Abstract Sulphate (SO 4 2-) concentrations in freshwaters have increased globally over the
last decades even though a strong reduction in atmospheric sulphur (S) deposition has …

Abstract Treatment of waters contaminated with sulfur containing compounds (S) resulting
from seawater intrusion, the use of seawater (eg seawater flushing, cooling) and industrial …

Chicken manure, dairy manure and sawdust were evaluated as carbon sources in
promoting sulfate reduction, and the mechanism of heavy metals removal in sulfidogenic …

Biochemical passive treatment represents a promising option for the remediation of acid
mine drainage. This study determined the effect of three hydraulic retention times (1, 2, and …

Passive systems are an effective and promising technology for treatment of moderately-
contaminated mine drainage (MD) under temperate and/or semi-arid climates. However …

Pilot-scale field-testing of passive bioreactors was performed to evaluate the efficiency of a
mixture of four substrates (cow manure compost, mushroom compost, sawdust, and rice …

After the closure of the Yudong coal mine, the pH value was approximately 3.0, and the Fe
and Mn concentrations reached 380 and 69 mg/L, respectively, in the acid mine drainage …

Passive biochemical reactors (PBRs) represent a promising option for the treatment of mine
drainage. In this study, the influence of temperature (22 and 5° C), salinity (0 and 20 g/L) and …

Optimization of the hydraulic properties of reactive mixtures in passive systems can improve
treatment efficiency of iron-rich acid mine drainage (Fe-rich AMD). The use of highly …

The objective of this study was to evaluate the effects of different reactive mixtures and
hydraulic retention times (HRTs) on hydraulic parameters (hydraulic conductivity, k sat, and …
