An RO (Reverse Osmosis) Plant is a water purification system that uses a process called reverse osmosis to filter out impurities, contaminants, and unwanted minerals from water. The system works by forcing water through a semipermeable membrane, which allows water molecules to pass through while blocking larger particles like salts, chemicals, and bacteria.
Here’s a breakdown of how an RO plant works:
1. **Pre-filtration**: Water is passed through pre-filters to remove larger particles like sand, dirt, and chlorine, which can damage the RO membrane.
2. **High-pressure pump**: Water is then pressurized and forced through the semipermeable membrane.
3. **RO Membrane**: The core component of the plant where the actual separation of dissolved contaminants occurs. The membrane blocks impurities, allowing only clean water (permeate) to pass through, while rejecting contaminants (concentrate or brine).
4. **Post-filtration**: After passing through the membrane, the purified water may go through additional filtration stages, such as activated carbon filters, to improve taste and remove any residual impurities.
5. **Storage and distribution**: The clean water is stored in tanks for distribution, while the rejected water is usually discarded or used for other purposes.
### Applications of RO Plants:
- **Drinking water purification**: Common in households, businesses, and communities to provide clean drinking water.
- **Industrial applications**: Used in industries like pharmaceuticals, food and beverage production, and power plants to produce high-purity water.
- **Desalination**: RO plants are widely used in coastal areas to desalinate seawater, turning it into potable water.
