The purpose of this work is the study ability plant material Aloe vera to act as natural coagulant using raw water obtained from a drinking treatment (Mila, Algeria). Different solvents such as: NaCl; NaOH and HCl were used chemical activators extract active components plant, different coagulation-flocculation experiments conducted in jar test apparatus evaluate performance extracted coagulant....

Introduction: Colloidal materials and suspended solids cause turbidity in water. To remove turbidity, clarification method is used that includes processes of coagulation, flocculation, and sedimentation. Due to the long duration of coagulation process, coagulant aids are applied. Despite the favorable efficiency of synthetic polyelectrolytes as a coagulant aid, due to their harmful effects on h...

Background: Turbidity removal using inorganic coagulants such as iron and aluminum salts in water treatment processes causes environmental and human health concern. Historically, the use of natural coagulant to purify turbid water has been practiced for a long time. Recent research indicates that Descurainia Sophia seed can be effectively used as a natural coagulant to remove water turbidity. ...

Olive oil production is one of the important industrial sectors within agro-food framework Mediterranean region, economically to people working in this sector, although there also a threat environment due residues. The main wastes olive extraction process are mill wastewater (OMW) and husks which require proper treatment before dismissal. In research work, goal introduce grey relational analysi...

during estuarine mixing of fresh water with saline water and due to the flocculation process, aportion of dissolved metals come into particulate phase, and the dissolved load decreases. this process plays an important role in self-purification of heavy metals in rivers. in this study, flocculation of cu, mn, ni, pb and zn during mixing of cheshme-kileh river water with caspian sea water has bee...

Biomass harvesting is a bottleneck in microalgae culture and microalgae-based wastewater treatment systems. Sedimentation coupled to coagulation flocculation has been experimentally studied for long time, however, full scale sedimentation experiences have not addressed so far literature, scaling up from experimental results may be straightforward. The aim of this study was evaluate the performa...
