Background
A collagen product manufacturer faced challenges in improving the clarity and appearance of its collagen solution during production. The original liquid contained suspended impurities that affected transparency and overall product quality. The customer required a filtration solution capable of producing a clear, transparent, and odor-free filtrate while maintaining stable filtration efficiency.
Filtration Objectives
- Improve solution clarity and transparency
- Reduce turbidity effectively
- Remove suspended particles and impurities
- Maintain stable filtration performance and processing efficiency
- Provide filtered samples for further quality evaluation
Filtration Materials and Equipment
The filtration test was conducted using:
- Plate and frame filtration system
- Vertical filter housing
- Turbidity meter
- Depth filter sheets for primary clarification
- Activated carbon filter sheets for secondary purification and deodorization
Filtration Process
The filtration process consisted of two stages:
- Primary Filtration A clarification-grade filter sheet was used to remove larger suspended particles and reduce initial turbidity.
- Secondary Filtration An activated carbon filter sheet was applied for fine purification, further reducing turbidity while improving odor and overall appearance.
Before filtration, the system was cleaned with acid and alkali solutions and rinsed with purified water until neutral pH conditions were achieved. The filter sheets were pre-flushed with purified water to remove surface fibers and ensure stable operation.
Test Results
The filtration trial demonstrated significant improvement in product clarity:
- After primary filtration, the filtrate turbidity was greatly reduced and the solution became visibly clearer.
- After secondary activated carbon filtration, turbidity decreased further, achieving a transparent appearance with improved visual quality and reduced odor.
- The filtration system maintained stable flow performance throughout the test process.
The test also confirmed that the selected filter sheet combination provided:
- High impurity retention capacity
- Efficient filtration speed
- Stable filtration performance during continuous operation
Final Outcome
Through the optimized two-stage filtration process, the collagen solution achieved significantly improved clarity and product appearance. The selected filtration solution successfully met the customer’s processing requirements and provided a reliable reference for future large-scale production applications.
Advantages of the Solution
- Excellent clarification performance
- Improved product transparency
- Effective odor reduction
- Stable filtration efficiency
- Suitable for collagen, protein, and food ingredient filtration applications
