Inorganic Cleaning Agent with Clay Mineral for Low BOD Wastewater
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional environmentally friendly cleaning agents often contain organic substances, leading to increased biochemical oxygen demand (BOD) and chemical oxygen demand (COD) in wastewater, which complicates pollution control, and achieving effective cleaning without organic materials is challenging, especially for smear removal.
Innovation Solution
A cleaning agent comprising a clay mineral, such as montmorillonite, and inorganic salts like sodium carbonate, with a total organic substance content of 2% or less, which is designed to minimize BOD and COD by eliminating organic substances and using inorganic powders for enhanced cleaning and sensory experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If organic substances such as surfactants are used for smear removal, then cleaning effect is achieved, but BOD and COD in wastewater increase
Solution Approach 1:
The patent replaces chemical cleaning mechanisms (organic surfactants) with physical mechanisms (clay mineral particles and inorganic salts). The clay minerals provide mechanical abrasion and electrostatic attraction for smear removal, while inorganic salts like sodium carbonate and lithium carbonate provide buffering and softening effects, achieving cleaning without organic substances that would increase BOD and COD
Solution Approach 2:
The patent changes the chemical composition parameters by substituting organic carbon-based surfactants with inorganic clay minerals and salts. This parameter change eliminates organic carbon content while maintaining cleaning functionality through different physical-chemical properties of the inorganic materials
2Object-affected harmful factors
If natural materials are used instead of synthetic materials, then environmental burden is reduced, but BOD and COD still increase due to organic content
Solution Approach 1:
The patent extracts and removes the organic substance component entirely from the cleaning agent formulation. By using only inorganic clay minerals and salts, the formulation eliminates the source of organic carbon that would otherwise increase BOD and COD, while still providing effective cleaning functionality
Solution Approach 2:
The patent employs readily available inorganic clay minerals and salts that are environmentally benign and easily degradable. These inorganic materials do not persist in the environment as organic pollutants, effectively treating wastewater without long-term environmental burden
3Quantity of substance
If inorganic salts containing negative hydrated ions are used, then organic substance content is lowered, but cleaning effect is insufficient
Solution Approach 1:
The patent creates a composite formulation combining multiple inorganic components: clay minerals (providing mechanical and electrostatic cleaning), inorganic salts like sodium carbonate and lithium carbonate (providing buffering and softening), and optionally inorganic powders. This composite approach achieves sufficient cleaning effect while maintaining low organic content
Solution Approach 2:
The patent assigns different functional properties to different inorganic components based on their specific characteristics. Clay minerals provide specific electrostatic and mechanical properties, while inorganic salts provide buffering and softening, creating a synergistic effect that achieves adequate cleaning performance
