Selenium Removal Technologies: A Review

Selenium, a contaminant of concern in industries such as mining, oil refining, and power generation, is removed from wastewater principally through either biological or chemical/physical processes. This article will describe those technologies, several technology providers, and other sources of information.

Importance Of Flare Gas Measurement Grows To Meet Environmental Regulations

In the oil and gas industry, regulations and requirements to measure, monitor and report flared gases continue to expand and extend. The U.S. EPA continues to focus on enhancing regulations aimed at reducing emissions of methane and volatile organic compounds (VOCs) into the environment.

Resolving High PH For Mining Operations

For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

Revolutionary Sludge Management Comes To America

Wastewater utilities have a new opportunity to turn their sludge (biosolids) into something special.

99-Percent-Efficient Plant Shows Food, Beverage, And Agribusiness How To Recycle Wastewater And Profit From Green Energy

An outstandingly efficient industrial wastewater treatment plant using technology being introduced to Australasia is demonstrating to the food, beverage, and agribusiness processing industries how to turn waste into profit.

ABB Flowmeters Help Keep Macallan Whisky At Its Peak

Accurate measurement delivered by a range of ABB flowmeters is helping the company behind the world-renowned Macallan whisky brand to maintain its high product quality standards following its move to its new 187.2M USD distillery.   

Distillery Wastewater Byproducts Fuel Sustainability

For distilleries, high levels of biochemical oxygen demand (BOD), nitrogen, total dissolved solids (TDS), and total suspended solids (TSS) put extra pressure on optimal biological treatment requirements. Here are some techniques that can help distillers put a little extra money in the bank while meeting the challenges of environmental discharge requirements.

How To Power Your Treatment Plant And Reduce Costs With Waste-To-Energy Technology

Electricity is a major cost for industry operations, and the cost of meeting environmental regulations is right up there as well. At the same time, industries are compelled to improve sustainability and lower their carbon footprints.

Selenium Removal Technologies: A Review

Selenium, a contaminant of concern in industries such as mining, oil refining, and power generation, is removed from wastewater principally through either biological or chemical/physical processes. This article will describe those technologies, several technology providers, and other sources of information.

Panametrics Water Flow Meters: Boundary Busting Longevity And Quality

Late last millennium, Panametrics installed a model 6068 liquid clamp-on flow meter for the measurement of water in Kinlochleven Hydro Power, a hydroelectric power plant in Scotland, to monitor turbine generator performance.

Filter Installations Remove Solids From FGD Scrubber Effluent

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

Innovative Utilities Reducing Water-Energy Nexus Pressures

With large parts of the country facing drought conditions, including California, Massachusetts, and Alabama, small communities and cities alike are facing increased water-energy nexus pressures.

The Future Of Hydroelectric Power: Balancing Generation With Environmental Impact As global climate goals and the environmental impact of hydroelectric systems draw increased attention, the conversation for energy leaders and water resource professionals has shifted from expansion to optimization, where smarter infrastructure and adaptive strategies must work together to reduce harm without compromising output.

The Challenge Of Tracking Nutrient Pollution 2,300 Miles

Nitrogen and phosphorus are essential nutrients — yet too much of a good thing is not always a good thing. Scientists are investigating nutrient pollution down the Mississippi River.

Water Runs Through The Circular Economy

Circular economy approaches can add value to a vast range of processes and product sectors, but water is the ‘blue thread’ that flows through it all, Nick Jeffries tells Paul O’Callaghan, chief executive, BlueTech Research.

The Improved Business Case For Membranes In Industrial Water Reuse

Membrane filtration can be a valuable tool in industrial operations by removing oils and solids that are generally not captured with other bulk separation methods. However, membranes have traditionally been limited by low throughputs, poor durability, and the inability to consistently achieve low residual oil levels. The good news is advanced membrane filtration technologies that promote efficient and economical water reuse are now available.

Sewer Mining: An Unconventional Solution To Water Scarcity

‘Sewer mining’ may sound like a search for mistakenly flushed and washed-away valuables, but it’s actually a sophisticated, sustainable strategy for combating water scarcity.

Rising Pollution Levels To Offer New Growth Opportunities To The Activated Carbon Fiber Market Share

Rapid industrialization pushed by record population growth and urban migration, in tandem with several other factors such as excessive use of nitrogen-based fertilizers and pesticides, forest fires, residues in agriculture, and improper waste management, has deeply intensified pollution and environmental health risks.

Revolutionary Sludge Management Comes To America

Wastewater utilities have a new opportunity to turn their sludge (biosolids) into something special.

TASKMASTER® Multi-Stage Shredding System for Pharmaceutical Plant Security

A pharmaceutical manufacturer was faced with major waste management concerns. They urgently needed a powerful shredding system capable of quickly and efficiently reducing bulky pharmaceutical rejects, packaging and literature to an unrecognizable condition. The company had recently purchased shredding equipment to replace older units, which were failing, but soon encountered unexpected problems. Pharmaceutical material passing through the carbon steel shredders often contained corrosive chemicals, which eventually eroded the units.
