5 & 6 Stage Reverse Osmosis Water Filter Purification Systems
Reverse Osmosis Water Purification Systems 5 & 6 Stage
Reverse Osmosis is a technology that is used to remove the large majority (98%+) of contaminants from water. It is particularly sucessfull at reducing the high levels of manganese present in water. The Reverse Osmosis system works by pushing the water under pressure through a number of increasingly smaller filters and finally through a semipermeable membrane, essentially trapping all contaminants. Reverse osmosis is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and remove larger particles from drinking water. These reverse osmosis systems are typically used in kitchens to remove impurities and give pure water in a domestic application. Traditional 5 stage pod type and 6 stage or compact versions are available pumped or non pumped.
So what is a reverse osmosis water filter?
Reverse osmosis is a water purification process that uses a semi-permeable membrane (synthetic lining) to filter out unwanted molecules and large particles such as contaminants and sediments like chlorine, salt, and dirt from drinking water. In addition to removing contaminants and sediments, reverse osmosis can also remove microorganisms – which you certainly do not want to drink. It gets water clean down to a molecular level, leaving only pure water behind.
How does reverse osmosis actually work?
In reverse osmosis, an applied pressure is used to push the water from high concentration of contaminants to low concentration of contaminants. Water is forced in reverse and the contaminated water is trying to move into the pure water, but because it must pass through a filter first, the contaminants get trapped and only the pure water passes through; resulting in the cleanest possible drinking water.
Where do you put the reverse osmosis purificationsystem?
They are typically used in kitchens to remove impurities and give pure water. A modern tap and fittings are also supplied.
Why would I install a reverse osmosis system in my home?
Not only does our drinking water have contaminants in it, but fluoride and chlorine are also added. This can make our drinking water smell strongly and distasteful. By installing a reverse osmosis system you have great tasting drinking water. This means no more bottles water, better tasting food, tea and coffee. This can be used for baby making formula also.
How do I maintain my reverse osmosis system?
To keep your water as pure as possible, the filters in the system will need to be changed on average every 6-12 months, depending on usage, this can be scheduled maintenance and we can take the.
How long will a reverse osmosis system last?
If your reverse osmosis system is regularly serviced and the filters are changed on a regular basis, the system should last up to 10 years.

Important Information:
Reverse Osmosis systems waste water to make water, this is normal and the same with all RO systems as this is the way the membrane rejects the impure water, which goes to drain, to produce the pure water. This process requires high water pressure as the ‘permeate’ water is being forced through microscopic holes in order to catch contaminants.
These systems require a minimum of 29 PSI / 2 Bar (Pumped RO Systems) or 45 PSI / 3 Bar (Unpumped RO Systems) to work. Ideal pressure depends upon incoming water temperature but around 60 PSI (4 BAR) is acceptable to produce pure water. We will always recommend purchasing an RO system with a booster pump pre-installed as this allows you to easily configure water pressure.
Membrane performance is dictated by several variables, most notably; incoming water TDS, pressure, and temperature. In order to achieve the 50GPD output stated the incoming water must match the test conditions which are; Concentration of Permeate (NaCl) = 250ppm, Water Pressure = 60 psi / 0.41MPa / 4.14 Bar, Temperature = 25°C
Because mains water is typically colder than test conditions we recommend that these systems are run at, or around, 80 – 90 PSI (5.5 – 6 bar). This allows the system to reduce the wastewater to pure water ratio and work quicker at producing pure water.
As many people won’t have this mains pressure; pumped RO Systems or booster pumps can be purchased from us and added to the system which will increase the pressure output (a minimum of 29 PSI (2 bar) is required to operate the booster pump).
The membrane elements must be stored in a cool and dry place, away from direct sunlight. Do not expose to temperatures above 45°C
The membrane can last between 1 and 2 years depending on incoming water hardness. Filters must be replaced at least every six months for optimal performance.

WATER SOFTENERs
Fitting a domestic water softener will reduce scale or hardness giving you all the benefits of soft water. Scale builds up in pipes, boilers, washing machines and dishwashers. Fitting a water softener reduces this scale, saving money, lengthening the life of appliances, reducing scale deposits around showers and taps, making laundry feel softer and reducing the use of detergents and other chemicals. Timed controlled models regenerate automatically every 2 or 3 days. Meter controlled versions monitor the amount of water used to regenerate when it needs to.
How do I know if I need a water softener?
If the area you live in has hard water then, the chances are , you will benefit by installing a water softener. Some signs of hard water are staining on your sinks, toilets and bathtubs, limescale buildup on shower heads, kettles along with inside your washing machine, dishwasher and shower pumps. Lime – Water dissolves lime into itself as it passes through rocks and soils. Water which contains dissolved limestone is said to be “hard”. When this hard water is heated the lime reverts back to its solid state, i.e. limescale, causing scaling problems in Kettles, Showers, Dishwashers, Washing Machines, Immersion Heaters, Central Heating, Hot Water Pipes, etc. It makes them less efficient and they need to be serviced or replaced much more frequently. In addition to all this the scale makes it much more expensive to heat the water with a scaled up element poorly transferring the heat through the water. Hard water makes soap and laundry detergent less effective and can make your skin and hair dry.
What is hard water?
Hard water is water that has a high mineral content while percolating through rock which has deposits of limestone, chalk or gypsum. The higher level the mineral content, the harder the water. Hard water is very common in Ireland.
Can I test for hard water?
Yes, you can now buy home water tests to see how hard your water is. Generally, the following table will tell you how hard your water is:
Classification
Soft
0 – 17.1 Mg/L or ppm / 0 – 1 Grains per Gallon (gpg)
Slightly hard
17.1 – 60 Mg/L or ppm/ 1 – 3.5 Grains per Gallon (gpg)
Moderately hard
61 – 120 Mg/L or ppm/ 3.5 – 7.0 Grains per Gallon (gpg)
Hard
121 – 180 Mg/L or ppm/ 7.0 – 10.5 Grains per Gallon (gpg)
Very hard
180+ Mg/L or ppm/ 10.5+ Grains per Gallon (gpg)
What are the benefits of installing a water softener?
By installing a water softener in your home you will see the following benefits:
- 100% limescale removed
- Washing machine works better with less detergent
- Hair and skin is softer
- Longer life on appliances such as kettles, dishwashers, washing machines and electric showers
- Helps saves on energy bills as water pipes are not clogged and hot water cylinders last longer. Also saves money on soaps and detergents as less are needed with soft water.
- How long do water softeners last?
- The average life expectancy is about 10 – 15 years depending on the system you purchase.
WATER softeneR Frequently asked questions?
Is it OK to drink softened water?
Generally, yes, softened water is okay to drink by healthy people but does contain a small amount of sodium. The harder the water that was softened, the higher the sodium content. People who are on a low sodium diet and babies should not drink softened water. If installed correctly, there should be one tap that is from the mains directly and not run through the water softener.
How does a water softener work?
Put simply, hard water enters the water softener through the main water pipes. The hard water flows into the water softener and into a mineral tank containing resin beads. The resin beads collect the minerals and substitute them with sodium ions that soften water. Captured minerals cling to the beads, leaving soft water to flow into the plumbing system. Salt is then used in a brine solution to clean the beads of the mineral and regenerate, flushing the minerals down the drain.
Which types of salt are sold for application in a water softener?
You can only use salt designed for water softeners. These come in crystals, blocks or pellets. The type of water softener will determine the type of salt that is to be used.
How often should one add salt to a softener?
Because newer water softener models are more efficient with salt use, typically you only will need to add salt every 6-8 weeks. It is a good idea to check the salt tank regularly to make sure that it is full.
