Effective management of intricate oily wastewater presents a formidable challenge. While diverse methods like gravity separation, centrifugation, and membrane techniques are employed for oil-water separation, gravity separation is the prevailing choice, yet limited to unstable emulsions. These methods often involve toxic substances harmful to marine life. Our research focuses on separating oil microemulsions in aqueous solutions. This study explores the application of superparamagnetic chitosan coagulants, revealing an optimal 10 ml dosage for peak efficiency. Aiming for rapid oil separation, we achieved a breakthrough with just 30 minutes, establishing a new benchmark. Rigorous VSM testing solidified the particles' magnetic capabilities, augmented through size reduction. Notably, at a 15% oil concentration, a r...

Effects of different properties viz. grain volume, surface area, sphericity, bulk density, true density, porosity etc. on moisture content are studied. These properties of wheat which affect the flow characteristics of the samples in a fluidized bed dryer are found to be dependent on moisture content of samples. Thus the drying of wheat is found to be dependent on its physical properties.

Although the literature has identified several quenching methods, including upward-facing spray, downward-facing spray, and both-sides spray, upward-facing spray cooling is the most efficient. The coolant's thermophysical properties may improve upward-facing spray cooling. Thus, upward-facing spray cooling was used in this study to augment the heat transfer with better fluid properties. This study uses ethanol-added water as a coolant and heat transfer analysis to boost heat removal. The statistical analysis software (Designexpert@7.0) models an upward-facing spray and finds that for maximum heat removal the Weber and Reynolds numbers must be 700 and 2220, respectively. Fluid properties are viscosity 8660 × 10-7 mPa s, density 997.7 kg/m3, and surface tension 54 mN/m. Theoretical studies and dropwise experiments were used to determine the upward-facing spray augmentation mechanism. The comparative analysis shows that ethanol is less corrosive than the additives reported in the literature. After experimentation, the total dissolved solid concentration in used water exceeds the permissible limit.

Based on the literature, modelling of a bed dryer is carried out for two situations: for spherical and non-spherical particles. Two case studies were taken from the literature for modelling the fluidized bed dryer for naphthalene balls and mushroom slices. Fluidized bed dryer design was carried out with respect to diffusivity of the bed materials. Drying characteristics in terms of effective diffusivity were studied for naphthalene balls and mushroom slices using a tapered fluidized bed dryer. The variation of effective diffusivity was obtained with change in inlet air temperature, velocity, thickness of slab and drying time. Experimental effective diffusivity as obtained from literature was compared with model predicted values, provided lower deviations with RMSE of less than 8.28% for spherical naphthalene balls and 0.936% for the mushroom slices. Mass transfer coefficient obtained for naphthalene balls was in the range of 2.1×10−4 to 4.857×10−3m sec−1. The diffusivity constant was evaluated using Fick’s diffusion equation assuming surface moisture in equilibrium with the surrounding atmosphere. The value of diffusivity constant (D0) obtained is 1.828×10−9 m2sec−1 and the value of activation energy (Ea) obtained is 4.523 kJ mol−1.
