Everything you need to know about Reverse Osmosis:
Reverse osmosis is a process to remove all contaminants from feed water by applying external pressure forces on a semipermeable membrane. In this process, the feed water flows from the high concentrated side of the RO membrane to the low concentrated side (fewer contaminants) through a semipermeable membrane to give fresh and clean drinking water. The concentrated water molecules left over is known as waste or brine.
A semipermeable membrane contains very small pores that can block all the contaminants and only allow water molecules to flow through it. In the osmosis process, less concentrated water moves towards high concentrated water through the membrane to maintain equilibrium on both sides. But the reverse osmosis process blocks all the highly concentrated contaminants from entering into the less concentrated side through the membrane. Suppose, for example, when pressure is applied to the volume of sugar water during this reverse osmosis, the sugar molecule is left on the high concentrated side, and clean water flows through the low concentrated side.
Working principle of Reverse osmosis:
RO process working principle is opposite to the osmosis process. Osmosis occurs naturally, but here in the RO process, we need to apply some external pressure on the high concentred contaminant side to pass water molecules into the low concentrated side to produce fresh and clean water.
What can a reverse osmosis system remove?
A reverse osmosis process can remove all dissolved solids like fluoride and arsenic through the RO membrane. It removes fluoride, salts, chlorine, pesticides and bad taste, odours, and dirt too.
Benefits of the reverse osmosis process:
- The following are the benefits of the reverse osmosis process:
- RO process removes all dissolved solids from water.
- This process also removes the bad tastes and odour of the water.
- It gives you clean and fresh water.
- You can easily install them and maintain them too.
The life span of reverse osmosis systems:
Reverse osmosis systems can at least last for 10 and 15 years. So absolutely, the system has a long lifespan; only the RO membrane and filters need to be replaced periodically. Both the pre filters and post-filters need to be changed every six months to 1 year. Depending on the water conditions, the RO membrane needs to be replaced every 2-4 years.
Applications of reverse osmosis:
The following are the reverse osmosis applications :
- Food and beverages,
- Pharmaceuticals industry
- Diary industries
- Coaching institutes
- Bus stands
The reverse osmosis process produces clean water and also gives you freshwater by removing harmful dissolved solids.
