Distillation involves the heating of water to create steam, which is then condensed back into liquid form, leaving contaminants behind. This method is highly effective for removing volatile compounds and is often used in conjunction with other technologies for more comprehensive purification.

3.3 Ultrafiltration (UF)
Ultrafiltration uses a membrane with smaller pores than those in reverse osmosis to separate particles and microorganisms from water. This technology is useful for treating water that contains suspended solids and is often used as a pre-treatment process before RO or distillation.

3.4 Nanofiltration (NF)
A type of membrane filtration, nanofiltration is used to remove multivalent ions and larger molecules from water. It is less restrictive than reverse osmosis, allowing for the passage of some monovalent ions and lower molecular weight compounds.

3.5 Membrane Bioreactors (MBR)
Membrane bioreactors combine biological processes with membrane filtration to treat wastewater. They are highly efficient in removing organic matter and nutrients, and are becoming increasingly popular for water reclamation and reuse.

3.6 Ion Exchange
Ion exchange is a process that involves the exchange of ions between a solution and a solid medium. This technology is used to remove specific ions, such as calcium and magnesium, from water, making it softer and more suitable for various applications.

3.7 Ultraviolet (UV) Disinfection
UV disinfection is a non-chemical method of killing or inactivating microorganisms in water. UV light damages the DNA or RNA of bacteria, viruses, and other pathogens, rendering them harmless.

3.8 Ozonation
Ozonation is a process that uses ozone, a powerful oxidant, to disinfect and remove organic compounds from water. It is often used as a pre-treatment or post-treatment process to enhance the effectiveness of other water treatment methods.

3.9 Electrodialysis
Electrodialysis uses an electric current to move ions through a series of ion-selective membranes, effectively separating them from water. This technology is particularly useful for removing salt from brackish water.

3.10 Advanced Oxidation Processes (AOPs)
Advanced oxidation processes involve the use of highly reactive chemical species, such as hydroxyl radicals, to break down organic compounds in water. AOPs are effective for treating water with complex or resistant contaminants.
