What is Reverse Osmosis?

Reverse Osmosis refers to water that has undergone filtration using a specialized membrane system. This process, reverse osmosis filtration (RO), is dependable for ensuring access to cleaner, safer, and better-tasting filtered water whenever needed.

Delve into the details to gain insights into reverse osmosis water purifiers and its potential benefits for your home.

Reverse Osmosis - Definition

As the name suggests, RO reverses the osmosis process. RO is a water filtration method capable of reducing up to 99% of certain contaminants in water, encompassing both visible and microscopic particles. This generally involves a multistage procedure where water is forced through a specialized semipermeable membrane and other filter types. The outcome is purified water suitable for drinking, cooking, and other routine purposes.

How do Reverse Osmosis Systems Differ from Other Water Filters?

While often referred to as "RO filtration," it is crucial to understand the distinction between reverse osmosis and conventional water filtration. Reverse osmosis is not simply a filter; it is a distinct process. The RO membrane facilitates this process, but technically, it does not qualify as a filter either. When people mention reverse osmosis filtration  they typically encompass the entire multistage process inherent in most RO system. It is essential to note that reverse osmosis represents just one phase within this comprehensive process.

Comparisons become more nuanced when evaluating RO systems in contrast to other types of water filters. Basic systems utilize activated carbon, with some incorporating additional filter media. While carbon filtration effectively mitigates chlorine's taste or odor in drinking water and addresses specific aesthetic water concerns, its efficacy may be limited in reducing dissolved solids, arsenic, viruses, and bacteria. In contrast, RO systems are one of the most efficient methods for treating water across a spectrum of potential contaminants.

Type of Contaminants Removed Through Reverse Osmosis:

An efficient RO water purifier can decrease a variety of contaminants in drinking water, contributing to the manifold advantages of possessing a reverse osmosis filtration system. Here are a handful of instances of water quality concerns that an RO system might assist in managing:

RO Can Remove Lead from Water:

Lead in drinking water can come from homes with lead service lines that connect the home to the main water line. Minimize or eliminate your contact with lead in tap water by consuming or utilizing only tap water that has undergone filtration through water purifiers. Reverse osmosis (RO) systems effectively eliminate lead from water. Given the rising concern about elevated lead levels in India, the importance of removing lead from drinking water cannot be overstated. 

RO Can Remove Pesticides from Water:

Reverse osmosis filter systems can eliminate pesticides, herbicides, and from drinking water. The carbon block filters within the RO system play a crucial role in trapping these harmful chemicals. 

RO Can Remove Chlorine from Water:

Specific individuals find the taste of their tap water unappealing. This can be attributed to disinfectants such as chlorine, employed to ensure water safety from germs, or the influence of minerals and naturally occurring contaminants like sulfur-containing compounds that, while not harmful, can alter the water's taste. Activated carbon filters prove effective in mitigating undesirable flavors and odors. Additionally, reverse osmosis systems contribute to taste improvement and chlorine level reduction.

RO can remove heavy metals like Cadmium and Chromium

Reverse osmosis filters excel in eliminating heavy metals owing to their highly effective filtration mechanism. The minute pores of the membrane adeptly capture even the tiniest particles, guaranteeing the efficient removal of heavy metals from the water supply. To mitigate exposure to lead in tap water, opt for drinking water purified by certified RO membranes.
