Passive treatment of acid mine drainage water: a sustainable solution

Acid mine drainage (AMD) is a persistent environmental challenge. It occurs when sulfide minerals, exposed to air and water during mining, break down and produce acidic, metal-laden water. This contaminated water harms ecosystems, pollutes water sources and in general creates challenges for mining operations. Traditional treatment methods (active treatment technologies) can address AMD but are often costly and energy-intensive. On the other hand, passive treatment systems rely on natural biological, chemical and physical processes to treat AMD. These systems provide a more environmentally sustainable and efficient solution under the right conditions. This article explores passive treatment systems, including their types and longevity, highlighting their potential as a long-term environmental remediation approach.

When is voltage safe?

An electric shock can affect the person who receives it in a variety of ways, and these effects may not be visible or immediate. In a work setting involving 60 Hz of alternating current (AC) power, the intensity of the current flowing through the body is often assessed using the threshold of sensation (about 1 mA), the threshold of muscle contraction preventing relaxation (about 6-24 mA) and the threshold of cardiac arrest that can lead to death (about 50-100 mA).

Migrating a distributed control system: modernizing industrial controllers and I/O boards

In a previous blog article, we discussed the challenges and technologies to use when carrying out a major upgrade of human-machine interfaces (HMIs) for a distributed control system (DCS). In this last of three blog articles, we’re topping off our series with the second phase of migrating a DCS: upgrading industrial controllers and input/output (I/O) boards.
