Bench Prototype¶
The bench prototype is the fastest way to validate the OpenSling treatment logic before committing to a field-ready chassis.
Objective¶
Build a reconfigurable loop that allows quick changes to:
- intake geometry
- solids removal stage
- cartridge selection
- pressure instrumentation
- disinfection method
Suggested Starter Stack¶
| Stage | Example approach |
|---|---|
| Feed | open test reservoir with screened pickup |
| Pump | 12 VDC diaphragm or centrifugal pump sized for moderate flow |
| Pre-separation | small settling chamber or cyclone test section |
| Fine filtration | clear-housing sediment cartridge |
| Polishing | optional carbon block in bypass or full-flow mode |
| Disinfection | UV chamber or placeholder spool for later comparison |
Build Priorities¶
- mount gauges before and after fine filtration
- include sample valves at inlet, post-filtration, and final outlet
- make drains easy to use without spraying the work area
- label flow direction on every removable module
Bench Success Criteria¶
- repeatable flow measurement
- visible and measurable change across at least one treatment stage
- easy cartridge or module swap within minutes
- logging or manual recording procedure defined before the first test
Notes¶
This prototype is for process development. If the system is later aimed at potable use, validation requirements become much stricter than "it looked better on the bench."
