EVALUATING CRAB-SHELL CHITIN, LACTATE, AND SPENT MUSHROOM COMPOST FOR ACID MINE DRAINAGE REMEDIATION IN CENTRAL PENNSYLVANIA

Evaluating Crab-shell Chitin, Lactate, and Spent Mushroom Compost for Acid Mine Drainage Remediation in Central Pennsylvania

Acid mine drainage (AMD) is a major environmental consequence of mining activity. This is a recurring problem around the world, and especially in some specific areas of United States, including Pennsylvania. Remediation of AMD has three requirements: pH neutralization, reduction of sulfate concentrations, and removal of dissolved metals. The aim of this study was to evaluate the sustainable was...

Efficient metal removal and neutralization of acid mine drainage by crab-shell chitin under batch and continuous-flow conditions.

Crab-shell chitin was evaluated as a multifunctional substrate for treating acid mine drainage (AMD) in both batch-microcosms and continuous-flow column tests. In microcosms, crab-shell chitin was able to treat AMD from three different sites with similar results: pH increased from 3.5 to approximately 7.5 within 2 days; alkalinity increased at a rate of 37.9+/-2.2 mg CaCO(3)/L day; and sulfate ...

Bio-Remediation of Acid Mine Drainage in the Sarcheshmeh Porphyry Copper Mine by Fungi: Batch and Fixed Bed Process

Acid mine drainage (AMD) containing high concentrations of iron and sulphate, low pH and variableconcentrations of heavy metals leads to many environmental problems. The concentrations of Cu and Mnare high in the AMD of the Sarcheshmeh porphyry copper mine, Kerman province, south of Iran. In thisstudy, the bio-remediation of Cu and Mn ions from acid mine drainage was investigated using two nati...

Quality assessment of compost prepared from spent mushroom substrate

The human demand for protein-rich food is everincreasing which contributes to the expansion of mushroom industry in the world. Statistically, the word production of mushroom industry has reached a level greater than 25 million tons (Yang et al., 2015). In spite of many advantages, the production of mushrooms generates large volumes of solid waste products (called spent mushroom substrate) which...
