Why Reverse Osmosis?

Reverse osmosis is also one of the few ways that we can take certain minerals or chemicals out of a water supply. Some water sources have extremely high levels of natural fluoridation, which can lead to enamel fluorosis (mottled teeth), or the much more severe skeletal fluorosis (an actual bending of a person's bones or skeletal frame). Reverse osmosis can filter out fluoride, or other impurities, on a large scale in a way that a charcoal based filter (like the one most commonly found in homes) can't.

Quality of Reverse Osmosis Product Water

Quality of Reverse Osmosis Product Water

The amount of dissolved solids in water produced by reverse osmosis is approximately a constant percentage of those in the feed water. For example, when the feed water contains 330 ppm total dissolved solids (TDS), the product water may have 20 to 24 ppm (95% and 90% rejection ratio respectively). A RO system design is based on a certain range of feed water TDS, the percentage of rejection and percentage of recovery desired.

What is Reverse Osmosis?

Reverse osmosis is one of the processes that removes salt from seawater. Reverse osmosis uses a membrane under pressure to separate relatively pure water (or other solvent) from a less pure solution.

What's Osmosis?

Osmosis is a natural process. Osmosis is the passage or diffusion of water or other solvents through a semipermeable membrane that blocks the passage of dissolved solutes [source:Encyclopedia Britannica].
osmosis is when a solvent of low concentrated solute solution moves through a membrane to get to the higher concentrated solution.In reverse osmosis, the filter separates out solute from solvent, just reversing the process.

How Reverse Osmosis Works


Reverse osmosis uses a membrane under pressure to separate relatively pure water (or other solvent) from a less pure solution.The largest and most important application of reverse osmosis is the separation of pure water from sea and ground water 

When two aqueous solutions of different concentrations are separated by a semi-permeable membrane, water passes through the membrane in the direction of the more concentrated solution as a result of osmotic pressure. If enough counter pressure is applied to the concentrated solution to overcome the osmotic pressure, the flow of water will be reversed. (This takes about 50-60 bars of pressure [source: Lenntech].

Quality of Reverse Osmosis Product Water

The amount of dissolved solids in water produced by reverse osmosis is approximately a constant percentage of those in the feed water. For example, when the feed water contains 300 ppm total dissolved solids (TDS), the product water may have 15 to 30 ppm (95% and 90% rejection ratio respectively). A RO system design is based on a certain range of feed water TDS, the percentage of rejection and percentage of recovery desired. For a given system, the higher the percentage of recovery or the lower the percentage of rejection, the poorer the quality of product water becomes.

Is your water really clean?

WHY "SAFE ENOUGH" ISN'T "GOOD ENOUGH"


Nikki* woke up crying with a sharp pain in her abdomen. The next few days, her health deteriorated even more as she experienced bloody diarrhea, nausea, loss of appetite and fever. A trip to the doctor confirmed that she had amoebiasis, a type of stomach flu caused by a parasite. In more serious cases, this disease could even spread to the liver, lungs and the brain. The surprising culprit behind this illness? Water refills from refilling stations that do not meet high quality standards for potable drinking water.
Drinking water is essential to our survival and health. However, we should always be wary of the impurities and waterborne diseases present in it. When left unchecked, our drinking water could contain salmonella, cholera, e. coli and the Entamoeba histolytica, as was the case with Nikki.
To prevent contamination, water goes through treatment methods like reverse osmosis and deionization.
Surprising statistics on non-compliance by water stations
Although the different methods of purification remove bacteria found in water, we should also take into account how it is handled and where it passes through.
A 2013 study** showed that almost 80% of surveyed water refilling stations do not comply with Presidential Decree 856, the Code on Sanitation of the Philippines. The main reason behind this is failure to present an updated sanitary permit. Furthermore, an objective written exam was used to assess the workers’ knowledge on water sanitation in the context of a water refilling station. Exam results indicated that the respondents performed poorly on water sampling, the act of collecting water samples to be submitted to DOH-accredited laboratories and promotion of water sanitation and safety.
This is supported by a survey conducted by Pureit. A whopping 80% of the 313 surveyed water refilling stations do not implement the safety measures required to prevent water contamination via physical contact. Out of the 313 water refilling stations, 257 have no face masks, 264 have no scrub suits, 266 have no hair net and an alarming 301 have no gloves!
The same survey concludes that 35% of the water refilling stations fail to implement the correct procedure for sanitizing the water containers prior to refilling of drinking water. It comes as no surprise, then, that a lot of these stations operate without a sanitary permit or mandate set by the DOH.
With these numbers brought to light, it is now up to the Filipino households to equip themselves with additional cautionary measures and extra protection against water contamination.
Safe enough isn’t good enough
In this day and age, households should invest in a clean, reliable and safer source of drinking water.
According to the World Health Organization (WHO), “improvements in drinking water quality appear to be of significant benefit to health when improvement is secured close to the point of use – that is in the household.” (World Health Organization, 2008). Another WHO study, this one on the reduction of diarrhea in Guatemalan children***, has proven that in-home water treatment “successfully reduced diarrhea among all age groups but most importantly, it reduced it in the most vulnerable children, those < 1 year of age.” (World Health Organization, 2006).
Moreover, the United Nations Children’s Fund (UNICEF) also promotes household water treatment as an effective means of preventing waterborne disease. In fact, it is the answer to “its commitment by this year to reduce by half the people without sustainable access to safe drinking water “, one of their Millennium Development Goals.
With the use of in-home water purifiers, drinking water is directly treated right before it is consumed, thereby minimizing possible points of contamination. Courtesy - http://lifestyle.inquirer.net/

