Dye degradation has gained attention of late due to indiscriminate disposal from user industries. Enhancing efficiency of biological treatment provides a cheaper alternative vis-à-vis other advanced technologies. Dye molecules are metabolized biologically via anoxic and oxic treatments. In this study, bacterial community surviving on dye effluent working in anoxic–oxic bioreactor was analyzed using 16S rDNA approach. Azo-dye decolorizing and degrading bacterial community was enriched in lab-scale two-stage anoxic–oxic bioreactor. 16S rDNA metagenomic libraries of enriched population were constructed, screened and phylogenetically analyzed separately. Removal of ∼35% COD with complete decolorization was observed in anoxic bioreactor. Process was carried out by uncultured gamma proteobacterium constituting 48% of the total population and 12% clones having homology to Klebsiella. Aromatic amines generated during partial treatment under anoxic bioreactor were treated by aerobic population having 72% unculturable unidentified bacterium and rest of the population consisting of Thauera sp., Pseudoxanthomonassp., Desulfomicrobium sp., Ottowia sp., Acidovorax sp., and Bacteriodetes bacteriumsp.

Composite Wastewater Treatment by Aerated Electrocoagulation and Modified Peroxi-coagulation Processes(Chemosphere)
(Abhijeet Kumar, P. V. Nidheesh, M Suresh Kumar
,,, 587-593,Year : 2018)
|
Treatment of composite wastewater generating from the industrial estates is a great challenge. The present study examines the applicability of aerated electrocoagulation and modified peroxi-coagulation processes for removing color and COD from composite wastewater. Iron plates were used as anodes and cathodes in both electrochemical processes and experiments were carried out in a working volume of 2 L. Aeration enhanced the efficiency of electrocoagulation process significantly. More than 50% of COD and 60% of color were removed after 1 h of electrocoagulation process operated at pH 3 and applied voltage of 1 V. Eficiency of the modified peroxi-coagulation process was significantly higher than that of aerated electrocoagulation. COD and color removal efficiencies of the modified peroxi-coagulation process were found as 77.7% and 97%, respectively after 1 h of electrolysis operated at 1 V, solution pH 3 and 50 mM hydrogen peroxide addition. This improved eficiency of modified peroxi-coagulation compared to aerated electrocoagulation is mainly due to the attack of in-situ generated hydroxyl radicals.

Nutrient and enzyme mobilization in earthworm casts: A comparative study with addition of selective amendments in undisturbed and agricultural soils of a mountain ecosystem(International Biodeterioration & Biodegradation)
(Pooja Singh, Sudip Mitra, Deepanjan Majumdar, Pradip Bhattacharyya, Amit Prakash, Pallabi Borah, Ankita Paul, Latha Rangan,119,,437-447,Year : 2017)

Earthworms are known to bio-degrade various types of organic materials added or already present in soil. Two soils were collected from different land use patterns viz. an agricultural land (AL) and an undisturbed land (UL) of a mountain ecosystem of State of Himachal Pradesh in India for the present investigation. A laboratory microcosm study was carried out to elucidate effects of various agricultural soil amendments, viz. wood ash (WA), rice husk (RH), cow dung (CW) and their mixture (MA) applied @25 t ha_1, on selective biological and chemical properties of earthworm (Eisenia fetida) casts and growth in the collected soils. Subsequently, earthworms were reared in soils from both AL & UL, treated with the amendments; and the resultant earthworm cast (EwC) properties were found to be largely determined by the nature of amendments rather than land use types. Soils treated with MA produced casts displayed higher nutrient content, microbial biomass C with higher activities of dehydrogenase and urease. Earthworm growth and cast formation were greater in the soil from UL over soil from AL for all treatments except WA, implying better acclimatization and earthworm activity in the former. Further, casts produced under UL had higher nutrient mobilization and enzyme activity in comparison to AL. Results suggested that agricultural intervention in an undisturbed land might weaken its ability to support growth, development in conjunction with the activities of earthworms and associated enzymes.

Zooplankton diversity as indicators of pollution in warm monomictic Dal-Nigeen lake(Sustainable Water Resources Management)
(Dilip Meshram, D Catherine, N. Badhe, Snehal Khedkar, Ritesh Vijay Tapas Nandy ,4,4,897-904,Year : 2018)
|
The study aimed to assess the zooplankton diversity in Dal–Nigeen lake located in Srinagar, India. Zooplankton is a secondary producer which acts as the intermediate link between phytoplankton and fish in aquatic environment. Zooplankton diversity in the lake was monitored during autumn 2012 and summer 2013. Among zooplankton single species belonging to protozoa, 11 species to rotifera, 3 species to cladocera, and 2 species with single larval stage belonging to copepod were identified. Percent composition of zooplankton communities revealed that rotifera was the most dominant group followed by copepoda in summer, while rotifera was the most dominant group followed by cladocera in autumn season. The Shannon–Wiener diversity index (SWI) in summer varied from 1.29 to 3.63 and from 1.43 to 3.67 in autumn indicating moderate-to-good level of zooplankton diversity in the lake and low-to-medium impact of organic pollution from the anthropogenic activities. The study indicates that species abundance was lower in summer as compared to autumn season which may be due thereby to variation in environmental characteristics of the lake water.

