The Rosemount CT5400 continuous gas analyzer (photo) combines tunable diode laser (TDL) and quantum cascade laser (QCL) technologies within the same analyzer, and uses a patented “laser chirp” to provide near-instant high-resolution spectroscopy to detect and identify a range of…
More than 70% of operating costs of a wastewater treatment plant are related to energy costs, arising when the aeration tanks are provided with air. The combination of this company’s blower, turbo and hybrid technology has previously offered efficient solutions…
This company has extended the range of its model 55 bimetal thermometer (photo), which is now available in a version that can withstand ambient temperatures down to –70°C. Following the release of the PG23LT pressure gage, the company now also…
Requiring no integrated plant air to function, the MCF PowerSaver dust collector (photo) generates energy cost-savings of up to 50% over conventional high-pressure pulse-jet or reverse air-cleaning systems, says the company. The MCF is built to handle heavy dust…
The UniMax series of floor-mount fume hoods (photo) includes a wide selection of models that feature fire-suppression systems. Standard models are available as follows: 6 to 24 ft wide; 4 to 8 ft deep; and 7 to 16 ft high.…
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,…
