Abstract:
DEFINITION OF THE THEME
The idea of finding solutions to treat toxic wastewater into clean water, raising water-saving awareness to avoid waste and conserve water sources to provide clean water for people. "USE GARBAGE FOR HANDLING GARBAGE"
Vietnam currently ranks 14th in the area of sugarcane cultivation, so agricultural waste is a huge waste of sugar cane waste. Bagasse has a high content of cellulose (45-55%), using bagasse derived from nature, safe, environmentally friendly. This is a new research direction to create the optimal solution, economic efficiency and towards sustainability in the current problem of wastewater treatment.
RESEARCH QUESTIONS
Can we take advantage of agricultural waste to create useful materials to treat waste water?
METHODOLOGY
REMOVE CELLULOSE FROM THE BAGASSE
Pure cellulose
Method: FT-IR, NMR,... spectrum
SYNTHETIC CELLULOSE ACETATE FROM CELLULOSE BAGASSE
3 -OH groups in cellulose are acetylated, CA is durable with heat.
Method: FT-IR, XRD,… spectrum
MAKE UP UP MnO2
The MnO2 has nano-sized pores.
Method: XRD, SEM,... image and spectrum
SYNTHETIC MnO2/CA 6%
MnO2/CA 6% nano-sized, possible good re-adsorption capacity.
Method: XRD, SEM,... spectrum and image
DESIGN OF THE MNO2/CA NANO FILTER EQUIPMENT SYSTEM
Take nano-filtration membrane into the column filter.
Fabricate nano-filter membrane equipment system.
Water quality according to Viet Nam standards are within permitted limit.
SCIENTIFIC CONCLUSION
Successfully synthesized the materials MnO2/CA nano-filtration membrane and designed fabricate nano-filter membrane equipment system.
Affirming the use of the MnO2/CA nano-filter membrane from bagasse to treat wastewater able to spread in the community, bringing both economic efficiency and practical aspects.
