Flocculation Process

Membrane bioreactor (MBR) has developed rapidly in recent years; however, the membrane fouling problems are affecting its further widespread application. This paper discusses the role of metal ions in the mixture in the mechanism; also on the high-priced metal ions coexist in the mixture when the effects of biological flocculation process; finally, the direction of future research in this area are summarized.

Ammonia Conversion

Partial nitrification (PN) was rapidly started-up in a sequencing batch membrane bioreactor (MBR) treating domestic wastewater with low temperature (11~15°C), the influence of alkalinity on PN process and the feasibility to control the ratio of nitrite to ammonia in effluent were investigated through changing the ratio of Alkalinity/ammonia in influent. Results showed that effluent ratio can be controlled flexibly with the liner relationship between ammonia conversion and the ratio of alkalinity to ammonia when alkalinity is insufficient, whereas, that could be effectively achieved by the indicator role of alkalinity on nitrite. Phylogenetic results indicated the predominance ofNitrosomonasand the absence of theNitrosospirain the condition of insufficient alkalinity, which was consistent with the SEM results. FISH results suggested that lack of alkalinity presented little impact on the relative quantity of AOB.
