Phenolic compounds are the major source of colour in sugar mill effluent. Details mechanism diffusional resistances for removal phenolic namely: phenol, 2-4 dichlrophenol and dinitrophenol by adsorption onto activated carbon rice husk (ACRH) was studied. The studied based on three resistance models: external mass transfer, intraparticle diffusion twin transfer. relationship transfer coefficient...

In this work, the effectiveness of removing colour and total suspended solid (TSS) from complex organic particulate artificial sewage (COPAS) via coagulation process was studied. Organo-floc (OF), a tannin-based coagulant derived plant used as coagulant. OF applied in jar test experiment at various dosages 57 rpm for 5 min, 30 min sedimentation time to find out optimum dosage TSS removal. Zeta ...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...
