Climate adaptation and resilience of biofiltration as a low-cost technological solution for water treatment – A critical review

open access: yesCleaner Water
The water supply and sanitation sector has become vulnerable due to extreme weather events such as flooding, wildfires, and droughts. Following wildfires, the erosion of ashes and unburnt carbon into surface water bodies results in higher turbidity and ...

Substrate Pre-loading Influences Initial Colonization of GAC Biofilter Biofilms

open access: yesFrontiers in Microbiology, 2021
Microbial community composition and stability affect pollutant removal for biological/granular activated carbon (BAC/GAC) processes. Here, we pre-loaded the organic carbon substrates sucrose, lactose, and Lysogeny Broth (LB) medium onto new GAC prior to ...

Non-conventional gas phase remediation of volatile halogenated compounds by dehydrated bacteria [PDF]

open access: yes, 2009
Traditional biological removal processes are limited by the low solubility of halogenated compounds in aqueous media. A new technology appears very suitable for the remediation of these volatile organic compounds (VOCs). Solid/gas bio-catalysis applied

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

open access: yesEcography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.
