When the vapor flow in a distillation column drops too low, liquid leaks through tray perforations instead of flowing across the tray surface. This phenomenon, called distillation column weeping, can undermine mass transfer efficiency and overall separation performance. Recognizing the warning signs and addressing root causes restores optimal performance. What Causes Weeping in a Distillation […]

Discover a multi-layered defense for total odor management that neutralizes odors rather than just capturing them. While various odor control methods exist, the most robust strategies use a primary workhorse technology supported by secondary systems to effectively and efficiently control odor in wastewater treatment plants. Building a Multi-Layered Defense Against Odor Managing odors may be […]

Coal scrubbers act as environmental filters in power plants. These devices use chemical reactions to neutralize sulfur dioxide (SO₂), turning it into manageable by-products. Environmental regulations are continuing to tighten, making coal scrubbers a vital tool for regulatory compliance. Sulfur dioxide remains one of the most prevalent, harmful pollutants released during coal combustion. Without effective […]

For any industrial facility, maintaining operations requires a careful balance of productivity, profitability and responsibility. A critical component of this responsibility is ensuring environmental compliance. Adhering to air quality regulations is a fundamental requirement for doing business. Government bodies, guided by regulations like the Clean Air Act, set enforceable limits on emissions to safeguard public […]

Wastewater entering the wastewater treatment plant (WWTP) often contains a range of volatile contaminants, such as volatile organic compounds (VOCs), ammonia and odor-causing compounds. Effectively removing these challenging compounds is critical for ensuring environmental compliance and achieving the highest possible quality for treated wastewater. How Wastewater Treatment Plants Improve Water Quality To effectively manage volatile contaminants, […]

Mist eliminators provide a critical function in industrial processes. Most industrial processes involving gas-liquid contact rely on mist eliminators to remove trapped liquid droplets from vapor streams. Two main designs dominate the market: wire mesh and chevron mist eliminators. Grasping the differences between these technologies allows operators to select the right solution for a specific […]

Despite the control measures and regulations in place, industrial water pollution is still a problem in the United States. The Environmental Protection Agency (EPA) has found that thousands of businesses have polluted water bodies to unacceptable levels. To help your facility comply with key water pollution standards, MACH Engineering has written this useful guide on water pollution […]

Meeting discharge permits while minimizing energy costs can be challenging. Air strippers can effectively remove volatile contaminants and certain dissolved gases, helping your business meet regulatory limits for wastewater stripping and discharge. This guide to air stripping explores the process and covers the key design factors. What Is Air Stripping and Why It Matters Air […]

The modern world relies on industrial businesses. However, the industry results in air pollution that negatively impacts economies. Controlling this pollution protects workers, businesses and communities. It reduces long-term consequences, such as chronic health issues, productivity losses and business shutdowns. Certain businesses are already making operational changes to mitigate damage from greenhouse gas (GHG) emissions. […]

For years, it’s been widely known that industrial air emissions pose an environmental hazard. But what is less discussed is how these emissions can negatively impact our health. The damage doesn’t stop there — it can also affect the business’s staff, costs and potential revenue. How do you know if your factory is making people […]
