Hydraulic fracturing is a hot-button issue, but no matter where you land you should agree that more efficient produced water filters will go a long way in improving the practice.

It’s been two months since EPA released its much anticipated draft report on hydraulic fracturing, and organizations like ours are busy preparing their official comments, which are due at the end of August. But based on what we have learned so far and what has been written in the media, it’s important to spend some time on what the report said — and didn’t say — and what it all means.

The Western Governors' Drought Forum webinar “Once Marginal, Now Crucial: The Growing Demand for Re-used, Produced, and Brackish Water” explores the technological and regulatory obstacles to utilizing re-used, produced, and brackish water.

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

Bio-UV, a manufacturer of ballast water management systems (BWMS) that utilize UV disinfection, was looking for a reliable and accurate indicative analysis to validate the installation of their BWMS system during commissioning. Read the full case study to learn more.

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. 

Wastewater utilities have a new opportunity to turn their sludge (biosolids) into something special.

A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

As focus on resource recovery intensifies, food and beverage operations are under a particularly large microscope. An anaerobic digester designed for the food and beverage industry can create value out of the space’s unique wastewater.

For distilleries, high levels of biochemical oxygen demand (BOD), nitrogen, total dissolved solids (TDS), and total suspended solids (TSS) put extra pressure on optimal biological treatment requirements. Here are some techniques that can help distillers put a little extra money in the bank while meeting the challenges of environmental discharge requirements.

Reverse osmosis (RO) pre-treatment is used in industrial water filtration to protect the RO membranes, high pressure pumps and other hardware. The performance of pre-filters matters and can impact your operation, in terms of efficiency and water quality.

Being an environmental advocate in Texas may seem like an uphill battle, and I make no bones about the fact it most certainly is.

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

Calcium hypochlorite is a low-cost, solid biocide option for treating cooling towers. This white paper reviews points of consideration when making a selection for a cooling tower water treatment program and highlights advantages to utilizing calcium hypochlorite as a biocide. 

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.

The Archer Daniels Midland Company (ADM) requires full-scale nonchemical disinfection and dechlorination treatment of RO feedwater to the boiler which supports their cottonseed processing facility in Lubbock, Texas.

How new advanced-filtration materials are making headway in treating problematic industrial water streams for reuse or disposal. 

Sometimes simpler is smarter. Mechanical metering pumps can deliver reliable, cost-effective performance in applications that don’t require advanced controls or continuous-duty operation.Sometimes simpler is smarter.

The North American mobile water treatment market was valued at $725 million in 2022. The market is expected to witness a single-digit growth rate during the forecast period, driven by the provisional need for a treatment system in case of plant downtime, facility maintenance, emergencies, or to meet regulatory requirements for effluent discharge. The key challenges in this market include intense competition, the COVID-19 pandemic, and economic volatility.

Ventura County, California, is an agricultural powerhouse. In 2017, its revenues from agriculture were an estimated $2.1 billion. It also faces extraordinary population pressure, with nearly 450 people per square mile — about five times the average population density of the United States. Both agriculture and infrastructure are dependent on, and impacted by, the availability of water — which has itself been impacted by California’s rapidly-diminishing groundwater reserves.

Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.

About 10 years ago, copper replaced aluminum for back end of line (BEOL) interconnects in the semiconductor industry. The downside of using copper for improved semiconductor performance is that it created a copper rich effluent from electroplating that is considered hazardous waste.
