Organic tofu using organic compatible coagulants of magnesium chloride and three polysaccharides including carrageenan, guar gum and gum Arabic were generated. For MgCl2 coagulated tofu, carrageenan significantly increased the hardness from 969.5 g to 1210.5 g whereas guar gum (0.6g) decreased the hardness to 505.5 g. Interestingly, gypsum and guar gum (0.6g) increased the yield of tofu signifi...

Water treatment (WT) is currently among the major areas of research due to depletion water resources and fearmongering regarding environmental pollution, which has compelled upgrading conventional WT technology towards recycling reuse. This review aims provide current state natural coagulants their application in purification surface as sufficient clean required for household needs, health secu...

Drinking water for residents who live in flood area is the concern of government and environmental management. Using natural coagulants to transform into potable order reduce number chemical (aluminum salt) that have a negative impact on human health. The results flocculation procedure using agricultural residue extracts, dragon fruit branches (DFBE) avocado seeds (ASE), did not meet Vietnamese...

In the present study, several pre-polymerized coagulants of iron and aluminum were tested for their efficiency towards As(V) and As(III) removal from water sources. The results showed that the pre-polymerized coagulants of iron, such as poly-ferric sulfate and poly-ferric silicate chloride, were very efficient for As(V) removal. With regard to As(III) removal, among all examined coagulants, inc...

Aluminium and ferric salts are widely used as coagulants in water and wastewater treatment. They are effective in removing a broad range of impurities from water, including colloidal particles and dissolved organic substances. Their mode of action is broadly understood in terms of essentially two mechanisms: charge neutralization of negatively charged colloids by cationic hydrolysis products an...
