Removal of Organic micropollutants (OMPs) with Subsurface Iron Removal (SIR)

This research explores the potential effect of Subsurface Iron removal (SIR) on the removal of organic micropollutants (OMPs). The presence of OMPs and their transformation products in the water environments globally, have raised concerns due to the potential environmental and human health risks they are posing. Recent technologies often fail to...

Combined nitrogen and aniline removal from hyper-saline industrial wastewater

In the treatment of industrial wastewater, the biological removal of aniline &amp; nitrogen often occurs simultaneously within the hyper-saline water matrix. This study focuses on pioneering the research<br/>on combined aniline-nitrogen removal in a hyper-saline environment. The experimental approach assessed the cause of nitrite accumulation...

Genomic profiles and removal mechanisms explain the observed stratification of Fe²⁺, NH₄⁺ and Mn²⁺ removal in rapid sand filters

Groundwater is an excellent source for the production of drinking water due to its low concentration of microorganisms and contaminants. The main contaminants present in groundwater are iron, ammonium and manganese, which are sequentially removed in rapid sand filters by a combination of biological and chemical processes. Currently, limited...

The quest for specialist N2O-respiring bacteria

Nitrous oxide (N2O) is a potent greenhouse gas, and its stratospheric concentration is already 20% above the pre-industrial level. Over 70% of N2O is produced by microbial processes. Nitrous oxide reductase is the only enzyme able to reduce N2O to innocuous N2. The high abundance of organisms harbouring it and lacking the genetic potential to...
