Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing water containing permanganate ions using organic iron compounds result in significant precipitate formation that takes several days to settle, hindering efficient production and shipment.
Innovation Solution
Dissolve divalent inorganic iron and manganese compounds in water with a pH of less than 3.5 and introduce ozone microbubbles, without using organic iron compounds, to stabilize permanganate ions over a long period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If organic iron compounds are used as production raw materials, then permanganate ions can be generated in water, but significant precipitate formation occurs that takes several days to settle
Solution Approach 1:
The invention changes the chemical composition parameters by replacing organic iron compounds with inorganic iron compounds (such as iron sulfate or iron chloride) as raw materials. This parameter change eliminates the formation of organic iron precipitates that caused settling issues, while still enabling permanganate ion generation through oxidation by ozone microbubbles.
2Productivity
If permanganate ions are prepared by dissolving permanganate compounds in water, then the solution can be prepared quickly, but the permanganate ions are reduced and disappear within a short period of time
Solution Approach 1:
The invention applies preliminary action by adding inorganic iron compounds and divalent manganese compounds to the water before introducing ozone microbubbles. The iron compounds are oxidized first to form ferric ions, which then catalyze the oxidation of manganese compounds to permanganate ions. This staged approach ensures stable permanganate ion formation with prolonged stability compared to direct dissolution methods.
3Reliability
If a precipitate is formed in the water containing permanganate ions, then the permanganate ions can be stabilized, but it takes time to filter the formed precipitate before shipment
Solution Approach 1:
The invention changes the chemical parameters by using inorganic iron compounds instead of organic iron compounds, which fundamentally alters the precipitation behavior. The inorganic iron-based precipitates formed are different in composition and properties from organic iron precipitates, resulting in faster settling and reduced filtration requirements while maintaining permanganate ion stability.
