Open raceway ponds

At Aban we promote algae cultivation in low-cost open raceway ponds for biofuel applications. We aim at achieving an average biomass productivity of 50-60 g/m2/day using renewable nutrients and poor quality water sources (seawater/brackish water/wastewater streams)

The development of a unique vertical counter-current carbonation column technology for effective CO2 mass transfer from CO2 rich air streams into to algae cultivation medium has resulted in enhanced algal productivity in the cultivation ponds. Compared to direct bubbling of CO2 ponds, the gas transfer rate in carbonation columns is very high which is the reason for the enhanced biomass productivity of algae in carbonation column fed algal ponds.

  • e-zeta Technology

Over the years, various methods such as centrifugation, filtration, flocculation and flotation have been developed in various parts of the world for harvesting microalgae. However, economic viability of these harvesting methods has not been proven yet for commercial-scale biofuel applications. Aban has developed a novel “e-Zeta” process using surface modified metal-oxide catalytic electrodes to harvest algal cells from the culture medium and concentrate the biomass for downstream processing. Integration of e-Zeta process for algae biomass harvesting with other cost effective secondary dewatering techniques is a very promising low-cost approach for commercial-scale algae biofuel operations in future.


Aban has established the proof of concept for the production of biocrude from algae and other renewable sources using a novel thermal conversion technology. Aban is currently developing technologies to upgrade the biocrude to green crude for further refining in existing oil refineries for the production of drop-in biofuels such as green diesel and biojet fuels.
