About 50 percent of the nation’s residents source their fresh water supply from groundwater wells, which have deteriorated throughout the U.S. over the past decade. For shallow wells, severe drought conditions have gradually depleted groundwater levels.

Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of chemical processes. The central refining process is atmospheric distillation whereby the crude oil is fractured into different components based on their differing boiling points. Each of these fractions will be sent along to separate process to be turned into the different oil products. Therefore, remediation of refinery wastewater from these different processes can be quite complex.

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.

This 24″ PIPELINE DELUMPER® was design to handle 84,000 lbs/hr of polypropylene for a major petro-chemical company. The unit features 24 inch inlet and outlet flanges, stainless steel construction and a 50 HP motor to handle oversized agglomerates of polypropylene. The unit de-agglomerates troublesome scale and lumps that can cause operational difficulties for a petro-chemical plant. Reliability is critical as the unit is to be installed extremely high up in a relatively inaccessable area.

IDE recently hosted exclusive guided tours of its horizontal falling film evaporator for SAGD water treatment at the fabrication shop in Calgary, Alberta. Over three days more than 120 industry professionals had the opportunity to experience IDE's SAGD Horizontal Evaporator first hand.

When the Pasteurization Technology Group (PTG) first presented their heat-based wastewater disinfection system to a group of environmental engineers, they didn’t get the response they expected.

Newly discovered electrogenic organisms could significantly reduce energy costs for the wastewater industry.

Water companies are prioritizing engagement with the hospitality sector in their drive to keep sewers free of fats, oils and grease (FOG). Network protection managers at Southern Water and United Utilities, Stephen Williams and Andrew Peet, tell Laura Su, managing director of the European FOG Summit, why cross-sector partnerships must be forged.

Read about the cloth media filter installations that have been operating in food and beverage wastewater plants for over 25 years.

A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O₂, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O₂ to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.

A power plant's wastewater was being contaminated by coal ash generated from power plant operations. The plant was searching for a treatment/polishing system to maintain a TSS of less than 25 PPM. 

Reverse osmosis (RO) pre-treatment is used in industrial water filtration to protect the RO membranes, high pressure pumps and other hardware. The performance of pre-filters matters and can impact your operation, in terms of efficiency and water quality.

The power sector looks to zero liquid discharge and taps municipal reclaimed water as a water reuse strategy.

It’s no wonder that the word "radioactive" scares people. I remember Chernobyl. I was raised on The Simpsons, with its bumbling plant operators and three-eyed fish. I've followed the Fukushima tragedy closely. But, scary or not, nuclear power isn't going anywhere soon.

Since EPA released its proposed Clean Power Plan (CPP) in June of this year, the plan has been a hot topic in every state.

The United States commercial water treatment market was valued at over $5.0 billion in 2021 and is expected to witness a compound annual growth rate (CAGR) of between 5.0 to 10.0 percent over the next 7 years. Key players in this market include Culligan International Co., Ecolab, Inc., Evoqua Water Technologies Corp., and Pentair Industries, Inc.

Coking wastewater generated from the processes of coking, coke gas purification, and recovery of coking products, is highly toxic and carcinogenic. The wastewater usually contains phenolic, aromatic, heterocyclic, and polycyclic organics, and some inorganics, such as cyanides, sulfides, ammonium, ammonia, and so on, which makes it hardly degradable.

As the phrase "forever chemicals" enters the Oxford English Dictionary for the first time in 2024, and these fluorinated substances expand the list of micropollutants, it might be time for a change in the way these persistent environmental pollutants are tackled.
