Microcosm Studies for Neutralization of Hypolimnic Acid ...

Ten microcosms of 0.088 m3 water volume (0.3 m i.d. and 1.20 m height) were designed for neutralization studies representing hypolimnic ecosystem models for ,acid mine, pit lakes. Sediment and water were collected from an ,acid, lignite ,mine, pit lake (Brandenburg, Germany) and filled into the microcosms. To determine the efficacy of controlled in situ organic carbon amendments as a possible ...

A factorial experimental design method was used to examine the "Cu2+" removal ,from acid mine drainage wastewater, by ion exchange technique. Ion Exchange technique is preferred because of reduced sludge generation compared to conventional treatment techniques and better decontamination efficiency from highly diluted solutions. Factorial design of experiments is employed to study the …

The ,limestone neutralization, system is limited by the concentration and the rate of dissolution of carbonate. The solubility product defines that the carbonate dissolution cannot exceed 4.9×10-9 N. Increasing the surface area of ,limestone, can optimize the rate of dissolution; however, it must be ground to a particle size of approximately -200 mesh to be effective.

Abstract Pulsed bed treatment ,of acid, mine drainage (AMD) uses CO2 to accelerate ,limestone, dissolution and intermittent fluidization to abrade and carry away metal hydrolysis products. Tests conducted with a prototype of 60L/min capacity showed effective removal of H+ acidity over the range 196–584mg/L (CaCO3) while concurrently generating surplus ,acid neutralization, capacity.
