The application of magnetic nano-photocatalysts in clean water technologies, has been widely studied due to their improved chemical and physical properties. Due to the incorporation of magnetic materials into the nano-photocatalysts, the separation of the resultant nanocomposite can be facilitated via an applied external magnetic field, leading to more economic and also more ecologically friendly water refinement procedure. This paper presents a short review of magnetic nanomaterials in the purification of contaminated water/wastewater.

This study was performed to evaluate the efficiency of tapioca processing wastewater treatment using aerobic biofilter with variety of biofilter media: coir, coal, PVC plastic and Bio - Ball BB15 plastic. Research results in the lab demonstrated all four aerobic biofilter models processed can treated completely N and COD which COD reached 90-98% and N reached 61-92%, respectively, at the organic loading rates in range of 0.5, 1, 1.5 and 2 kgCOD/m3.day. The results identified coir filter was the best in four researched materials with removal COD and specific substract utilization rate can reach 98%, and 0.6 kg COD/kgVSS.day. Research results open the new prospects for the application of the cheap materials, available for wastewater treatment.
