SCIENCE, RESEARCH & TECHNOLOGY ROCKY MOUNTAIN WATER MAY 2017 | 35 biomethane from algae enables green-house gas savings of more than 50 per-cent compared to diesel. Furthermore, algae biofuel production per hectare is 10,000 kg methane/hectare/year, enough to fuel 10 vehicles, and double the amount produced by sugar bioetha-nol and palm oil diesel, reported Frank Rogalla in his presentation, Wastewater Treatment and Energy Recovery with Cul-tivation of Microalgae. Conclusions State regulators, municipalities, and other industrialized jurisdictions increasingly are moving toward tertiary wastewater treatment as a means to mitigate the environmental effects of nitrogen, phosphorus, heavy metals, and other components of traditional watewater treatment systems. But tradi-tional systems can be an expensive and energy intensive proposition. Algae-based systems, which make up just a small fraction of tertiary systems in use today, offer a potential solution, providing a low input-energy platform for nutrient recovery with a variety of opportunities for production of value-added coproducts.
