Flow-way water depth affects algal productivity and nutrient uptake in a filamentous algae nutrient scrubber

Flow-way water depth affects algal productivity and nutrient uptake in a filamentous algae nutrient scrubber

Filamentous algae treatment systems can provide cost-effective treatment of a range of wastewater types. In the current study, filamentous algae nutrient scrubbers (FANS), treating anaerobically digested food-waste centrate, were used to investigate the role of flow-way water depth (5, 10 and 15 mm)...

Zusammenfassung:Filamentous algae treatment systems can provide cost-effective treatment of a range of wastewater types. In the current study, filamentous algae nutrient scrubbers (FANS), treating anaerobically digested food-waste centrate, were used to investigate the role of flow-way water depth (5, 10 and 15 mm) on productivity and nutrient removal. The study found that the proportion of light reaching the surface of the filamentous algae mat ( E mat ) increased with decreasing water depth, with 5-mm depth significantly higher than 10 mm ( p
