Solution Overview
Problem
Current liquid waste treatment methods, such as aerobic and anaerobic digestion, face inefficiencies in treating wastewater and septic effluent, particularly in reducing biochemical oxygen demand (BOD) and requiring extensive land area for treatment systems.
Innovation Solution
A modular liquid waste treatment system featuring a distribution unit with perforated sidewalls and treatment fins filled with a porous medium, surrounded by an impermeable fabric, which facilitates bacterial digestion and efficient fluid communication for treating liquid waste, including sewage, septic effluent, and industrial effluent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional aerobic or anaerobic digestion systems are used, then liquid waste can be treated, but the land area required for treatment is extensive
Solution Approach 1:
The distribution unit is divided into multiple compartments (first compartment, second compartment, third compartment) separated by walls with openings. This segmentation allows simultaneous aerobic and anaerobic treatment processes within a compact structure, increasing treatment efficiency while reducing the overall land area required compared to conventional single-process systems.
Solution Approach 2:
The treatment fins are positioned within the compartments of the distribution unit, with porous media nested inside the fin structures. This nested arrangement maximizes the treatment surface area within a compact volume, allowing extensive treatment capacity without proportionally increasing the external dimensions and land area occupied.
2Productivity
If conventional liquid waste treatment systems are used, then waste can be treated, but the BOD reduction efficiency is insufficient
Solution Approach 1:
The system creates periodic flow patterns through the distributed openings in compartment walls, allowing wastewater to cyclically move between aerobic and anaerobic zones. This periodic action enhances bacterial digestion efficiency by alternately exposing contaminants to different microbial environments, achieving superior BOD reduction of 90% or greater compared to conventional single-mode systems.
Solution Approach 2:
Different compartments provide different local environments (aerobic vs. anaerobic conditions) to optimize specific treatment functions. The treatment fins with porous media in each compartment create localized high-surface-area zones for bacterial attachment, ensuring effective BOD reduction while maintaining system reliability through distributed treatment capacity.

AI summary
A modular liquid waste treatment system is disclosed. In accordance with some embodiments, the system includes a central distribution unit and one or more treatment fins in flow communication therewith. The distribution unit may be configured to receive liquid waste from a given source and distribute that waste, at least in part, to one or more treatment fins. In turn, bacteria present in a given treatment fin treat the liquid waste, and the resultant treated liquid may drain from the fin to the surrounding environment. In some embodiments, a given treatment fin may include porous media providing a large surface area on which bacteria may grow to facilitate treatment. The system may be installed in and/or above the ground, and in some cases may be surrounded, at least in part, with treatment sand and/or other treatment media. The system may be used in aerobic and/or anaerobic processing of liquid waste.
