Recycling Thermal-Alkaline Waste Activated Sludge Lysate for Coupled Sulfate Reduction and Nitrate Transformation: Performance, Ammonium Accumulation, and Microbial Insights
Waste activated sludge (WAS) is a carbon-rich residual biomass that can be converted into a recycled carbon source for biological wastewater treatment; however, the applicability of low-temperature thermal-alkaline WAS lysate to coupled sulfate reduction and nitrate transformation remains unclear. This study optimize...
