Recent Advances in Pond and Algal Technologies for Wastewater Treatment and Resource Recovery

In a global scenario of increasing energy prices and quest for sustainable human activities, wastewater treatment in the 21st century must undergo a dramatic revision of its current practices. These must aim at developing a new generation of energy-efficient and resource-recovery processes, whilst complying with the ever-stricter environmental regulations.

Wastewater treatment using photosynthetic microorganisms can benefit from the knowledge coming from the use of algae to produce biofuels, food supplements or green pharmaceuticals and of microbial physiology of purple photosynthetic bacteria. Likewise, wastewater as a cheap source of nutrients and inorganic carbon is promising for the mass production of algae-based commodities.

This Special Issue brings the latest discoveries on the following topics:

• The potential of microalgae to grow in high strength and domestic wastewaters to remove emerging pollutants and pathogens
• Efficiency of novel photobioreactor configurations
• Mechanisms and recent advances of microalgae harvesting
• Molecular analysis of microbial populations in continuous photobioreactors treating wastewater
• The potential of computational fluid-dynamics for the design of microalgae-based wastewater treatment
• Novel algal biomass valorization strategies
