Basics
- A Modular, Advanced Treatment system for the IBC Tote Biodigester style Anaerobic Digestion system
- Main goals would be:
- Further reducing BCOD and other nutrients in the Anaerobic Digestion Effluent
- Burning up Hydrocarbons and whatever else can be treated with Advanced Oxidation
- Adsorbing what cannot be treated, for proper (centralized) disposal
- IE every so often a Roll Off Box or IBC Tote or Dumpster etc is taken to a centralized incinerator
Needed Modules + Technology Readiness Level of Each
Pre-Screening / Surge Storage
- This might only really be needed at larger scales (and to an extent can be a bit gross), BUT can be useful for keeping everything downstream running well
- To an extent too sealing things up well, Design for Cleaning + Design for Decomissioning etc, and Odor Emissions Control
- The screen takes anything that ISN’T Water, Urine/Feces, and Greywater (So dirt, soapy water, FOG etc), and strains that out
- Ideally either micro- Mechanical Biological Treatment (to make it “composted clean” pre-removal), or something akin to an Incinerator Toilet to turn the NASTY trash into clean/sterile/non-smelly trash would be ideal
- Surge storage may be as simple as additional Conical Tanks or IBC Totes, and these could potentially also be Biodigesters but yeah
- Undeveloped so Technology Readiness Level is pretty low on this
Anaerobic Digestion Pre-Treatment
- Some degree of Sedimentation / Centrifuge Concentration etc may be useful
- While not a requirement, increasing the “Loading Rate” or whatever should increase Gas Production / Efficiency of the Biodigester etc
- Granted Citation Needed
- Also Ideal Loading of an IBC Totes style Biodigester may still be unknown/not studied yet
- ALSO certain large scale AD or plants do something akin to Pasturization (which can help keep the microbes in the biodigester what you want, and also may make a sort of Lysomy Broth type mix
- You can also make various nutrients more broken down/bioavailable with some of these pretreatments
- If the complexity is worth it is the main question
- Pre-Ozonation can MAYBE be done as well depending on how things go
- Low Technology Readiness Level; but due to there being less messing around with the Solid Waste Streams and moreso just plumbing/heat exchangers etc it is a BIT more “lego like”
- Still expect unforseeen issues/integration hell and all that though
Anaerobic Digestion
- Re: Biodigester / Biodigester Genealogy
- Already Built
- Uncertain on how many Months/Years in Active Use
- Also some potential for improvement in:
- Main uncertainty is if it eventually gets clogged up with Grit (Wastewater Treatment) / Precipitated Digestate etc, and what all goes into UN-clogging it.
- That and eventual cleaning+disassembly for either HEAVY rework (such as replacement of a dry rotted IBC Tote), or removal/replacement.
