Potential Applications of Natural Coagulants in Portable Filtration Device for Flood Zone Residents

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 standard provision water. DFBE ASE as coagulation aides improves efficacy alum high turbid (150 175 NTU) low (20 30 NTU). ratio Alum was determined be 1/6 high-turbidity 0.2 low-turbidity DFBE/Alum greater than 1/3 turbidity less This also evaluated portable, simple, user-friendly filter suitable flood-prone residents. Combining with satisfies sources turbidity. demonstrates utility aids derived from residues purification flooded areas.
