Bioflocculation

Water issue adressed: Too dirty
My study investigated the feasibility of a bio-flocculant as an accessible, safe, affordable and environmentally friendly option to reduce turbidity. Using a combination of dried lemon peel and chitosan, I tested different concentrations to find the optimal dosages to reduce turbidity. The bio-flocculant identified offered an affordable treatment option for those with limited access to clean water while being environmentally friendly and offering no adverse health effects sometimes associated with flocculation. 
This is how I came up with the idea for this project:

After investigating the use of lemon peels for bioplastics, I became interested in applying the properties of lemon peels to water treatment. Growing up by the ocean, I have always had a profound appreciation for water and the precious way in which it sustains life.
