pH-based control of NH4+ and Mn2+ oxidation sequence in low-oxygen groundwater filters

Emiel Kruisdijk, Francesc Corbera-Rubio, Simon Müller, Frank Schoonenberg et autres

Iron (Fe 2+ ), manganese (Mn 2+ ), and ammonium (NH 4 + ) are the three most common contaminants in anaerobic groundwater and are typically removed in rapid sand filters in a series of simultaneous, uncontrolled, and interconnected redox reactions. In …

Selective enrichment of high-affinity clade II N2O-reducers in a mixed culture

Michele Laureni, Francesc Corbera-Rubio, DaeHyun Daniel Kim, Savanna Browne et autres

Abstract Microorganisms encoding for the N2O reductase (NosZ) are the only known biological sink of the potent greenhouse gas N2O and are central to global N2O mitigation efforts. Clade II NosZ populations are of particular biotechnological interest as they usually feature high …

A biotechnological perspective on sand filtration for drinking water production

Francesc Corbera-Rubio, Roos Goedhart, Michele Laureni, Mark C.M. van Loosdrecht et autres

Gravity-driven sand filters are the dominant groundwater treatment technology for drinking water production. In the past, physicochemical reactions were often assumed to play the main role in the removal of contaminants, but recent breakthroughs showcase the vital role of microorganisms. In this …

Shifting to biology promotes highly efficient iron removal in groundwater filters

Simon Müller, Francesc Corbera-Rubio, F. Schoonenberg Kegel, Michele Laureni et autres

Rapid sand filters are established and widely applied technologies for groundwater treatment. In these filters, main groundwater contaminants such as iron, manganese, and ammonium are oxidized and removed. Conventionally, intensive aeration is employed to provide oxygen for these redox reactions. While effective, …

A difficult coexistence: Resolving the iron-induced nitrification delay in groundwater filters

Francesc Corbera-Rubio, Emiel Kruisdijk, Sofia Malheiro, Manon Leblond et autres

Rapid sand filters (RSF) are an established and widely applied technology for the removal of dissolved iron (Fe2+) and ammonium (NH4+) among other contaminants in groundwater treatment. Most often, biological NH4+oxidation is spatially delayed and starts only upon complete Fe2+ depletion. However, …

Abstract Rapid sand filters are established and widely applied technologies for groundwater treatment. Conventionally, intensive aeration is employed to provide oxygen for the oxidation and removal of the main groundwater contaminants. While effective, intensive aeration promotes flocculent iron removal, which results in …

“Candidatus Siderophilus nitratireducens”: a putative nap-dependent nitrate-reducing iron oxidizer within the new order Siderophiliales

Francesc Corbera-Rubio, Gerben Roelandt Stouten, Jantinus H. Bruins, Simon F. Dost et autres

Abstract Nitrate leaching from agricultural soils is increasingly found in groundwater, a primary source of drinking water worldwide. This nitrate influx can potentially stimulate the biological oxidation of iron in anoxic groundwater reservoirs. Nitrate-dependent iron-oxidizing (NDFO) bacteria have been extensively studied in …
