Assumed Solid Loading Rate of Circular Settling Tanks Solution

STEP 0: Pre-Calculation Summary

Formula Used

Solid Loading Rate = (Maximum Solids/Surface Area)
A_Q = (S/SA)
This formula uses 3 Variables

Variables Used

Solid Loading Rate - (Measured in Kilogram per Second Square Meter) - Solid Loading Rate is the rate at which solid is loaded in a given surface area as mass flow rate.
Maximum Solids - (Measured in Kilogram per Second) - Maximum Solids entering the clarifier in circular settling tank.
Surface Area - (Measured in Square Meter) - The Surface Area of a three-dimensional shape is the sum of all of the surface areas of each of the sides.

STEP 1: Convert Input(s) to Base Unit

Maximum Solids: 3 Kilogram per Day --> 3.47222222222222E-05 Kilogram per Second (Check conversion here)
Surface Area: 18 Square Meter --> 18 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_Q = (S/SA) --> (3.47222222222222E-05/18)

Evaluating ... ...

A_Q = 1.92901234567901E-06

STEP 3: Convert Result to Output's Unit

1.92901234567901E-06 Kilogram per Second Square Meter -->0.166666666666667 kilogram per Day Square Meter (Check conversion here)

FINAL ANSWER

0.166666666666667 ≈ 0.166667 kilogram per Day Square Meter <-- Solid Loading Rate

Mixed Liquor Suspended Solids in Aeration Tank using Maximum Solids

Go MLSS = (Maximum Solids in Aeriation Tank/((Peak Discharge+Return Activated Sludge)*8.34))

Design Surface Loading Rate given Surface Area of Circular Settling Tank

Go Surface Loading Rate = (Peak Discharge/Surface Area)

Average Daily Load using Peak Discharge in Circular Settling Tanks

Go Average Daily Load = (Peak Discharge/Peaking factor)

Peaking Factor using Peak Discharge in Circular Settling Tanks

Go Peaking factor = (Peak Discharge/Average Daily Load)

Peak Discharge given Surface Area of Circular Settling Tank

Go Peak Discharge = (Surface Area*Surface Loading Rate)

Surface Area of Circular Settling Tank

Go Surface Area = (Peak Discharge/Surface Loading Rate)

Solids Processed given Actual Solid Loading Rate

Go Solid Processed = (Solid Loading Rate*Surface Area)

Assumed Solid Loading Rate of Circular Settling Tanks

Go Solid Loading Rate = (Maximum Solids/Surface Area)

Peak Discharge in Circular Settling Tanks

Go Peak Discharge = Average Daily Load*Peaking factor

Total Settling Tank Surface Area given Actual Solid Loading Rate

Go Surface Area = Solid Processed/Solid Loading Rate

Actual Solid Loading Rate of Circular Settling Tanks

Go Solid Loading Rate = Solid Processed/Surface Area

Maximum Solids given Solid Loading Rate

Go Maximum Solids = Surface Area*Solid Loading Rate

Surface Area given Solid Loading Rate

Go Surface Area = Maximum Solids/Solid Loading Rate

Influent Flow Rate given Return Activated Sludge Flow Rate

Go Average Daily Influent Flow Rate = (Return Activated Sludge/1.25)

Return Activated Sludge Flow Rate

Go Return Activated Sludge = 1.25*Average Daily Influent Flow Rate

Assumed Solid Loading Rate of Circular Settling Tanks Formula

Solid Loading Rate = (Maximum Solids/Surface Area)
A_Q = (S/SA)

What is Solid Loading Rate ?

Solids loading rate (SLR) SLR is the amount of solids per day that can be removed per square foot of surface area by a clarifier (lbs/day/ft²). If the SLR increases above the design limits of the clarifier, there will be an increase in effluent solids.
