Reverse osmosis systems deliver pure and safe water. They remove over 99% of dissolved minerals and contaminants, down to particles that are even smaller than the wallet molecules themselves. In fact, most bottled water companies use reverse osmosis due to its reliability and safety. And with a reverse osmosis system of your own, you can produce pure and safe water at a fraction of the cost of bottled water.

What Are The Different Types Of Reverse Osmosis Systems?
Home reverse osmosis systems are typically installed under the sink, home reverse osmosis systems provide the purest and most affordable drinking water possible directly to the faucet
Aquarium reverse osmosis systems commonly include an additional deionization step that removes the remaining fraction of a percent of ions the may be small enough to pass through the reverse osmosis membrane, producing true zero ppm water.
Light industrial and commercial reverse osmosis systems are used in a variety of manufacturing applications – and they are perfect for restaurants. Light industrial RO systems are easy to use and save money on water.
Whole house reverse osmosis systems work as described: they produce pure reverse osmosis water for the entire house. They are ideal in situations where decent quality water may not be readily available or when pure, uncontaminated water is needed – such as skin sensitivities or special fabric applications. And they save pipes, too.
Desalination plants use reverse osmosis on a large scale to remove salt and other contaminants for entire cities. We don’t sell desalination plants 😉
How do reverse osmosis systems work?
Reverse osmosis systems use water pressure to force water through a semipermeable membrane known as a reverse osmosis membrane. This membrane which is no thicker than cellophane allows the water to permeate through, but stops other contaminants.
The process is called “reverse” osmosis because the water is forced through the membrane in the direction opposite to that which it would naturally flow.
What contaminants do reverse osmosis systems remove from water?
Reverse osmosis systems remove virtually all contaminants from water, including chlorine, pesticides, fertilizers, and even radioactive particles. The following contaminant chart details many contaminants that reverse osmosis systems remove. Reverse osmosis systems are also effective at removing virtually any other contaminants that may not be listed below.
What is GPD and how does it relate to a reverse osmosis system?
GPD stands for gallons per day. It refers to the capacity of your reverse osmosis system to produce water. People often consider upgrading to a higher capacity membrane, for instance from a 100 GPD to a 200 GPD membrane, not necessarily because they use that much water per day but because a higher capacity system produces water more quickly. This means the water will be available even during times during of heavy use.
Do reverse osmosis systems require any sort of ongoing monitoring?
Reverse osmosis systems should be checked regularly using a TDS meter so that you know when the time has come to change the pre and post filters (and DI if your system uses it) and also the RO membrane. This will help guarantee the water that you are drinking, bathing in or adding to your aquarium tank is always as pure as possible.
Checking your water with the TDS meter is a very simple process – but for those who desire ultimate convenience, in-line digital TDS meters are available that install permanently to your system and display the total dissolved solids at the touch of a button.
What is reverse osmosis installation like?
Reverse Osmosis Systems are generally simple to install. Among their requirements are a hole in the sink to allow for the dedicated faucet, having access to the kitchen area sink plumbing (typically located beneath the sink) and also a space for the compact storage tank. If room beneath the kitchen sink is restricted, there is the alternative to keep your Reverse Osmosis Water System set up in the basement.
What is the deal with the membranes that are used within reverse osmosis systems?
The RO membrane is the key component of the reverse osmosis system. The most widely used membrane is spiral wound. They can be of two varieties; cellulose tri-acetate (CTA) and thin film material/composite (TFM/C).
“Membrane flux” refers to the volume of water which can be transferred through a sq . ft . of membrane, and is measured in GFD (gallons per square foot per day).
Membrane choice is an additional critical area of concern. Various membranes have different rejection rates. Commonly, the top rejection rates are linked to the greatest required operational pressures.
The membrane system is made up of pressure vessel that has a membrane which allows feedwater to become forced against it. The membrane has to be sufficiently strong enough to handle whatever pressure is put on it.
In order to ensure optimal operation, membrane maintenance and cleaning must be conducted regularly.
Where are reverse osmosis systems commonly used?
Reverse osmosis systems are employed in a range of scenarios which include: drinking water water, aquarium water, humidification, biomedical uses and lab uses, dialysis, pharmaceutical drug manufacturing, beauty products, and even hockey ice rinks. In short, pretty well anywhere that pure water is required, a reverse osmosis system is among the best choices.
How did reverse osmosis systems originate?
Reverse osmosis systems were developed for use on Navy ships in order to desalinate salt water into pure drinking water. Today’s methods and advanced membranes last much longer than the original Navy membranes, and work more efficiently.
Is the water produced by reverse osmosis systems the best drinking water possible?
Drinking water produced by reverse osmosis system is guaranteed to be pure and safe. However, it doesn’t contain any of the beneficial minerals that may be found in water – they’re filtered along with other contaminants. That said, our bodies don’t miss these minerals – we get our minerals from our food, not our drinking water!
Nonetheless, a perfect mineral blend can provide perfect tasting water. For this, we sell and recommend remineralizers that will turn your perfectly safe and pure water into perfect water.
What are the stages and components of a reverse osmosis system?
While reverse osmosis systems vary, most of them include the following key stages and components:
1. An intake line and valve. This attaches to the cold water line and supplies water for the reverse osmosis system, which enters via the pre-filter.
2. A series of pre-filters. Prefilters are used to remove larger particles that don’t require your reverse osmosis membrane – and in fact, can damage or block it. A series of filters in descending sizes is commonly used prior to the reverse osmosis membrane. These may include sediment filters, granular activated carbon filters, coconut carbon block filters, or others.
3. A reverse osmosis membrane. The critical step that gives a reverse osmosis system its name, the reverse osmosis membrane filters the remaining microscopic particles left by the prefilters, leaving pure water.
4. One or more post filters. Most commonly carbon, post filters ensure that any remaining taste or odors are entirely removed, and provide a tiny amount of minerals in the form of charcoal that gives the water a more pleasing taste.
5. An automatic shut off valve. When the storage tank is full, the reverse osmosis system automatically stops producing water. When water is drawn from the tank again, the valve opens, and the system tops its tank up automatically.
6. A check valve which prevents any backward flow of water from the storage tank – which would both reduce pure water production and potentially damage the membrane.
7. A flow restrictor which provides optimal flow for pure water production, and helps maintain the pressure necessary to force the water through the reverse osmosis membrane.
8. A reverse osmosis storage tank which holds the pure water under pressure, so that it can be drawn from the reverse osmosis systems faucet.
9. A faucet. Reverse osmosis systems use their own faucets which are typically installed through an additional hole on the kitchen sink, with system itself underneath.
10. A drain line. This runs from the outlet of the reverse osmosis membrane down to the drain. It is used for disposal of the contaminants and impurities that have been removed by the membrane.
