Percent Solids Recovery Formula:
From: | To: |
Definition: Percent Solids Recovery is the mass of solids in the cake divided by the mass of solids in the feed.
Purpose: It helps determine the efficiency of solids capture in separation processes like centrifugation or filtration.
The calculator uses the formula:
Where:
Explanation: The formula calculates what percentage of the feed solids are recovered in the cake, accounting for solids lost in the centrate.
Details: Measuring solids recovery helps optimize separation processes, reduce waste, and improve process efficiency in water treatment, mining, and industrial applications.
Tips: Enter the cake solids percentage (Cs), feed solids percentage (F), and centrate solids percentage (Cc). All values must be ≥ 0.
Q1: What is a good solids recovery percentage?
A: Typically 90-99% is considered good, depending on the application and equipment used.
Q2: How does centrate solids affect recovery?
A: Higher centrate solids mean more solids are lost, resulting in lower recovery percentages.
Q3: What if my cake solids equal centrate solids?
A: The formula becomes undefined (division by zero) as this suggests no separation occurred.
Q4: Can recovery exceed 100%?
A: No, recovery percentages above 100% indicate measurement errors in the input values.
Q5: How can I improve solids recovery?
A: Optimize process parameters like feed rate, G-force, or polymer dosage in centrifugation.
