Objectives
Improved Treatment Efficiency
- Primary objective:
- 50% reduction in COD which was above 30% above discharge compliance
- Secondary objective:
- 50% reduction in TSS.
- 30% reduction in sludge.
- Improved water clarity and system efficiency.
- Offensive odor reduction or elimination
Plant Characteristics
Operational hours: 24 hours daily / 6 days per week
Flow rate: 1000 to 1,200 cubic meters per day (250,000-300,000 gallons per day)
Holding Time: 24 hours
Treatment Dosage
15 ppm of ACCELL
Results
- Primary Objective:
- 3 weeks: 60% reduction in COD discharge levels
- Secondary objectives:
- 2 days: DO significantly increased
- 3 days: Water clarity improved dramatically
- 5 days: Organic odor eliminated
- 3 weeks: Slight reduction in TSS that is mainly inorganic
Other Comments
- Floating “grease balls” were observed in the precipitating tanks during the first month This was grease being purged from the bottom and sides of the tanks. The “grease balls” were no longer present after 4 to 5 weeks of ACCELL treatment.
- During the early part of the trial, the wastewater in the aeration tanks turned from a medium brown to a light tan color. After one month of ACCELL treatment, the water was clearer than it had ever been in plant history.
