This research deals with the highly available sugar industry waste material, press mud as low cost biosorbent for the removal of textile dyestuff from aqueous medium, and the investigation of the probably involved physiochemical mechanisms. Experiments were carried out in batch reactor. The results of equilibrium studies showed that equilibrium state was reached within 48 h of exposure time and maximum biosorption taken place at the biosorbent dosage of 30 mg/ml of solution. Secondly, several biosorption kinetic models were applied to fit the experimental data, namely Lagergren irreversible first-order, Reversible first-order, Pseudo-second-order, Elovich and intraparticle diffusion models. The proposed explanations were deduced from the theoretical assumptions behind the most appropriate model(s), which could satisfactorily describe the present biosorption phenomenon. The interpretation of the related results have shown that, with R2 of about 99%, the pseudo-second order model is the most suitable dynamic theory describing the biosorption of dye onto press mud predicting therefore a chemisorption process.Keywords

The aim of the paper is to design and develop a dual side water pumping system using scotch yoke mechanism. The reciprocating motion of the plunger is utilized for the pumping action. The plunger is reciprocated with the help of a cam plate. By this action the water is pumped with very high pressure and to various heads. This can be utilized for various applications like lubrication in machines and water pumping in agriculture field. The cam plate gets the drive from the motor for its rotation and converts that rotary motion to useful dual side reciprocating motion. The motor is powered with the aid of electric power. Thus the water is pumped from source to various heads.Keywords
