Point-of-use upflow sand filter for rural water treatment using natural local sand: Understanding and predicting pressure drop
A simple, small scale upflow sand filter was fabricated using a locally obtained sands at three different rivers in Sabah, Malaysia: Liwagu River (SL), Tamparuli River (ST), and Kaingaran River (SK). The grain size, porosity, bulk density, particle density and sphericity of the sands were characteri...
