The Algae Appliance™ is our standardized product line, providing a low energy, chemical-free, continuous flow ‘wet harvest’ system to efficiently dewater, rupture cell walls, and concentrate the microscopic algae harvest.

All Algae Appliances use our Single Step Extraction™ technology for a chemical-free, low- energy and high continuous flow harvest at very low capital and operating costs.

If you are interested in evaluating OriginOil’s harvesting technology, then our Model 4 is perfect for your needs.

Process Overview

The Algae Appliance is typically located on premises at the algae growth facility.

When ready for harvesting, the dilute microalgae culture is fed directly from the growth systems into the Algae Appliance without any prior pretreatment or concentration. Each system is equipped with its own integrated control system that manages the operational settings for flocculating (clumping) and for “lysing” of algae cell walls (cell wall rupture).

As the raw algae passes through the Algae Appliance, it is subjected to tuned electromagnetic pulses. The system operation consists of three phases:

• First phase: high-flow, low-energy, chemical-free flocculation.
• Second phase: cell wall rupture for downstream applications where appropriate.
• Third phase: concentration to remove up to 90% of the water.

(Optional devices are available to achieve higher solids concentration downstream from the Algae Appliance.)

Capacity Ratings

Algae Appliance Models are rated by their maximum capacity to process algae dilute continuously, shown in liters per minute.

So for example, the Algae Appliance Model 285 is rated for continuous processing of up to 285 liters per minute (or about 75 gallons per minute) of your algae harvest.

Algae Appliance Model 4

Announced in spring 2012, the Model 4 is an entry-level, low-cost algae harvester designed to make it easier, faster and cheaper for producers and researchers to try and buy OriginOil’s proprietary harvesting technology.

Designated the Algae Appliance™ Model 4 for its rated capacity of four liters (about a gallon) per minute, the new unit will operate either continuously or intermittently for testing purposes on a wide variety of microalgae strains.

Algae producers know they don’t have the right technology for sustainable harvesting, but they aren’t sure the new technology will work for them. This leads to wasteful and lengthy evaluation periods.

This new trial-size model cuts through that process by letting producers evaluate very quickly and make a decision to move up to full scale. The Model 4 is also perfect for ongoing use in research labs.

The Model 4 carries a manufacturer’s suggested price of $50,000, with credits for strategic partners who sign a multi-phase collaboration agreement with OriginOil. Additional credits will be available for upgrading or trading in the Model 4 to larger systems. OriginOil will also offer training and certification in high-speed algae production and harvesting at its Los Angeles headquarters.

Algae Appliance Model 20

Announced in Fall 2011, the Model 20 is the next step up from the Model 4. Its flow rate is variable from 2 to 20 liters per minute (.5 to 5 GPM), with the potential to remove up to 90% of the initial water volume at the harvesting stage.
