Activity It was a real pleasure and a great honor for me to receive the award "Jacopetti" , on 24th September at Rotary club Naples, for the best Master. Sand filters usually are used as the second step in wastewater treatment after solids in raw wastewater have been separated out in a septic tank, aerobic unit, or other sedimentation process. unit operations in a tabular format, while the PFD is a graphical representation of the flowsheet. Although the comparison will be primarily qualitative at this stage, it should be helpful in providing a deeper insight into the strengths and weaknesses of each process. Recirculation systems use less water and cleaning detergents but require greater capital outlay and in some circumstances may be unsuitable due to cross contamination from one process to another. Students also learn the theory and practice of various unit processes including disinfection, oxidation, coagulation, sedimentation, filtration, adsorption, gas. It is important to be accurate when calculating dosages as too little or too much chemical may be ineffective and too much chemical is a waste of money or even dangerous. In addition, natural impurities such as waxes, proteins and pigment, and other impurities used in processing such as spinning oils, sizing chemicals and oil stains present in cotton textiles, are removed during desizing, scouring and bleaching operations.
