    Notes: Summary Brewery effluent with high organic content was treated anaerobically in a 1.17 m3 reactor over five months. At 26°C, and with a HRT of 13.3 hrs and a loading rate of 4.9 kg COD/m3d, the process reduced over 89% of COD and 92% of BOD5 from the brewery effluent; both reductions could be further improved by more effective removal of suspended solids.

    Notes: Summary Phenolic pollutants were toxic to the bioactivity of anaerobic benzoate-degrading granules. Cresols were more toxic than phenol, which in turn was more toxic than dihydroxybenzenes. The toxicity was dependent on the hydrophobicity of the functional group, but not their positions. The granules exhibited mild resistance to the toxicity of phenolic pollutants, probably because of their layered microstructure.

    Notes: Summary Photos of scanning and transmission electron microscopy showed that sludge granules treating sucrose wastewater had a 20–40 μm surface layer with diverse morphology, consisting of cocci and bacilli, and a loosely packed interior, mainly consisting of Methanothrix. Light microscopy using epi-fluorescent excitation showed not only the similar microstructure, but also the distribution of various genuses of methanogens.

    Notes: Summary Two types of anaerobic sludge were analyzed for ECP (extracellular polymers) content under five extraction conditions. Results showed that EDTA was more effective than formaldehyde as an extractant. Increase of temperature and addition caustic also enhanced the extraction. The ratio between carbohydrate and protein fractions of ECP for both acetate- and benzoate-degrading sludge was 0.16–0.18. The former sludge had only 40–45% of ECP as in the latter sludge.

    Notes: Summary Wastewater from a dairy plant with an average BOD5 of 1060 mg/l and an average TKN of 109 mg/l was treated aerobically using three activated sludge reactors in series. With an overall retention time of 19.8 hrs, the final effluent contained 9 mg/l of BOD5 and 10 mg/l of TKN, corresponding to respective reductions of 99% and 91%.

    Notes: Summary Heavy metals in electroplating effluent inhibited specific methanogenic activity (SMA) of anaerobic starch-degrading granules. The SMA of granules on the degradation of starch were reduced by 50% when each gram of biomass was in contact individually with 105 mg of zinc, 120 mg of nickel, 180 mg of copper, 310 mg of chromium, or 〉400 mg of cadmium. Granules had higher toxicity-resistance than flocculent sludge, due to their layered structure.

    Notes: Summary Biogranules developed in the upflow anaerobic sludge blanket (UASB) reactors were analysed by X-ray spectrometry for the local concentration of individual inorganic elements and by X-ray dot mapping for the pictorial distribution of these elements in the cross-section of the biogranules. This information is of significance for the understanding of the sludge granulation mechanism and the role of inorganic elements.

    Notes: The order of ion separation by the NS-100 membrane differed slightly from that of the cellulose acetate membrane. The separation of an ion by the NS-100 membrane increased with increase in the valence of the ion, but decreased with the increase in the ionic radius. The sole criterion determining this separation order for the NS-100 membrane was the enthalpy of hydration. An ion having a higher enthalpy of hydration is bulkier in the hydrated form and is, therefore, separated more effectively by the NS-100 membrane, according to the diffusional model of solute separation. The permeability of an ion through the membrane material can be related to its enthalpy of hydration. By using this relationship, the separation of individual ions in aqueous solution with a given NS-100 membrane can be predicted from a test with a sodium chloride solution.
