Reverse Osmosis: How Many Stages?

Reverse Osmosis: How Many Stages?

Reverse Osmosis

I often get asked by friends and customers alike,

“how many stages do I need in my Reverse Osmosis (RO) system?”

It’s a great question that often gets Reverse Osmosis talked about and as there are more and more systems available with 5+ stages it’s important to understand what the different stages do and whether or not they are a good investment.

In order to best understand this it is a good idea to Reverse Osmosis quickly understand what a basic RO system is and how it works.

The most basic Reverse Osmosis only require 2 stages.The first stage, a carbon block does two things. It filters down to a certain micron rating (a micron is a measurement of size, if someone is talking about filtering down to a certain micron level, they are referring to how small a particle would have to be to pass through the filter) and it also removes chemicals through chemical reaction (chemicals in the water bond onto the carbon block and get stuck there). In an RO system this would be referred to as ‘pre-filtration’ as it occurs before the RO membrane.

The second stage,

the RO membrane itself is a thin film of composite material that filters at a molecular level rejecting the majority of contaminants in the water by size or electrical charge. The holes or ‘pores’ in the film are so fine that water will only flow through under pressure, the more pressure the faster the water can flow through. Since tap water pressure is not that high, the flow rate of the pure water through an RO membrane is quite slow and would take a couple of minutes to fill one glass. To combat Reverse Osmosis this, reverse osmosis systems have the capability to operate at much higher pressure levels than tap water pressure. Parsing is an essential part of RO system for getting authentic mixed mineral water.

Another advantage of having a RO system is that it can be set up to make clean drinking water source that is completely safe and economical on entire house basis.asers and filters are not required to be part of the part of the system for tap water; however, as they are for tap water, they need to be installed as part of the RO system. This can be done easily using screws, nuts, and bolts. screws and nuts act as anchoring devices to keep the filters and enzancer from colliding with each other. One benefit of having the filters installed as a system is that the arsenic and lead levels in the water Reverse Osmosis can be reduced substantially.

When the filters have been installed and the appropriate test results obtained, the next step is to replace the dirty or ‘filtered’ water with clean drinking water. Safe drinking Reverse Osmosis water is highly recommended by health units for many reasons. While at first glance it may seem to be a daunting task, health units recommend that, when one has the opportunity to drink from clean water, one should take the easy steps necessary to protect one’s health. Poor water purification methods can lead to serious health problems.

Although a purifier cannot make water Reverse Osmosis taste any better or make it smell any better than tap water, it does reduce the amount of harm it can do to you. The installed filters can reduce the threat of contaminated water getting into your home from storm drains, wells, and manure stored up on the farm or in the city. It can also reduce the odor and taste of city water, which can often beolesolive odor. An important feature to the water purifier is that it must be certified to reduce lead from drinking water.

If you want clean fresh drinking water, aside from purchasing a water purification system, you can also install a number of device in your kitchen and other locations that will make it easy to obtain clean, pure, and contaminant free water.
