Enhanced treatment of landfill leachate wastewater using sono(US)-ozone(O3)–electrocoagulation(EC) process: role of process parameters on color, COD and electrical energy consumption

[Display omitted] •Combination of US, O3 and EC process for removal of color, COD with electrical energy consumption from landfill leachate was developed.•US/O3/EC was highly successful in removal of color and COD than other hybrid and single processes such as O3/EC, US/EC, US/O3 and EC, O3, US.•Max...
