• Microalgae harvesting is a major bottleneck to microalgae-based biofuel production. Flocculation the most versatile, energy-efficient and cost-efficient process. Polyacrylamides exhibit high performance at different operation scales. Comprehensive analysis of polyacrylamide-microalgae flocculation was presented. Properties polyacrylamide microalgae culture influence biomass touted as highly p...

Sea salt is produced from the evaporation of seawater containing harmful microplastics, and this process leads to sea enrichment with microplastics. To solve issue, coagulation method for microplastics removal was studied, Fourier transform infrared spectrometer spectrum adopted analyze amounts MPs in coagulated flocs. AlCl3, Al2(SO4)3, FeCl3, CH3(CH2)3SiCl3, CH3(CH2)7SiCl3 were employed as coa...

In the phosphate industry, thickening process is vital to increasing solid slurry concentration and recovering water that as clear possible. The performance of depends mainly on coagulation–flocculation effect. based flocculant agents concentrate particles: flotation washing plant rejects large flocs, which accelerate their sedimentation velocity. industry worldwide uses synthetical flocculants...

Heavy metal, chromium (VI) removal by coagulation using natural coagulant material was investigated in this paper. Chromium occurs naturally in the paint manufacturing industry waste water in many steps of the process. The coagulation and flocculation method is used for chromium removal from waste water using fruits of Opuntia Ficus indica, Fruits of Jatropha gossypifolia and peel of Borassus f...

Water scarcity encourages researchers to keep working on natural coagulant agents such as Moringa oleifera seed extract, that could be used even in developing countries. With this scope, this investigation is focused on the optimization of certain parameters affecting the use of this coagulant product in the clarification of real surface water. Acidic pH levels seem to enhance the coagulation p...

Moringa oleifera seeds contain about 40% of highly valued oil due to its wide range of applications, from nutritional issues to cosmetics or biodiesel production. The extraction of Moringa oil generates a waste (65%-75% of seeds weight) which contains a water soluble protein able to be used either in drinking water clarification or wastewater treatment. In this paper, the waste of Moringa oleif...

One of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. Not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic life. In the present study, impact of such factors as salinity, pH and DO on flocculation of...
