Photocatalysis for Water Treatment

Chinniah V, Prem Anand J and Somasundaram N.

Among other advanced oxidation processes, TiO2 photocatalysis is found to be an easy handling, much more effective and economical method to suit for environmental remediation of organic dyes. To achieve maximum degradation of dyes were found to be at the optimum conditions; initial concentration of dye was 8mg/L, at pH 2.5, photocatalyst dosage was 4 g/L, and irradiation time was 4 h.. The photodegradation dyes such as methyl orange, methylene blue, malachite green, basic fuchsion  and rhodamine B were also tested, and the rate of degradation of dyes were found to reach 85% to 98%. The high reactivity, stability, retention of photocatalytic activity of the catalyst, TiO2 was well observed even after several runs

Fluoride Contamination of Underground Water during Winter Season in Dindigul District, Tamilnadu

Prem Anand J, Ananthanarayanan L and Somasundaram N.

Fluoride is consumed by humans predominantly through drinking water. Eventhough, many reports published in the fluoride area, it is necessary to measure fluoride content time to time in the high risk parts of the country like Dindigul and Dharmapuri districts of Tamilnadu state to adopt remedial measures and creating awareness to the people living in the area. Due to population explosion in the prone places of employment opportunities and outskirts of the cities, particularly the high risk factor of reported fluoride endemic parts should be monitored periodically to understand environmental impact and the changes in physical parameters, chemical and geological aspects. In southern part of India, Dindigul district is found to be one of the high fluorosis affected places. Certain parts of the district were chosen randomly after going through the literature thoroughly as study area in particularly, the winter season. Many changes in the concentration level of fluoride have been expected due to rain water seepage, runoff from agricultural field, dilution of surface water, etc

Knowledge on Export by Orange Growers in Vidarbha

Tekale V.S. and Mano Sandesh V.V

The present study entitled “Knowledge on export by Orange Growers in Vidarbha” was undertaken in Kalmeshwar, Katol and Narkhed talukas of Nagpur district and Warud and Morshi talukas Amravati districts with sample size of the 120 respondent orange growers. Majority of the respondents were belonged to middle age group with education up to higher secondary school level, nearly half of them had farming occupation with a medium family size, belonged to medium land holding with annual income between Rs. 3,00,001 to 4,00,000. Nearly half of the respondents had medium social participation and mass media participation, one by third of the respondents had not received any training and more than two third of respondents had well/ tube well as their source of irrigation. In case of export knowledge majority of the orange growers had medium level of knowledge on export. Whereas, in case of export knowledge components more than half of the orange growers had medium knowledge about export standards and nearly four by fifth of the orange growers had low level of knowledge about export procedures. The export knowledge index shows that majority of the respondents (42.75%) belonged to medium category. In the correlation analysis of export knowledge with independent variables, the variables namely, education, mass media participation and training received bear positive and high significance (significance at 0.01 level of probability). The independent variables like family size and sources of irrigation were non-significantly related with export knowledge

Processing and Analysis on Kombucha (Fermented Sweetened Tea)

Aye Aye Win, Pyie Phyo Maung, Min Min Han,Bo Bo, Hnin Ei Phyu, Zin Min Htwe, Khinthida Phyo, Khaing Zarlinand San Htwe Kyi

Kombucha is a fermented tea liquid and consumed as a sources of antioxidant activity, made from tea leaves, sugar and SCOBY(symbiotic colony of Bacteria and Yeasts).SCOBY was obtained from South Korea and used for the processing of fermented tea (kombucha).Black tea was used generally for making kombucha but other types of tea such as; green tea and yellow tea also used for kombucha making and analyzed and compared the finding results. During fermentation, pH dropped slowing before 14 days and showed below around 2.9, is a good fermentation for consuming kombucha. pH dropped during fermentation because of many organic acid productions during fermentation. In the analysis of sugar contents in kombucha, first high sugar contents were detected and dropped during fermentation period because some yeasts from SCOBY consumed sugar and converted into alcohol and then to some organic acid such as gluconic or glucuronic acid. In Kombucha making, the tea product is used as a raw sources and tea is a rich of polyphenol, thus polyphenol is also included in kombucha. For total polyphenol contents analysis, there is no significant different loss of total polyphenol contents during fermentation. According to the DPPH assay, all kinds of kombucha tea product possessed high antioxidant activity because many polyphenol, high organic acids included in kombucha. There was not found any toxicity after analysis with mices. Therefore, kombucha is a high antioxidant activity liquid beverages and consuming habit may give healthy effects for customers

Effect of Alkalinity on Planktons of Lodha Pond of Banswara District (RAJ)

Pooja Joshi, Lalit Chaudhary, Manish Kunwar Sisodiya and Seema Bharadwaj

The alkalinity of water is its capacity to accept protons it can shift the pH to the alkaline side of neutrality. Alkalinity of natural water is the result of bicarbonates and it usually expressed in the form of calcium carbonate. The aim of this study was to evaluate the effect of alkalinity on planktons of lodha pond of Banswara district. In the present investigation, maximum values of alkalinity during monsoon and winter may be due to household detergents products added in the pond only in monsoon season due to use of bicarbonates by the pond biota directly for their load which leads to the depletion of bicarbonates in water resulting in low values of total alkalinity due to which planktons diversity and its growth getting effected
