Diffusion Sparging System

Features

• Aeration systems for conventional wastewater activated sludge plants typically account for 45 to 60% of a treatment facility’s total energy use
• The ability to define what improvements will be most cost effective begins with understanding how to create a simplified model of the system
• The equipment used for wastewater aeration is required for the biological process and also to provide mixing to keep solids suspended for more effective treatment
• Although there are many types of aeration systems, the two basic methods of aerating wastewater are through mechanical surface aeration to entrain air into the wastewater by agitation, or by introducing air or pure oxygen with submerged diffusers
• The surface aeration is very energy intensive and almost obsolete nowadays
