Treatment Of Produced Water By Electrocoagulation

Produced water (PW) is salty water trapped in the reservoir rock and brought up along with oil or gas during production. It subsists under high pressures and temperatures, and usually contains hydrocarbons and metals. Therefore, it must be treated before being discharged to surface water. Different techniques are being used to treat PW through phase separations, system control and design, and chemical treatments. In this paper, we discuss our experimental results on treating PW through electrocoagulation (EC).

Refinery Wastewater: Benefits Of Remediation By Electrocoagulation

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.

Validating Your Ballast Water Management System

Bio-UV, a manufacturer of ballast water management systems (BWMS) that utilize UV disinfection, was looking for a reliable and accurate indicative analysis to validate the installation of their BWMS system during commissioning. Read the full case study to learn more.

The Changing Role Of Infrastructure Within The Oil And Gas Industry

The drop in price of a barrel of oil has had an understandable impact on major projects in the oil and gas industry. Three years ago, with crude trading above $100 a barrel, schedule was the overriding priority. As time delays were equated to lost revenue opportunity, there was less attention paid to the ultimate cost efficiency of a major project.

State Leaders Concerned About Safety Of Reusing Oil And Gas Wastewater

Regulators from across the country met in Vermont this week at the Environmental Council of the State’s (ECOS) fall meeting to discuss some of the nation’s most pressing environmental challenges. I joined members of ECOS’ Shale Gas Caucus to discuss an emerging threat imminently impacting oil and gas-producing states: the question of what to do with the massive amount of wastewater produced by the oil and gas industry each year.

When Beer Becomes Hazardous Waste

Faced with restaurants and bars suddenly closed for the foreseeable future due to COVID-19, a beverage distributor was forced to take back 40,000 gallons of expired beer. 

The Value Independent Certification Brings To Global Water Stewardship

Every year, World Water Week, a conference organized by the Stockholm International Water Institute(SIWI), brings together experts from around the world to discuss global water issues. This year’s event focused on Water, Ecosystems and Human Development, with discussions concentrating on how business, NGOs and government agencies are collaborating to address water-related challenges.

Pasteurized Equivalent Water Treatment At High Desert Milk, Idaho, US

Side-Stream SDOX® Systems Enhance Biological Function And Treatment Capacity

Wastewater from the meat processing facility is treated using a sequence batch reactor and an aerobic lagoon that discharges to surface waters following treatment. The facility replaced surface aeration equipment with two, 350-HP the “no-splash,” side-stream SDOX systems retrofitted to the treatment basin. Read the full case study to learn the results.

Advances In Flowmeter Technology

This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.

Boiler Feed Water Pump Local Instrumentation — Necessity Or Nuisance?

Anyone remember the old cars of the 1950s and 1960s? They all pretty much came equipped with an ammeter, an oil pressure gauge, a water temperature gauge, as well as a speedometer and a fuel level gauge. 

How Energy Choices Influence Water Quality

Using earth-friendly energy and conserving water supports the fight against climate change and preserves our freshwater reserves.

Radioactive Waste: Can Membranes Reduce The Fear Factor?

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.

Stormwater: A Valuable Resource For Power Plants?

Stormwater is often thought of as a burden. Too much of it can overwhelm wastewater treatment facilities, flood communities, and lead to the pollution of lakes and rivers. There is debate on who’s in charge of it and how it should be managed. Several communities have invested millions, and some even billions, trying to control stormwater. Even chicken farmers have issues with stormwater.

Benefits Of Clean Power Plan Are Measureable – Drop For Drop

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

Droughts Don't Just Dry Up Water — They Drain Livelihoods And Weaken Local Economies Droughts hit utilities and agriculture hardest. Shrinking water supplies wilt crops and strain water providers. But the impact extends far beyond them.
