The Journey of Solids and Scum in Septic Systems

Separation and Settlement of Solids: The Role of Baffles

In the septic system's clarifier, baffles play a crucial role in the separation and settlement of solids. Baffles are designed to prevent scum and solids from bypassing the settling process, ensuring that the wastewater is effectively clarified. As the mixed liquor enters the clarifier, solids are directed to settle at the bottom, while grease and scum rise to the top. The clarified water, now free from solids and scum, continues towards the final disinfection stage.

The proper functioning of baffles is essential for the clarification process, as they facilitate the separation of solids from the wastewater, allowing for a more efficient treatment.

The journey of solids within the septic system is a critical aspect of wastewater management. Here's a brief overview of their path:

• Solids that settle at the bottom of the clarifier are partially returned to the oxidation ditch as Return Activated Sludge (RAS), where they continue to treat incoming wastewater.
• The remaining solids, termed Waste Activated Sludge (WAS), are transported to the solids processing building for final treatment and dewatering.

Ensuring that baffles are properly maintained is vital for the longevity and effectiveness of the septic system. Neglected or damaged baffles can lead to system failure, environmental contamination, and costly repairs.

Scum Removal with Scum Arms: Complementing the Baffles

In the wastewater treatment process, scum arms play a pivotal role in maintaining the efficiency of septic systems. Two scum arms skim the surface of the clarifier to remove any accumulated scum, ensuring that the separation of solids and scum is thorough and effective.

The scum, primarily composed of grease and other light materials, rises to the top of the clarifier. Here, the scum arms facilitate its removal, complementing the function of baffles which prevent the scum from bypassing the settling process. This dual-action system is crucial for the clarification process, where the mixed liquor transitions from the oxidation ditch to the clarifier, allowing for the clarified water to proceed to the final disinfection stage.

The strategic placement and operation of scum arms are essential for the clarification process, as they ensure that the scum does not interfere with the treatment of wastewater or the quality of the effluent.

The effectiveness of scum arms can be observed in the following outcomes:

• Reduction in the amount of scum reaching the weirs
• Improved clarity of the effluent
• Prevention of scum-related blockages and maintenance issues

Regular inspection and maintenance of scum arms are as important as the upkeep of baffles to prevent system failure and to ensure the longevity and safety of the septic system.

The Fate of Waste Activated Sludge (WAS) and Return Activated Sludge (RAS)

In the intricate ecosystem of a septic system, Waste Activated Sludge (WAS) and Return Activated Sludge (RAS) play pivotal roles. After the initial treatment, the solids in the wastewater are split into two streams. RAS is cycled back into the oxidation ditch, contributing to the ongoing treatment of incoming wastewater. Conversely, WAS is directed towards the solids processing building for final treatment and dewatering.

The process of handling WAS and RAS is essential for the overall efficiency of the septic system. It ensures that the system operates within its designed capacity, preventing overloading and potential system failure.

The treatment of WAS involves thickening, which is achieved using polymers and solid bowl centrifuges. This method can increase the dry solids content to between 20% and 24%, significantly reducing the volume of sludge. The digestion process further decreases the sludge amount by 30% to 40%, leading to cost savings on polymer usage and improved dewatering characteristics.

Here's a quick overview of the sludge reduction percentages:
