Mobile Wastewater Purification Filter with Multi-Stage Cartridge System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for cleaning wastewater from building facade treatments, such as sandblasting or high-pressure washing, are cumbersome, require handling of chemicals, and are not mobile, making it difficult to efficiently and safely dispose of wastewater containing paint residues and heavy metals during the cleaning process.
Innovation Solution
A compact filter device with multiple redundant cartridges, including sediment filters and activated carbon filters, that can be easily transported and used on-site, featuring a submersible pump and a system for recycling clear water to reduce fresh water usage and facilitate continuous operation without interrupting work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wastewater treatment systems are used, then wastewater can be purified, but the devices are bulky and not mobile
Solution Approach 1:
The treatment system is divided into separate functional modules: a collection container, a filtration unit with multiple filter stages, and a pump system. This segmentation allows the components to be compactly arranged and easily transported while maintaining effective wastewater treatment capabilities.
2Productivity
If scaffolding is used for facade cleaning, then cleaning work can be performed, but sewage catchers and ducts must be repositioned frequently which is time-consuming
Solution Approach 1:
The system includes a self-contained collection container that accumulates wastewater directly at the cleaning location. The integrated pump automatically transfers wastewater through the filtration system without requiring manual repositioning of sewage ducts, enabling continuous operation throughout the facade cleaning process.
3Ease of manufacture
If untreated wastewater is drained into sewage system or allowed to seep, then disposal is simple, but environmental harm occurs
Solution Approach 1:
The filtration system uses multiple filter stages with different pore sizes and filtration mechanisms tailored to specific contaminants. The first filter captures large particles, the second filter captures finer particles, and the activated carbon filter removes chemical contaminants, ensuring comprehensive purification before discharge.
4Reliability
If multiple filter stages are used, then purification effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple filtration stages are combined into a single integrated filtration unit with sequential filter elements. The collection container, pump system, and multi-stage filters are merged into one compact mobile device, simplifying operation while maintaining effective purification through staged filtration.
