Schreiber Foods Cuts Chemical Costs With BlueInGreen's CDOX Solution

At Schreiber Foods' wastewater treatment plant in Utah, mineral acids had been used for pH control in the past but were discontinued due to safety and handling issues. Facility owners desired a safer, more cost-effective solution that would provide automatic control over process pH levels. 

PepsiCo's Vision: Improving Water Wherever It Operates As Senior Director of Global Climate and Water Solutions for PepsiCo, Grant oversees a program that actually improves water conditions, rather than simply mitigating PepsiCo's own impact or embracing sustainability merely for efficiency/business benefits. In this Q&A, Grant details PepsiCo's philosophy on water stewardship, the elements of their ambitious water strategy, and the outcomes they hope to achieve.

Determination Of Pesticide Residues In Tea

In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

A Roundup Of Energy, Water, And Climate Bills In The 84th Texas Legislative Session

We’ve almost made it to the midway point of the 84^th Session of the Texas Legislature. As many already know, the Texas Legislature only meets from January to May every other year, so a lot has to get done in these few months.

Ultrapure Water Treatment: A Market With Energy

A look at the market dynamics and drivers for ultrapure water treatment reveals multiple industries with growing demand, including one that stands above the rest.

KETOS Provides Real-Time Lab Accurate Results For Effluent Water

A leading provider of water and wastewater treatment solution for industrial, municipal, and recreational customers faced a number of issues with the safe treatment and disposal of coal ash and residual ash in ponds. Frequent testing at multiple locations was needed to ensure water safety and compliance. 

EPA Providing Guidance For Drinking Water After Radiological Emergency

What would happen if there was an emergency in the U.S. that caused radioactive material to contaminate drinking water supplies? What steps could your utilities and government take?

TASKMASTER® Helps Make Sludge Into Forest Feed

The Birmingham Wastewater Treatment plant in Kansas City, Missouri is an activated sludge treatment facility that processes 12.4 million gallons of wastewater a day. The facility processes and receives 21,000 dry tons of sludge each year, which is pumped to sludge holding basins. For the last few years, the facility, in partnership with the city, has participated in an innovative recycling project and sludge has played a major role. Its use as fertilizer on land adjacent to the treatment plant has begun to convert the area into forest. It appears to be an environmentally sound, cost effective solution to sludge disposal.

True Corporate Value: How Water Can Affect Shareholder Value

In keeping with the post-Stockholm World Water Week takeaway themes, none was more prevalent than the vital role that the private sector — namely, businesses large and small — must play in the collective pursuit of the Sustainable Development Goals.

Update To Chemical Dashboard Adds Wealth Of Chemical And Biological Data And Improves User Interface

To ensure informed chemical safety decisions can be made about thousands of chemicals, scientists and decision makers need a constantly evolving set of tools for quickly and efficiently evaluating chemicals of interest. EPA scientists have recently released an update to the online Computational Toxicology (CompTox) Chemicals Dashboard to help advance these efforts. The website has been updated with new data and functionality every six months for the past three years.

EPA Researchers Develop A Chemical Category-Based Approach To Prioritize PFAS For Data Collection

The Toxic Substances Control Act (TSCA) requires reporting, record-keeping, testing requirements and restrictions for chemicals of concern, including PFAS. To help meet these requirements, U.S. EPA researchers have developed a chemical category-based approach to help prioritize PFAS for further data collection efforts.

Biofouling Control In Cooling Towers With A Halogen Stabilizer

Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).
