The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds.
The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry.
Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.

In these companies, the water to be treated can vary depending on the technology used and on the raw materials. These effluents usually contain high concentrations of contaminants, especially those coming from esterification processes.

Combining industrial performance and sustainable development while remaining competitive requires that the biogas and biofuels industry ensure industrial process safety, reduceoperational costs, implement solutions providing significant savings and comply with environmental regulations, which ultimately lead to the public’s acceptance of a site.

Production of biofuels from certain microalgae and cyanobacteria would appear to be the most promising alternative to current methods, since its yield is very high, sustainable, uses either wastewater, brackish or seawater, does not require the use of agricultural land, does not compete with human food and the cultivation process consumes the CO2noxious gas.
ALGAENERGY is responsibly paving the way towards making microalgal-based biofuels industrially profitable. The R&D projects assigned to this task include work on selection and genetic engineering of different microalgae to produce substantial lipid-carriers, some of them patented, as well as the establishment of a suitable and scalable production process.
