Speech Title: Treatment of industrial wastewaters by fluidized-bed technology
Abstract: Fenton process has been proven to be effective in the treatment of recalcitrant organic compounds. One disadvantage, however, is the production of a large amount of sludge that needs further treatment and disposal. The production of sludge is reduced by the use of fluidized-bed Fenton (FBF) process where iron is crystallized onto the surface of the carriers in the reactor. An overview of the recent developments on the application of FBF process to the treatment of industrial wastewater will be presented. The advantages of FBF process over other technologies that are based on Fenton oxidation in terms of performance, operating conditions and factors affecting the removal efficiency will be highlighted. Included also will be the reaction kinetics and mechanisms involved and the carriers that were used. Finally, large-scale applications will be presented and described.
Furthermore, the fluidized-bed technology can be also applied for metal ion recovery such as nickel and copper with homogeneous crystallization. This technology overcomes the limit of adding carriers at the initial operation stage. By changing the operation conditions and reactor design, crystals are formed in the reactor directly. The process can produce granules with high purity and therefore has potential to be applied in product synthesis and wastewater treatment. There are several advantages: (1) saving space, (2) reducing sludge, (3) cost down, (4) higher efficiency. Compared with conventional heterogeneous process, this new one can generate high-purity products and therefore it is easy to be applied in future.
