About Sludge Age
Sludge Age, also known as Mean Cell Residence Time (MCRT) or Solids Retention Time (SRT), is a critical parameter in activated sludge wastewater treatment processes. It represents the average time that microorganisms stay in the system.
Parameters Explained:
- MLSS: Mixed Liquor Suspended Solids - concentration of suspended solids in the aeration tank
- V: Volume of the aeration tank
- WAS flow rate: Waste Activated Sludge flow rate
- WAS_TSS: Total Suspended Solids concentration in waste activated sludge
- Effluent TSS: Total Suspended Solids in the treated effluent
- Q: Effluent flow rate
