Abstract

See full text

A method and system removes biological contaminants from an algal crop. A flow of an algal crop containing biological contaminants is provided to a hydrodynamic separator (HDS) system. The flow is controlled by a control mechanism, wherein the biological contaminants are concentrated into a first portion of the flow of the algal crop within the HDS system, based on the size of the biological contaminants, and the first portion contains a majority of the biological contaminants in the flow of the algal crop. A second portion of the flow contains a majority of algal in the flow of the algal crop. The flow of the algal crop is split by use of a bi-furcated output of the HDS system. The splitting is between the first portion containing the majority of the biological contaminants in the flow of the algal crop, and the second portion which contains the majority of the algal of the algal crop. The first portion of the flow of the algal crop containing the majority of the biological contaminants is output from a first output of the bi-furcated output, and the second portion of the flow of the algal crop containing the majority of the algal of the algal crop is output from a second output of the bi-furcated output.
