The new T-CUT tubular modules (photo) with membranes made from polyvinylidene difluoride (PVDF) or polyethersulfone (PES) complement this company’s CUT product range with a robust and efficient tubular module. The outstanding stability of the membranes and the possibility to apply…
The Sentinel Float Stick System (photo) serves as a wireless-communication link in the remote monitoring and control of tank levels and temperatures for offsite data processing. Consisting of a magnetostrictive level probe with integrated temperature sensors mated with a Sentinel…
Process monitoring and automation can improve efficiencies in wastewater treatment systems. A number of parameters well worth monitoring, as well as tips for implementation are described There is growing interest in automating wastewater treatment processes across a broad range of…
Excessive growth of filaments and biopolymers in activated sludge should be controlled in CPI wastewater-treatment plants, as both lead to sludge that is hard to handle. The sticky behavior of such sludge can be minimized by the addition of polyaluminum…
Understanding pump internals, especially the various sealing and coupling arrangements, is a critical step in selecting the optimal pump There is a significant risk for operators associated with the pump selection process. Economic issues, such as procurement and operating costs,…
Advancements in efficiency and the ability to handle a wide array of chemicals combine to make the air-operated double-diaphragm (AODD) pump a useful choice for chemical processors The circumstances surrounding the development of the air-operated double-diaphragm (AODD) pumping principle six…
Presented by The Water Environment Federation (Alexandria, Va.; www.wef.org), the Weftec 2016 conference and exhibition will take place Sept. 24–28 at the Morial Convention Center in New Orleans, La. In addition to an exhibit hall featuring nearly 1,000 exhibitors, this…
This methodology facilitates multifactor testing. However, it comes at a price: a loss in power for detecting effects The traditional approach to experimentation — often referred to as the “scientific method” — requires changing only one factor at a time…
The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration, in partnership with the National Institute for Occupational Safety and Health (NIOSH), have initiated a "Hear and Now – Noise Safety Challenge." According…
The new wirelessly monitored Enardo 2000 emergency pressure-relief vents (EPRVs; photo) provide safety control by managing abnormally high storage-tank pressures in the oil-and-gas, chemical, petrochemical and pharmaceutical industries. Under normal operating conditions, an EPRV remains closed. The immediate knowledge of…
