Smart Algae Harvester A25

Introducing the new Smart Algae Harvester™ A25. Using OriginOil’s Electro Water Separation™ (EWS) water cleanup technology, The Smart Algae Harvester A25 solves a major obstacle to practical algae production: how to efficiently remove low density algae cells from large amounts of water.

The system combines electrochemical processing and state-of-the-art controls to enable a flow-through, continuously harvesting process. By adjusting the process conditions in response to the conditions of the feed water, the Smart Algae Harvester ensures efficiency and a high quality product.

Purchasing and Licensing available. You can purchase Smart Algae Harvester from OriginOil or one of its distributors, or license the technology as an OriginOil Equipment Manufacturer.

A Harvesting Workhorse

The Smart Algae Harvester A25 is available for commercial production and can also serve as an important R&D tool.

The A25 is rated at a nominal 25 liters (6.5 gallons) per minute of raw algae water in any concentration up to ~3 g/L dry weight.

The A25 can remove up to 99% of the incoming water volume and produce a 5-10% concentrate (higher concentrations available with downstream devices).

Cost-Efficient and Continuous

Based on our core platform, Electro Water Separation™ (EWS), the A25 utilizes a continuous flow system to efficiently dewater and concentrate the microalgae, with a power consumption of approximately 0.7kWh per incoming m3.

The A25 will operate either continuously or intermittently for testing purposes on a wide variety of microalgae strains.

We have successfully tested process on numerous algae species, including Botryococcus brauneii, Haematococcus pluvialis, Nannochloropsis sp., Tetraselmis sp., Chlorella sp., and Scenedesmus dimorphus.

The system has been shown to effectively remove harmful invaders and pathogens such as bacteria, rotifers, ciliates, protozoa, amoeba and parasites.

Touchscreen Operation

Using the touchscreen-operated intelligent power management system, operators can take readings via sensors and control parameters such as flow rate or pH to better manage and dispense energy to achieve optimum algal harvest.

The system can connect through wireless sensor networks to central management facilities, thus enabling commercial farmers to monitor and manage an entire array of harvesters at full scale, up to hundreds of acres.
