Study and Application status of Biomagnetic effect in Wastewater Treatment

Compared with conventional activated sludge system, applied magnetic field or adding magnetic materials in activated sludge system exhibits a better performance of enzyme activity, sludge settling, microbial activity. It also shows an obvious influence on bacterial activity, dissolved oxygen and pollution loadings. Even more, the removal efficiency of organic pollutions, N and P in this system shows an obvious increase. The biomagnetic effect is a promising technology in wastewater treatment.
