Water Science & Technology Special Issue on

Biochemical and Thermochemical Energy Conversion of Wastewater Algal Biomass



With the world's growing population, the production of wastewater forms one of the major environmental challenges. By rapidly growing cultures of algae in wastewater, both nitrogen and phosphorus can be removed, which results in valuable algal biomass. This algal biomass is rich in nutrients and is recognized as a potentially valuable source for obtaining bioenergy. Microalgae may contribute to economically sustainable bioenergy production. However, different biochemical, environmental, and economic challenges need to be addressed before making it available commercially. Particularly the cost and energy demand for harvesting algal biomass by methods such as centrifugation, and flocculation with alum and ferric chloride are high. So further development of harvesting techniques needs to be supported. Although 10,000 algae species are available, only a few 100s are investigated and cultivated for industrial applications. It is thus necessary to optimize and enhance the use of unexploited algal species and, in parallel, to develop new efficient methods for their cultivation and harvesting.

This Special Issue invites papers dealing with the various aspects of biochemical and thermochemical energy conversion of wastewater algal biomass. Papers are preferably sought that critically examine the advantages and disadvantages of the energy conversion process, the cultivation of new promising algal species for energy production, harvesting technologies of various microalgae, bioenergy concepts and techniques, through reviews, case studies, analytical methods, and tools.

We are pleased to invite you to submit a manuscript to Water Science & Technology for peer review and possible publication in a Special Issue entitled ‘Biochemical and Thermochemical Energy Conversion of Wastewater Algal Biomass’.
