Smart Algae Harvester A120

The Smart Algae Harvester A120  is a mid-scale algae harvester that can process up to 120 liters (32 gallons) per minute of algae water and is ideally suited to distributed architectures. Individual A120 units can each be assigned to manage ponds or bioreactors and can be combined to achieve larger parallel processing capability.

Based on our core platform, Electro Water Separation™ (EWS), the A120 is a continuous flow system to efficiently dewater and concentrate microalgae. It can remove up to 99% of the incoming water volume and produce a 5-10% solids concentrate, with accessories available for higher concentrations.

Kills Bacteria to Extend Shelf-Life

The A120 can operate either continuously or intermittently on a wide variety of microalgae strains.

EWS systems have been validated to effectively remove harmful invaders and pathogens such as bacteria, rotifers, ciliates, and protozoa.

EWS has been successfully tested on many algae strains, including Botryococcus braunii, Haematococcus pluvialis, Nannochloropsis sp., Tetraselmis sp., Chlorella sp., Scenedesmus dimorphus and more.

The benefit of this architecture is that, where growth modules are shut down for maintenance or other reasons, the corresponding harvester doesn’t have to be run, which maintains optimum capacity sizing. Additionally, each harvester is a backup for the rest.

“After evaluating OriginOil’s products, our technical team felt that OriginOil had a novel, scalable, and potentially game-changing technology to harvest and process algal biomass into commercially viable products.”

Hugh Morris, COO, AlgEternal

The A120 was designed with producer input for distributed architectures.

Algae for Aquaculture

The A120 design is also ideally sized to harvest algae product for fish feed. It solves the biggest problem in algae production for fish feed, which is how to concentrate the algae so that it can then be pelletized. With the A120, this is simply no longer an issue.

Algae farmed in aquaculture sites can become a substitute for fish meal. The cost of farming algae in most locations would be around $400 to $600 US dollars per metric ton. If compared to the $1700 dollars per ton that fish meal costs, this induces a 60-70% savings in fish meal costs.

“We are very excited about implementing OriginOil’s technology both for treating the water to remove ammonia and bacteria and for harvesting algae for fish feed. The cost of fish feed has tripled over the last decade and is now our highest cost.”

Rocky French, Operations Manager at Aqua Farming Technology, a sustainable fish farm operator near Palm Springs, CA.
