background; water treatment sometimes needs a coagulation and flocculation process to remove suspended and colloidal materials. inorganic coagulants used create concerns about pollution of the environment and harmful effects on the human’s health. the studies carried out previously indicated the capability of an active coagulant agent extracted from descurainia sophia seed to remove turbidity o...

Abstract Coagulation and flocculation provide a rather straightforward method towards water clarification. However, ongoing debates over worrying health issues linked to chemical coagulants have paved the way to develop plantbased natural coagulants. Natural coagulants are not only water clarifying agents, but they also have antimicrobial and heavy metal removal properties in some instances. Th...

Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers and scientists. Resource-efficient and environment-friendly solutions to this hazard are a call of the hour. Coagulation, by synthetic chemicals, has been used as a cost-effective and efficient method for manag...

Turbidity imparts a great problem in water treatment. Moringa oleifera, Cicer arietinum, and Dolichos lablab were used as locally available natural coagulants in this study to reduce turbidity of synthetic water. The tests were carried out, using artificial turbid water with conventional jar test apparatus. Optimum mixing intensity and duration were determined. After dosing water-soluble extrac...

A review of plant-based coagulant sources, processes, effectiveness and relevant coagulating mechanisms for treatment of water and wastewater is presented. These coagulants are, in general, used as point-of-use technology in less-developed communities since they are relatively cost-effective compared to chemical coagulants, can be easily processed in usable form and biodegradable. These natural...

In water scarce countries such as Eritrea, maintaining brewery industry remain ever challenging task. Currently, Asmara breweries is the only beer producing factory consuming 8.46 L of per every produced which notably higher than Brewer’s Association (BA) benchmark and consequently generates 7.53 wastewater/L beer. Bottle cleaning activities ascertain ample effluent bases. Wastewater from bottl...

<p>Growing environmental awareness coupled with stricter regulations has pushed various industries to look for appropriate technologies treat wastewater. Natural coagulants have recently been used as part of water and wastewater due their performance, cost-effectiveness when compared chemical coagulants, they produce less sludge are safer humans. A huge effort also taken find new plant sp...
