Abstract:
Due to climate change and excessive use of freshwater resource, countries are searching for new
techniques to reuse and recycle wastewater. The majority of Muslim countries are suffering from lack of water
resources, many of them are using desalination of sea water techniques for their daily needs. Abulation water
belongs to the category of greywater that is taking increasing attention. It constitutes 61% of the total
wastewater and is less polluted then blackwater. More than 20 techniques were made and most of them were
studied deeply, however in order to choose one technique we should take into consideration efficiency and
economical aspect. In this article, we identified and compared most of techniques used for treating greywater.
As a conclusion, slanted soil, constructed wetlands and biochar had the best elimination percentages in
filtration, treatment systems and medias used in these systems respectively.
