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...

Sulphated polysaccharides with anti-thrombotic and anti-coagulant activities have been found in various marine biota. In this study, a previously characterised anti-thrombotic and anti-coagulant extract from blacklip abalone was fractionated by anion exchange chromatography (AEC), pooled (on a sulphated polysaccharide basis) and administered to Wistar rats via oral gavage (N = 8) for assessment...

potassium ferrate has been used as a multi-purpose chemical in treatment of wastewaters. with the formula of k2fe04 it has 3 excellent characters for water treatment, so by using it alone, it would be possible to confine all reactivity, it is essential to prepare ferrate at the point of use. in this study, k2fe04 was synthesized, then it has been employed for chlorine gas with an alkaline solut...

in this study, ultrafiltrated feta cheese was prepared from cow’s milk ultrafiltraton retentate and soymilk blend. rennet and calcium chloride were used simultaneously as coagulant to coagulate cow’s milk proteins and soymilk proteins, respectively. then, the effect of storage period on physical (texture profile analysis test, penetration test), chemical (total solids, protein, fat) and sensory...

• UF coagulant dose controller was successfully developed and field tested. • Self-adaptive in-line UF coagulant dosing reduced coagulant consumption. • Real-time tracking of fouling resistance and backwash effectiveness. • Robust UF operation during conditions of deteriorating source water quality. ⁎ Corresponding authors.

The ability of a commercial tannin-based coagulant on the decolorization simulated textile effluent containing reactive dye was studied in batch mode. For comparison, two conventional chemical coagulants (aluminum sulfate and Rifloc 6548-organic coagulant) were also tested. Preliminary assays suggested higher performance Tanfloc SG over metal salt. Optimization conducted for SG, indicated maxim...

Coagulants can be extracted from vegetal material and applied in the treatment of wastewater. These coagulants are derived seeds, leaves, bark, roots fruits. This study focuses on use mucilaginous extract Stenocereus griseus (known as Cardón Guajiro) for removal biochemical oxygen demand (BOD5), chemical (COD), total solids, turbidity color domestic wastewater a pumping station city Cartagena (...

Microplastics have been detected all around the globe in freshwaters which are frequently used to produce drinking water. Therefore, contamination of raw water with microplastics that supplies treatment plants, and their removal efficiency is raising more concern interest. In present study, we evaluated microplastic a conventional plant (Geneva, Switzerland) contribution coagulation on filtrati...

heavily polluted wastewater from sanitary landfill presents the leachate characteristics that need special treatment and disposal. concentration of chemical oxygen demand (cod), ammonia nitrogen (nh3-n), heavy metal and other pollutant content are often larger than standard requirement after applying biological/physico-chemical treatment.thus, the combination of coagulationflocculation and chem...
