

Countering the problem of polluted water and air has become a business that can not be ignored. Many companies have jumped at this opportunity to provide clean water and air to consumers, among them Kent really stands out from the crowd.

Kent is widely recognized as a brand that relies heavily on technical superiority and customer satisfaction as their mantra for success. No wonder that they lay so much emphasis on research and development in the field of water purification. 

The Best Water Purification Method In India

Contaminated water is affecting the health of a lot of people in India. Diseases such as diarrhoea, cholera and other waterborne diseases are prominent among those who consume contaminated water.

Industries, use of fertilizers and pesticides, global warming and poor water transportation are factors that lead to contamination of water. To counter this grave problem, purification of drinking water is strongly advised.

We decided to shed some light on how to purify water.

KENT Water Purifier

1) Boiling: This is perhaps the oldest method used to purify water. Boiling water ensures that many diseases causing germs are removed from water. However, this method is ineffective on suspended impurities and metals like lead. This method also leads to pollution as wood or fossil fuel is burned to boil the water.

2) Chlorine: The use of chlorine to purify water is prominent among municipal corporations. The effect of chlorine is, however restricted to only a few contaminants. The use of chlorine also leaves a bad taste in the water.

3) UV based water purifiers: This method is very helpful in the process of eliminating microorganisms from drinking water. The UV rays emitted by these machines suspend the presence and growth of bacteria and viruses. However, many suspended impurities remain unaffected by the UV based water purifiers. To make the UV water purifiers more effective, it has to be used in combination with other water purification technologies.

4) Reverse osmosis (RO) based water purifiers: Probably the most known method of water purification today, RO based water purifiers are very efficient in removing contaminants from drinking water. The tiny pores in the membrane of the RO water purifiers blocks suspended as well as dissolved impurities. This technology also had a drawback just like the methods mentioned above.
The TDS in water remains uncontrolled and hence leaves a bad taste in water. You also require water at a specified pressure in this method to aid purification.

All the above mentioned technologies are efficient to purify water, but they also have some drawbacks. Kent, a brand that is committed to raising the bar of innovation in the water purification sector came up with a technology that has all the advantages of the above mentioned technologies but not its drawbacks.

The Kent mineral RO is a purifier that uses a combination of RO+UV+UF+TDS control to disperse the cleanest water. This innovative machine is capable eliminating both suspended as well as dissolved impurities while retaining the necessary minerals. This machine also improves the taste of water. With all its features, it is no wonder that Kent mineral RO is among the top 10 water purifiers in India.

All That You Need To Know About Air Purifiers

Government and scientists have had a lot of discussions regarding the outdoor pollution and how it should be controlled. However, not much emphasis has been laid on the quality of indoor air. The rise of diseases like asthma and other allergies has led to in depth research on the quality of air indoors.

Test have proved that the air indoors can be more polluted than the air outside. This may be because of the fact that homes or offices today are virtually sealed to make use of an air conditioner or heater more efficient. This stops fresh air to circulate inside.

Chemical contaminants like volatile organic compounds (VOCs) from office machines, carpets and furniture, and biological contaminants like mould, dust mites, bacteria and pollen are all cited as frequent causes of sick building syndrome.

These factors have led to increase in the process of air purification. Air purifiers for home not only

KENT Purifier

eliminate contaminants from the air indoors, they also remove odour from the room.

There are many air purification technologies present in the market ,but those based on the revolutionary Ozone disinfection technology in eliminating bacteria, viruses, fungus and other pathogens are more effective in the purpose of providing purified air.

The Ozone disinfection technology produces Ozone gas, an environment friendly and highly reactive oxidant, which is sprayed quietly and effectively through a fan. Air purifiers are available in two installation based variants; the wall mounted and table top types.

While air purifiers are certainly worth considering, eliminating the sources of indoor air pollution should be the first line of attack.  Make sure countertops, rugs, furniture, and other surfaces are kept clean. Do not let people smoke in the house.

If there are smokers in the family, strongly encourage them to quit.  Aside from being an irritant to people with asthma and allergies, the U.S. Surgeon General has warned that secondhand smoke can cause lung cancer, heart disease, and respiratory illness.

Things To Consider Before You Buy A Water Purifier

Unhealthy levels of contaminants such as bacteria, viruses, chemicals and dust can be found in water we consume. These contaminants are found in both tap water, as well as in water obtained from underground sources.

Bottled water is one of the easiest and quickest way to obtain clean drinking water. However, in the long haul, this can be a costly endeavour. A water purifier is a more effective and pocket friendly option. Water purifiers remove suspended as well as dissolved impurities from water. However, the effectiveness of a water purifier at removing specific contaminants depends upon the technology used. So, it’s important to know what needs to be removed from your water. Here is a peek at some of the technologies used to purify water before you buy a water purifier.

KENT - RO Water Purifiers

1) Carbon water purifiers: Does your water smell, or look dirty? An activated carbon (AC) can solve the problem. Carbon water purifiers, can remove pesticides, chlorine and other persistent chemicals. The disadvantage of a conventional carbon purifier is that, it cannot be trusted to remove salts, nitrates, nitrites, and some metals. Carbon filter amasses the impurities that have been removed from the water. The accumulated impurities might attract bacteria to breed in it.
2) Ultra Violet (UV) disinfection: This technology is also known as electronic boiling. This technology successfully deactivates harmful micro-organisms like bacteria and viruses, but fails to properly deactivate the more harmful ones - cysts. Also, if the water purified through this technology is stored for a long time, then there are chances that the deactivated micro-organisms may reactivate again. This technology is often combined with others to make it more effective. This technology, however, has no effect on dissolved impurities such as rust, arsenic, fluoride, etc.
3) Reverse Osmosis: This is the most used technology in the business today. If you want to remove organic chemicals such as metals (including lead), nitrates, asbestos, cysts and minerals, this technology won’t disappoint you. The only disadvantage of RO is that it strips the water of all its important minerals, including the essential ones that are necessary for our bodies.

