Abstract

Nitrogen in wastewater causes many problems in receiving water such as eutrophication and algae bloom. Wastewater problems from the seafood industry are a common and wide spread, especially in the south of Thailand. The seafood industry generally generates large quantity of wastewater containing high concentrations of organic, nitrogen, and solid matter. The wastewater needs to be properly treated before disposal. Constructed wetland can be used for tertiary treatment and nutrient recycling. This research studied the nitrogen removal efficiency of a laboratory scale experiment constructed wetland using cattail (Typha augustifolia) at different HRT at 5, 10, and 15 days and another experimental control unit at 10 day
