What is a Reverse Osmosis System
What is a Reverse Osmosis System
A Reverse Osmosis (RO) system is a multi-stage water filtration system that uses a semipermeable membrane to remove most of the dissolved solids, chemicals, and impurities in your tap water. It forces water through the membrane under pressure, leaving contaminants behind. RO is known for producing exceptionally clean drinking water. It is widely used in homes for improved taste, safety, and purity.
Why should I choose an RO system over other filtration methods?
Why should I choose an RO system over other filtration methods?
RO systems remove up to 99% of harmful contaminants such as heavy metals, PFAS, nitrates, chlorine, fluoride, and micro-sediments commonly found in tap water, while carbon filters only remove taste and odor.
If you want truly purified drinking water, RO is the most effective household filtration technology.
How does an RO system work?
How does an RO system work?
A RO system typically filters water through several stages, including sediment, carbon blocks, and the RO membrane. The membrane allows water molecules to pass through while rejecting contaminants. Clean water is stored or delivered directly to the faucet, while wastewater is flushed away through the drain line. The result is purified drinking water with significantly reduced impurities.
Why is there “wastewater” in an RO system?
Why is there “wastewater” in an RO system?
Reverse osmosis produces “wastewater” because the system needs to flush away the contaminants it removes from your tap water.
During filtration, water is pushed through a membrane that blocks the impurities. The clean water passes through, while the concentrated contaminants must be carried out of the system through a small stream of “wastewater”.
This rinse water is essential. It prevents buildup on the membrane, keeps filtration performance high, and helps extend the life of the RO system.
