Understanding Reverse Osmosis (RO). How RO Systems Work and What They Do.

1. Why Choose Reverse Osmosis Water Filtration System?

Fresh Delicious Water 

RO filtration improves the taste and appearance of water and eliminates odour by removing all the chemicals, debris and contaminants that cause such problems.  

Saves your money

With an RO system, you will no longer need to arrange for delivery service and stop purchasing bottled water altogether. You will always have premium quality freshwater within reach for just pennies per gallon.

Easy Maintenance

With very few parts to be replaced, maintenance and cleaning of RO systems is a simple task.  

Removes Impurities 

RO systems remove pollutants from water including nitrates, pesticides, sulfates, fluoride, bacteria, pharmaceuticals, arsenic to name a few. The Carbon filter also removes chlorine and chloramines.

Installed at the kitchen sink:   

An RO filtration system is installed at a single water connection and thus is called a point of use (POU) water filtration system. It can be installed on a wall or inside the cabinet under the kitchen sink. It can also be connected to the fridge and/or ice machine.

2. How Does Reverse Osmosis Work? 

Reverse Osmosis is essentially a simple Water Filtration Process in which dissolved inorganic solids and impurities are removed from a solution, ie water.  

 This is accomplished by household water pressure pushing the tap water through a thin semi-permeable membrane with small pores that only pure water can pass through, while larger particles such as impurities and bacteria are rejected.

A few impurities Reverse Osmosis filtration technology can remove:

Fluoride

Lead

Chlorine

Chlormamine

Pesticides

Detergents

Nitrates & Sulfates

What about the Contaminants That Don’t Pass Through the Semi-permeable Membrane?   

Ro systems incorporate 5, 6 or 7 stages including the semi-permeable RO membrane. When water from your household main line is pushed under pressure through all the stages, the impurities are filtered out and flushed down the drain. Leaving clean and fresh drinkable water in the tank for your use.

What are generally the main components of a Reverse Osmosis System?   

Note that although most RO systems look similar and work basically the same way, they differ in the QUALITY of their components.   

  1. Cold Water Line Valve: This valve is fitted onto the cold-water supply line on one side and has a tube on the other side that attaches to the inlet side of the RO system prefilters. This is the connection with a water source for the RO system.   
  2. Pre-filtration:  Water from the cold-water supply line enters the Reverse Osmosis system Pre-Filters. There’s typically more than one pre-filter used in a Reverse Osmosis system. The most commonly used are sediment and carbon filters. These pre-filters are used to remove sand, dirt, and other sediments that whereas carbon filters are used to remove chlorine. These filters can be perceived as the army protecting the System from impurities that may clog it and/or chlorine which can damage the membrane.   
  3. Reverse Osmosis Membrane: The Reverse Osmosis Semi-Permeable Osmotic membrane is the core of the RO system. It is a barrier for a variety of organic and non-organic contaminants dissolved in water, heavy metals, radioactive and carcinogenic elements. It only allows water in, as its porosity is the size of water particles, that is 0,0001 micrometers.  
  4. Post-filtration: When the treated water leaves the pressurized RO tank, it goes through the final stage which is the Postfilter(s); right before it reaches the RO faucet. This consists of Granular Activated Carbon filter(s) to remove any remaining taste or odour. A 6-stage RO system would include a mineralizer cartridge to dissolute water and in turn, improves the taste and smell of water.  
  5. Automatic Shut Off Valve (SOV): The RO system has an automatic shut off valve to conserve electricity and water. This valve automatically closes when the storage tank is full to stop water from flowing through the membrane and down the drain. Once the RO faucet is switched on and water flows out, the pressure in the tank drops causing the shut-off valve to open in order to allow the purified drinking water to flow through the RO membrane while the wastewater is diverted towards the drain.   

      7. Flow Restrictor: Located in the Ro drain tubing; the main purpose of the flow restrictor is to regulate the flowing water in order
to maintain the flow rate required to obtain premium quality drinking water. It also helps to maintain pressure on the inlet side of the
membrane to force more water to flow into the membrane and thus get treated

        8. RO Storage Tank: Treated water leaves the Osmotic membrane go into a pressurized storage tank. The standard RO storage tank holds                 from 2 - 4 gallons of water and has a bladder to keep the water pressurized
        9. Faucet: The RO system comes with its own faucet, which is usually installed on the kitchen sink. 
       10.Drain line: This is a tube that runs from the outlet end of the Reverse Osmosis membrane housing down to the drain, disposing of the
wastewater containing impurities and contaminants that have been filtered out.

