Recalcitrant Industrial Wastewater Treatment By Membrane Bioreactor (Mbr), Faisal I. Hai, Kazuo Yamamoto, Fumiyuki Nakajima, Kensuke Fukushi

Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. The membrane is an absolute barrier to suspended matter and microorganisms and it offers the possibility of operating the system at high mixed liquor suspended solids (MLSS) concentration. The implication of maintenance of high MLSS are— requirement of a smaller footprint and operation at high solids retention time (SRT) under low F/M ratio, hence, yielding reduced excess sludge. Operating as an MBR allows conventional activated sludge plants to become single step processes, …

Suitability Of Membrane Bioreactor For Treatment Of Recalcitrant Textile Dye Wastewater Utilising White-Rot Fungi, Faisal Hai, Kazuo Yamamoto
Suitability Of Membrane Bioreactor For Treatment Of Recalcitrant Textile Dye Wastewater Utilising White-Rot Fungi, Faisal Hai, Kazuo Yamamoto
Faisal I Hai
The performance of a laboratory scale membrane bioreactor (MBR) — utilizing a mixed microbial community dominated by fungi— for treatment of textile dye wastewater was investigated. A synthetic wastewater containing dye, starch (main contributor to total organic carbon, TOC) and other nutrients was used. Preliminary batch tests confirmed the superior decoloration capacity of pure fungus culture (Coriolus versicolor, NBRC 9791) as compared to that of conventional activated sludge. Simultaneous biosorption and biodegradation was evident in case of the fungus, while mainly biosorption was responsible for decoloration by activated sludge. On the other hand, activated sludge demonstrated comparatively faster TOC removal. …

White-rot fungi, unlike bacteria in conventional activated sludge system, can degrade wide varieties of textile dyes. Their large scale implementation, however, has been impeded due to lack of appropriate reactor system that can sustain stable performance under non-sterile environment. In this study, contrary to virtually complete decoloration of an azo dye (Acid Orange II, 100 mg L−1) in pure culture batch test, a fungal membrane bioreactor (MBR) achieved 93% removal during long-term non-sterile operation at a hydraulic retention time (HRT) of 1 d. Through a set of novel observations made in MBR and parallel batch tests, the interrelated factors responsible …
Different Fouling Modes Of Submerged Hollow-Fiber And Flat-Sheet Membranes Induced By High Strength Wastewater With Concurrent Biofouling, Faisal I. Hai, Kazuo Yamamoto, Kensuke Fukushi
Different Fouling Modes Of Submerged Hollow-Fiber And Flat-Sheet Membranes Induced By High Strength Wastewater With Concurrent Biofouling, Faisal I. Hai, Kazuo Yamamoto, Kensuke Fukushi
Faisal I Hai
Exploration of two major commercialized flat-sheet and hollow-fiber membranes in a submerged membrane fungi reactor fed with a synthetic textile wastewater revealed striking differences in the extent and mechanism of fouling between the two types, indicating a case-specific scope of choice between the two for industrial wastewater treatment. The hollow-fiber membrane exhibited fouling with a cake layer composed of fungi and starch, intensity being proportional to the operating flux (0.05–0.3 m/d). Conversely, the flat-sheet membrane suffered from immediate internal pore blocking beyond a critical flux of 0.2 m/d. During the experiment with major constituents of the synthetic wastewater separately, while …

Faisal I Hai
The long-term performance of a submerged membrane fungi reactor was observed while a synthetic textile wastewater containing either or both of the two structurally different azo dyes was continuously fed. Compared to the Acid Orange II dye (simpler structure), higher biosorption but slower biodegradation of the polymeric dye (Poly S119) was observed in sterile batch tests. In the membrane bioreactor (MBR), although a relative abundance of fungi (66%) without any specific control of bacterial contamination could be maintained, unlike in pure fungus culture, enzymatic activity was below detection limit. Nevertheless, >99% removal of Poly S119 was consistently achieved under a …

Contemporary lipidomics protocols are dependent on conventional tandem mass spectrometry for lipid identification. This approach is extremely powerful for determining lipid class and identifying the number of carbons and the degree of unsaturation of any acyl-chain substituents. Such analyses are however, blind to isomeric variants arising from different carbon−carbon bonding motifs within these chains including double bond position, chain branching, and cyclic structures. This limitation arises from the fact that conventional, low energy collision-induced dissociation of even-electron lipid ions does not give rise to product ions from intrachain fragmentation of the fatty acyl moieties. To overcome this limitation, we have …
Pyrolysis Of Fulvenallene (C7h6) And Fulvenallenyl (C7h5): Theoretical Kinetics And Experimental Product Detection, Adam Trevitt, G Da Silva, M Steinbauer, P Hemberger
Pyrolysis Of Fulvenallene (C7h6) And Fulvenallenyl (C7h5): Theoretical Kinetics And Experimental Product Detection, Adam Trevitt, G Da Silva, M Steinbauer, P Hemberger
Adam Trevitt
Fulvenallene and fulvenallenyl are the respective C7H6 and C7H5 global minima, yet their importance to combustion has only recently emerged. We have studied the pyrolysis of these species theoretically to obtain rate constants and compare our results to pyrolysis mass spectrometry experiments for product identification. Master equation modeling reveals that fulvenallene rapidly dissociates to fulvenallenyl + H, and that fulvenallenyl dissociates to form propargyl plus diacetylene, with lesser amounts of i-C5H3 (CH2CCCCH)/n-C5H3 (CHCCHCCH) plus acetylene. Photoionization mass spectrometry experiments using a pyrolysis source on the fulvenallene precursor phthalide identify products consistent with those proposed theoretically for both fulvenallene and fulvenallenyl …