RO filters a threat to public health?

Experts suggest that regulations are needed to stop the unchecked use of RO, or at least the disposal of the stuff left behind after filtering. 

The reverse-osmosis water purifier at home seems to be a benign invention, allowing people to drink clean, healthy water. But now scientists are warning that rampant use of the RO technology could pose a serious threat to public health. One of the most popular water purifying technologies in India, the RO process is efficient in terms of filtering out toxic substances like arsenic and fluoride, especially in areas where groundwater is heavily contaminated. Simultaneously, though, RO systems, at both household and industrial levels plough back concentrated amounts of these substances back into the aquifers. Experts suggest that regulations are needed to stop the unchecked use of RO, or at least the disposal of the stuff left behind after filtering. “What we found with our survey is that industrial firms, like bottled-water ones, and households have no way out but to put it back into the soil and aquifers,” said Saradindu Bhaduri, Assistant Professor, Centre for Studies in Science Policy, School of Social Sciences at Jawaharlal Nehru University (JNU). The arsenic and fluoride-laden waste water generated by RO systems could have “adverse consequences” for human and animal health after it is dumped back into the groundwater aquifers, he told IANS. This could affect the population in the surrounding area which is dependent on this water source. “The waste water contains high amount of total dissolved salts like sulphates, calcium, bicarbonates and organic matter and higher concentration of arsenic and fluoride in areas where originally these elements were reported in ground water,” co-author of the study, Aviram Sharma of the JNU, said. Published on April 25 in Current Science, the survey report titled ‘Growth of water purification technologies in the era of regulatory vacuum in India’ also questions the absence of proper methods to dispose of the contaminated waste water. The research shows that bottled water firms of all sizes and classes, ranging from major multinationals to the vast majority of India’s 2,700 small proprietory firms, use RO-based water purification technologies in their manufacturing plants. The USP of RO-based system is that it can produce higher amount of filtered water with less supervision in comparison to methods like ion-exchange, explained Sharma. However, there is a drawback. During industrial use, waste water amounts to between 30 and 40 percent of the total water used. At the household level too there is a huge wastage. This can have a “disastrous impact” in water-starved areas due to over extraction of ground water, which is a major source of fresh water in most of the regions in India, said Sharma. Originally invented to make seawater potable, RO technology is being used in India without regulation. Most of the countries where the technology is used extensively, the feed water is primarily sea water or brackish water, according to the researchers. Namit Bajoria, Director, Kutchina, which entered into the water purifier market with an RO-based system, conceded that wastage was a concern. “It is like an equal and opposite reaction. 100 litres of water will give only 10 to 12 litres of pure water. So wastage is a big problem. But I don’t agree that it can cause harm to the groundwater. You are taking from it and giving it back,” Bajoria said. Bhaduri, however, says that “We have regulations for water quality but we don’t have regulations for the application of these processes.” He also said that more epidemiological studies were needed so that customers can make an informed choice. -- Courtesy Indian Express
