Abstract

Laboratory studies were conducted to know about the effect of pH of sodium hydroxide solution and its temperature for absorption of SO₂ contained in flue gases. it was found that the pH of the solution should be alkaline for good absorption of SO₂. Because of the acidic nature of SO₂, the reaction is restricted in acidic solution. and maximum absorption of SO₂ was found in temperature range between 20-25°C. At higher temperature reversible reaction may take place and partially formed product may be changed back into initial reactants.

Abstract

Human activity generates considerable amount of solid waste. The nature of waste varies depending upon the kind of activity. Municipal and biomedical wastes are the major solid wastes contributed from the urban centre, Ajmer. Ajmer has Dargah of Khwaja Mounuddin Chishty, a pilgrimage centre for muslims of the world, and Pushkar pilgrimage for the Hindus of the world. The study was carried out to understand the present status of solid waste management of the city. The total quantity of solid waste generated in the city is around 950 TPD (tons per day) with a per capita generation of 0.35 kg. Sporadic incineration is very common and no proper disposal facility has been provided for the municipal solid waste.

Abstract

Rain water samples were collected at roof level at Pushkar and Budha Pushkar during July, 2007. Water samples were also collected from 2 ponds around in Ajmer district. Physico-chemical and bacteriological parameters were analysed. Roof water was found to be pure and free from bacteriological contamination. Pond water is turbid and has high iron content with objectionable bacteriological pollution load. collection of roof water for drinking purpose was found to be encouraging. Pond water needs treatment before use.
