Dissolved Air Flotation (DAF) Units - Bio-Augmentation of Oil & Grease

Dissolved Air Flotation (DAF) units and the bio-augmentation of oil and grease using Accepta’s eco-friendly product Accepta 7112. Accepta 7112 is an innovative biological product developed for the bio-augmentation of dissolved air flotation (DAF) units and industrial grease traps. It comprises a highly concentrated powdered formulation, containing a synergistic blend of selectively adapted bacteria, surfactant, and enzymes specifically formulated for the biodegradation of oil and grease in sewer lines and municipal sewage treatment plants.

Accepta 7112 is recommended for a wide variety of municipal applications involving problematic accumulations of FOG.

Benefits of Accepta 7112

Significantly reduces line and pump station maintenance costs.
Liquefies and degrades unwanted oil and grease that upset degreasers.
Enhances the oxygen transfer in the aeration basin.
Enhances organic removal efficiency.
Lowers effluent BOD and COD.
Reduces foaming over the aeration basin surface.
Eliminates bad odours due to grease deposits.

Applications

Accepta 7112 is routinely used by plant operators in lift stations, degreasers, primary clarifiers and aeration basins.

When introduced into a system, Accepta 7112 dissolves rapidly to release its highly active biological materials, which act to emulsify, liquefy and digest oil and grease.

Accepta 7112 is formulated to:

Degrade long chain fatty acids that are known to be persistent and cause 80% of deposits.
Associate with the hydrophobic phase.
Grow at low pH.
Degrade odour causing short-chain volatile fatty acids.

Directions for Use

Accepta 7112 can be added directly to any of the following systems, depending on the locations affected by grease problems:

Lift stations.
Degreasers.
Primary clarifiesr.
Aeration basins.

Accepta 7112 is added directly to the sewage, without preliminary preparation.

The standard dosage rate is 4 Accepta 7112 sachets per week. However, the addition of elevated doses, for up to 6 weeks, may be required to implement the new active biomass.
