Ozone and hydrogen peroxide pretreatment for enhancing the fermentation and the anaerobic digestibility of the municipal sludges
FY 2024-25
Summary
Wastewater treatment plants (WWTPs) are now confronted with limited space and aging infrastructure with limited volumetric capacity and required to expand their specific capacities to handle higher sludge volumes. The anaerobic digestion (AD) process is an integral part of WWTPs with the pivotal role of stabilizing the generated sludge and produce biogas (CH4, and CO2), contributing to environmental protection and energy recovery. However, the AD process is characterized with the slow kinetics of sludge hydrolysis which can be address by pretreatment of the feedstock of using the additives. In this proposal, the impact of ozone and hydrogen peroxide (H2O2) pretreatment on the dark fermentation and anaerobic digestibility of the municipal sludges (a mixture of primary sludge and thickened waste activated sludge) will be investigated. In this project, comparative studies will be carried out to evaluate efficiency gains and economic feasibility. This effort aims to inform engineering practitioners and plant operators with key pretreatment approaches, its feasibility, and limitations. The significance of this project goes beyond municipal wastewater sludge and blazes a trail for the adoption of innovative pretreatment approaches for different types of waste.
