A High Efficiency Magnetic Activated Sludge Reactor for Wastewater Processing

Concept of aeroponic biomass cultivation and biological wastewater treatment system in extraterrestrial human base

“…Another issue in space biological wastewater treatment system is separation and recirculation of recycled sludge, which might be impeded due to decreased or lack of sedimentation (lack or lower gravity). For this purpose activated sludge is supplemented with magnetite (ferromagnetic powder) [19]. Separation is conducted in magnetic separator, where sludge is captured by magnetic forces.…”