(V. V. Khaparde, A. D. Bhanarkar, Deepanjan Majumdar, C. V. Chalapati Rao,562,,155-163,Year : 2016)
|
Fugitive emissions of PM10 (particles <10μm in diameter) and associated polycyclic aromatic hydrocarbons (PAHs) were monitored in the vicinity of coking unit, sintering unit, blast furnace and steel manufacturing unit in an integrated iron and steel plant situated in India. Concentrations of PM10, PM10-bound total PAHs, benzo (a) pyrene, carcinogenic PAHs and combustion PAHs were found to be highest around the sintering unit. Concentrations of 3-ring and 4-ring PAHs were recorded to be highest in the coking unit whereas 5-and 6-ring PAHs were found to be highest in other units. The following indicatory PAHs were identified: indeno (1,2,3-cd) pyrene, dibenzo (a,h) anthracene, benzo (k) fluoranthene in blast furnace unit; indeno (1,2,3-cd) pyrene, dibenzo (a,h) anthracene, chrysene in sintering unit; Anthracene, fluoranthene, chrysene in coking unit and acenaphthene, fluoranthene, fluorene in steel making unit. Total-BaP-TEQ (Total BaP toxic equivalent quotient) and BaP-MEQ (Total BaP mutagenic equivalent quotient) concentration levels ranged from 2.4 to 231.7ng/m(3) and 1.9 to 175.8ng/m(3), respectively. BaP and DbA (dibenzo (a,h) anthracene) contribution to total-BaP-TEQ was found to be the highest

Probability of Aluminium Toxicity from Bhandup Complex Water Treatment Plant, Mumbai: A Case Study(ASCE Practice Periodical of Hazardous, Toxic, and Radioactive Waste Management )
(Avick Sil, Kanchan Wakadikar, Sunil Kumar, Sivagami S.P.M, Shivani Dhage,Vol. 15(4),,,Year : 2010)
|
Bhandup Complex water treatment plant located in Mumbai, India, supplies water to most of Mumbai. The plant receives raw water from Vehar Lake. Alum has been used as a coagulant in the treatment process for the past 27 years. The backwashed water from the plant is released into Vehar Lake, which carries a significant amount of suspended matter. Therefore, a layer of sludge was deposited on the meeting point of backwashed water and Vehar Lake. The status of aluminum (Al) concentration in sludge deposits, banks, water, and sediment samples of Vehar Lake and its comparison with Al concentration of soil in the area surrounding the plant is presented in this paper. The comparison showed that the surrounding soil samples had the least Al concentration (16,394–26,081??mg/kg26,081??mg/kg), whereas the highest values of 53,882–73,382??mg/kg73,382??mg/kg and 62,096–76,496??mg/kg76,496??mg/kg were reported in upper and lower layers of sludge, respectively. This paper also discusses the detrimental effect of Al when it is available in toxic form at acidic pH.

Efficient removal of Brilliant Blue G (BBG) from aqueous solutions by marine Aspergillus wentii: Kinetics, equilibrium and process design(Ecological Engineering)
(Yasmin Khambhaty, Kalpana Mody,,, 74-83,Year : 2012)
|
|
The sorption of Brilliant Blue G (BBG) by dead biomass of marine fungus Aspergillus wentii, which was chemically modified by esterification of the carboxylic acids (CB), or methylation of amine (NB), or raw biomass (RB) was studied with variation in the parameters of contact time (0–80 min), initial concentration of dye (119.3–544.8 mg/L) and solution pH (2–10). The contact time necessary to reach equilibrium was 180 min. The BBG biosorption was strictly pH dependent, and maximum uptake capacity of all three biosorbents was observed at initial pH 2. The biosorption isotherm data were fitted well to the Langmuir isotherm and the monolayer sorption capacity was found to be 384.6, 370.4 and 312.5 mg/g for CB, NB and RB, respectively. For each biosorbent-dye system, kinetic models were applied to the experimental data to examine the mechanisms of sorption and potential rate-controlling steps. The pseudo-second-order kinetic model described the biosorption kinetics accurately and the sorption process was found to be controlled by pore and surface diffusion. From the design of a single-batch biosorber it is predicted that the biosorbent, CB will require 20% less of the sorbent to treat certain volumes of wastewater containing 500 mg/L of BBG when compared with the unmodified biosorbent (RB).
