Assumed Solid Loading Rate of Circular Settling Tanks Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Solid Loading Rate - (Measured in Kilogram per Second Square Meter) - Solid Loading Rate is the amount of solids applied per unit area of a treatment process, such as a clarifier, typically measured in kilograms per square meter per day (kg/m²/day).
Maximum Solids - (Measured in Kilogram per Second) - Maximum Solids refer to the highest concentration of suspended particulates in a given system, such as a wastewater treatment tank.
Surface Area - (Measured in Square Meter) - Surface Area is the horizontal area available for sedimentation, impacting the tank's capacity to separate solids, typically measured in square meters (m²).

STEP 1: Convert Input(s) to Base Unit

Maximum Solids: 80 Kilogram per Day --> 0.000925925925925926 Kilogram per Second (Check conversion here)
Surface Area: 4 Square Meter --> 4 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SL_r = (S_max/SA) --> (0.000925925925925926/4)

Evaluating ... ...

SL_r = 0.000231481481481481

STEP 3: Convert Result to Output's Unit

0.000231481481481481 Kilogram per Second Square Meter -->20 kilogram per Day Square Meter (Check conversion here)

FINAL ANSWER

20 kilogram per Day Square Meter <-- Solid Loading Rate

(Calculation completed in 00.020 seconds)

Assumed Solid Loading Rate of Circular Settling Tanks Formula

Solid Loading Rate = (Maximum Solids/Surface Area)
SL_r = (S_max/SA)

What is Solid Loading Rate?

Solid Loading Rate (SLR) SLR is the number 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.
