The water used in cooling water systems must be filtered to reduce particulates and help protect downstream process equipment from various sources of contamination at numerous entry points.

Onshore Crude Oil Decontamination Using A Water Security Test Bed

Onshore crude oil production has increased in the United States over the past few years. Oil producers, specifically the North Dakota Pipeline Authority and the Bakken Shale field producers are transporting crude oil by rail and train to both the East and West Coast oil refineries. While rail tends to be one of the safer and more efficient ways of transporting crude oil, there is still a risk of a spill. Oil spills are threats to both ground and surface waters, which can ultimately impact drinking water.

Fuel And Fuel Additives

Some fuel-related contaminants can be found at a majority of the United States Environmental Protection Agency’s (USEPA) National Priority List Sites, where they pose a potential threat to human and environmental health.

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.

Water Management For Fracking Evolves

To date, the bulk of analysis on the U.S. fracking industry has largely centered on well counts and oil and gas production.

Determination Of Hexanal In Foods Utilizing Dynamic Headspace

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

Milk Waste - BOD, FOG, PO4

A milk producer operates an evaporated milk production facility that generates an average of 58,000 gpd of contaminated water with spikes of 1,200 gallons up to 12 times per day. Two 2,000 gallon batch tanks are used for pH adjustment before discharge. Most of the flow goes through the tanks.

Combined-Cycle Water Treatment System

The client was in need of both a raw water and wastewater treatment system for its new 1,100-megawatt (MW) natural gasfired combined cycle power station that was being built to replace an existing 400-MW coal-fired plant that had been decommissioned previously. Veolia Water Technologies was contacted to engineer, procure and supply a 6,000 gallons per minute (GPM) raw water treatment system and a 1,200-GPM wastewater treatment system.

Power Resiliency Tips For Water And Wastewater Utilities

Are you prepared to keep services up and running if the grid goes down?

Can Co-Locating Utilities Solve The Water-Energy Nexus?

Resources being a scarce commodity, it’s incumbent upon us to optimize the use of water and energy as best we can. While conservation is the prime course of action for the public, the best solution for utilities may be to work smarter — by having the water-energy nexus work for us instead of against us.

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.

Why It's Time To View Plastic Pipe In A Whole New Light

Because recent advances in plastic materials and processing have led to a new generation of plastic piping systems to handle challenging water and chemical environments, it is important to understand why some older piping choices might no longer be the best bet. Here are some key reasons to consider new plastic-piping choices for municipal and industrial water/wastewater applications in a whole new light.

Liqui-Flux Case Study: Large-Scale Treatment Of River Water For Industrial Use

Ultrafiltration (UF) is commonly used as a pre-treatment to Reverse Osmosis (RO) to ensure reliable, consistent and efficient operation. As Shandong Hongxin Chemicals Co., Ltd in China recently discovered, this consistency and reliability, along with quick setup and installation times, helped them realize convenience and cost savings.

TEQUATIC PLUS Filtration Skids Help Protect Your Salt Water Disposal Wells

In the world of Salt Water Disposal Wells, protecting the well from intrusion by solids is a key need. Filtering the high solids present in produced and flowback water to <20 micron prior to injection in a high Total Suspended Solids water condition has proven to reduce the time between acid cleanings and flowback cleanings.

Keeping Polar Regions Ecologically Safe

With a growing trend in expedition-type cruising and an increase in commercial shipping traffic navigating the Northern Sea Route and to a lesser extent the Northwest Passage, the need for the regular and accurate monitoring of a passenger vessel’s ballast water treatment system (BWTS) has never been so acute.

Hydroponic Growth And Testing

What is hydroponics? "A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form.

High Efficiency Media Filtration And Ultraviolet (UV) Disinfection Is Becoming A Crucial Component For Today's Cooling Tower Needs

An increasing number of technology industries are turning to cooling towers to remove excess heat from buildings or processes. Server farms or server clusters are typically located between the system switches and routers, the removal of heat from these facilities is critical to their optimal performance.

GeoSpray® Arched Storm Culvert Rehab

During inspections of its road culverts, the city of Rock Springs discovered a corrugated metal culvert that was considered in danger of imminent failure. The 700-foot culvert in question was arched with a maximum height of 48 inches and a maximum width of 72 inches. The invert of the pipe, which was covered with dirt and trash, was mostly corroded away. In fact, approximately 18 inches of the underlying soil had been eroded along the full length of the culvert. In addition to the invert, there were joint separations of more than six inches in many of the joints. The crown had also caved in over a 10-foot section of the structure running directly under the road.

Geospatial Patterns Of Antimicrobial Resistance Genes In The EPA National Rivers and Streams Assessment Survey

Both antimicrobial products and antimicrobial-resistant bacteria find their way into the environment through the release of treated wastewater into rivers and streams, as well as through runoff from animal feeding operations. EPA researchers are engaged in a variety of efforts to understand what happens when antimicrobial-resistant bacteria (sometimes referred to as antibiotic-resistant bacteria) are released into the environment.
