Abstract

Abstract:Duringprocessing and disposal of solid waste, there is production of odorous gaseswhich is one of the major issue faced in Solid Waste Management. There are threatto not only living animals but also the landmass facility as well as naturalflora and fauna. Major gases responsible for causing odour from a solid wasteare hydrogen sulphide and ammonia. A study has been performed on municipal,commercial and institutional solid waste for the decreasing rate of productionof odorous gases when they are microbially treated using Biowish technology.Two gases are chosen for analysis which is ammonia (NH₃) andhydrogen sulphide (H₂S). Emission concentrations of these gases weremeasured initially at different temperatures ranging from 28±2⁰C to 36±2⁰Cwithout applying Biowish chemical. Later, Biowish chemical was sprinkled onthose solid wastes by dissolving in water at different concentrations andconcentration of ammonia and hydrogen sulphide measured. Analysis shows thatthere was considerable reduction in strength of ammonia and hydrogen sulphidewhen Biowish chemical was applied in higher doses and at higher temperature. Insome cases it was reduced to even zero also.
