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.

Hazardous locations: the game rules – Part 1

This blog article introduces hazardous locations: the classified areas where explosive atmospheres involving flammable gases, vapours or combustible dusts are likely to be present and therefore require measures to prevent ignition hazards. When it comes to hazardous locations, plant managers must exercise judgment based on both risk management principles and the judicious use of financial resources. But how should they base their decisions? How do they ensure they’re implementing the right measures without overdoing it? Since there are several possible approaches, it’s important to be supported by experts to prevent unnecessary concerns and expenses. Where do you stand?

Is SD-WAN for everyone? Almost!

The digital revolution is transforming how we work and communicate. It’s also changing how we connect and manage links between buildings using wide area networks (WANs) and software-defined WANs (SD-WANs). In an SD-WAN, the WAN is defined dynamically by a software layer that sits on top of the standard telecommunications links. But many wonder whether an SD-WAN solution is right for them and whether it will really reduce their connectivity costs. Let’s take a closer look at these questions.

Metal structures near high-voltage power lines: What are the risks?

High-voltage transmission power lines (69 kV and up) are designed to meet numerous performance criteria that, when combined with construction restrictions in the right-of-way, help keep people safe. However, developers of major infrastructure assets, such as pipelines, railways and telecommunications systems, have come under increasing pressure in recent years to use available rights of way. For example, there’s interest in reducing environmental impacts by using available corridors, even though transmission lines already run through them.

Alarm rationalization: a guide for quick wins!

If you type “alarm management” in a search engine, you will get hundreds of results including articles, papers, presentations and guides. Those results may contain some useful information, but in many cases, they deal with the complete process of alarm rationalization. The problem is that not everyone will dedicate the time and resources needed to implement an exhaustive alarm rationalization process that includes a comprehensive audit and the development of an alarm management philosophy document. This blog presents an easy and concrete method for quickly reducing the number of alarms received.