Comment On The Ionization Energy Of B2f4, Bun Chan, Adam J. Trevitt, Stephen J. Blanksby, Leo Radom
Adam Trevitt
The Gn test sets(1) of accurate (uncertainty ≤ 1 kcal mol–1 ≈ 4 kJ mol–1) experimental data are widely employed in the development and assessment of quantum chemistry procedures. However, while all the data in the Gn sets nominally carry a sub-kcal mol–1 uncertainty, several of the experimental values show uncharacteristically large discrepancies when compared with values determined by high-level theoretical calculations. One of these questionable values is the adiabatic ionization energy (IE) of B2F4, for which the theoretical values calculated, for example, with the high-level G2 (1133.9, kJ mol–1),(1b) G3 (1135.4 kJ mol–1),(2) and G4 (1127.2 kJ mol–1)(3) procedures …

Reactions Of Small Carbon-Bearing Radicals With Unsaturated Hydrocarbons: Product Detection And Low Temperature Kinetics, Adam Trevitt, Fabien Goulay, Stephen Leone
Adam Trevitt
We report on results from two experimental techniques concerned with the reactions of small carbon based radicals (CN and CH) with unsaturated hydrocarbons. First, low temperature (100-300K) kinetic studies using a pulse Laval nozzle technique probe the reactions of the CN radical with benzene and toluene. The CN + benzene is found to be a fast, barrierless reaction. But in the case of toluene, two reaction pathways are in competition, one of which back dissociates to the reactants. The implications for the atmosphere of Titan are discussed. Product detection studies undertaken at the Advanced Light Source (ALS) using synchrotron coupled …

The gas-phase CN + propene reaction is investigated using synchrotron photoionization mass spectrometry (SPIMS) over the 9.8 - 11.5 eV photon energy range. Experiments are conducted at room temperature in 4 Torr of He buffer gas. The CN + propene addition reaction produces two distinct product mass channels, C3H3N and C4H5N, corresponding to CH3 and H elimination, respectively. The CH3 and H elimination channels are measured to have branching fractions of 0.59 + 0.15 and 0.41 + 0.10, respectively. The absolute photoionization cross sections between 9.8 and 11.5 eV are measured for the three considered H-elimination coproducts: 1-, 2-, and …

Adam Trevitt
Aromatic radicals form in a variety of reacting gas-phase systems, where their molecular weight growth reactions with unsaturated hydrocarbons are of considerable importance. We have investigated the ion–molecule reaction of the aromatic distonic N-methyl-pyridinium-4-yl (NMP) radical cation with 2-butyne (CH3C≡CCH3) using ion trap mass spectrometry. Comparison is made to high-level ab initio energy surfaces for the reaction of NMP and for the neutral phenyl radical system. The NMP radical cation reacts rapidly with 2-butyne at ambient temperature, due to the apparent absence of any barrier. The activated vinyl radical adduct predominantly dissociates via loss of a H atom, with lesser …

The Geomorphological Evolution Of A Wave-Dominated Barrier Estuary: Burrill Lake, New South Wales, Australia, Brian G. Jones, Craig R. Sloss, David M. Price, C.E. Mcclennen, John De Carli
B. G. Jones
The geomorphological evolution of the Holocene wave-dominated barrier estuary at Burrill Lake on the New South Wales coast, Australia, has been delineated using a combination of seismic stratigraphy and the lithostratigraphic analysis of vibracores collected from the back-barrier estuarine environment. A combination of radiocarbon and aspartic acid racemisation-derived ages obtained on Holocene fossil molluscs, and the thermoluminescent signal in remnant Last Interglacial barrier sediments provides the chronological framework for this investigation. Results from this paper show that the barrier estuary occupies a relatively narrow (<1.5 km wide) and shallow (<40 m deep) incised bedrock valley formed during sea-level …

