Membrane filtration spectrum
Membranes are widely used to purify water. A membrane is a special designed thin film which allows certain sized matter to pass through whilst others are rejected. We call this the permeability of the membrane. Membrane technology has allowed for increased efficiency in purification and nowadays even bacteria & viruses can be filtered out of the contaminated water. Moreover, membrane technology combined with specific pressure allows for the principle of reverse osmosis a technique widely used for desalination of seawater. See overview of the FILTRATION SPECTRUM for membranes.
- Particle filtration: for Macro particle range (human hair & fine sand)
- Reverse Osmosis: for Ionic range (aqueous salts)
- Nanofiltration: for Molecular range (pesticide, herbicide)
- Ultrafiltration: for Macro Molecular range (viruses)
- Microfiltration: for Micro particle range (bacteria)
The specific membrane to be applied has a close relationship with the necessary level of filtration and required composition of the product water. This means not only the pore-sizes differ across the spectrum, but usually also flow pattern and pressures.
