Measurement of physical and transport properties of tannery effluent (soak liquor)

Treatment of effluents is a serious issue for present process industries. Several new techniques are being developed which require the knowledge of effluent physical and transport properties for design and development of treatment plants. In this work density, kinematic viscosity, thermal conductivity and specific heat capacity of the tannery effluent (soak liquor) were measured for various salt concentrations of soak liquor ranging from 3% to 20%. A non-linear regression analysis has been carried out using these experimental data and the empirical correlations are presented. © 2007 Elsevier Ltd. All rights reserved.
