High-Basicity Aluminum Precipitation for Biotechnological Liquid Decolorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrially produced biotechnological liquids often have a strong, dark color due to metabolic processes, which complicates the separation of color-forming substances and reduces the quality and sales value of products like enzymes and organic acids, as existing chromatographic methods are expensive and inefficient.
Innovation Solution
Adding a high-basicity aluminum compound with a basicity of at least 50% to the biotechnological liquid to precipitate or form flocks of color-forming substances, which can then be easily separated, while maintaining the liquid's enzyme activity and pH levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If chromatographic procedures are used to reduce color, then color reduction is achieved, but production costs increase significantly
Solution Approach 1:
The patent changes the chemical parameter of the aluminum compound by using high-basicity aluminum compounds (basicity ≥50%, preferably ≥70%) instead of conventional low-basicity aluminum salts. This parameter change enables effective color reduction through precipitation while avoiding the high costs of chromatographic procedures, resolving the contradiction between color reduction effectiveness and production cost
Solution Approach 2:
The patent employs inexpensive aluminum compounds (such as aluminum hydroxide, aluminum sulfate, or aluminum chloride with high basicity) as disposable precipitating agents. These cheap chemicals effectively remove color-forming substances through simple precipitation and filtration, replacing expensive chromatographic materials and significantly reducing production costs while achieving the desired color reduction
2Object-affected harmful factors
If colour forming substances are separated, then color is reduced, but separation becomes complicated due to full solubility
Solution Approach 1:
The patent induces a phase transition by adding high-basicity aluminum compounds to the biotechnological liquid, causing color-forming substances to transition from a dissolved state to an insoluble precipitate or flock form. This phase change simplifies separation dramatically, as the precipitated materials can be easily removed by filtration or centrifugation, resolving the contradiction between color reduction and separation complexity
Solution Approach 2:
The high-basicity aluminum compound acts as an intermediary agent that binds to color-forming substances and facilitates their separation. The aluminum compound forms insoluble complexes or precipitates with the soluble color-forming substances, creating a new phase that can be easily separated from the liquid, thus simplifying the separation process while effectively reducing color
3Ease of manufacture
If conventional aluminum compounds are used, then cost is reduced, but color reduction effectiveness is insufficient
Solution Approach 1:
The patent specifically changes the basicity parameter of aluminum compounds from conventional low levels to high levels (basicity ≥50%, preferably ≥70%). This parameter enhancement maintains the low cost advantage of aluminum-based compounds while dramatically improving their color reduction effectiveness, as the high basicity enables more efficient precipitation of color-forming substances
