Burial of microplastics in freshwater sediments facilitated by iron-organo flocs.
Leiser R, Schumann M, Dadi T, Wendt-Potthoff K. Leiser R, et al. Sci Rep. 2021 Dec 15;11(1):24072. doi: 10.1038/s41598-021-02748-4. Sci Rep. 2021. PMID: 34911988 Free PMC article.
We demonstrate how aggregation-based transport facilitates the sinking and infiltration of buoyant microplastics into freshwater reservoir sediments by employing experiments with intact sediment cores. Buoyant polyethylene microplastics were rapidly (1-4 h) incorporated in …

Strength of natural soil flocs.
Kobayashi M. Kobayashi M. Water Res. 2005 Sep;39(14):3273-8. doi: 10.1016/j.watres.2005.05.037. Water Res. 2005. PMID: 16009394
Obtained floc strengths were 0.3, 0.7 and 4 nN for Na-, Ca-, and H-coagulated flocs, respectively. Also, floc strength did not change with floc size. These values of floc strengths were 1-3 orders smaller than those of flocs formed with polymer flocculants an …

He Z, Chang J, Feng Y, Wang S, Yuan Q, Liang D, Liu J, Li N. He Z, et al. Sci Total Environ. 2022 Oct 20;844:157060. doi: 10.1016/j.scitotenv.2022.157060. Epub 2022 Jun 30. Sci Total Environ. 2022. PMID: 35780876
The enhancement of vivianite production after CNTs adding reached up to 17 % by promoting the electron transfer between dissimilative iron-reducing bacteria (DIRB) and Fe(III). However, at the initial stage (0-24 h), Fe(III) reduction efficiency decreased by 81 % after ino …

Syntrophy via Interspecies H2 Transfer between Christensenella and Methanobrevibacter Underlies Their Global Cooccurrence in the Human Gut.
Ruaud A, Esquivel-Elizondo S, de la Cuesta-Zuluaga J, Waters JL, Angenent LT, Youngblut ND, Ley RE. Ruaud A, et al. mBio. 2020 Feb 4;11(1):e03235-19. doi: 10.1128/mBio.03235-19. mBio. 2020. PMID: 32019803 Free PMC article.
Christensenella minuta forms flocs colonized by M. smithii even when H(2) is in excess. In culture with C. minuta, H(2) consumption by M. smithii shifts the metabolic output of C. minuta's fermentation toward acetate rather than butyrate. ...We also demonstra …

Development of a helical coagulation reactor for harvesting microalgae.
Zhang H, Liu C, Ou Y, Chen T, Yang L, Hu Z. Zhang H, et al. J Biosci Bioeng. 2019 Apr;127(4):447-450. doi: 10.1016/j.jbiosc.2018.09.012. Epub 2018 Oct 13. J Biosci Bioeng. 2019. PMID: 30327167
When the Reynolds number closed to the transition between laminar and turbulent flow (4000), the flocs settled faster (20.51 m h(-1)), although settling slowed as the Reynolds number increased further because of ruptured flocs. The settling rate of flocs …

Revisiting Coiled Flocculator Performance for Particle Aggregation.
Carissimi E, Sanagiotto DG, Schettini EBC, Rubio J. Carissimi E, et al. Water Environ Res. 2018 Apr 1;90(4):322-328. doi: 10.2175/106143017X14902968254935. Epub 2017 Sep 8. Water Environ Res. 2018. PMID: 28886755
Results showed that the differences in the flocculator design influences the Fe(OH)3 flocs size and settling rates, reaching values of about 13 and 4 m/h, for the coiled and straight pipes respectively. Coal flocs generation was also shown to be dependent on …
