Solid Dissolver Cartridge for Sewage Decomposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sewage treatment systems face disruptions due to high organic matter content, particularly grease, which clogs collection systems and requires frequent replenishment of supplemental bacteria for effective decomposition, leading to space and logistical challenges.
Innovation Solution
A solid dissolver system with a housing and cartridge containing an inner core of high water-solubility materials and an outer core with a binder matrix, where the inner core dissolves quickly to release agents like oxygen generators, enzymes, and bacteria, followed by a sustained release of outer agents for extended treatment, enhancing decomposition and fluidity in waste water collection systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supplemental bacteria are frequently replenished to maintain decomposition effectiveness, then organic matter decomposition is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent applies preliminary action by pre-loading the cartridge with a substantial quantity of supplemental bacteria and nutrients before installation in the lift station. This allows the bacteria to be released gradually over time without requiring frequent manual replenishment, thus maintaining decomposition effectiveness while reducing operational burden. The cartridge is prepared in advance with all necessary components (bacteria, nutrients, oxygen generators) to sustain treatment for an extended period.
Solution Approach 2:
The system implements self-service through the cartridge design that automatically releases bacteria and nutrients in response to water flow or contact with sewage. The cartridge requires no active control system, pumping mechanism, or monitoring - it simply dissolves and releases its contents when exposed to the sewage environment, eliminating the need for complex operational intervention while maintaining reliable decomposition.
2Reliability
If liquid bacterial compositions are pumped into lift stations, then decomposition is enhanced, but space requirements and dispensing equipment complexity increase
Solution Approach 1:
The patent employs a disposable cartridge that contains pre-measured bacteria and nutrients in a compact solid form. Unlike liquid bacterial compositions that require storage tanks, pumping equipment, and complex dispensing systems, the cartridge is a simple, compact unit that is installed and then discarded after use. This eliminates the need for space-consuming liquid storage and dispensing infrastructure while maintaining decomposition enhancement through controlled bacterial release.
Solution Approach 2:
The system replaces the mechanical pumping and dispensing infrastructure required for liquid bacterial compositions with a passive dissolving cartridge. Instead of using pumps, hoses, and control systems to deliver bacteria, the cartridge relies on natural dissolution and water flow to release its contents, thereby eliminating the need for complex mechanical delivery systems and reducing space requirements.
3Reliability
If bacteria cultures grow on tank surfaces and bottom, then grease decomposition occurs, but treatment coverage and effectiveness are limited
Solution Approach 1:
The patent utilizes hydraulic action by designing the cartridge to release bacteria into the water flow rather than allowing them to settle and grow only on surfaces. As water flows through the lift station, it carries the released bacteria throughout the entire volume of sewage, ensuring comprehensive treatment coverage. This hydraulic distribution method transforms the limited surface-based treatment into a system-wide treatment that addresses grease throughout the entire collection system.

AI summary
A solid dissolver system for the treatment of waste material in a waste water collection system. The solid dissolver system includes a housing. The housing includes a cover and a platform portion for receiving the cover. A cartridge containing agents for the treatment of waste material is disposed within the cover, the cover substantially surrounding and enveloping the cartridge, the cover including an opening. A water inlet is provided into the housing, the water inlet terminating at a spray means disposed proximate to or inside the cover opening, the spray means being capable of directing water at an exposed surface of the cartridge, the platform portion being capable of collecting any effluent from the water directed at the exposed surface of the cartridge by the spray means. A water outlet for channeling the effluent into a waste water collection system is included in the platform portion. The cartridge includes an inner core and an outer portion partially surrounding the inner core such that at least one surface of the inner core is exposed. The inner core has a greater water solubility than the outer portion.
