Algae

Electro Water Separation™ for Algae (EWS Algae) achieves a smart, continuous flow ‘wet harvest’ system that efficiently dewaters and concentrates micro-algae.

EWS Algae™ is available for licensing as part of complete systems that incorporate upstream and downstream functions such as pelletizing for feed.

EWS Algae solves a major barrier to industrial-scale algae production: how to efficiently harvest small algae particles from very large amounts of water.

The Process is cost-effective and chemical-free.

Benefits of EWS Algae:

  • Choice of cell integrity:
    • Largely live and intact.
    • Stressed to generate astaxanthin.
    • Fully ruptured to release cell contents.
  • Concentrated continuously and at scale to a solids ratio of about 5%.
  • Longer shelf life, due to natural bacterial decontamination.
  • Free of metals and other process contaminants.

Testing Results

EWS has been successfully tested on numerous strains of fresh- and salt-water microalgae, including B. braunii, H. pluvialis, Nannochloropsis sp., Tetraselmis sp., Chlorella sp. and Scenedesmus dimorphus.

EWS is validated to effectively remove harmful invaders and pathogens such as bacteria, rotifers, ciliates, protozoa, amoeba and parasites.

How to get EWS Algae

You can put this technology to work in one of two ways:

  • You can purchase a unit from OriginOil or one of its distributors.
  • You can license the technology as an OriginOil Equipment Manufacturer.

Process Overview

An EWS Algae-based system can be located at a central processing area, or in modules at each pond or bio-reactor pod.
When ready for harvesting, the dilute microalgae culture is fed directly from the growth systems into EWS without requiring prior pretreatment or concentration.
The touch-screen PLC (Process Logic Control) is used to precisely aggregate the algae in a substantially intact, stressed or completely ruptured state, as the downstream application may require.

As the raw algae passes through the system, it is subjected to electrical fields generated in two stages:

  • First stage: aggregation of algae cells.
  • Second stage: extraction of aggregated cells.
Need a higher concentration? Add-on devices are optionally available.

Application Note

Astaxanthin: The Most Valuable Algae Product
EWS Algae helps to industrialize the production of astaxanthin by sanitizing and concentrating the Haematococcus pluvialis (HP) algae for more effective stressing and greater astaxanthin productivity.

Information is available on other high-value product harvesting, such as Omega3s.
