Hey! I am Amanda Ribeiro Machado from Brazil! I live in the south of Brazil, in a city called Osório. I’ve been doing science projects since I was 13 and it’s my great passion. I love science and I love discovering and learning new things.
Tell us what the water concern in your country is!The big water concern in Brazil is the lack of access to clean water for some people and the droughts. The Brazilian population is more than two hundred million people, but only thity five milion people have the access to clean water.
This is what I think is one of the solutions for a sustainable future:I think that one of the solutions for a sustainable future is encourage and invest in the science , because with this we can make a better future. The science bring solutions and especially, sustainable solutions to these concern. In my project I used biomembranes to the textile effluent treatment, with this we can treat the water without damage to the environment.
BIOGRAPE: INNOVATION FOR TEXTILE EFFLUENT TREATMENT USING BACTERIAL CELLULOSE FROM WINE RESIDUE
The project goal was the development of a sustainable alternative to textile effluent treatment, through biomembranes produced with wine by-products. The biomembranes were produced in a static fermentation for 14 days. The biomembranes were tested as adsorbent material to remove the indigo carmine dye in three different concentrations (5 mg/L, 15 mg/L, and 50 mg/L). Removal of 50%, 80%, and 80%, respectively, was observed in the three concentrations. Two industrial textile effluents were tested: green and red. The alternative treatment removed 50% of green effluent and 30% of red effluent. This project has social, environmental, and scientific relevance in developing a sustainable alternative for textile effluent treatment, addressing 8 of the 17 SDSs.
