10 Things to consider when buying a residential reverse osmosis system

 

Buying a new water purifier or reverse osmosis system for your home can be simplified if you get in prepared with the necessary knowledge. Before buying a new unit consider this:

1.Any RO system should comprise of at least three pre-filter stages – one sediment pre-filter rated at 5 microns, and two granular activated carbon filters. The granular activated carbon filters should ideally be catalytic carbon to remove chloramines.

filters three stage

2. The pre-filters are an important part of your Reverse Osmosis Filter, the sediment filter protects the carbon filters, and the carbon filters protect the reverse osmosis membrane, which is prone to oxidation damage from chlorine or chloramine.  Chloramines are a combination of ammonia with chlorine. Unlike straight chlorine, which dissipates fairly quickly when exposed to air, chloramines remain in the water. Chloramines are very difficult to remove from your water supply.Chloramine_Diagram

 

3.Ensure that your RO membrane is from a reputable company like DOW TFC membranes, and should be at least 50 GPD( gallons per day).

4.Be wary of any salesman that tells you that they have a pure water to waste water ratio of 1:1 . The ratio is more likely going to be 1:3 or 1:5 (pure:waste) . This ratio is necessary to ensure continuous high performance of your RO membrane, and helps flush contaminants from the tiny pores(0,0001 microns) which otherwise can get clogged.  This ratio is also dependent on a number of factors including water quality.  High dissolved solid content like for instance hard water, will require a higher flush rate. A  flow restrictor by-pass is also recommended as that will help clean out the membrane surface by initiating a high flow.

comparative sizing

5.Residential RO membranes can only be used for town water supply i.e. chlorinated water with relatively low dissolved solid content. They should not be used for river, dam or rain water.  Special membranes are required for brackish and seawater and they require significantly different configurations to suit the increased osmotic pressure caused by the increased salinity.  Seawater which has a salt content of above 35,000 ppm would require at least 24 Bar just to overcome the osmotic pressure. Residential RO systems should be operated at pressures of 300 to 800 kPa( 3-8 Bar)- low water pressure means you would require a booster pump with your RO system, which is normally just a add-on.

6.The purified water from your reverse osmosis system is slightly acidic as the water is devoid of any minerals and the remaining CO2 gas in the water causes the slight acidic conditions. Hence we recommend a mineral or alkaline stage that does two things; it provides minerals back into the water (Calcium, Magnesium, etc) and also increases the ph to levels above 8. The added minerals will also help provide buffering capacity to the water.

PH-Scale

7.Reverse osmosis systems are the best purifier to remove fluoride from water. The level of fluoride added is typically 0.5 ppm .  Activated carbon does not remove fluoride, activated alumina and ion exchange resins with fluoride specific ions can, but require significant contact time.  They also become saturated and to find out when that happens can be rather expensive. Measuring residual fluoride in water in the parts per billion range is very expensive- and the filter sales people know that. It is therefore better to rely on reverse osmosis filters, as the method of removal is by size exclusion. The size of the fluoride ion is larger than the tiny pores of a membrane which are only 0.0001 microns.

8.There are three options for RO systems ; Tank option ,direct flow option and also units that automatically fill up a portable reservoir . A buffer tank with a bladder provides adequate flow when you want to fill up a glass.  Ensure the tank is manufactured from food grade approved materials.  Direct flow units are also popular but to be practical should produce at least 400 GPD of purified water.  Automatic RO systems like the Astroboy, are becoming very popular as they allow the portable container to be taken anywhere, or positioned into a water dispenser.

ASTROBOY

9.A final stage carbon polishing filter is also recommended to ensure there is no residual taint as a result of water sitting in the line or the storage tank

10.Quick change cartridges are becoming very popular, as they require very little effort to replace and no tools.  Remember be very diligent about changing cartridges- as that will ultimately ensure consistent good quality water and ensure your reverse osmosis membrane will last at least 3 years.

Benefits of Alkaline Water Filters

Alkaline Water Filters  and it’s Health Benefits

 

You probably have heard about the benefits of minerals in alkaline water and the benefits of  alkaline water .  However,  you don’t have to look too far to read about  negative publicity relating to  alkaline water . 

The negative  publicity  claims that your stomach fluids are acidic and you need the acidity to digest the food.  Others argue, that the amount of minerals in water can hardly make an impact  on the overall pH of your body.   The reality is that detractors of alkaline water often have a limited understanding of chemistry and the physiology of the human body.   Whether the stomach content is acidic, does not change the fact that the pH balance of most of the body is alkaline. The pH of blood for instance when in the healthy range should be between 7.35 and 7.45.  There is plenty of research showing the link between acidic pH and cancer. Cancer thrives in an acidic environment and cannot survive in an alkaline environment. Cancer cells make your body even more acidic as they produce lactic acid. So if you have cancer, your pH levels are low and your body is too acidic – See more at cancer fighting strategies. 

alkaline water ph scale

A lot of food we eat today is acidic and that includes grains, dairy products, fish, and meats like bacon  and turkey. All in all, the alkaline diet is a healthy alternative. Eating more fruits and vegetables, along with curbing your carb and dairy intake, may help balance pH levels within your body. Once it’s in a stable state, this can reduce daily complications and lower the possibility of greater, long-term risks. 

