AbstractAlgal-bacterial granules have been drawing attention in wastewater treatment due to their rapid settling ability and efficient nutrient removal performance. This study evaluated the impact of air flow rates on nitrogen removal and the formation of algal-bacterial granules in domestic wastewater treatment. The highest nitrogen removal efficiency was achieved by operating with two separate feedings and the addition of an external carbon source.

Reducing atmospheric concentrations of methane—the potent, yet short-lived greenhouse gas—is critical for slowing the rise of global temperatures. Dairy and beef cattle, the world’s most numerous ruminants, belch out about 100 teragrams (Tg) of methane (CH4) every year. Globally, enteric methane emissions rival those from the oil and gas industry.
