Wastewater Treatment Plant Flow Diagram

Treatment Process: Integrated Fixed Film Activated Sludge (IFAS)

• Hybrid treatment system that combines fixed film technology with conventional activated sludge
• The immersed media provides surface area for biological growth to attach
• Addition of media to an aeration basin to increase biomass concentrations assists in nitrification.
• IFAS Advantages:
  1. Allows secondary treatment expansion without additional aeration basins.
  2. Improved biomass capacity which improves the nitrification capacity.
  3. Increased resistance to hydraulic washouts.
  4. Lower suspended MLSS concentrations improving secondary clarifier performance.

Average flow: 3.5 Million Gallons per Day

• Maintain and operate 10 pump stations, and 1 flood station
• Maintain and operate 2 NYSDEC flood stations ELAP Certified Laboratory
• Monitor 8 participants in the Industrial Pretreatment Program
• Sodium Hypochlorite disinfection
• Anaerobic digestion
• Monitor and collect weather data for submittal to the National Weather Service in Buffalo, NY
• Process 368 dry tons of solids per year

Goal

To produce a final effluent that is in compliance with SPDES required limits. This operating strategy accounts for the following conditions that directly impact operations and effluent quality:

• Site specific solids, nitrogenous and carbonaceous loading.
• Seasonal variations in biological activity
• Seasonal and daily variations in flow
• Infiltration and Inflow
