Conventional ,wastewater treatment, using activated sludge has been reliably and extensively used to remove organic matter and nutrients from ,wastewater, since its introduction about 100 years ago. However, this ,treatment, technology is energy intense and could be considered unsustainable because of high costs for the oxygen supply and its dependency on a continuous energy supply.

Active treatment systems mix, control and monitor the pH of chemical-bearing wastewater. An active treatment system typically includes a sampling tank and one or more chemical feed tanks. These systems routinely include polypropylene pumps, pipes, fittings and valves, along with alarms and recorders.

Abstract ,Treatment of acid, mine drainage can be accomplished by either ,active, or ,passive treatment, systems. Choice between ,active and passive treatment, and appropriate selection of systems within each category is critical for ,treatment, success. In general, ,active treatment, is more commonly used at operational mines whereas ,passive treatment, is typically considered for closed and abandoned mines.

To avoid this environmental damage, measures must be taken, both preventative (or ,passive,) and ,active, through the implementation of ,treatment, methods for these acidic effluents. In regards to ,treatment, technologies, it is important to note that on numerous occasions a single procedure does not prove sufficient, resulting in the necessity for a combination of various procedures.

Successful mine water treatment systems often involve more than one technology or approach for multiple pollutants. CEC assists clients with determining appropriate treatment technologies by conducting bench-scale and/or pilot-scale tests. CEC offers both active and passive technologies as options for treating mining wastewater.

The first step in the ,acid, mine drainage flowsheet is de-carbonation. In many cases, chemical consumption is the number one operating cost of an ,acid, mine drainage ,treatment, system. As such, it is critical that chemical usage be optimized. Typically, with ,acid, mine water, there is a high amount of CO 2 in the waste stream.
