Training on Activated Sludge (8 Hour)

This unit examines the principles of treating sewage and other biodegradable wastewaters by mixing, aerating and agitating them with active biomass [activated sludge]. The biomass in this mixture [mixed liquor] utilises the organic components that are present in the wastewater as substrate. Biomass concentrate is subsequently separated from the bulk liquid and most of it is returned for re-use to treat the incoming wastewater.

Key points covered in the unit include:

• The chemical and microbiological principles of AS treatment
• AS process design considerations - volumetric loading, organic loading, sludge loading [f/m ratio] and floc loading; solids retention time [SRT]; sludge age; flows and feeding; methods of aerating and settling mixed liquor; recycling biomass - returned activated sludge [RAS]; treatment/disposal options for the surplus activated sludge [SAS]; extended aeration; oxidation ditches; membrane biological reactors [MBRs] etc.
• Nitrogen and phosphorus removal in an activated sludge plant
• Operational control monitoring parameters - pH, dissolved oxygen; mixed liquor suspended solids [MLSS]; sludge settleability (stirred specific volume index [SSVI], sludge density index [SDI]) etc.
• Operational issues - sludge bulking, filamentous bacteria, foaming, sludge blanket level etc., including examples and case studies
