How is Gould Sludge Age (GSA) calculated?

Dividing the total pounds of TSS by the pounds of TSS entering the aerator
Multiplying the total pounds of TSS by the pounds of TSS entering the aerator
Adding the total pounds of TSS to the incoming TSS
Subtracting the pounds of TSS entering the aerator from total pounds of TSS

The correct answer is: Dividing the total pounds of TSS by the pounds of TSS entering the aerator

The calculation of Gould Sludge Age (GSA) involves determining the retention time of the solids within the wastewater treatment system, which is a critical factor in understanding the biological treatment process. The correct method to calculate GSA is by taking the total pounds of Total Suspended Solids (TSS) in the system and dividing it by the pounds of TSS entering the aerator. This approach provides a ratio that indicates how long the solids are retained in the aeration tank relative to the incoming solids. It helps operators assess the effectiveness of the treatment process and to optimize the operation for better performance. Other choices do not reflect the appropriate approach for calculating GSA and could lead to misunderstandings about how long solids stay in the treatment system, which is essential for effective wastewater management.
