Low Cost Dewatering and Drying- Algae Venture System
It is a well-known fact that harvesting and drying adds considerably to the overall cost of oil from algae. Algae Venture System, a company in US ewhich has been by ARPA has devised a low cost dewatering and drying system and they have been considered to be having the most scientific method.
Here are the details:
The Algae Venture System’s HDD system?s novel absorbent moving belt harvester reduces the energy costs of harvesting, dewatering, and drying microalgae by over 90%. The biggest breakthrough is that the harvester pulls water from the screened algae using low-energy capillary action. Thus the algae is dewatered without pressure and separates easily from the screen when dry. Drying can occur naturally through evaporation or mechanically with a small amount of waste heat. The technology offers the potential to transform the economics of algae-based biofuel production by removing one of the major barriers to large scale commercialization.
