The effectiveness of chemicals as coagulants such as alum and ferric chloride is well recognized. However, there are many disadvantages associated with the usage such as high operational costs, detrimental effects on human health, production of large sludge volumes and the fact that it is significantly affect pH of treated water. It is therefore desirable to replace these chemical coagulants with natural-based coagulants such as from fruit peels to counteract the aforementioned drawbacks. Therefore, the aim of this study is to investigate the efficiency of fruits peels as natural coagulants in treating water over the use of alum. In terms of selection of natural coagulants, this study focused on the local waste materials, which are banana peels, orange peels and mango peels. These peels were collected from neighborhood and local stall and market. These peels were prepared by washing, drying, grinding and finally sieving, thus becoming powder of natural coagulants ready to be used. A series of jar test was then performed to determine the effect of individual natural coagulants on the efficiency of turbidity removal and coagulation activity under various operating factors such as type and concentration of solvents, pH and coagulant dosage. From the findings, optimum solvent concentration of 2.0M of sodium hydroxide (NaOH) reacted with mango peels at optimum pH and coagulant dosage of pH 2 and 110 mg/L, respectively showed greatest turbidity removal of 92.7% compared to the other tested natural coagulants including chemical coagulant, which was alum. Therefore, it can be concluded that the natural coagulant in specific mango peels pose a great potential in replacing chemical coagulant for the treatment of water.

“…Fava beans are very low in saturated fat, cholesterol and sodium. They are also a good source of dietary fiber, protein, phosphorus, copper, manganese, and a very good source of Folate [22][23][24][25][26][27]. Fava beans are very high in protein, rich source of dietary fiber,high in phytonutrients such as isoflavone and plant-sterols.…”

The aqueous and ethanolic extract of Passiflora edulis and Vicia faba L. (Fabaceae) exhibited antimicrobial activity against the pathogenic microorganisms: E. coli, S. aureus, K. pneumoniae and C. albicans. This was evaluated using the Disc Diffusion Assay under asceptic conditions. Antimicrobial activity wasn’t induced by the solvent, ethanol nor water. The highest AZOI was 153.9 mm2 and the lowest 12.56 mm2. Negligible Zone of Inhibition, ZOI were observed in several instances. The aqueous extract of the fruit also induced negligible Zone of Inhibition, ZOI. In comparison to the reference, Ampicillin and Nystatin, these values are less. As the concentration of the metal salt, Zn(OAc)2.2H2O and ethanolic extract increases, there seem to be a variation in antimicrobial activity. Zn(OAc)2.2H2O appears to intensify the antimicrobial activity of the plant ethanolic and aqueous extract. Zn (OAc)2.2H2O in the absence of any extracts exhibited antimicrobial activity. The AZOI range from 47.2 mm2 to 117.8 mm2. Antimicrobial selectivity was also observed in several instances.
