Sludge retention time = lbs of SS in the system/lbs of SS leaving system
or
aeration tank MLSS x volume of aeration tank and secondary clarifier (as million gallons) x 8.34 / WAS TSS conc x WAS flow x 8.34 + Effluent TSS conc x Effluent Flow X 8.34

What is the difference between relative retention time and retention time?
the difference between retention time and retention factor is that the retention time is a quatitative value where`s the retention factor is a qualitative on.
What will be the effect of pH on retention time?
Retention time decrease with an increase in pH.
Retention time in Hplc?
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
How do you calculate risk retention?
no of policies renewed/no of potential renewal policies
What is the Retention factor of caffeine?
it depends on the retention time, void time and reagents that you were used on your chromatograph.
What does retention time mean?
The retention time represents the time it takes to an analyte to pass from the column inlet to the detector.
How to calculate Relative retention time?
Divide the retention time of the peak of ineterest (ex. 14.8 min.) by the retention time of the main peak (ex. 15.9 min.) 14.8/15.9 = 0.93 Therefore your RRT is 0.93 Remember, any peak with an RRT <1 elutes before the main peak, and any peak with an RRT >1 elutes after the main peak! What is RRT & RRF in hplc
Which great lake has the shortest retention time?
Lake Erie has the shortest retention time of about 2.7 years
Sludge in engine?
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.
How much water is in sludge from a sewage treatment plant?
I may be wrong but i do believe there is 0.8% water in sludge 60% of the time, all the time.
Are there any advantages in increasing retention time?
The retention time would increase becasue longer distance would be travelled by the analyte!
What is diffrente of retention time and ditention time?
Retention time is the time of passing material(fluids) through the volume of the drum with determined flowrate :Retention time=V/Qwhich Q : flowrateand V : Volumebut Detention time is the time that materials stay in drumin batch systems Detention time equals with Retention time.but in continious systems or semi batch systems denention time is bigger than Retention timecommonly.Detention time= n Retention timewhich n is the number of times which materials(fluids) pass through the the volume of drum.
