An overlooked nanofluids effect from Fe3O4 nanoparticles enhances mass transfer in anammox granular sludge

Water Research X
Magnetite (Fe3O4) particles have been widely reported to enhance the anammox's activity in anammox granular sludge (AnGS), yet the underlying mechanisms remain unclear.

Anaerobic Treatment of Concentrated Black Water in UASB Reactor at a Short HRT [PDF]

This research describes the feasibility of applying a UASB reactor for the treatment of concentrated black (toilet) water at 25 °C. On average 78% of the influent load of COD at an HRT of 8.7 days was removed. Produced methane can be converted to 56 MJ/p/

The enhancement of anammox by graphene-based and iron-based nanomaterials in performance and mechanisms

npj Clean Water
Anaerobic ammonium oxidation (anammox) is a cost-effective biological nitrogen removal technology, yet its time-consuming start-up and significant environmental sensitivity are major barriers to its widespread use.

Treatability of digested piggery/poultry manure by anammox bacteria [PDF]

, 2014
The liquid fraction of digested material is rich in ammonium and may require nitrogen removal. The aim of this research was to evaluate the applicability of the anammox process for the biological N removal from a supernatant coming from the anaerobic ...