There is no doubt that water can play a vital role in helping maintain a stable  body pH.   Alkaline water in particular containing minerals and elevated pH will help in maintaining stable pH levels in your body.  the minerals are essential for your health and provide buffering capacity to neutralise acids.  Water may appear to be a simple molecule ( H20)- but we are yet to learn all about the different forms of water  and the secrets of the Hydronium Ion.

Be amazed by the amazing properties of water – facts that most people don’t know.

There are a range of alkaline water filters on the market and the alkaline filter cartridges  can be retrofitted to most  Reverse Osmosis Filters.  These alkaline water filter cartridges  come in all shapes and sizes and  usually are connected up with simple but reliable push-in fittings. Some examples are listed below:

KClean Alkaline Cartridge:

Includes far-infrared ceramic balls incl Tourmaline, Mai -Fan Ceramic Stone

Far-Infrared ceramic balls incl Tourmaline:

Tourmaline gemstone is a semi-precious mineral stone well known for its incredible ability to aid in the detoxification process of the human body. It is one of only a handful of minerals that have the ability to emit negative ions and far-infrared rays. Tourmaline is best known as one of the only minerals to naturally emit far infrared heat and ionisation. Tourmaline exerts a cleansing energy on our nervous system. 

tourmaline ceramic ball

 

Mai-Fan Ceramic Stone: 

This rare natural mineral stone, combines with water to generate indispensable minerals for the body, such as Calcium, Iron, Silicon, Magnesium and Aluninium, at the same time, revitalising the water, emiting FIR (far-infrared rays) to produce `living water’.

The Mai-Fan Stone also adjusts the pH value and by the process of Ion Exchange neturalises the acids and turns the water into  alkaline water. 

 Maifanshi water has powerful antioxidant properties, many times superior to the presently known antioxidants (vitamins C, E, carotenoids, etc.).  

The filter also produces Hydrogen rich water. “Hydrogen-Rich Water” or hydrogenated water contains active hydrogen ions that act as powerful antioxidants in your body. The ions help eliminate oxygen free radicals that contribute to the development of illness and ultimately are responsible for the aging process.  Our body takes in the H2 and converts it into hydrogen anions, H-. or commonly termed as active hydrogen. Active Hydrogen is a powerful anti-oxidant as it is able to remove the active oxygen in our body that is known to be the cause of many types of chronic diseases. Molecular hydrogen also has anti-inflammatory effect besides its antioxidant properties. Inflammation is a silent killer that caused many chronic diseases. Hydrogen has also been found to have an anti-tumor effect.

 

The KClean Alkaline Cartridge produces potent  hydrogen rich antioxidant water and has been proven in laboratories to produce alkaline water and reduced chemical contamination.

Purepro Alkaline Cartridge

The Alkaline filter changes the acidic RO water into a perfect Natural Alkaline Ion Water. The PurePro® Alkaline filter simply gives back minerals such as ionised calcium, magnesium, sodium, potassium ion, which were removed by the reverse osmosis process.It produces alkaline water which helps your body maintain a healthy pH level. The PurePro® Alkaline mineral filter is very  effective and  produces a  pH value of 8.00~9.50( depends on contact time)

 

  •    Produces perfectly pH-balanced alkaline water, helps minimise the fluctuations of your body’s pH.

  •    Converts  acidic drinking water into alkali calcium ionised water. 

  •    The natural calcium, magnesium, sodium, potassium ions can be fully absorbed   by the body.

  •    It is easily absorbed in the body because it has structurally smaller molecules which help the body absorb  more water and hydrate more rapidly.

  •    This filter improves the qualities of clean water by adding minerals necessary for proper human development and health minerals, such as Calcium, Magnesium, Sodium, Potassium and others readily found in many natural mineral waters.

And… Just a final word from an article in an on-line forum ” Smoke and Mirrors”  to the detractors of Traditional  Chinese Medicine:

Joey Says:

  1. Why do so many people think just because something is not understood that it is false. I am an mechanical engineer and business man. In my profession almost every experiment performed has some level of uncertainly and gives minor to major unexpected results. This is due to limited information and incomplete understanding of what we are working with.
    I think your drawing conclusions on your false assurance of your complete and total understanding of the world. Have you noticed even though modern medicine(only <100 years old profession) and doctors (before modern times only known as monks, shaman, and witch doctors) are now the undeniable and undisputed experts on nature and the human body. At least engineering has a good 2000 years of practice.
    Open your eyes. In the past 50 years, with all the advances in modern science, some how the human race is noticeably less healthy compared with earlier times. In old times, the most common cause of death were pneumonia and other infections. Now we have obesity, heart desease, stress related items. We are a mess as a race. Part of it is the pharmaceutical companies and their invention of ‘drugs’ that serve one purpose but cause major side effects which many attribute our continuous health problems to.
    The only medicians that can be ‘possibly’ proven worth taken are those with hundreds of years of use. Mainly oreintal remedies. ALL oil based pharmaceutical company drugs are not proven. No old and natural remedy will ever be accepted by the FDA. It cost on average $800million US dollars to get a DRUG through the FDA and approved. Noone other than a huge pharmaceutical company has the ability to finance this. One final point. Big Business is only interested in the bottom line(profit) for its stock holders. Do you want to put your life in the hands of these groups. Please, do not hand out these assumptions about possible remedies unless you have proof to the unsafeness or ineffectiveness. Every commercial you watch on TV about drugs is just brainwashing you to think they are safe and affective(repetition of an idea will eventually lend to the acceptance of that idea). Try to be a truth leader not a sheep follower.

