Description

Application

• Influence of toluene on the degradation of complex organic matter in wastewater treatment systems.: This study examines the impact of toluene on the degradation processes of complex organic matter in wastewater treatment systems. It highlights the inhibitory effects of toluene on microbial activity and proposes strategies to mitigate these effects to improve the efficiency of wastewater treatment (Taheri et al., 2022).
