A Kaeser EBS series screw blower is making wastewater treatment considerably more efficient and effective at the Goldsteig dairy factory in Cham in the Upper Palatinate region in Germany.
This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.
Orenco Systems® Inc. (Orenco) recently completed the sale and commissioning of a wastewater treatment system for the Soyo Municipal Hospital in Angola.
A large percentage of the flow meters purchased for municipal water plants are replacements for older meters in existing facilities or distribution systems. It’s a common practice to replace aging meters with the same technology, often from the same manufacturer.
Two phase flow is notoriously problematic for most flow technologies. Read how ABB is tackling the 2-phase flow problem through an entire meter-design approach, which entails a state of the art electronics platform and innovative sensor technology. By Ron DiGiacomo
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.
Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

The Brushy Creek Municipal Utility District (BCMUD) in Brushy Creek, TX contracted Pall in 2014 to perform a process study of a microfiltration system first commissioned in 2006, and expanded in 2009.
Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.
Though they all must support routing functionality, some devices do it better than others.
Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.
Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.
UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.
Bristol-Myers Squibb (BMS) is a global pharmaceutical and related health care company with the mission to extend and enhance human life. One of the company’s oldest and largest facilities was built in 1943 in East Syracuse, New York, when BMS was one of 12 companies chosen by the federal government to mass produce penicillin.
Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes. By Bob Dabkowski, Hach Company
Questions about if and how hydraulic fracturing activities can contaminate drinking water have been top-of-mind for many since the practice started getting widespread public attention about a decade ago. Recognizing the validity of those concerns, EPA undertook a study to see how the full ‘hydraulic fracturing water cycle’ could potentially impact our drinking water resources.
The Lancaster Area Sewer Authority’s (LASA) recent $26.8 million upgrade to its lone wastewater treatment facility promises to reduce the plant’s environmental footprint and save costs by emphasizing energy efficiency and allowing for biosolids reuse.
Three key events from 2015 could reshape the water/wastewater industry in 2016 and for years to come.
Thermal hydrolysis is an innovative wastewater solids conditioning process that boasts many advantages — financial, environmental, and otherwise. Is your plant a good candidate?
While chlorination has long dominated water disinfection, new approaches and technologies have emerged in the wake of disinfection byproduct (DBP) regulations. Could peracetic acid (PAA) be the option that dethrones the king?
The “flushables” scourge has cost utilities all over the world millions of dollars and countless hours of maintenance. Some groups are attacking the problem at its source.
