Abstract: This paper aims to provide a comprehensive tool for evaluating the curing process of felt reinforced polyester resin composites used in the Cured In Place Pipe (CIPP) renovation techniques. During in-situ construction and renovation of pipelines, working time and temperature are important to precisely control the CIPP process. In this study the amount of catalyst used was varied in the range of 2-4%. The viscoelastic properties of the formulations were then investigated with the aid of Dynamic Mechanical Analyser (DMA) in the penetration mode. The results gave a full analysis of the curing process by providing measurements of different parameters including working time, gelation, vitrification and glass transition temperature of the resin-felt composite system. To clarify the thermal properties of the resin system a comprehensive profile of time temperature transformation (TTT) has been constructed for the different amount of catalyst used. The main purpose of the TTT profile was to de

Abstract: Release of coloured textile effluent in to aquatic environment is detrimental as they prevent penetration of light in to water, thereby affecting aquatic life and creates harmful water. Biosorption is an alternative treatment available other than physicochemical and biological methods to treat these toxic effluents. This study investigates the potential of water hyacinths to adsorb hazardous azo dye metanil yellow from aqueous solution. Metanil Yellow, is a widely used toxic dye containing one or more azo bonds (-N=N-). Metanil Yellow is used in number of industries such as textile, dyeing, food, cosmetics, paper printing industries and with textile industries as large consumers. Biosorption process was carried out using immobilized dead aquatic weeds. The influences of adsorption parameters such as initial dye concentration, pH, contact time, adsorbent dosage, agitation speed, and temperature were evaluated and optimized. Further the mechanism of biosorption earned good fits for Langm
