AbstractCeramic-based photocatalytic membrane reactors (cPMRs) are becoming increasingly popular among researchers and will soon be seen on the water/wastewater-treatment market. This review provides a thorough analysis of the available data on cPMRs fabricated to date based on coating method, support and coating materials, membrane design, pore size and model compounds used to evaluate process efficiency and light source. While all of the studies describe cPMR preparation in great detail, over half do not provide any information about their performance. The rest used various dyes that can be conveniently detected by spectrophotometry/fluorimetry, or micropollutants that require analytical equipment available only in specialized laboratories. In addition, cPMRs are viewed as a convenient way of incorporating a photocatalyst on an inert surface assuming that the surface itself, i.e. the membrane, does not participate in the treatment process. A unified test for cPMR performance should be developed and implemented for all cPMRs that have the potential for commercialization. There is a need for standardization in cPMR testing; only then can the true performance of cPMRs be evaluated and compared. Such testing will also answer the question of whether the cPMR membrane is indeed an inert support or an active part of the treatment process.

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.