Alkaline Water Filters and Alkaline RO Water Filters

 

Pacific Water Technology has launched a range of alkaline water purifiers and RO water filters into the Australian market.   Also known as alkalisers, these alkaline water filters remove unwanted contaminants from your water and replace with  a healthy balance of minerals . These systems all ensure a healthy balance of minerals are added to the purified water whilst also providing a higher pH and increased buffering capacity.  High pH  alone is not sufficient to deliver healthy alkaline water- for that you need minerals that provide the buffering capacity and neutralise acids- More- See Dr Sirkus. There is no doubt that water alone will not provide the  amount of minerals required  for good health- but can play a vital role. Some 21 mineral elements are known or suspected to be essential for humans.  At least  fourteen mineral elements are established as being essential for good health; these elements in combined form affect bone and membrane structure (Ca, P, Mg, F), water and electrolyte balance (Na, K, Cl), metabolic catalysis (Zn, Cu, Se, Mg, Mn, Mo), oxygen binding (Fe), and hormone functions (I, Cr).  More:  Nutrients in Drinking Water- World Health Organisation.

Health consequences of micronutrient deficiencies include increased morbidity, mortality due to reduced immune defense systems and impaired physical and mental development. Deficiencies of several mineral elements, particularly iron and iodine, are the basis of health problems in many parts of the world. Some minerals and their respective importance for health are listed below:

 • Calcium – important in bone health and possibly cardiovascular health

• Magnesium – important in bone and cardiovascular health – more: Magnesium online resource center

and Magnesium-Fact Sheet for Health Professionals

• Fluoride – effective in preventing dental caries

• Sodium – an important extracellular electrolyte, lost under conditions of excess sweat

• Copper – important in antioxidant function, iron utilisation and cardiovascular health

• Selenium – important in general antioxidant function and in the immune system

• Potassium is important for a variety of biochemical effects but it is usually not found in natural drinking waters at significant levels.

Listed below are some of Pacific Water’s range of alkaline water filters:

KCW 006 Alkaline Water Purifier.

Ultrafiltration with added alkaline stage provides healthy minerals to your water

Ultrafiltration with added alkaline stage provides healthy minerals to your water

The  KCW-006 alkaline ultrafiltration system comprises of 4 Stages of  filtration including ultrafiltration and anti-oxidant water purifier providing healthy anti-oxidant water  with a high mineral content. The activated carbon stage includes a Calgon catalytic carbon stage- one of few activated carbons available in the market that effectively remove chloramines.  Chloramines are commonly used for secondary water disinfection.

  • Low negative ORP (ORP:-200mv~ -500mv), giving it strong and measurable antioxidant potential, which has significant health benefits.
  •  Alkaline water(PH: 8.5~9.8), improves your systemic acid/alkaline balance, enhances your  immune system.
  • Includes Tourmaline:Tourmaline is  well known for its ability to aid in the detoxification process, and for balancing metabolic functions.When placed in water, slight pressure contributes to a piezoelectric effect that supports water’s crystalline structure.
  • Includes MAI-FAN CERAMIC STONE- This rare natural mineral stone, combines with water to generate indispensable minerals for the body, such as Calcium, Iron, Silicon, Magnesium and Aluminium, at the same time, revitalising the water, emitting FIR (far-infrared rays) to produce `living water’.

Water Ioniser with Nanofiltration

WATER IONISER JA-703

A membrane filtration system ( Nanofiltration) , that provides purified water to a water ioniser capable of producing four levels of  alkaline water and two levels of acidic water. The Nanofiltration allows monovalent ions to pass through  and ensure satisfactory conductivity for ionising the water.  Alkaline ionised Water is a powerful Antioxidant providing the body with tremendous amounts of hydrogen that gives you lots of Energy. Water Ionisers is one of the greatest preventative health advances and technological marvels of the 21st century. It is very Alkaline and helps neutralise and flush acid waste from the body.  It is a superior Hydrator and Detoxifier because Ionised Water molecule clusters have been “reduced” in size (from 10 to 5) and therefore is “lighter”. Alkaline Ionised Water’s smaller size allows it to hydrate your body more effectively,  flushing  out toxins as it easily passes through your body’s tissue.

 

Pacific Water Technology has opened a new warehouse and showroom where customers can view a number of reverse osmosis water filters that have been installed for the purpose of demonstration. We are located in Seventeen Mile Rocks. More:
