Reclamation Pre-Filter
Multi-Stage Coarse + Activated-Carbon Pre-Filter for Reclaim Streams
The reclamation pre-filter is an unpowered, three-kilogram filtration unit housed in 316L stainless steel that treats habitat condensate and grey water prior to merging with the main purification chain. Utilizing a modular cartridge stack of pleated polypropylene and activated carbon, the assembly removes particulates down to 10 micrometers while adsorbing organics and odors that would otherwise foul downstream reverse-osmosis membranes. Integrated differential-pressure monitoring triggers cartridge replacement every six to twelve months, sustaining continuous water processing with an 80,000-hour mean time between failures before spent media is transferred to waste management.
Multi-stage filter (coarse + activated carbon) preparing reclaim streams (condensate, grey water) for merge with main purification chain.
Purpose
Multi-stage filter (coarse + activated carbon) preparing reclaim streams (condensate, grey water) for merge with main purification chain.
Context
Child of L2-WTR-RECL in L1-WTR water processing chain
Principles
- ▸Coarse filter (10 um) removes particulates
- ▸Activated carbon removes organics + odor
- ▸Modular cartridge stack
- ▸Differential-pressure monitor triggers replacement
- ▸Bypass during reclaim outage
Typical implementations
- ▸ISS WPA multi-filtration assembly (MFA)
- ▸Industrial pre-filtration cartridges
- ▸POU water filters (residential terrestrial)
Lunar considerations
- ▸Activated carbon binds organics that would foul downstream RO
- ▸L1-MNT cartridge replacement every 6-12 months
- ▸Spent cartridges to L1-WMS
