We plan to separate active carbon into many layers, we can then collect water from the SST Eco-pond. We will pour the water through the different layers of filters of active carbon to filter them. We plan to use a turbidity sensor to find out the turbidity of the water after coming through the different layers of filters. We will see the effect of the active carbon on the water turbidity and the relationship between them.We will then decide if the water is of safe turbidity according to the World Health Organisation(W.H.O) standards. We will then find out how many layers of activated carbon produces the safest water in terms of its turbidity.
