Activated Sludge Waste Filtration With Multi-Size Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste separating systems for activated sludge treatment facilities require multiple pieces of equipment, increasing costs, area, and operational complexity.
Innovation Solution
A waste separating system comprising a first waste separating apparatus with a first filter and a second waste separating apparatus with a second filter of larger opening size, disposed downstream, allowing the second apparatus to contribute only during increased water flow, thereby reducing equipment needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple filters with different opening sizes are arranged in series to remove waste more effectively, then waste separation effectiveness is improved, but the number of equipment pieces increases
Solution Approach 1:
The downstream waste separating apparatus with larger opening size is designed to serve dual functions: processing overflow water from the upstream apparatus and serving as a backup during maintenance or failures of the upstream apparatus. This multi-functionality allows one piece of equipment to fulfill multiple roles, reducing the total number of equipment pieces needed while maintaining effective waste separation across different flow conditions.
2Productivity
If multiple waste separating apparatuses are installed to handle increased water flow, then waste separation coverage is improved, but the area required increases
Solution Approach 1:
The downstream waste separating apparatus is configured to handle both overflow water from the upstream apparatus and increased water flow conditions. By designing this single apparatus with larger opening size to serve multiple purposes, the system achieves comprehensive waste separation coverage without requiring separate dedicated equipment for each function, thereby reducing the total area required.
3Reliability
If multiple waste treating apparatuses are installed for each filter, then waste treatment capability is improved, but operational costs increase
Solution Approach 1:
The patent merges the waste treatment functions for both the upstream and downstream waste separating apparatuses into a single shared waste treating apparatus. This downstream apparatus collects and treats waste from both upstream and downstream sources, consolidating what would otherwise require separate treatment systems. This merging reduces the number of waste treating apparatuses needed and lowers operational costs while maintaining comprehensive waste treatment capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the number of equipment pieces, area, and operational costs by allowing the second waste separating apparatus to operate at a reduced scale, contributing only when necessary.
Implementation Method 1
a first waste separating apparatus and a second waste separating apparatus each configured to separate waste from treatment target water, the first waste separating apparatus including a first filter with a first opening size
Implementation Method 2
the second waste separating apparatus including a second filter with a second opening size larger than the first opening size and disposed downstream of the first waste separating apparatus
