Basics
- Often Abbreviated as CBAT
- Advanced Treatment of Water (Typically A Secondary/Tertiary Phase of Wastewater Treatment for Blackwater Recycling to Potable Water , although it could also be used at a Water Plant using Rainwater Capture or Riverbank Filtration etc
- Although most systems cannot adjust Salinity / TDS so those cases are better suited to Reverse Osmosis Advanced Treatment
- Although POTENTIALLY CBAT could be used to reduce the Brine to just Salts etc, but this would be the cost of BOTH system, and unless the benefit is major (and/or Reverse Osmosis Brine Disposal is a sufficiently major factor), this solution seems debatable
- Although most systems cannot adjust Salinity / TDS so those cases are better suited to Reverse Osmosis Advanced Treatment
- While the process can use Filtration, Ozonation (Water Treatment) , UVGI (Water Treatment) , and other technologies, in CBAT the MAJORITY of the work is being done by Activated Carbon (typically Granulated Activated Carbon ) and/or Biological Activated Carbon hence the name
Internal Links
- Open Source Modular Carbon Based Advanced Treatment Train
- Due to the use of Appropriate Materials , and the ability to even remove Contaminants of Emerging Concern etc, this technology would be VERY useful if Open Sourced and implemented widely
- With the caveat of it being used AFTER a primary Sedimentation and/or Anaerobic Digestion stage
- Then either use for Irrigation as Reclaimed Water (if use as potable water is too taboo/hard to reach the standard, think Greywater Gardens etc), or ideally as Potable Water
- Advanced Oxidation Processes
- Direct Potable Reuse and Indirect Potable Reuse
External Links
- USA EPA - Overview of Drinking Water Treatment Technologies
- Mentions advantages and disadvantages of many technologies but does mention GAC and Biological Treatment
- A 2013 Paper in “ Biomass Now - Cultivation and Utilization” Titled “Biological Activated Carbon Treatment Process for Advanced Water and Wastewater Treatment”
- An Article by Hazen and Sawyer Titled “ Potable Reuse Is Coming to Your Region. Are You Ready?”
- Note that they do make/sell some of this technology, so there is the bias of “Of course you want OUR TECHNOLOGY” etc…although to be fair…it is a pretty good solution!
- A 1992 Article in “Water Research” Titled “ Biological activated carbon in fluidized bed reactors for the treatment of groundwater contaminated with volatile aromatic hydrocarbons”
- This was moreso in the context of Gasoline Spill / Gasoline Leak Remediation, but worth noting regardless
- The controlled test of Only Microbes, Only GAC, and BA-GAC / BAC, was worth noting
