Thermophilic and mesophilic temperature phase anaerobic codigestion (TPAcD) compared with single-stage co-digestion of sewage sludge and sugar beet pulp lixiviation [PDF]
, 2016 The performance of temperature phase anaerobic co-digestion (TPAcD) for sewage sludge and sugar beet pulp lixiviation (using the process of exchanging the digesting substrate between spatially separated thermophilic and mesophilic digesters) was tested

Physicochemical Processes of Metal Lixiviation in the Disintegrator [PDF]
IOP Conference Series: Materials Science and Engineering, 2016 The results of lixiviation-based recycling of ore mill tailings in the high-speed disintegrator are presented. The regularities of the change in properties are defined, as well as control directions over them via alteration of variable processing factors are defined.

Lixiviation multi-échelles de cendres d'incinération d'ordures ménagères [PDF]
Environnement, Ingénierie & Développement, 2006 Predicting the impact on the subsurface and groundwater, of a pollutant source such as domestic waste incineration residues, requires a knowledge of the so-called “source term”. The source term describes the manner in which concentrations in dissolved elements emitted by the waste evolve over time, for a given percolation scenario.

A protocol for lixiviation of micronized plastics for aquatic toxicity testing
Chemosphere, 2023 Plastics contain various types and amounts of additives that can leach into the water column when entering aquatic ecosystems. Some leached plastic additives are hazardous to marine biota at environmentally relevant concentrations. Disparate methodological approaches have been adopted for toxicity testing of plastic leachates, making comparison ...

Filtering the unfilterable: tuning the mesostructure of precipitating silica gels to improve the filterability of acidic lixiviation slurries [PDF]
Comptes Rendus. ChimieSilica precipitation is a ubiquitous but deleterious phenomenon occurring in many hydrometallurgical processes. Indeed, silicon is often released during the dissolution of minerals under acidic leaching conditions. Eventually, it precipitates into a hard-

Épandage d’effluents agro-industriels et risque de lixiviation
, 2017 L’épuration des effluents d’industries agroalimentaires (IAA), en Champagne – Ardenne notamment, est assurée majoritairement à travers l’épandage des effluents bruts sur les sols agricoles. Néanmoins, il est nécessaire de s’assurer de la compatibilité environnementale de cette technique avec la préservation de la qualité des eaux souterraines.