3. How does a Reverse Osmosis Membrane work?

There Are Generally Four Stages In The Reverse Osmosis Process:  There are 4 main stages in the Reverse Osmosis Process: 

FIRST STAGE: SEDIMENT FILTER:   

Designed to strain out sediment, silt, and dirt and has a double purpose as it not only filters out sediments but also prevents dirt from getting to the delicate RO membranes which can damage it.  

SECOND STAGE: CARBON FILTER:   

Designed to remove chlorine, poisonous compounds, organic/ mechanical impurities and other contaminants that affect the performance and lifespan of the RO membrane as well as improve the taste and odour of your water.  

THIRD STAGE: REVERSE OSMOSIS MEMBRANE:   

Designed to allow only water molecules through (0.0001 micrometers); filtering out almost any contaminants  

 

FOURTH STAGE: POST- FILTER (ALSO KNOWN AS POLISHING FILTERS):   

The final post filter (carbon filter) improves taste and odor in the water to ensures that you’ll have optimum quality drinking water.   

Do you know that 7 litres of water are required to generate only a 1-litre bottle of water? And that this bottle travels thousands of miles to reach the consumer?

Buying a bottle of water is an easy drink choice, but if you read on the life journey of a bottle you’ll most probably be unpleasantly surprised!

Billions of Plastic Bottles Are Produced

Natural gas and crude oil (from petroleum) are extracted from the deep ground and then transported to a refining unit; also known as chemical processing plant, which generates PET Pellets (scientifically named as Polyethylene Terephthalate) through a complex procedure. These micro pellets are then heated, melted and then bottles are produced in all shapes and types using a blow-molding technology.

Some types of plastic bottles are designed to be soft/ flexible, whereas others are made to be tougher. Every bottle production factory requires a huge amount of energy and water to produce clear commercial bottles. Additional materials such as paper, thin plastics and ink are also required for the bottles’ labels and packaging.

In addition to the 7 litres (of water) necessary to produce a single bottle of water, the amount of water that actually ends up inside the bottle has had to travel for a long journey from its natural origin. This may include ship or truck carriers, which emits toxic carbon fumes.

Plastic Bottles Are Worldwide Champions

By the time the bottle is filled with water, labelled and placed on its shelf, it then takes off on its journey to its final destination before reaching the hand of customers, whether it’s a mini market, supermarket, café or a vending machine.

The approximate distance a bottle of water travels varies based on the brand/company you’re purchasing it from. A bottle of Fiji, for example, has a journey of thousands of miles to reach stores in the U.S or Europe—likewise. A bottle of Evian may be carried through a cargo ship from France to the opposite corner of the globe e.g Australia. Needless to say that the cost of these procedures is tremendously high, and is the reason why you end up paying100X the price of its counterpart regular tap water.

Plastic’s longevity

By the time you finally sip some water, the bottle you hold in your hands would have travelled through multiple spots across the globe, yet you might be surprised to know that its journey has just started.

Fortunately, a portion of plastic bottles may end up in a sorting unit, where they go through a recycling and conversion process into other types of plastic products. However, most will be dumped in a landfill and left for 450 to 1K years to decompose naturally.

If we take into account the fact that 70 billion gallons of water bottles are purchased every single year, the image of the piles of plastic is quite horrific.

So, are there any alternative choices to bottled water?

People fancy purchasing bottled water for its taste and convenience, but luckily the alternative is much more convenient, and the water quality isn’t any less, if not even better!

By installing a water filtration system at home or in your office, you can purify the composition of water without the need for perishable plastic bottles. Not only will you trim down cost but also the long-term toxic effect of using disposable plastic bottles.

Reusable plastic/ glass bottles are a healthy option you’ll enjoy, especially the ones with infusers, to add a zesty citrus taste or fruity delight.

One thing to take into account is that not all water filtration/purification systems are deemed equal. Some are bulky, require a lot of space, and don’t blend with our modern energy-savvy homes.This is the reason why we have created Permatech German Engineered Filtration and Purification Systems with compact and modern designs to save you money and time and generate a continuous supply of optimum quality, crystal clear, refreshing water that you can trust, for you and your loved ones.
