REVERSE OSMOSIS SYSTEMS
With the increasing lack of water purity becoming a bigger issue every day, concerns about drinking water have reached epic proportions. The increase of First World industrialization, combined with the pressing need to improve potable water in Third World countries, has prompted science to work diligently to develop purification systems to remove harmful contaminants.
One of the most popular means of water purification is reverse osmosis. Reverse Osmosis (also known as RO), is a method of removing large particles from drinking water. RO works by filtering water through a membrane. The membrane contains holes called pores that allow the purest part of water through, while trapping the larger molecules in a separate side. The trapped molecules can be anything from bacteria, salt, fluoride, and other contaminants.
Reverse osmosis is part of a process called hyperfiltration. Hyperfiltration works by decreasing particles to the molecular level. This process leads to the development of clean water. Reverse osmosis filters removes salts and other water pollutants, which produces pure water.
This is the general process by which reverse osmosis works. The performance of ROs varies depending on a number of variables. These variables include water pressure, the kind of filters and membranes used in the RO, water temperature, and the presence and/or level of total dissolved solids (TDS).
RO systems operate as tap water passes through a membrane and filter. This can be a single process or a series of membranes and filters. The membrane allows only water to pass through, but contaminants and impurities are left behind and emptied. Then, pure water travels to a holding tank that is accessible to a faucet.
Which RO System is Best?
Determining the best RO system to purchase for home use is dependent on several factors. These factors will vary from person to person and family to family.
Before the days of Consumer Reports and websites like Amazon that provide customer reviews, it was very difficult to determine the true value of a product. Companies spend billions of dollars on advertising and marketing campaigns to convince consumers that their product is the best and the most desirable of its kind on the market.
However, in 2015, an informed consumer can conduct research using the internet, using it to read product reviews, Consumer Reports and other unbiased rating organizations. This research can help buyers determine the difference between a product that promises great results and one that delivers those results.
Of course, the quality of an RO system is subjective. While everyone will agree that a 5-star or 4-star review is more impressive than a 3-star or less review, the needs of consumers are different. While one buyer of an RO system might be concerned about lead in their water, another may be more concerned about sodium or fluoride.
An informed RO consumer needs to review what contaminants a system specializes in removing and find a products that services their particular needs.
As always, the cost of an item will be a considerable factor in purchasing an RO system. Prices of the more reputable systems range from $140 to $300.
When it comes to something as important as protecting the water you drink, you might be willing to pay a lot more than you would for other purchases. But budgets and financial considerations may still come into play. Therefore,
- Decide in advance what you can afford
- Make a list of systems that fall within your budget
- Narrow the list of remaining systems based on your needs and preferences
Type of System
There are a variety of RO systems available on the market. Some attach directly to faucets. Others attach under sinks and counters, while still others are countertop models.
The best system for you may depend on several factors:
- Your living quarters – your preferred system may vary based on whether you live in a house or apartment.
- The area you live in – the city or state you live in may determine the type or level of contaminants in the area, and will influence what system you will need
- The level of quality you desire in an RO system
- The price of the RO system
Other Deciding Factors
When choosing an RO unit, ask yourself the following questions:
- How many filtration stages do I need?
- How many gallons per day (GPD) of clean water do I need?
- Is the type of membrane important for my needs?
- What do contaminants do I want to remove from my water?
- Does my tap water contain chlorine?
RO units feature several stages of filtration and contaminant removal, generally between 2 and 4.
- 2-stage RO units – These units are light and compact, easy to store, and move around. They contain a pre-filter and the membrane. These systems are good when you are dealing with a lack of space. 2-stage units are more affordable than other RO systems.
- 3-stage RO units – Larger units that use carbon or sediment pre-filters in addition to the membranes. These units are higher in quality than 2-stage units, they are designed for everyday use, and are more durable than the 2-step units.
- 4-stage RO units – These units include the deionization process. The deionization unit removes any contaminants that have not already been removed. This process filters to 99% or even greater, providing the maximum amount of decontamination.
Benefits and Drawbacks of RO Systems
As with anything in life, there are pluses and minuses to using RO systems. Here’s a brief overview
Benefits of RO Systems
- They provide pure drinking water by desalination and the removal of dangerous contaminants
- The improvement or removal of odors and bad tastes
- They requires little maintenance, which mostly consists of replacing water filters
- They are easy to use, providing clean drinking water without much effort or trouble
- Depending the cost and effectiveness, they provide an affordable way to achieve clean drinking water
Drawbacks of RO Systems
- Some RO systems are not able to get rid of dangerous chemicals like chlorine, pesticides and herbicides. This is because these contaminants have molecules that are smaller than water. The only RO systems that are capable of removing these dangerous contaminants are systems that are equipped with carbon filters.
- Even the best RO systems are wasteful of clean drinking water. Most Reverse Osmosis systems waste 2-3 gallons of water for every gallon of clean drinking water that is produced.
Final RO Advice
RO systems need regular maintenance to operate effectively. Read and follow the instructions in the operating manual that comes with your RO system to make sure that you are operating the system properly and you are following the manufacturer’s instructions. You should always replace filter cartridges, membranes and other items as instructed by the manufacturer’s specifications.
While considering the quality of the RO’s filter system, it is crucial to investigate the manufacturer to determine their ability to supply future equipment. The importance of purchasing a reliable RO system, and the desire to keep it in good working order for many years means that the manufacturer must provide excellent support and part replacement. Technical support and customer service are a must for major purchases. Another important factor to consider is the number of satisfied customer reviews for RO systems. Obviously, the four and five star reviewed systems are to be preferred over other lesser rated systems.
One of the reasons it is prudent to investigate manufacturers and suppliers is because some of them make promises that they cannot keep. One warning sign is the offer of long warranties of 5 to 10 years. The danger of purchasing a system with long warranties is that they are often referred to as conditional. This means that proof of maintenance will need to be provided for the system to be covered under the warranty, and the warranty may or may not cover your particular problem or parts. Be careful and read the warranty very carefully.
Many factors go into the successful purchase of a Reverse Osmosis system. Research carefully, compare thoroughly, and buy according to what you can afford and what system is best for you.
