1. What is Percent Solids Recovery?

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.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \%R \) — Percent Solids Recovery
• \( Cs \) — Cake Solids in Percent
• \( F \) — Feed Solids in Percent
• \( Cc \) — Centrate Solids in Percent

Explanation: The formula calculates what percentage of the feed solids are recovered in the cake, accounting for solids lost in the centrate.

3. Importance of Solids Recovery Calculation

Details: Measuring solids recovery helps optimize separation processes, reduce waste, and improve process efficiency in water treatment, mining, and industrial applications.

4. Using the Calculator

Tips: Enter the cake solids percentage (Cs), feed solids percentage (F), and centrate solids percentage (Cc). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

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.