If you note carefully, each of the above mentioned technologies have limitations. Does that mean that you will never get the cleanest water possible? Kent certainly disagrees with this one. Keeping in mind the disadvantages of RO and UV technology, Kent has invented a new technology called the KENT's Mineral RO technology. This patented technology has all the benefits of the RO technology, while eliminating its limitations.

KENT - RO Water Purifiers

This technology uses the innovative TDS (total dissolved solids) control valve allowing the user to retain essential natural minerals present in drinking water. It ensures that RO purified water does not have a bitter taste and the Ph level is maintained at around 7. It also enables the user to adjust the amount of TDS in purified water according to one’s taste.

This technology is based on double purification wherein water after passing through RO, is also passed through an Ultra Violet (UV) radiation and Ultra Filtration (UF). Secondary purification by UV/UF ensures that when the pores of RO membrane open up and allow harmful micro-organisms to pass through, they get deactivated/filtered out by UV/UF.

Safe Drinking Water - Current Scenario

We tend to take the availability of our drinking water as a right, and for a good reason. A lot of people in India, have access to drinking water than ever before. However, a question that arises is, how safe is our drinking water really?

This question is both timely and impervious, considering that numerous water borne disease have safe drinking water has been hampered by many factors; a few of them are listed below.

wrecked a havoc in the modern society. The availability of

1) Urbanization: The last few decades have witnessed a dramatic population increase. This has increased the demand for clothes, housing and food. As more cities and towns are being built, farmers have increased the use of fertilizers to produce more food. These fertilizers seep through the soil as contaminate water bodies. The increase in construction activities, increasing discharge chemicals from industries to produce more materials has also done a great deal of damage to our water bodies.
2) Untreated sewage: Sewage, garbage and liquid waste of households and factories are discharged into rivers and lakes. Harmful chemicals and toxins which make the water poisonous for aquatic animals and plants are present heavily in this untreated water.
3) Dumping: Dumping of solid wastes in water bodies causes huge problems. Waste includes glass, plastic, Styrofoam, etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals as well as contaminate the water, making it unfit for consumption.
4) Industrial Waste: Industrial waste contains pollutants like lead, asbestos, petrochemicals and mercury, which makes it extremely harmful to both people and the environment. Industrial waste is discharged into lakes and rivers by using fresh water, contaminating the water.
5) Oil Pollution: Sea water gets polluted due to oil spilled from ships and tankers while travelling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.
6) Acid Rain: Acid rain is caused when the air pollution mixes with rain. The acidic compound, which is a result of air pollution, mixes with water vapor and results in acid rain. This acid rain contaminates the water bodies making it unfit for human consumption.
7) Global Warming: Due to global warming, an increase in water temperature has been witnessed. This increase in temperature, results in death of aquatic plants and animals. This contaminates the water bodies.
8) Poor supply methods: Ageing pipeline network and poor maintenance results in municipal water getting contaminated by the time it reaches our homes.

The constant deterioration in the quality of water and rise in impurities, it is now imperative to have a water purifier in our kitchens, irrespective of the source of water supply. The current scenario is such that, water that is supplied by local government bodies or obtained from natural water bodies, are unfit for direct consumption. Water purifiers ensure that, the water we consume is free from impurities that may otherwise, be harmful.

Evaluating Home Air Purifiers

Air purification is suggested to patients with allergic and respiratory disease. Air purifiers have a cleansing effect on the environment. Air purification for a whole residence is possible thanks to home air purifiers.

According to estimates, people spend close to ninety percent of their time indoors in today’s world. To stay comfortable, more and more people have started using air-conditioners and room heaters.

To use a majority of these devices, one has to seal all doors and windows. Rooms are also sealed so that pollutants from outdoors do not enter. However, numerous pollutants like smoke, dust, pollen and animal dander are found indoors and overlooked often.

KENT -  Table Top Air Purifier

Studies suggest that, these pollutants cause multiple diseases and trigger allergies. Using a home air purifier ensures that the contaminants are neutralized. They eliminate viruses and bacteria inhibiting their growth. They also oxidize and neutralize chemicals, gases and cigarette fumes from the air.

The efficiency of air purifiers is based on one critical factor - The correlation between the concentration of particles in the air entering the device and the concentration of particles in the air leaving the device.

There are various technologies used in air purifiers such as electrostatic precipitation, mechanical filtration, etc., but the most efficient technology available, is the ozone generation method. This technology produces ozone gas, a highly reactive oxidant with the exceptional power to eliminate bacteria, viruses & harmful germs present in the air.

There are two types of air purifiers based on the type of installation.

1) Wall mountable air purifiers: As the name suggests, these air purifiers can be installed on the wall of your desired location. These devices are capable of purifying offices, conference rooms, restaurants and other large areas. They are ideal for rooms of upto 400 sq ft. Applications include neutralizing stale and foul odor and purifying the air; oxidizing and disinfecting chemicals, gases and cigarette fumes from the air; removing foul odors emanating from restrooms and bathrooms.

2) Portable air purifiers: These are devices with a compact and portable design. They are suitable for installation in homes, offices, living rooms, bathrooms or kitchens and ideal for rooms of upto 150 sq ft. They are also called table top air purifiers. They are designed to be used in single rooms or specific areas within the home. These systems are an option when a heating system is not conducive to a whole house cleaner, such as the case with a wood burning stove or fireplace.

While purchasing an air purifier, ensure that the brand you have chosen is approved and certified by a recognized and appreciated institute. Kent for example, has been certified by CE, a world renowned institution.
