The Huber Technology EscaMAX® gives control over what gets in the stream whereas their previous process gave them no way to prevent rag balls from flowing into pumps and mixers and causing slowdowns and clogs.
Efficiency goals met! Life expectancy of expensive variable frequency drives increased! Ragging build-up on selector mixers all but eliminated! Reduction of debris from 25-30 gallons to a few handfuls! Highest possible percentage of inorganics removed from flow! Plant kept in amazingly consistent treatment mode! These are not the dreams of treatment plant supervisors but are actual results produced by EscaMAX® Perforated Screens.
Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products.
After researchers from Virginia Tech pioneered efforts to test for and remediate lead contamination problems in Flint, MI, the school has received a considerable grant for undertaking similar efforts around the country.
The conditions for water purification in the pharmaceutical industry are subject to stringent standards. Satisfying these requirements is essential for companies wishing to prove that their products have been safely produced and are suitable for sale both at home and overseas.
When it comes to the use of electronic equipment in water purification, the de facto standards are set by the International Society of Pharmaceutical Engineers’ (ISPE) Good Automated Manufacturing Practice (GAMP) guidelines.

The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.
Unless you spent the last election cycle hiding under a rock (and no blame if you did), you are no doubt aware of the growing rift between the two major political parties of the United States. As reported in The Atlantic citing polling from the Pew Research Center for the People and the Press, those who identify as Democrats are becoming more liberal and those identifying as Republicans swing ever more conservative.
The legislative body responsible for ensuring that the federal government remains accountable has recently issued a report on the nation’s lead contamination problem. Its recommendations may be what finally save the country’s drinking water.
Weather plays an important role in how Americans think about water. And I don’t mean when it’s raining, we decide to grab a raincoat.
Though it may surprise most Americans, there are plenty of places in this country that do not have access to clean water. And a recent news report put the blame for that on the current Presidential administration.
The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life –from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA™ Denite® technology is treating 450+ MGD in the Bay.

The question of how to get the most out of the data that we collect as an industry was central to the Sensing in Water Conference recently hosted by the Sensors for Water Interest Group (SWIG). The two-day conference highlighted several themes on how to get the best of the data that the Water Industry collects and how to make our measurements “meaningful.” Chief among those themes was greater collaboration among the different stakeholders, including water companies, universities, and the supply chain.
Though the field of water loss management is ever-growing and refining, a validated water audit to disaggregate volumes and values of all loss components remains the essential first step to reduce water loss in a way that is economically sustainable, both for your utility and your ratepayers. With extreme weather events, conservation rate structures, and regional population shifts changing the face of business as usual, it’s time to get with the program.
New water brings new challenges, such as overcoming heightened regulatory standards and consumer wariness. To ensure water quality and quell concerns, utilities moving toward alternative water sources might also consider updating their monitoring technology.

The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve their effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate. Read the full case study to learn more.
Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.
