Succinic-Tartaric Acid Compositions for Phosphate-Free Lead Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment compositions to reduce lead dissolution in drinking water often rely on phosphates, which contribute to environmental issues like algae blooms, and lack effective alternatives with additional health benefits.
Innovation Solution
A multi-functional lead anti-dissolution composition comprising succinic acid (30-70% by weight) and tartaric acid (30-70% by weight), along with optional organic acids like lactic, phytic, mandelic, or glycolic acid, that do not include phosphates, providing anti-inflammatory properties and reducing lead dissolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phosphates are used in water treatment compositions to reduce lead dissolution, then lead dissolution is reduced, but environmental harm increases due to algae blooms
Solution Approach 1:
The invention extracts and removes phosphates from the water treatment composition entirely, replacing them with organic acids (succinic acid, tartaric acid, citric acid, lactic acid, phytic acid, mandelic acid, or glycolic acid). This extraction eliminates the harmful environmental effect of phosphate-induced algae blooms while maintaining the primary function of reducing lead dissolution through alternative chemical mechanisms.
Solution Approach 2:
The invention changes the chemical parameters of the treatment composition by substituting inorganic phosphates with organic acids. This parameter change alters the chemical mechanism from phosphate-based lead complexation to organic acid-based lead complexation and inhibition, achieving the same protective function without the harmful environmental byproducts associated with phosphates.
2Reliability
If single-function lead anti-dissolution compositions are used, then lead dissolution is reduced, but additional health benefits are lost
Solution Approach 1:
The invention makes the water treatment composition multi-functional by selecting organic acids that simultaneously provide lead dissolution reduction and anti-inflammatory health benefits. The composition not only protects against lead contamination but also contributes beneficial compounds to drinking water that can reduce inflammation, thereby serving multiple protective functions in a single treatment system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively reduces lead dissolution in drinking water while minimizing phosphate use, offering health benefits such as anti-inflammatory properties and avoiding environmental harm.
Implementation Method 1
The organic acids in the composition form protective films on lead surfaces through chemical bonding, preventing oxidation of lead atoms into soluble lead ions that could be carried by water
Implementation Method 2
The multi-functional lead anti-dissolution composition uses organic acids that complex with lead ions through chelation, effectively reducing the amount of lead that dissolves into drinking water supplies

AI summary
A multi-functional lead anti-dissolution composition based on 100 parts by weight consisting of: a succinic acid in an amount of from 30 to 70 percent by weight; and a tartaric acid in an amount of from 70 to 30 percent by weight. The composition does not include any phosphates, thereby not contributing to the phosphate footprint in the water supply. The composition includes organic acids that have anti-inflammatory properties in addition to reducing lead dissolution in drinking water.
