Anaerobic biological treatment of acid mine drainage from abandoned mines using SRB has shown nearly 99.2% effective removal of copper, zinc, and nickel (Sierra-Alvarez et al. 2006). The use of suspended biological methods for bioremediation of wastewater and resources recovery is an eco-friendly and cost-efficient way.

Seawater is often used as a base ,fluid, to make hydraulic ,fracturing, fluids in offshore HF operations, whereas freshwater is most commonly used in terrestrial HF wells. The injected chemical additives (e.g., stabilizers) therefore also differ due to the use of seawater-based hydraulic ,fracturing, fluids as well as other constraints specific to offshore platforms.

1/11/2020, · The ,treatment of acid mine wastewater, containing Fe(II) and Mn(II) has been a hot topic in a long time. This paper studied the ,treatment of acid mine wastewater, by the electro-Fenton process. First, the effect of key parameters including initial current intensity (50−300 mA), plate spacing (0.5–3.0 cm), and initial pH (3.0–5.0), aeration rate (0−200 mL/min) were studied.

Some drilling operators elect to re-use a portion of the wastewater to replace and/or supplement fresh water in formulating ,fracturing fluid, for a future well or re-,fracturing, the same well. Re-use of shale gas wastewater is, in part, dependent on the levels of pollutants in the wastewater and the proximity of other ,fracturing, sites that might re-use the wastewater.
