Title: Algal harvesting and water filtration

Abstract

Systems for algae-based water filtration and algae harvesting are described herein. A flow-way comprises a channel and a divider positioned within the channel that separates the channel into sub-channels. The flow-way further includes an algal growth that grows on a sidewall of the channel and/or the divider. The algal growth can be established in the flow-way by positioning a pre-seeded mesh element within the channel, the pre-seeded mesh element having an algae culture growing thereon prior to positioning the pre-seeded mesh within the channel. A harvesting system comprises a hinged container that includes a straining screen. The hinged container is positioned downstream from a flow-way and receives water from the flow-way. Biomass in the water is strained by and accumulates on the screen. Weight of the accumulated biomass causes the hinged container to tip and deposit the accumulated biomass in a second container.
