Produced Water Management: An Overlooked Subject In Academia

Water is one of the world's most critical natural resources, but too many people take it for granted, raising awareness of its importance — and complexities — is too often left out of public discourse. My recent visit to a few engineering colleges as a STEM ambassador made me realize that many engineering programs are offered today than when I went to school.

Utilizing Thermal Mass Flow Meters To Optimize Thermal Oxidizer Performance And Reduce HAP/VOC Emissions

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.

Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization

Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

Treating Food Wastewater Efficiently Using Jet Aeration

Food processing is a water-intensive process, and its wastewater byproduct is typically high in volumetric daily flow and also biochemical and chemical oxygen demand (BOD and COD), organics, and nutrients. Consequently, significant on-site treatment and resources are necessary.

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.

Online Total Nitrogen Analysis Of Reverse Osmosis Reject Water Reduces Permit Compliance Expense By $350,000 Annually At Beverage Bottling Plant

Learn how a beverage plant cut its annual Reverse Osmosis reject water hauling volume by 50%. Real-time Total Nitrogen monitoring reduced compliance costs by $350,000 and eliminated discharge penalty risk.

Wastewater Management In The Food Industry Food production not only uses a lot of water in their products, but they also deal with unique wastewater challenges. These challenges are compounded by the varying nature of contaminants present in food & beverage wastewater. Treatment facilities must be designed to handle fluctuating volumes and compositions of wastewater, while maintaining consistent performance.

Improving Compliance Through Real-Time Phosphorus Control

Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

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.

In Times of Drought: 9 Economic Facts About Water In The United States

This Hamilton Project memo presents nine economic facts that provide relevant background context to the water crisis in the United States.

Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization

Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

Desalination And Power Plants—An Ideal Partnership?

A partnership between power and desalination plants may be the solution to drinking water scarcity. Researchers are working on a new system that can create potable water using a low-temperature desalination process powered by waste heat from a waterless power plant cooling system. 

Power-Gen Efficiency Boosted By Clamp-On Flow Meters

When an energy storage facility in New York, USA was looking for a way to improve the efficiency of their power generating turbines they did not have many options to choose from. Because of the sheer size, the space limitations and performance requirements of the application, the only option was to install a SITRANS FS230 clamp-on ultrasonic flow meter from Siemens. 

Treating Food Wastewater Efficiently Using Jet Aeration

Food processing is a water-intensive process, and its wastewater byproduct is typically high in volumetric daily flow and also biochemical and chemical oxygen demand (BOD and COD), organics, and nutrients. Consequently, significant on-site treatment and resources are necessary.

Cost-Effective Telemetry For Agricultural Applications

Implementing telemetry — the ability to transmit flow meter readings — allows water managers in irrigation districts and small rural systems to work smarter, not harder, by aggregating critical, real-time flow information. Until recently, telemetry was expensive and plagued with problems. However, advanced technology offers an ideal solution.

TSCA Modernization: A Dose Of Common Sense

After 40 years, the 1976 Toxic Substances Control Act (TSCA) has finally been updated, much to the delight of most — but certainly not all.

Recycling Dairy Farm Wastewater For Irrigation Purposes By Using ABF Filters

In order to use pond water for irrigation, a filtration system was required with the ability to handle high loads of suspended solids as well as the suspended organic loads from the pond. Learn how Amiad supplied a solution.

New Drinking Water Regulations Sought For Algal Toxins

Excess nutrients, blue-green algae (cyanobacteria), and cyanotoxins have long been a problem for wastewater treatment plants — many states regulate nutrient levels in discharged water — but now drinking water plants are being eyed for regulation as well.

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.
