Water recovery from sewage using forward osmosis
This research is part of the Sewer Mining project aimed at developing a new technological concept by extracting water from sewage by means of forward osmosis (FO). FO, in combination with a reconcentration system, e.g. reverse osmosis (RO) is used to recover high-quality water. Furthermore, the subsequent concentrated sewage (containing an inherent energy content) can be converted into a ...

How is Reverse Osmosis Desalination Used in Tertiary Sewage Treatment Applications?
Salts and other dissolved solids can be pretty tricky to remove from wastewater streams. Standard filtration doesn’t really do anything about dissolved solids and neither does coagulation or sedimentation. They might manage to remove some, but in situations where total dissolved solids (TDS) are particularly high, those sorts of treatments do not lower TDS enough to be compliant or to reuse ...

Removal of Cd(II) ions from aqueous solution and industrial effluent using reverse osmosis and nanofiltration membranes
Industrial effluents loaded with cadmium have contributed to the pollution of the environment and health troubles for humans. Therefore, these effluents need treatment to reduce cadmium concentration before releasing them to public sewage. The purpose of the research is to study the major role of reverse osmosis (RO) and nanofiltration (NF) processes, which can contribute to the removal of ...

Effective products for wastewater treatment system
The process applied to alter waste water into dirt-free drinking water is called as WasteWater Treatment; the water that is no longer needed or fit for any purpose. The bilge water can be returned to the water cycle to make it suitable for drinking. This is called as water reclamation which avoids the disposal of wastewater by treating them with various recycling processes. Treatment implies to ...
