On the small island of St. Thomas, the Mountain Top condominium complex had a big problem: its sequencing batch reactor (SBR) was failing. And a replacement treatment system was needed quickly, because residents relied on the recycled wastewater for use both in toilet flushing and landscape irrigation.
A U.S. light aircraft manufacturing company uses an alkaline cleaner followed by an alkaline de-smutter, rinse, acid de-smutter (possibly using potassium permanganate), rinse, alodine, and a final rinse. The three 1,700 gal rinses are dumped approximately once each week, or more often, based on the pH.
When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
The horizontal, dry-installed pumps at the network pumping station Zell am See were clogging at least 2-4 times a week, also during weekends. Consequently, the pumps had to be lifted and the blockage removed. A high amount of sanitary items and incontinence adult diapers from the nearby hospital were the root cause for the clogging. Read the case study to learn more.
Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.

Tertiary reverse osmosis (RO) wastewater recycling has become a suitable solution to augment water supplies to combat water scarcity across the world. RO desalination in tertiary wastewater processes has proven to provide a cost efficient way to reuse water for both municipalities and industrial organizations.
Your body is a machine. Like most machines, you have to properly maintain your body in order for it to function properly. Along with regular cleaning and checkups, you also have to be cognizant of what food you put into your body or else it won’t work at its maximum potential. An industrial reverse osmosis water treatment system actually works in quite a similar way.
A Q&A with scientist Jeff Urban, who explains forward osmosis and how Berkeley Lab is pushing the frontiers of this emerging technology
As we celebrate Smart Irrigation Month, it's a great time to highlight not only smart technologies, but the smart people and smart decisions behind them. One remarkably smart tool that ties all three of those elements together is the Irrigation Consumer Bill of Rights by Dr. Charles Burt of the Irrigation Training and Research Center (ITRC) at the California Polytechnic State University (Cal Poly) in San Luis Obispo.
Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.
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.
Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.
Collaborative research is a critical element for identifying unforeseen risks associated with using the oil industry’s wastewater outside the oilfield.
