Biological nutrient removal

ENTEX’s IFAS and SFF systems provide tremendous flexibility in designing systems capable of meeting increasingly stringent effluent standards, including nitrogen removal. Additionally, the substantial space saved by using Entex’s systems can provide the critical additional space needed to support biological phosphorus removal. Whether you’re considering our fixed media BioWeb systems or moving media BioPortz systems, both provide exceptional performance typically at substantially lower costs than conventional solutions. When combined into our IMFAS hybrid membrane systems, exceptional performance in total nitrogen removal can be incorporated with exceptionally cost effective systems.

Entex’s systems provide film thicknesses that support simultaneous nitrification and denitrification. Under the aerobic layer of biomass is an anoxic layer that provides additional denitrification in the aerobic zone, recovering alkalinity lost in the nitrification zone, and saving on aeration requirements by metabolizing organics anoxically.
