Details:	SUMMARY: Filter Turbidity Profile DETAILS: I requested a visit to perform a review of turbidity performed by plant personnel. The profiles I have done for other plants not only record turbidities after a backwash they also record turbidity during the backwash. Turbidity during a backwash will provide useful information about the backwash process usually not considered by most plant personnel. Information gained often provides an opportunity to optimize the process which in turn influences the entire filter profile. ACTION NEEDED: Be available to the system for technical assistance if requested.
