riginOil, Inc. has announced that it has tripled the capacity of its entry-level algae harvester from four to twelve liters per minute at no additional cost, with improved energy efficiency. The EWS (Electro Water Separation) algae unit, now designated as Model 12, offers reduced energy consumption due to an improved design that reduces electrical resistance and boosts harvesting performance.
The available intelligent power management system can take readings via sensors on parameters such as salinity, temperature, pH and algal density, to better manage and dispense energy to achieve optimum algal harvest. It is designed to 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.
In his presentation of the new unit at the recent ABS, Jose Sanchez, OriginOil VP of quality assurance and services, said that detailed data is now available on the bacterial control capability. He said that, according to independent testing, “bacteria exposed to EWS Algae is reduced from a factor of 99% (referred as ‘Log 2’ by biologists) to a factor of 99.9999999% (referred as ‘Log 9’), depending on the period of exposure. The algae passed through EWS is typically left largely unharmed.”
Sanchez continued, “We have found that the new EWS Algae system can help trigger metabolic processes that can transform Hematococcus pluvialis from its green phase, to the red phase in which the stressed cells encyst and astaxanthin forms as a pigment.” The process is documented in an Application Note now on the OriginOil website.
