Characteristics and potential treatment technologies for different kinds of wastewaters

Abstract EN

The current work was aimed to characterize and defining appropriate treatment processes for various types of raw wastewaters.

the fresh wastewater samples were collected from slaughterhouse (SWW), tannery (TWW), municipal (MWW), municipal landfill leachate (MLL), and dairy (DWW).

the collected samples were analyzed for temperature, pH, electrical conductivity, turbidity, total alkalinity, total hardness, biological and chemical oxygen demands, suspended and dissolved solids etc.

Commonly, MLL contained low biodegradability ratio; while SWW, MWW, and DWW had high biodegradability ratio of greater than 0.5.

TWW regarded as strong alkaline because pH values were greater than 10.

physical, chemical and biological treatment processes were explained and suitable treatment methods were complemented with the wastewater type.

It can be concluded that generally physical-chemical techniques were fit with old landfill leachate and tannery wastewaters; whilst biological treatment methods with adsorption were adequate for SWW, MWW, and DWW and the effluents match the quality of irrigation water quality.
