Permeable Barrier Flow Element for Contaminant Segregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing contaminants in confined spaces, such as livestock enclosures, fail to effectively segregate and mitigate harmful gases and odors, often redirecting them outdoors, where they can cause pollution and health hazards, and do not address the re-entry of toxic chemicals and organisms into the enclosure.
Innovation Solution
A novel one-way barrier system with a flow element that segregates contaminated gases from solids and liquids, using a decontaminating agent like Titanium Dioxide to treat the gases, preventing re-entry and improving air quality by creating a treated gas that can be recirculated or released safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional venting systems are used to remove contaminants from enclosed spaces, then airborne contaminants can be expelled outward, but harmful contaminants are merely shuffled from one place to another and ultimately pollute the outdoor environment
Solution Approach 1:
The patent introduces a permeable barrier system with flow elements as an intermediary between the indoor and outdoor environments. This barrier allows contaminated air to pass through while capturing and treating harmful contaminants, preventing them from being released outdoors. The system mediates the transition of air between spaces while actively removing pollutants through filtration and chemical treatment processes.
Solution Approach 2:
The system extracts harmful contaminants from the air stream as it passes through the permeable barrier. Using filters, adsorbents, and chemical treatment media, the system selectively removes pollutants such as ammonia, hydrogen sulfide, and particulate matter from the contaminated air, separating them from the breathable air that can be recirculated or safely discharged.
2Object-affected harmful factors
If chemical infusions, filters, scrubbers, and absorbents are used to control harmful substances, then contaminants can be treated, but these systems are labour-intensive and costly
Solution Approach 1:
The patent combines multiple contaminant control functions into a single integrated permeable barrier system. The flow elements incorporate filtration media, adsorbent materials, and chemical treatment capabilities within one structure, eliminating the need for separate labour-intensive systems. This merged approach reduces operational complexity while maintaining effective contaminant control.
Solution Approach 2:
The permeable barrier system is designed to operate with minimal human intervention. The passive flow through the barrier allows contaminants to be automatically captured and treated as air moves through the structure, reducing the need for active management and labour-intensive operations associated with traditional treatment systems.
3Ease of operation
If open venting is used in grating designs, then contaminated waste material can drain into the sump, but noxious and toxic chemicals can escape into the atmosphere or enter confined living and work spaces
Solution Approach 1:
The patent uses a permeable barrier with flow elements that act as a flexible yet functional interface between waste areas and living spaces. This thin film-like structure allows liquid waste to pass through while blocking gaseous contaminants, providing a selective barrier that maintains operational efficiency while protecting occupants from harmful chemicals.
Solution Approach 2:
The permeable barrier system applies different functional properties to different parts of the grating structure. The flow elements are designed with specific permeability characteristics that allow liquid passage while blocking gas, creating localized zones of selective permeability throughout the grating assembly to address both drainage and contamination prevention needs.
4Productivity
If floor gratings with vertical openings are used to allow waste drainage, then contaminated matter can flow into the sump, but trapped toxic and odorous fumes remain in the enclosure
Solution Approach 1:
The permeable barrier serves as an intermediary that facilitates waste removal while simultaneously addressing air quality. As contaminated air and waste pass through the flow elements, the barrier captures and treats odorous fumes and toxic gases, mediating between the need for efficient waste drainage and the need to maintain acceptable air quality in the enclosure.

AI summary
An arrangement and process of mitigating contaminants has a flow element intermediate a first space with contaminated matter (including contaminated gas) and a second space. Contaminated matter is drawn from the first space into the flow element and then urged into segregated contaminated gas and residual contaminated matter collected in the second space. Segregated contaminated gas is merged with gas from the second space to form mixed gas and treated to form primary treated gas which is directed to generate at least some of the drawing of contaminated matter from the first space into the flow element. Mixed gas can be treated by passing it through passages in the flow element coated with decontaminating agent and/or through a decontamination unit. The flow element allows for air flow to effectively act as a one-way barrier obstructing migration of contaminated matter from the second space back to the first space.
