Membrane-Based Ammonia Removal: What Project Owners Should Know
High-ammonia wastewater is common in chemical, fertilizer, landfill leachate, coking, pharmaceutical, food processing and some industrial production processes. Traditional ammonia removal methods may include biological treatment, air stripping, chemical precipitation or other processes. Membrane-based ammonia removal is another technical route. In this process, ammonia in water is transferred across a hydrophobic membrane and absorbed by […]
PTFE Membranes in Wastewater Treatment: Typical Applications
PTFE membranes are made from polytetrafluoroethylene, a material known for chemical resistance and hydrophobic properties. In wastewater treatment, PTFE membranes may be used in different forms, including microfiltration, ultrafiltration, MBR membrane modules and membrane contactors. One application is MBR wastewater treatment. PTFE membrane modules can be used for solid-liquid separation in biological treatment systems. They […]
