What is Reverse Osmosis?


Reverse Osmosis (RO) is a water purification technology that removes ions, molecules and larger particles from drinking water through the use of a semipermeable membrane. The pressure from your water connection forces water through the semipermeable membrane and into the system. Common impurities removed by reverse osmosis filters include: fluoride, lead, pesticides, nitrates and sulfates, chlorine and chloramine and even detergents. Any contaminants that are unable to pass through the membrane are either returned to the drain or can be stored in the system itself and recycled once more. Permeate, also referred to as product water, is the water that successfully purified and stored by the reverse osmosis system. The permeate water the machines produce boast around 95-99 percent of salts and larger particles removed.

The majority of reverse osmosis machines contain four or more stages through which tap water can be sent through for optimum purification. While these filtered stages account for nearly half of all the components comprising a reverse osmosis water filtration system, there are usually 10 parts working in unison. These parts are: a cold-water line valve, pre-filters, a reverse osmosis membrane, post filters, an automatic shut off valve, a check valve, a flow restrictor, a storage tank, a faucet and a drain line. While this may seem intricate, reverse osmosis filters are regarded for their simplicity of maintenance as they possess few moving parts that can be easily replaced. By undergoing this process, the quality and appearance of reverse osmosis drinking water increases by improving in taste and minimizing odors. This, in turn, makes it a safe option for producing superior water for your home or business.

Reverse Osmosis Machine Options

Generally speaking, reverse osmosis filters are categorized for either residential or commercial purposes. Before you make a commitment to a specific reverse osmosis water filtration system, you should examine that capacity to which you will be utilizing the system.

  • First, check the number of stages/filters the system you are interested in houses. There should be at least one pre-filter and one post filter provided, but the more provided, the better.
  • Second, examine the capacity at which you would be using the reverse osmosis machine. In other words, determine how much water you will use, measured in gallons-per-day, and choose a reverse osmosis system that satisfies these requirements.
  • Lastly, before you purchase any product, examine the quality of the parts that are used. While reverse osmosis filters are simple in design and maintenance, choosing a product made from superior parts will help avoid unwarranted complications.

The same four questions raised above should also be considered when investigating the most viable whole house reverse osmosis system for your needs. Purified reverse osmosis drinking water can benefit your household and its inhabitants in a multitude of ways. While public water suppliers work diligently to provide clean water for their customers, contaminants that can cause issues in odor and taste are not regulated by the EPA. By installing a reverse osmosis water filtration system in your home, your quality of water will excel in taste and improve your health from avoiding contaminants. Having purified water can also benefit your appliances. Items like washing machines, dishwashers and faucets that depend on unfiltered public water can be inhibited by the contaminants it contains. Purified reverse osmosis drinking water can increase your appliance’s functionality and overall longevity by excluding these contaminants that can cause mineral build-ups, odors and films.

Industrial Reverse Osmosis Filters

It is also worth noting that you should familiarize yourself with the space available for the reverse osmosis machine of your choosing. Because reverse osmosis filters for businesses must work at greater capacity, the amount of space they occupy increases. Generally, you want a product that maximizes output while minimalizing the floor space it requires. To counteract this, look for reverse osmosis units that can be installed horizontally. Commercial reverse osmosis filters can also be retrofitted with additional benefits like programmable logic controllers, among other devices that simplify obtaining reverse osmosis drinking water readings. Our experts at Flag City Water will happily guide you toward the correct reverse osmosis water filtration system that meets even your greatest need.
