World Water Week: Water Management Key Priority For International Oil And Gas Sector

The global oil and gas industry association, IPIECA coordinated a session during World Water Week in Stockholm on water management within the sector from now to 2030.  

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).

AquaDisk® Filters Reduce TSS And NTU For Power Plant Process Water

Shepard Energy Centre (owned by Enmax and Capital Power Corporation) is located in Calgary, Alberta, Canada. It began operating in March 2015 and is capable of generating over 800 megawatts of electricity to Alberta residents using natural gas. The facility utilizes (2) combustion turbines featuring a combinedcycle technology to generate electricity, and in addition, processes waste heat through a steam turbine to produce even more electricity. This electricity generation process makes Shepard approximately 30% more efficient than traditional coal-fired plants, and reduces overall fuel costs. Not only is Shepard’s plant more efficient, but better for the environment by emitting less than half of the CO2 emmissions per megawatt hour compared to a coal generated facility. Sulphur dioxide and nitrogen dioxide emissions are also reduced.

New Hampshire Puts $350 Million To Work From A Successful Lawsuit Over MTBE Contamination

From cleaner water to infrastructure upgrades, good stories are easy to find after the state of New Hampshire set out to hold polluters accountable for contaminating groundwater with methyl tertiary-butyl ether (MTBE), a gasoline additive now banned or limited in several states. Through private well testing, watershed protection and new water facilities, the people of the Granite State are turning the tide on water contamination and restoring the safety and reliability of their drinking water supplies thanks to bold action to make sure polluters pay for damage.

5 Approaches to Treating Wastewater in Beverage (Dairy) Production

Salmon Hatchery Upgrades Its UV Disinfection System

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.

Conducting Accurate Conductivity Measurement In Industrial Applications

While some water quality parameters may get more attention in industrial settings, few are more critical than conductivity. Understanding conductivity monitoring for industrial applications — where it is needed, how it works, and how to leverage the appropriate instruments and standards in order to pinpoint it — will unlock huge gains in efficiency, effectiveness, and regulatory compliance.

Packaged Wastewater Treatment: A Recipe For Success

Food and beverage wastewater treatment demands often fluctuate more drastically than municipal wastewater applications in terms of biochemical oxygen demand (BOD) relating to the foods being processed or to cyclical activity. Modular, self-contained systems offer practical, cost-effective solutions to help food processors keep pace with such variability — as a total or supplemental solution. Here’s how.

Sanitary District Generates EPA Award By Turning Trash To Treasure

The Greater Lawrence Sanitary District (GLSD) in North Andover, MA, was one of 28 organizations nationwide to be honored for an innovative water or wastewater project in the most recent PISCES Recognition Program sponsored by the Clean Water State Revolving Fund (CWSRF). PISCES stands for Performance and Innovation in the SRF Creating Environmental Success.

FGD Purge Treatment In Coal-Fired Power Generation

Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.

These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.

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. 

Compliance Tips For EPA's New Power Plant Regulations

Now that the final rule has been published in the Federal Register, the stage is set for official implementation of the U.S. EPA’s Steam Electric Power Generating Effluent Guidelines on Jan. 4, 2016.

Straight Talk On Radiation

From time-to-time I write on topics that are related to water and wastewater as a "backgrounder" so that those involved in the field can gain a wider perspective and have available to them a cogent explanation minus jargon on various topics. By Dr. J.H. Wakefield

Hydro Schemes Have An Impact In Scotland

At the end of 2011, the total hydroelectric installed capacity in the United Kingdom accounted for approximately 1.67 Gigawatts (GW) of installed electrical generating capacity, being 1.9% of the current total UK generating capacity, and 14% of the UK's renewable energy generating capacity.

Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance

The Cincinnati Zoo uses an ultrafiltration system (UF) to treat stormwater. The reclaimed water is collected from 14 acres of the park, including parking lots, animal exhibit yards, rooftop drains, and walking path storm drains

TOC Reduction For Solar Photovoltaic Plant

Atlantium Technologies installed UV systems in an Indian solar photovoltaic manufacturing plant to remove impurities from ultrapure water, effectively reducing TOC levels and providing high microbial reduction. Their HOD UV technology has been proven effective in water treatment.
