Multi grade Sand Filters
Multi grade Sand Filters use different grades of similar media in fixed ratio. The use of similar media in different grades creates a bed with pores of different sizes. This helps in entrapment of the suspended particles in the media.
This filters can be operated at higher specific surface flow rates. Hence the size of the filters can be smaller and quality of effluent will be superior.
