PHA and EPS production from industrial wastewater by conventional activated sludge, membrane bioreactor and aerobic granular sludge technologies: A comprehensive comparison

A Mini Review on Sewage Sludge and Red Mud Recycling for Thermal Energy Storage

“…SS with industrial wastewater sludge may contain more complex components such as heavy metals, inorganic salts, organic matter, grease, etc., which makes the mixed sludge require more professional and refined methods in treatment and disposal [72]. In addition, mixed sludge containing industrial wastewater sludge may be more toxic or hazardous, which increases the difficulty of sludge treatment and may pose a greater potential risk to the environment [73].…”

“…Energies 2024, 17, x FOR PEER REVIEW 6 more toxic or hazardous, which increases the difficulty of sludge treatment and may a greater potential risk to the environment [73]. more toxic or hazardous, which increases the difficulty of sludge treatment and may pose a greater potential risk to the environment [73]. Briefly, the basic characteristics of SS are mainly reflected in its high organic matter content, fine particles, small density, high moisture content, and being not easy to dewater, which determines that the treatment and disposal of sludge need to consider its dewatering performance and possible environmental problems.…”

Iron-Based Catalysts Derived from Iron-Containing Sludge for Enhanced Catalytic Performance of H2S Selective Catalytic Oxidation

“…In recent years, with the increase in the use of chemical raw materials and industrial additives in chemical synthesis, it has become increasingly difficult to treat industrial wastewater. − Faced with the raised emission standards, traditional secondary biochemical treatment can no longer meet the new emission requirements. Therefore, it is necessary to add some advanced treatment to meet the new high-standard emission requirements. , Among them, Fenton oxidation technology was widely used in deep treatment .…”
