A study was performed to investigate the impact of turbulent heterogeneity on aggregation and breakup in a flocculation reactor. The influence of the average characteristic velocity gradient (G), particle concentration, and coagulation mechanism on the flocculation performance was also investigated. Experiments were performed in a bench-scale reactor with a low-shear axial-flow impeller using a...

Although superfine powdered activated carbon has excellent adsorption properties, it is not used in conventional water treatment processes comprising coagulation–flocculation, sedimentation, and sand filtration (CSF) due to concerns about its residual treated water. Here, we examined the production fate of very fine particles with lacking charge neutralization as a source filtrate after CSF tre...

There is no access to basic sanitation for half the world's population, leading Socioeconomic issues, such as scarcity of drinking water and spread diseases. In this way, it vital importance develop management technologies relevant target population. addition, in separation form treatment, compound often used a coagulant treatment aluminum sulfate, which provides good results raw turbidity colo...

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...

The operation of a health care facility, such as a cholera or Ebola treatment center in an emergency setting, results in the production of pathogen-laden wastewaters that may potentially lead to onward transmission of the disease. The research presented here evaluated the design and operation of a novel treatment system, successfully used by Médecins Sans Frontières in Haiti to disinfect CTC wa...

Abstract This research is centered on the optimization of coagulation–flocculation treatment cosmetic wastewater. It analyzes blends fishbone (BFB) and aluminum-based coagulant (ABC) to determine efficacy BFB as a potential coagulant–flocculants aid at optimum conditions using response surface methodology (RSM). The experiment was carried out employing standard nephelometric procedure 1000 rpm ...

Coagulation and flocculation are traditional methods for the treatment of polluted water. Electrocoagulation presents a robust novel and innovative alternative in which a sacrificial metal anode doses water electrochemically. This has the major advantage of providing active cations required for coagulation, without increasing the salinity of the water. Electrocoagulation is a complex process wi...
