What is Reverse Osmosis?
Reverse Osmosis (RO) is a membrane separation water purification process in which feed water flows along the membrane surface under pressure. Purified water permeates the membrane and is collected, while the concentrated water, containing dissolved and undissolved material that does not flow through the membrane, is discharged to the drain.
The key requirements of Reverse Osmosis (RO) process are a membrane and water under pressure. Other requirements include prefiltration to remove suspended impurities and carbon to remove chlorine (damages the membrane).
Most membranes remove 90-99+ % of the dissolved impurities depending on the impurity and the composition of water.
Reverse Osmosis, combined with pre-filtration, is able to remove 90 to 99.99% of the dissolved impurities that reside in your water.
Reverse osmosis systems (RO Systems) remove salts, microorganisms and many high molecular weight organics. System capacity depends on the water temperature, total dissolved solids in feed water, operating pressure and the overall recovery of the system.
How does a reverse osmosis system work?
A reverse osmosis system removes sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to remove dissolved solids. After water exits the RO membrane, it passes through a postfilter to polish the drinking water before it enters a dedicated faucet. Reverse osmosis systems have various stages depending on their number of prefilters and postfilters.
Stages of RO systems
The RO membrane is the focal point of a reverse osmosis system, but an RO system also includes other types of filtration. RO systems are made up of 3, 4, or 5 stages of filtration.
Every reverse osmosis water system contains a sediment filter and a carbon filter in addition to the RO membrane.The filters are called either prefilters or postfilters depending on whether water passes through them before or after it passes through the membrane.
Each type of system contains one or more of the following filters:
Sediment filter: Reduces particles like dirt, dust, and rust
Carbon filter: Reduces volatile organic compounds (VOCs), chlorine, and other contaminants that give water a bad taste or odor.
Semi-permeable membrane: Removes up to 98% of total dissolved solids (TDS)
When water first enters an RO system, it goes through prefiltration. Prefiltration typically includes a carbon filter and a sediment filter to remove sediment and chlorine that could clog or damage the RO membrane.
Next, water goes through the reverse osmosis membrane where dissolved particles, even too small to be seen with an electron microscope, are removed.
After filtration, water flows to the storage tank, where it is held until needed. A reverse osmosis system continues to filter water until the storage tank is full and then shuts off.
As there has water level alarm installed inside pure water tank,when the pure water level is below the min limit,the floating level switch will goes up,then the pump will start to operate RO system to produce pure water till water level above alarming line.
How to reduce wastewater in an RO system ?
Add a permeate pump. Installing a permeate pump to a reverse osmosis system is the best way to increase its efficiency. Permeate pumps reduce the wastewater from an RO system by 75 to 80%. Not every reverse osmosis system is designed to use one, so make sure the one you choose is plumbed for an additional pump.
Choose an RO system with an automatic shut off valve. a solenoid valve stops the flow of water to the drain once the storage tank is full.
Use the RO reject water for landscaping or artificial lakes. Drain water has higher levels of total dissolved solids (TDS), but it's safe to use in your lawn or garden.
Is reverse osmosis good for the environment?
When the water you use drains from your home, chemicals and other contaminants must be removed before it's recycled. Wastewater is either sent to a water treatment plant and diluted to make it easier to treat or to riverbeds for nature to filter through the hydrologic cycle.
A reverse osmosis system makes waste treatment more efficient. Reverse osmosis water drained from your home is already free of chemicals since they've been removed in the carbon filtration stage. The leftover brine water has just a slightly higher concentration of dissolved inorganics. RO systems speed up the recycling process because no new chemicals are introduced into the water supply after RO water drains from your house.
