Cake Solids Formula:
From: | To: |
Definition: This calculator determines the solid content percentage in dewatered cake based on dry cake rate and wet cake discharge rate.
Purpose: It helps in wastewater treatment and industrial processes to evaluate the efficiency of dewatering equipment.
The calculator uses the formula:
Where:
Explanation: The ratio of dry cake mass to wet cake mass gives the solids content in the dewatered material.
Details: Higher cake solids indicate better dewatering performance, reduced disposal costs, and more efficient operation.
Tips: Enter the dry cake rate and wet cake discharge rate in kg/s. Both values must be > 0.
Q1: What is a typical cake solids percentage?
A: Typical values range from 15-40% (0.15-0.4 decimal) depending on the material and dewatering equipment.
Q2: How do I measure dry cake rate?
A: Dry cake rate is measured by weighing the dewatered solids after complete drying.
Q3: What affects cake solids percentage?
A: Factors include feed solids concentration, polymer dosage, dewatering time, and equipment type.
Q4: Why is wet cake discharge used in the calculation?
A: Wet cake discharge represents the actual output from the dewatering equipment including both solids and residual water.
Q5: How can I improve cake solids percentage?
A: Optimize polymer dosage, increase dewatering time, or upgrade to more efficient dewatering equipment.
