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.

Wastewater Treatment In Oil Refineries

Refineries are among the major consumers of water that has both process and non-process origins. The average refinery requires 2.5 gallons of water for every gallon of crude oil processed. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater varies widely. The design and operation of modern refinery wastewater treatment plants are challenging and are driven by technology. This article will highlight the most common types of waste streams in a refinery and suitable wastewater treatment strategies.

Real-Time Water Quality Data For Industrial Operations

We arm plant operators with actionable data necessary to make informed decisions about water management in industrial facilities.

Use Of Pure Oxygen To Resolve Capacity And Odor Problems

The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

Dechlorination For The Food & Beverage Industry

For food & beverage manufacturers, product safety is paramount. Minimizing water consumption and improving product ratio & energy savings, which reduce carbon footprint, are also key goals of sustainable F&B operation.

Engineering Solutions To Global Water Scarcity

Co-Digesting Food Waste With Wastewater Solids To Produce Energy

Inspired in part by California’s Senate Bill 1383, which was enacted to reduce organic waste and methane emissions, co-digestion is fulfilling those goals while converting wastewater treatment plants into water resource recovery facilities.

Arsenic Contamination Of Food And Water Is A Global Public Health Concern — Researchers Are Studying How It Causes Cancer

Arsenic is a naturally occurring element found in the Earth’s crust. Exposure to arsenic, often through contaminated food and water, is associated with various negative health effects. We study it can lead to cancer through the formation of cancer stem cells.

Water-As-A-Fuel Market For The Future Of Clean Energy

The idea of utilizing water as a fuel source has been speculated by scientists, innovators, and researchers from all over the globe, envisioning a world where renewable, green energy can power the planet.

Design And Care Of Reverse Osmosis Systems, Part 3: Operation And Monitoring

Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.

Relieving The Pressure Of Monitoring Peak Boiler Water Efficiency

Industrial operations across the gamut leverage boiler water, the liquid that passes through a boiler and is converted into steam, thus powering operations around the world. But not all of them do as much as they could to ensure peak boiler water efficiency. Through the proper treatment considerations and quality measurement knowledge, every industrial player can make the most of this central process.

EPA Providing Guidance For Drinking Water After Radiological Emergency

What would happen if there was an emergency in the U.S. that caused radioactive material to contaminate drinking water supplies? What steps could your utilities and government take?

Industrial Water Treatment For Inorganic Contaminants: Biological Treatment Processes

This article is the fifth in a series on industrial water treatment focusing on inorganic contaminants. While regulatory limits are being established, the process of identifying a cost-effective treatment process should be undertaken. Potential water treatment processes for inorganic contaminants can be grouped into three categories: physical, chemical, and biological. This article will describe the biological treatment technologies that may be considered.

Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

ArxZyme™ Acetone Removal For AMPAC Fine Chemicals

AMPAC faced a critical challenge with acetone management. The high acetone levels in the effluent from its chemical processing operations required an effective industrial wastewater treatment solution to meet environmental regulations and ensure safe discharge.

Nutrient Sensor Action Challenge Winners: Data And Decisions To Manage Excess Nutrients

Nutrients in the environment from excess nitrogen and phosphorous can result in negative impacts on water quality. EPA is improving nutrient management by incentivizing the development of low-cost technology solutions, such as nutrient sensors, in collaboration with USGS, USDA, NIST, NOAA, and the U.S. Integrated Ocean Observing System (IOOS).

Clamp-On Flow Meters From Siemens Help To Regulate Outflow From A Dam

A utility company in the Pacific Northwest region of the United States needed to regulate the outflow of a large dam built in the 1930s. The outflow of the dam feeds a river into which the state government wanted to reintroduce a salmon run. Because of this, the utility company would need to comply with some very restrictive limits on how quickly they could change the level of the river. They were now required to account for all water flowing downhill from the dam.
