Treatment and reuse of coalmine wastewater in Vietnam ...

Coalmine wastewater has long been a concern due to its potentially severe adverse environmental impacts, such as soil and water pollution. The wastewaters from coalmines, which are commonly referred to as acid mine drainage (AMD), are formed by the chemical and biochemical reactions in the groundwater exposed to the ore and oxygen.

As ocean pH drops, the aquatic environment could become to ,acidic, for kelp to survive. Human use of rivers and estuarine habitats can also affect kelp forests. As we continue to use rivers for such things as logging, dredging, and development, we dislodge large amounts of sediment into the rivers that is ultimately flushed into the oceans.

The highest efficiency was observed in weak ,acidic, conditions and an increase in salinity enhanced the treatment efficiency significantly. Furthermore, the treatment of highly saline industrial ,wastewater, as well as multi-contaminant groundwater containing persistent organics were also investigated.

Groundwater pollution - Wikipedia
Groundwater pollution - Wikipedia

Groundwater pollution, can be caused by untreated waste discharge leading to diseases like skin lesions, bloody diarrhea and dermatitis. This is more common in locations having limited ,wastewater, treatment infrastructure, or where there are systematic failures of the on-site sewage disposal system.

Groundwater pollution - Wikipedia
Groundwater pollution - Wikipedia

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.

It is speculated, that the aluminum cation is functioning to replace the sodium (or calcium) cation to result in an insoluble aluminum naphthenate precipitate. This method offers an advantage over acidified extraction as a strategy for organic acid removal in that it does not require pH depression.

reaction of Fe2+, organics and PS in ,acidic, solutions. This may dramatically improve the overall removal efficiency of Qu. The results indicated that the initial removal rate of Qu increases from 85.8% to 92.9%. The cleavage pathway of Qu is ,speculated, by Frontier molecular orbital (FMO) theory and verified by GC/ MS analysis. Introduction

1/10/2020, · The high concentration of, contaminants, in the acidic wastewater will lower the produced sulfuric acid quality, and may even lead to the unavailability of this recovered sulfuric acid. For instance, during the production where the recovered diluted sulfuric acid containing Cl(−I) is used as the materials, Cl(−I) impurity may be transferred to the products and greatly lower the quality of products.

30/11/2019, · Municipal ,wastewater, treatment plant, which is a place for antibiotic ,wastewater,-concentrated disposition, cannot completely remove antibiotics by conventional secondary treatment. In this case, the research emphasis of antibiotic ,wastewater, treatment includes the removal efficiency and, at the same time, the cost.
