Abstract

Discharge of textile and industrial waste water to surface or ground water is very dangerous. Therefore treatment of any kind of waste water to discharge effluent with good quality is mandatory. Preventing solids deposition is a constant challenge in wastewater treatment. Minimizing particle settlement and subsequent sediment buildup requires strong bulk flow. The Jet Mixing concept was developed in response to problems documented in efficiency of mixing in circular or rectangular tanks Jet mixers in wastewater treatment applications primarily in unit processes where liquid blending, solids suspension, flow generation or chemical reactions are key process parameters. Jet mixers are ideal for these types of applications. The main objective of the present study is to determine the critical velocity of solid suspension by varying the nozzle diameter, nozzle clearance, solid (sand) size and composition. Experimental results show that the fractional hold up increases with increase in jet velocity. The optimum nozzle diameter is found to be the nozzle having 10mm diameter, located at 30 cm above the base of the mixing tank .The optimum nozzle design is not universal, and varies with the geometry of system. Correlation for fractional hold up has been developed. Application of jet mixer design for waste water treatment is highlighted.