Jones, Stuart C. Tye, James A. Maceachern, Kerrie L. Bann, Christopher R. Fielding
B. G. Jones
The Lower Permian (Artinskian to Sakmarian) Pebbley Beach Formation of the southernmost Sydney Basin in New South Wales, Australia, records sediment accumulation in shallow marine to coastal environments at the close of the Late Palaeozoic Gondwanan ice age. This paper presents a sequence stratigraphic re-evaluation of the upper half of the unit based on the integration of sedimentology and ichnology. Ten facies are recognized, separated into two facies associations. Facies Association A (7 facies) comprises variably bioturbated siltstones and sandstones with marine body fossils, interpreted to record sediment accumulation in open marine environments ranging from lower offshore to middle shoreface …

Optically stimulated and thermoluminescence ages from relict shorelines, along with accelerator mass spectrometer 14C ages from freshwater molluscs reveal a record of variable moisture sources supplied by northern and southern river systems to Lake Mega-Frome in southern central Australia during the late Quaternary. Additional lacustrine, palynological and terrestrial proxies are used to reconstruct a record that extends back to 105 ka, confirming that Lakes Mega-Frome and Mega-Eyre were joined to create the largest system of palaeolakes on the Australian continent as recently as 50-47 ka. The palaeohydrological record indicates a progressive shift to more arid conditions, with marked drying after …

Environmental radionuclides can be employed as tracers of sediment movement and delivery to water bodies such as lakes and reservoirs. The chronologies of sediments that have accumulated in the Cordeaux reservoir in Sydney, Australia, were determined by the rate of change of 210Pbex with depth and indicate slow accretion in the reservoir. The ratio of enrichment of radionuclides in sediment cores to 210Pbex and 137Cs concentrations in a reference soil sample within the Cordeaux catchment indicates that the dominant source of sediment in the Cordeaux reservoir is surface erosion (detachment and removal of sediment at depths less than 30 cm). …
On The Possible Origins Of An Unusual (Mid To Late Holocene) Coastal Deposit, Old Punt Bay, South-East Australia, Brian Jones, Adam Switzer, S Haslett, Dale Dominey-Howes, D Everett, C Courtney, B Mamo, L Strotz
On The Possible Origins Of An Unusual (Mid To Late Holocene) Coastal Deposit, Old Punt Bay, South-East Australia, Brian Jones, Adam Switzer, S Haslett, Dale Dominey-Howes, D Everett, C Courtney, B Mamo, L Strotz
B. G. Jones
An unusual coarse, shelly sedimentary unit is found elevated above present mean sea level in a sheltered pocket embayment at Old Punt Bay in south-eastern Australia. The coarse sediments, diverse microfauna, and large shelly macrofauna of mixed affinity suggest that the deposit is the result of high-energy deposition. The deposit was previously thought to have been deposited 1000-1300 cal bp based on one shell dated using 14C and amino acid racemisation. However, additional 14C dating indicates a likely age of ~2500 cal bp. Regardless of age constraints, the presence of rock-encrusting oyster shells and large articulated bivalves, suggests that the …

B. G. Jones
In central Australia the most easterly extent of the MacDonnell Ranges borders the northwestern Simpson Desert where widely spaced strike ridges intercept the regional linear dunefield. Topographic basins have disrupted regional drainage lines and isolated dune sets from the main dunefield. In the western part of Camel Flat basin large, red coloured linear dunes of fine sand, ~ 74 ka and older, are oriented almost due north. Through gaps in the ranges the Todd River traversed the eastern part of the basin until ~25 ka when it apparently avulsed ~25 km eastwards to its present position. Subsequently, linear dunes, smaller, …

Patterns And Rates Of Sedimentary Infill In The Minnamurra River Estuary, South-Eastern Australia, K Panayotou, Colin Woodroffe, Brian Jones, Bryan Chenhall, Errol Mclean, H Heijnis
B. G. Jones
This paper presents a revised process-based model that explores aspects of estuarine geomorphology and the rates and patterns of sedimentary infill based upon the Minnamurra River estuary, a mature barrier estuary in south-eastern Australia. The Minnamurra River is located on the south coast of New South Wales and is characterised by three main facies: a marine flood tide delta/barrier, a central lagoon/estuary and a fluvial delta. The sedimentary record in this system was examined in detail to quantify the rate of estuarine infill. This predominantly infilled mature barrier estuary is now largely dominated by river influence. In the early stages …

Contrasting Sedimentation Rates In Lake Illawarra And St Georges Basin, Two Large Barrier Estuaries On The Southeast Coast Of Australia, Colin Murray-Wallace, Brian Jones, Craig Sloss, H Heijnis, B Brooke
B. G. Jones
Sedimentation rates over the last 100 years within two lagoons on the southeast coast of Australia, Lake Illawarra and St Georges Basin, have been quantified to determine the effects of catchment land use change and native vegetation clearance on infill rates, and spatial variations in the rate at which the estuaries have filled. Both catchments have similar lake and catchment area but have experience different degrees of modification due to land clearing for agriculture practices, urbanisation and industrialisation. Results indicate that in the heavily modified catchment of Lake Illawarra sedimentation rates close to fluvial deltas can be in excess of …
