2. Membrane bioreactor - Wikipedia

   en.wikipedia.org/wiki/Membrane_bioreactor

   Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. [1] The two basic membrane bioreactor configurations are the submerged ...

3. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   Reverse osmosis. Reverse osmosis ( RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances (principally ...

4. Desalination - Wikipedia

   en.wikipedia.org/wiki/Desalination

   Knowledge of the thermodynamics of steam processes and the need for a pure water source for its use in boilers generated a positive effect regarding distilling systems. Additionally, the spread of European colonialism induced a need for freshwater in remote parts of the world, thus creating the appropriate climate for water desalination.

5. Moving bed biofilm reactor - Wikipedia

   en.wikipedia.org/wiki/Moving_Bed_Biofilm_Reactor

   Alternative Wastewater Treatment Systems. There are many alternative wastewater treatment systems that can be used in place of MBBRs. The selection of the appropriate system depends on the wastewater coming in, treatment objectives, available space, and budgets. Some other options are: Sequencing Batch Reactors (SBR) Membrane Bioreactors (MBRs)

6. Microfiltration - Wikipedia

   en.wikipedia.org/wiki/Microfiltration

   Microfiltration. Microfiltration is a type of physical filtration process where a contaminated fluid is passed through a special pore-sized membrane filter to separate microorganisms and suspended particles from process liquid. It is commonly used in conjunction with various other separation processes such as ultrafiltration and reverse osmosis ...

7. Secondary treatment - Wikipedia

   en.wikipedia.org/wiki/Secondary_treatment

   Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [1] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
