Air Driven Particle Recirculator for Septic Tank Outlet Baffle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerobic septic systems face issues with clogged filters and high bacterial contamination due to the forced air movement of waste particles, leading to sewage backups and frequent filter cleaning or replacement, as well as the need for clarifier compartments in conventional systems.
Innovation Solution
An air-driven particle recirculator is introduced at the inlet of the outlet baffle or filter assembly, redirecting waste particles away from the discharge point and reducing their entry, thereby eliminating the need for clarifiers and reducing bacterial and solid contaminants, utilizing existing or new septic systems with optional integration into the outlet baffle or filter assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forced air is introduced into the septic tank through a diffuser system, then aerobic bacteria proliferate and waste particles are moved, but waste particles are forced into the outlet baffle or filter assembly causing clogging and sewage backups
Solution Approach 1:
The invention segments the air introduction process into two distinct zones: a diffuser system for general aeration and a separate air inlet directly at the outlet baffle inlet. This segmentation allows different air flow patterns to serve different functions - bulk aeration versus particle redirection - thereby maintaining productivity while preventing filter clogging
Solution Approach 2:
The outlet baffle inlet acts as an intermediary element that receives air flow and uses it to redirect waste particles away from the filter assembly. The low pressure area created by air introduction at this intermediary point serves as a transfer mechanism that moves particles without direct contact with the filter, preventing clogging while maintaining system functionality
2Reliability
If a clarifier zone or settling compartment is added to separate waste particles, then particle removal improves, but system complexity and space requirements increase
Solution Approach 1:
The invention extracts the particle separation function from a dedicated clarifier zone and relocates it to the outlet baffle inlet area. By introducing air directly at the outlet baffle inlet, the system creates a low pressure area that passively redirects particles away from the filter, eliminating the need for a separate clarifier compartment while maintaining particle removal effectiveness
Solution Approach 2:
The outlet baffle inlet serves multiple functions simultaneously: it introduces air for aeration, creates a low pressure area for particle redirection, and acts as a protective barrier for the filter assembly. This multi-functionality eliminates the need for separate clarifier zones, reducing system complexity while maintaining particle removal capability
3Reliability
If the filter is cleaned or replaced frequently to maintain performance, then bacterial contamination is reduced, but maintenance time and system downtime increase
Solution Approach 1:
The invention applies preliminary action by introducing air directly at the outlet baffle inlet before waste particles can reach and clog the filter assembly. The low pressure area created by this preliminary air introduction redirects particles away from the filter in advance, preventing clogging before it occurs and eliminating the need for frequent filter cleaning or replacement

Function Achieved in This Case
This solution enhances septic system productivity by reducing waste particle entry, lowering bacterial and solid discharge, prolonging filter and system life, and eliminating the need for clarifiers, while allowing cleaner effluent to enter the secondary treatment system.
Implementation Method 1
introducing forced air from an air pump directly at the inlet of the outlet baffle or filter assembly
Implementation Method 2
The low pressure area produced by introducing air around and near the inlet of the outlet baffle or filter assembly redirects any waste particles away from the discharge point
Implementation Method 3
introduces forced air into the septic tank through a diffuser system which causes aerobic bacteria to proliferate in the septic tank
Implementation Method 4
aerobic action process

AI summary
An air driven particle recirculator designed to introduce air around a single or multiple compartment septic tank discharge outlet baffle or filter assembly. The air driven particle recirculator causes a movement of waste particles and suspended solids to be forced away from the inlet of the outlet baffle or filter assembly to only allow cleaner filtered effluent to enter the secondary treatment system. The particle recirculator performs a function normally carried out by a settling compartment or clarifier zone associated in aerobic type septic systems. When installed in a single or multiple compartment septic tank utilizing an aerobic process, the particle recirculator will remove waste particles from the discharge area causing cleaner discharge and a cleaner septic tank filter assembly or outlet baffle reducing potential pre-mature failure or damage to the secondary treatment system. The particle recirculator, used in conjunction with an aerobic process, will result in dramatically and lower coliform and E. coli bacteria levels, as well as reduce levels of oil, grease, settable solids and suspended residue.
