Abstract: Most of the textile, dyeing and printing industries are creating water pollution by discharging their effluents directly to the nearby water resources. Different methods are in use for removal of these effluents, but these methods are associated with some or the other demerits. Photochemistry may play an important role in solving this problem. Semiconductors are used as photocatalysts for removal of dyes from their solutions. In the present investigation, semiconducting tin sulphide has been used as a photocatalyst for the removal of rose Bengal. Different parameters like pH, concentration of dye, amount of semiconductor and light intensity, which affect the rate of the reaction have been studied. A mechanism has also been proposed.

Keywords: Gas Chlorination, Textile wastewater, Colour removal.
Abstract: Textile industry is the oldest and largest industry. Effluent generated from the industry is in enormous quantity. It contains pH more than 7 due to the addition of caustic soda in the process, high TDS due to the addition of salts for fixation, high COD due to the addition of chemicals and fixing agents, high BOD due to the addittion of dyestuffs. Effluent containing above parameters will be obnoxious, toxic to the water bodies. Before disposal into the water bodies it should be treated. Existing treatments are not adequate to remove the colour and reduction of COD. Also, some treatments require large area, more investment of money and generation of sludge, which is a major problem for disposal. Hence, the textile industries in Erode have adopted the treatment by the gas Chlorine. The rate of reaction for Chlorine with textile dye effluent on colour removal was bahaved in first order with regression coefficient ranged from 0.83 to 0.999 and kinetic rate constant ranged from 0.081/min to 0.721/min. The percentage of colour removal was 41 to 95. The percentage of COD degradation was 22 to 58.

Abstract: Stringent regulations are made for the removal of heavy metal ions from water and wastewaters prior to discharge into water bodies. Fly ash, generated during the combustion of coal for energy production, is an industrial by-product which is recognized as an environmental pollutant. The equilibrium uptake of various metals from wastewater pathways through sorption under operating conditions including pH, equilibrium time, metal concentration and biosorbent loading is considered by several researchers. Langmuir and Freundlich models are generally used for fitting sorption data. Fly ash can also effectively remove metals from multi-metal solutions. This paper reviews the art in the field of biosorption by application of fly ash as biosorbent.

Abstract: In the present study, Magnesium Chloride and Gulmohar Plant (Delorix Regia) leaf powder was used as adsorbent for the removal of different types of synthetic dyes (viz. Methylene Blue, Procion Brill Blue and Eriochrome Black-T) from aqueous solution in order to identify its ability to remove colour from waste water by adsorption. The colour removal efficiency for the synthetic dye solutions was compared using two adsorbents through two experimental parameters such as effect of adsorbent dosage and pH by conducting batch experiments as these are the two main parameters which determine maximum colour removal. The effect of adsorption of Magnesium Chloride with addition of equal dosage of coagulant Calcium Hydroxide was studied. It was observed from the studies that the adsorption of dyes is a gradual process and a greater percentage of dye can be removed with biodegradable Gulmohar Plant leaf powder at higher dosage than with Magnesium Chloride under favourable condition for all dyestuffs tested. The Gulmohar Plant leaf powder is more economical and ecofriendly as there is no sludge production in the treatment process.

Abstract: When an existing building is demolished the debris is dumped in unused lands, particularly in the outskirts of the city. For any growing town or city, managing the building debris is a problem. It is mostly not reused or is used as a filling material in some areas. To avoid this problem existing structures can be strengthened. Columns are one of the main components of the structures. Substantial progress has been made over the past decades in the use of composites in the construction industries, which includes the use of confinement like PVC, FRP, STEEL, AC PIPE, and WELD MESHES etc. It reduces the problem associated with deterioration of the infrastructures. The confinement should be adequate to develop the flexural hinges and to provide sufficient ductility. This paper presents the results of a study on the axial compressive strength of columns strengthened with PVC wrap. The experimental part of the study included testing six reinforced concrete columns in three series. The first series comprised two similar circular plain concrete columns strengthened with PVC wrap. The second series consisted of two similar circular columns with nominal reinforcement strengthened with PVC wrap. The third series comprised two similar circular RCC columns confined with one layer of chicken mesh and one layer of weld mesh and outer confined with PVC wrap. Axial compressive load was applied to the specimen by UTM in predetermined increments of loads up to failure of the specimen. The ultimate crushing strength was noted for each specimen and the results are compared with that of the control specimen. According to the test results, the PVC wrap increases the strength of circular columns. The conventional RCC column when subjected to direct compression may not reach its ultimate load carrying capacity because of the premature buckling. This experimental study shows clearly that when the conventional concrete is confined by an external confinement, the load carrying capacity is considerably increased.
