Reverse osmosis (RO) produces clean, great-tasting water, and is widely regarded as one of the most efficient water filtration techniques. Numerous uses for RO systems exist, such as aquarium, whole-house, restaurant, among other sectors, which require water filtration. Whatever the initial quality of your water, there is probably RO system that will work for you. The definition of reverse osmosis, and the working of reverse osmosis systems for commercial sector, is described here.
When pressure pushes water through a semi-permeable membrane, reverse osmosis eliminates pollutants from unfiltered water, or feed water. To produce clean drinking water, water flows from the more concentrated side of the RO membrane to the less concentrated side. As a result, the permeate and the concentrate water is produced.
What is the process of reverse osmosis?
Before forcing water through a semipermeable membrane to remove dissolved solids, a reverse osmosis system filters out sediment and chlorine with a pre-filter. Before entering an outflow device or a faucet, drinking water is polished by a post-filter, after leaving the RO membrane. Depending on how many pre-filters and post-filters are used, reverse osmosis systems go through different stages.
Components of Commercial reverse osmosis system
A reverse osmosis system's main component is the RO membrane, but it also has additional filters. There are 3, 4, or 5 filtration stages in a RO system.In addition to the RO membrane, every reverse osmosis water system also includes a sediment filter, and a carbon filter. Depending on whether the filters are used before or after the membrane, the filters are referred to as pre-filters or post-filters.
Reverse Osmosis Filters
There are one or more of the following filters in each type of system:
1: A sediment filter which reduces impurities including rust, dust, and grim.
2: A carbon Filter which reduces chlorine, volatile organic compounds (VOCs), and other pollutants that cause water an unpleasant taste, or odour.
3: A semi-permeable membrane which removes up to 98% of the total dissolved solids.
What is Working of Reverse Osmosis Systems for Commercial Sector?
Step 1:Pre-filtration occurs before the water enters a RO system. To remove sediment and chlorine that could clog or harm the RO membrane, pre-filtration frequently entails the use of a carbon filter and a sediment filter.
Step 2:After that, dissolved particles, even those that are too minute to be detected with an electron microscope, pass through the reverse osmosis membrane, and are eliminated from the water.
Step 3:Water flows to the storage tank after filtering, where it is kept until needed. The reverse osmosis system stops filtering water, after the storage tank is full.
Step 4:When you turn on the water faucet, water flows from the storage tank via a second post-filter, to be polished before it reaches the faucet.
Why is a Commercial RO storage tank necessary?
Reverse osmosis water is kept in a RO storage tank, so you always have access to it when you need it. Reverse osmosis systems produce water gradually. Two to three ounces of RO water are produced in a minute. At the actual membrane production rate, you would need to wait at least five minutes for your faucet to fill up, if you wanted a glass of water. Your glass fills up right away, if you have a storage tank.
How durable are Commercial RO Plants?
These typically last 10 to 15 years. The RO membrane and filters need to be replaced from time to time, even if the systems themselves have a lengthy lifespan. Every six months to a year, the pre-filters and post-filters should be changed. The RO membrane needs to be changed every 2-4 years, depending on your water's quality.
