Solution Overview
Problem
Existing septic systems face issues with clogging of media, limited geometry constraints due to landscaping regulations, and inefficient effluent distribution, which affect treatment efficiency and soil absorption.
Innovation Solution
A wastewater management system comprising a septic tank, pump tank, pressure tank, emitter modules, and pods with sand, where effluent is pressurized to 30-50 PSI, filtered, and distributed through emitter modules to the soil, ensuring consistent flow and absorption, even on sloping sites, with modular and easily replaceable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If effluent is introduced at high pressure into the basin, then flow through the granular medium is improved, but the geometry of the basin is constrained by landscaping regulations
Solution Approach 1:
The system divides the treatment process into separate functional modules: a pump tank for pressurization, a filter system for purification, and multiple emitter modules distributed across several pods for effluent application. This segmentation allows each component to be optimized independently, with the pump tank handling pressure generation without being constrained by landscaping regulations on basin geometry.
Solution Approach 2:
The pump tank serves as an intermediary between the effluent source and the emitter modules, decoupling the pressure generation function from the distribution system. This intermediary allows high-pressure effluent to be generated and stored separately from the geometry-constrained basin area, enabling flexible placement of treatment components.
2Reliability
If the lower medium and granular medium are used for treatment, then biological contamination is removed, but the media becomes clogged with floc and requires replacement
Solution Approach 1:
The system uses different media types in different locations: a lower medium for initial settling and a granular medium for filtration. The emitter modules are positioned to apply effluent directly to the soil profile below the granular medium, creating localized treatment zones that reduce overall media clogging and extend replacement intervals.
Solution Approach 2:
The system extracts and removes floc and solids through the filter system before effluent reaches the granular medium and soil. By taking out contaminants at the filtration stage, the granular medium is protected from extensive clogging, reducing the frequency of media replacement and maintaining treatment effectiveness over time.
3Productivity
If effluent is distributed through multiple emitter modules, then consistent flow to soil is achieved, but system complexity increases
Solution Approach 1:
The distribution system is segmented into multiple independent emitter modules that can be configured in series or parallel arrangements. Each module contains its own flow control and emission mechanisms, allowing consistent effluent distribution across multiple pods while maintaining modular simplicity. The standardized module design reduces overall system complexity despite the increased number of components.
