  • Characteristics of flux and gel layer on microFilter and non-woven Fabric Filter surface based on anoxic–aerobic MBRs
    Bioprocess and Biosystems Engineering, 2012
    Co-Authors: Bo-kyung Choi, Sung Kyu Maeng, Kyung Guen Song
    Abstract:

    Non-woven Fabric Filter- (NWFF) and microFilter-MBR modules were made using 100 μm polypropylene and 0.25 μm polyethylene materials, respectively. The performances and mechanisms of the two processes were investigated, including additional batch filtration tests to find the function of the dynamic gel layer on the membrane surface. The HRT of both MBRs was 9 h and the operating permeate flux was 13 L/m^2/h. The two MBRs consisted of an anoxic and aerobic reactor. The NWFF or microFilter (MF) was submerged in each of the aerobic reactors. The two MBRs showed similar performances for the removal of organic matters, suspended solids and nitrogen. Cake formation on the NWFF contributed to major resistance, while the gel layer on the microFilter or internal fouling of the pores played a key role in the fouling of the membrane surface. The amount of soluble extracellular polymer substances (EPS) (13 mg/L) of the attached sludge on the NWFF surface was larger than that (11 mg/L) of that suspended sludge. Consequently, the functional gel layer for the coarse and microFilter is established based on the relationship among the EPS, transmembrane pressure and MLSS.

  • modeling the filtration process with a flat type Fabric Filter
    Advanced Powder Technology, 2006
    Co-Authors: Yoshio Otani, Chikao Kanaoka
    Abstract:

    Abstract The Fabric filtration process is divided into three stages, i.e. depth filtration, transition filtration and surface filtration. A new model is proposed to describe the three stages under both virgin and regeneration conditions. The concept of an interface dust layer is introduced to predict the transition from the depth filtration stage to the transition filtration stage. The transition filtration stage due to the non-uniform accumulation of residual dust on a Filter is characterized by two parameters — the surface cleaning fraction, f, and the residual dust load on the uncleaned surface, W u0 . It is found that f decreases and W u0 increases with the number of filtration cycles. This result suggests that both the fraction of uncleaned surface and the thickness of dust cake on the uncleaned surface increase with the number of filtration cycles. The present model successfully describes the change in pressure drop during the filtration cycles using the parameters.
