How do I get a free water test?
Please contact us, by phone on 2778 3282 or fax on 2778 3280, to book a free water test at your home, or office.
We will undertake a direct comparison of water quality between your tap water and some tap water treated by our Reverse Omsosis system. This will show you the volume of dissolved solids (TDS) in particles per million (ppm) as well as a broad spectrum of what those contaminants are. At the same time we can assess what system is applicable for your individual requirements.

What geographical areas does Life Solutions service?
Hong Kong, Macau, Southern China and Shanghai.
I was told that Reverse Osmosis (RO) units remove minerals. Is that true?
It’s true that RO units remove some minerals but that isn’t really the whole story. The mineral issue is probably the most controversial question in drinking water purification. “Experts” on both sides of the issue speak convincingly.
Minerals in water are inorganic and hard for your body to use. You get most of your minerals from food, which provides organic, easily assimilated minerals. The human body is a sophisticated instrument capable of adapting to a wide range of circumstances and capable of thriving in areas having water of high or low mineral content.
As long as water is palatable, it’s within the body’s acceptable range. However, your drinking water should contain minerals (unlike distilled which has none), otherwise nutrients in your body can be lost through your body’s waste disposal system. The main issue with water is chemicals, not minerals. Whether water contains 30 or 3 parts per million calcium isn’t really significant, but the difference between 0.5 and 5 parts per million chloroform is of life or death importance
How long will a Reverse Osmosis (RO) unit last?
Typical membrane life is about 3 to 5 years, depending on the nature of the water that it’s processing. Life Solutions Systems are guaranteed for life as long as they are serviced by us. Therefore we will replace membranes as frequently as is required.
Can you hook the Reverse Osmosis (RO) unit to my fridge/icemaker etc?
Yes, and to your coffee-maker, steamer and to any other appliance requiring potable water.
How does a TDS meter work?
TDS meters are, in reality, conductivity meters. They work by applying a voltage between two or more electrodes.
Positively charged ions (e.g., sodium, Na+; calcium, Ca++; magnesium, Mg++; hydrogen ion, H+; etc.) will move toward the negatively charged electrode, and negatively charged ions (e.g., chloride, Cl-; sulfate, SO4–; bicarbonate, HCO3-; etc.) will move toward the positively charged electrode.
Because these ions are charged and moving, they constitute an electrical current. The meter then monitors how much current is passing between the electrodes as a gauge of how many ions are in solution.
Are your membranes good quality?
In short the answer is yes they are top quality.
Our membranes are manufactured in the USA by DOW Chemicals (Filmtech membranes). They have an excellent rejection rate of between 92 â€“ 98% even our high capacity gallons per day membranes sustain that high rejection rate.
Can I remove the nitrates from our water when using a Reverse Osmosis (RO) unit?
Nitrate removal when using reverse osmosis membranes is about 90-95%. So if you currently have 10 ppm of nitrate, then your levels after treatment should be around 0.5 – 1ppm.
Is it necessary to change the pre-filters on my system every 4 months?
Yes and this will be scheduled and carried out by our technicians as part of our annual maintenance. Our systems have been designed to operate best to give high quality purified water with normal routine maintenance. By changing the pre-filters on a regular basis, you will eliminate dirt and chemicals in the water that will plug the membrane. After six months of use, the carbon filters can have bacteria growing within the filter media. Your local water conditions may necessitate more frequent filter changes.
Can the water be saved and used?
Most wastewater today is recycled for golf courses and artificial lakes. The drain water is slightly higher in TDS concentration than the incoming water, but as R.O. does not add anything to the water, it can be used to water gardens.
Is water wasted down the drain with RO systems?
There is a certain percentage of water from the system that goes to the drain. This water is carrying away the impurities that have been filtered out by the RO membrane.
What is meant by Total Dissolved Solids TDS?
In the natural cycle of water, water that began its life as rain and eventually found its way to your tap has come in contact with many sources of potential contaminant. The various minerals and salts that have been dissolved by the water during this cycle are called Total Dissolved Solids (TDS).
How often does the Reverse Osmosis (RO) membrane need to be replaced?
With proper maintenance of your sediment and activated carbon pre-filters, your reverse osmosis membrane should last 2-5 years.
Does Reverse Osmosis (RO) remove chlorine?
A reverse osmosis membrane will remove chlorine but will degrade when in contact, therefore a Carbon Block pre-filter is used to remove the chlorine first thus protecting the RO membrane. Pre-filters will be changed regularly by our Life Solutions technicians to prevent membrane fouling, as part of our annual maintenance.
Does Reverse Osmosis (RO) waste a lot of water?
It depends on what you mean by waste. A home RO unit uses water to clean itself and wash away impurities. It’s like a lot of other water-using appliances. We use water to wash clothes, to wash dishes, to wash cars, to flush toilets. A reverse osmosis unit uses more water in its operation than you actually consume., In terms of expense, it’s like a couple or three extra toilet flushes a day.
What is a booster pump?
A booster pump is used to increase inlet pressure to the Reverse Osmosis (RO) membrane. RO membranes require a minimum of about 35 PSI to operate however our technicians will test your water pressure and install a pump or regulator as required.
Why do I need a pre-filter system if the Reverse Osmosis (RO) Membrane takes out the contaminates anyway?
Reverse Osmosis (RO) membranes are designed to filter out contaminants at the molecular level. It is absolutely essential to remove water supply contaminants larger than 5 microns before passing it to the RO membrane to prevent fouling and clogging.
What are some of the disadvantages of RO?
The disadvantages are:-
– Process is relatively slow, requires a storage tank.
– Requires a connection to your drain for wastewater.
– Production can be adversely affected by low water pressure and low temperature.
What are some of the advantages of Reverse Osmosis (RO)?
The advantages are:
– Ultra fine filtration at the molecular level.
– Filters out 98% of all unwanted molecules.
– Membranes last typically 2-3 years.
– Cross flow process prevents membrane from clogging.
– Easy to maintain, requires only routine maintenance which is provided by Life Solutions as part of our annual maintenance.
– Large storage tank for water-on-demand.
What is Reverse Osmosis (RO)?
Reverse Osmosis (RO) is the most effective filtration technology available. The RO process works by separating contaminants from water by forcing the water through a semi-permeable membrane. This membrane acts as a physical barrier to almost all molecules with a molecular weight greater than 200 grams/mole.
For example, the membrane may allow passage of water molecules, but blocks molecules of dissolved salt or other harmful contaminants. Unwanted molecules are blocked and discarded by the membrane while the ultra-pure water continues on for use or further treatment.
This process takes any unwanted molecules retained by the membrane and sweeps them away to your drain. This filtration process prevents the membrane’s surface from clogging, thus allowing the filter to last long.
What are the advantages of RO?
1. Health: Reverse Osmosis (RO) removes harmful contaminants while retaining some good minerals, which is beneficial to health and makes water taste fresh.
2. Environmental Benefits: RO can reduce glass and plastic waste, because there is no need for plastic water bottles, the production of which creates air, water and soil pollution as well as uses non-renewable oil byproducts. What’s more, some high quality RO models are also more energy and water efficient than other water filter systems.
3. Cost Saving: Compared with bottled water for a whole office, RO systems usually save more money in the long term. Also, RO systems avoid and reduce administration time and labor costs.
4. Quality: Compared with the bottled water which has been stored for a long time, RO systems provide fresher, cleaner water. Life Solutions RO systems have largely been chosen because they effectively and efficiently filter dirty water, and they reliably provide safe, clean drinking water for our clients.
