By pulsing contaminated water over screens on which algae are allowed to grow, algal turf scrubbers can use sunlight to purify agricultural runoff while yielding byproducts that can be used as fertilizer, biofuel, or higher-value commodities such as nutraceuticals. Hectare-scale demonstration projects are in operation.
