Scum Pit & Lines
- Keeps waste fluid, soft and pumpable
- Keeps waste from compacting
- Eliminates pockets where gases can build-up. Compression can cause explosions
Primary Clarifiers
- Increases primary settleability of solids
- Decreases scum blanket
Aeration Tank
- Reduces B.O.D.
- Reduces final suspended solids (SS)
- Reduces Foam
- From detergent (white foam)
- From Nocardia* (tan/brown foam)
*Nocardia amarae – Actinomycete – (Bacteria/Funfi)- Extra housekeeping effort
- Blockage of scum removal
- Odor from drying scum
- Health risks associated with pathogens in windblown foam
- Reduction of oxygen transfer at the surface of mechanically aerated basins
- Increased B.O.D. & S.S. in plant effluent when scum escapes from the secondary clarifier
- Reduces Bulking & Rising Sludge
- High nitrogen level (E-Z N)
- High Sludge Volume Index (SVI) – Filamentous Bulking
Trickling Filters
- Promotes growth needed for oxidation
- Digests scum and unwanted slime
- Accelerates the decomposition of slough
- Decreases ponding
RBC’s (Rotating Biological Compacters)
- Digests scum, sludge and unwanted slime from disks and shaft, reducing weight and lessening the chance of bending
- Provides oxygen for growth
- Accelerates the decomposition of slough
Lagoons
- Increases settleability
- Promotes algae growth needed for oxidation
Imhoff Tanks
- Promotes settleability
- Degrades waste build-up in tanks and gas vents
Secondary Clarifiers
- Increases settleability of solids
- Reduces scum blanket
- Reduces B.O.D.
- Reduces final S.S.
- Decreases turbidity, therefor a clearer effluent
- Reduces Bulking (Filamentous Bulking- Sphaerotilus organisms)
- Decreases high Sludge Volume Index (SVI)
Sludge Concentration Tanks, Sludge Thickening Tanks, Aroebic Digesters
- Reduces grease build-ups
- Reduces floatables
- Reduces odor
- Increases density of sludge
- Conditions sludge (breaks-up compacted sludge)
- Expands tank capacity
Anaroebic Digesters
- Reduces Foam – Heavy from Waste Activated Sludge W.A.S.
- Reduces crusting
- Reduces odors
- Increases Methane Production
