Interval Biocide Dosing for Animal Water Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling microbial populations in animal drinking water are ineffective due to low application concentrations of biocides, which can be detrimental to animal health, and biofilms in water supply systems enhance the survival of pathogens like Campylobacter and Salmonella, leading to health issues and increased mortality in poultry.
Innovation Solution
Introducing percarboxylic acids intermittently into animal drinking water, which effectively decontaminates the gastrointestinal tract without negatively impacting water consumption and decomposes into harmless products, combined with competitive exclusion microorganisms to reduce pathogen colonization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of biocide are incorporated in the drinking water to effectively control microbial populations, then the decontamination effect is improved, but the animal health and physical condition are detrimentally affected
Solution Approach 1:
The patent applies periodic action by dosing biocide intermittently at specific time intervals rather than continuously. The dosing occurs at predetermined times (e.g., morning and evening) at concentrations that are effective for decontamination but not continuously present, allowing animals to be exposed to effective concentrations when needed while avoiding constant exposure that would harm their health.
Solution Approach 2:
The patent implements dynamics by varying the biocide concentration over time - using high concentrations during dosing intervals to achieve decontamination, then reducing to zero or low concentrations during non-dosing intervals to minimize harm to animals. This dynamic concentration adjustment resolves the contradiction between effective decontamination and animal health protection.
2Object-affected harmful factors
If low concentrations of biocide are used in the drinking water to maintain animal health, then the safety for animals is improved, but the decontamination effect becomes marginally or completely ineffective
Solution Approach 1:
The patent uses periodic action to deliver high biocide concentrations at intermittent dosing intervals rather than maintaining constant low concentrations. This ensures that effective decontamination levels are achieved during dosing periods while avoiding continuous exposure that would compromise animal safety, thereby resolving the effectiveness-safety contradiction.
Solution Approach 2:
The patent applies preliminary action by dosing biocide in advance at high concentrations to prevent microbial buildup before it becomes problematic, rather than relying on continuous low-level suppression. This preventive high-dose approach maintains animal safety while ensuring decontamination effectiveness.
3Reliability
If biocide is dosed continuously at effective concentrations to control biofilms, then the microbial growth control is improved, but the water consumption by animals decreases due to detrimental effects
Solution Approach 1:
The patent implements periodic action by dosing biocide intermittently rather than continuously. High concentrations are applied at specific intervals (e.g., twice daily) to control biofilms effectively, while the non-dosing intervals allow animals to consume water without exposure to harmful biocide levels, thus maintaining normal water consumption patterns.
Solution Approach 2:
The patent uses dynamics by dynamically adjusting biocide concentration in the water supply - switching between high dosing concentrations and zero or low non-dosing concentrations. This dynamic approach ensures effective biofilm control during dosing while preserving animal water intake behavior during non-dosing periods.
4Ease of operation
If mineral deposits build up in the water supply system to be removed, then the water flow and pressure are improved, but the system requires more aggressive cleaning that increases complexity
Solution Approach 1:
The patent applies continuity of useful action by using low-level biocide presence during non-dosing intervals to continuously inhibit biofilm formation and mineral deposit accumulation. This ongoing preventive action reduces the buildup of deposits that would require aggressive periodic cleaning, thereby maintaining water flow and pressure without increasing system complexity.

AI summary
The invention provides a method for preventing and/or controlling microbial growth in the digestive tract of living vertebrate animals, particularly food-5 producing animals. Control and/or prevention of microbial growth is achieved by the steps of administering to the animal water treated with a biocide followed by administering untreated water and repeating the cycle. The aqueous stream is constantly offered and subsequently consumed orally by the animal. In an embodiment percarboxylic acid or a mixture of percarboxylic acids and sulfuric acid 10 is provided as the biocide in an aqueous stream.
