Traditional dissolved-air flotation systems produce the flotation motive water through air saturation of a partial flow in the plant outflow. The saturation usually takes place using multi-stage pumps, which only run smoothly if they are fed with pH-neutral wastewater that…
The new Allen-Bradley CompactLogix 5380 controller (photo) provides up to 20% more application capacity than previous CompactLogix versions. This controller is particularly helpful for high-speed packaging applications where fast response times are critical, says the manufacturer. Features such as scheduled…
This company has added four additional sizes to the Arctic Series of condensing boilers (photo). The new models range from 1.5 to 3 million Btu with certified efficiencies of 95%. The stainless-steel boilers feature a non-welded heat exchanger. Arctic boilers…
With a design pressure of up to 21 bars (305 psi), the FrontLine gasketed plate heat exchanger (photo) allows a flexible design with plates tailor-made for demanding hygienic applications. The plate pattern, the channel depth and the overall dimensions are…
With a wide range of flowtube sizes and an array of available transmitter configurations, the MagPLUS family of magnetic flowmeters (photo) offers precise, bi-directional metering of many types of fluids, from beverages and processed foods to potable water, industrial water…
This cable- and pipe-transit provider has introduced a high density (HD) cable-entry device for use in terminal boxes and enclosures (photo). The HD cable entry system meets challenges with high cable density in applications with that demand the utmost in…
To ground and monitor multiple pieces of equipment, such as loading and mixing stations for tanks or railway cars, a large number of conventional static ground systems would normally be required to provide adequate protection against incendive electrostatic sparks. In…
A hybrid process that combines micro-flotation and flat-sheet ceramic-membrane filtration to remove oil and suspended solids from difficult-to-treat industrial wastewater has been commercialized by akvola Technologies (Berlin, Germany; www.akvola.com). The system can treat water with high oil loads (up to…
A scaled-up version of an electrochemical cell with boron-doped diamond electrodes has been introduced, and the system treats wastewaters containing difficult-to-oxidize dissolved pollutants. Known as Diamox, the electrochemical oxidation cell was developed by Element Six (www.e6.com), a designer and manufacturer…
An all-weather solar cell that generates electricity by both sunlight and rain has been developed by researchers led by professor Qunwei Tang from the Institute of Material Science and Engineering at Ocean University of China (Qingdao; http://eweb.ouc.edu.cn) and professor Peizhi…
