The purpose of the flocculation operation is not only to remove substance causing turbidity, but also give particles with ability be trapped in subsequent operations. This paper discusses process generating floc, sedimentation characteristics, separation effect and so on, when macromolecule heavy metal flocculant CSAX used water treatment, especially for ions turbidity coexisting system. resear...

Sludge generated in wastewater treatment processes must be treated an adequate manner, and therefore disposed of environmentally friendly manner. The biggest obstacle to the efficient use sludge is high water content, development methods accelerate dewatering process particularly important. For purposes research, waste created purifying ammoniaphenol GIKIL factory was used. conditioning perform...

Response surface methodology was used with four factors to screen for the best starch and optimize the use of chemicals in order to maximize precipitated calcium carbonate (PCC) filler retention in a peroxidebleached TMP suspension. Three commercial starches were used in conjunction with colloidal silica and flocculant. The PCC loading level and the interactions between PCC level, starch, flocc...

Three commercial starches were evaluated in conjunction with colloidal silica and flocculant to retain precipitated calcium carbonate (PCC) filler. A unique feature of this study was the fact that the filler was pre-flocculated by a portion of starch (2kg starch/t PCC) and the rest of the starch was added after the flocculant but before the silica. The pulp used was peroxide bleached thermo-mec...

In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in which the solid-suspended particles are removed from the liquid. In the present work, the effect...

The efficiency of treatment of synthetic and semi-synthetic waste oil-in-water (O/W) emulsions by vacuum evaporation is evaluated. A previous destabilisation/centrifugation stage increases the quality of the final aqueous effluent. However, proper selection of a coagulant salt or flocculant is required. A comparison of laboratory-scale evaporation results and those obtained in an industrial eva...
