Centrifugation device and methods for isolation of biomass from algae mixture and extraction of oil from kitchen residue

摘要

A centrifugation device includes a feeding tube defining a longitudinal axis, and a plurality of centrifugal plates extending longitudinally and radially around the feeding tube and rotatable about the longitudinal axis. The centrifugal plates have coarse surfaces coated with one or more layers of polymer material. A centrifugation tank is disposed coaxially with the feeding tube and around the centrifugal plates. A sidewall of the tank is provided with micro/nano filters. Methods for isolation of algal biomass from an algae and aqueous mixture, and extraction of oil from kitchen residue and/or microalgae are also disclosed.
