Are you for or against it? It seems everyone has picked a side in the debate over hydraulic fracturing (“fracking”), but most conflict would likely fall away if fracking was performed in a proven safe and sustainable manner, verified by a reliable source.

Speaking on the state of the challenging water/wastewater treatment market — hampered in recent years by slow municipal growth — Heiner Markhoff, a leading voice in the water treatment technology market, sees “light at the end of the tunnel.” Find out why in this exclusive Q&A with Water Online.

Many processes in the oil/gas refining, specialty chemical production, solvents, paint, coatings and photoelectric industries generate hazardous air pollutants (HAPs) and volatile organic chemicals (VOCs), which need to be removed from waste, flue and tail gases before emission into the environment to meet clean air regulations around the world. In addition to removing problematic greenhouse gases, emphasis is placed on eliminating toxins that can be harmful to industrial workers and the environment.

The accurate measurement and disposal of flare gases aboard floating production storage and offloading (FPSO) vessels is essential to manage these potentially hazardous combustible, flammable and toxic gases. Accurate measurement of these waste gases allows them to be processed efficiently and effectively to protect people and equipment aboard the vessel. Measuring of flare gas is also most often a strict regulatory requirement, as it can form the basis for payment of environmental taxes, climate quotas, etc.

Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

While the facility was receiving awards and accolades for their aquaculture production, they were having challenges keeping their former UV system operating consistently and reliably. Spare parts were expensive and they often experienced periods of down-time, negatively affecting operations.

Due to new rules proposed by the FDA, monitoring services and new pumps will likely be shopping-list items for food processors.

A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.

Read about a technology that dairy plants can take advantage of to optimize the treatment of their wastewater and assure consistent compliance to effluent discharge permits.

A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation.

The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

This article is the first of two in a Women’s History Month series that showcases a handful of the National Renewable Energy Laboratory’s (NREL's) outstanding women researchers in water power.

Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

As the global economy starts fully integrating other sources of energy in addition to fossil fuel, solar and wind, green hydrogen is starting to gain momentum.

The Prince William County Service Authority carefully considers its impact to the environment when conducting wastewater treatment.

In the semiconductor industry, ultrapure water usage can be in order of 2 to 4 million gallons a day. The entire ultrapure water treatment process is comprised of two segments: makeup water and a high-purity water loop.

Industries around the world are seeking new ways to make every drop of water count. Agriculture, which uses a high 70% of the world’s fresh water, is no different. By Donna Vincent Roa, PhD, ABC, CSR-P

Aquafine ultraviolet (UV) systems are engineered to focus the power of concentrated UV light utilizing one or several specially designed Aquafine ColorguardTM UV lamps, recognized in the industry for performance and reliability.

As nutrient pollution increases the incidence and severity of harmful algal blooms, it is obvious and important to point mitigation practices toward a prime culprit — the agriculture industry.

The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.
