An advanced pretreatment strategy involving hydrodynamic and acoustic cavitation along with alum coagulation for the mineralization and biodegradability enhancement of tannery waste effluent

•Pretreatment of Tannery waste effluent using alum coagulation followed by cavitation.•Hydrodynamic cavitation (HC) along with coagulation enhanced the BI from 0.14 to 0.57.•HC with coagulation enabled 75% and 73.4% reduction in COD and TSS respectively.•HC was six times more energy efficient as com...
