Wastewater Separation Trough for Solid Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional separation systems for wastewater face challenges in efficiently retaining solids, particularly during heavy rain events, leading to overflow and contamination of receiving waters due to the accumulation and sudden discharge of solids, which can overload sewage treatment plants and clog pumping systems.
Innovation Solution
A separation system with a collecting trough and a cleaning tool, such as a slide with cleaning elements like a cleaning strip and brush, that removes and transports solids from the separation surface to the collecting trough, where they can be flushed or pumped away, reducing the burden on downstream treatment plants and preventing re-deposition of solids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solids are pushed back into the wastewater inlet during cleaning, then the separation surface is cleared, but the solids concentration in the inlet increases causing overload and clogging
Solution Approach 1:
The patent extracts the separated solids from the wastewater inlet by collecting them in a dedicated collection trough, preventing their re-introduction into the system. The cleaning tool conveys solids directly to the trough where they are removed from the flow path, solving the contradiction between clearing the separation surface and maintaining low solids concentration in the inlet.
Solution Approach 2:
The collection trough acts as an intermediary component between the separation surface and the wastewater outlet. It receives and holds the cleaned solids, serving as a buffer that prevents direct re-introduction of solids into the wastewater flow, thus resolving the conflict between surface clearance and solids concentration control.
2Quantity of substance
If a collection trough is added to collect removed material, then solids concentration in inlet is reduced, but device complexity increases
Solution Approach 1:
The collection trough is merged with the existing separation plant structure, utilizing the same space and integrating with the overflow weir and outlet components. This consolidation approach adds the solids collection function without proportionally increasing overall system complexity, as the trough shares the structural framework with other system components.
