Abstract: Continuous solid-liquid separation, by vacuum or pressure, are integral components of a processing scheme to produce energy from algae, biomass or other types of slurries. In solid-liquid separation systems, there are a wide variety of parameters that influence their performance. These include, for example, particle size and shape, type of particle (i.e. soft, gelatinous, discrete), density, concentration of solids in the slurry, viscosity, cake height, pressure or vacuum, and filter media. Continuous vacuum belt filters and continuous rotary pressure filters have been used to dewater these types of slurries. This presentation will focus on dewatering unit operations, test data and field installations.
