Wastewater streams from petroleum refineries present some of the largest ranges of variation in contaminant loadings and contain some of the toughest contaminant profiles to treat. These factors render the wastewater treatment processes difficult to control. The most challenging area…
BASF SE (Ludwigshafen, Germany; www.basf.com) has signed an agreement with the investor group of inge watertechnologies AG (Greifenberg, Germany; www.inge.ag) to acquire the company and its ultrafiltration membrane business. “This transaction is an important step in strengthening BASF’s technology and…
Water systems are common in the chemical process industries (CPI). Mixing, heating, concentrating and evaporating water in these systems will often result in an accumulation of inorganic scale, which can markedly decrease process-system efficiency. Scale inhibitors are chemical substances that,…
The DCP007 Series of industrial photometers (photo) can measure the concentration of light-absorbing substances over the wavelength of 280 to 2,000 nm. The new units use solid-state LED lamps and laser diode technology, and a dual wavelength, four-channel measurement technique…
Pieralisi Launched at IFAT last month, this new series of decanters (photo) has been designed specifically for the dewatering of sludge from industrial wastewater. The designers of the new decanter series have given particular attention to energy savings: thanks to…
Last month, a total of 17,722 visitors and 995 exhibitors attended WEFTEC.09, the Water Environment Federation’s (WEF) 82nd annual technical exhibition and conference held in Orlando, Fla. Particularly in this time of economic concerns, the strong showing reinforces the importance…
BioAir Solutions Using its proprietary EcoBase synthetic media, this firm has developed a line of odor control products (photo) that remove both organic and inorganic odorous compounds from the airstreams of industrial wastewater-treatment plant. Units are available for covering airstreams…
Microorganisms in a biofilm wastewater-treatment process are typically more resilient to process disturbances when compared to other types of biological-treatment processes. In the AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) technology, the biofilm growth is protected within engineered plastic carriers that…
GE Energy Introduced in August, TrueSense (photo) integrates three new and unique functionalities into one platform: direct online monitoring of critical water chemistries; personal instrumentation that dramatically cuts offline testing time; and a powerful data analysis and display capability. A…
The cost for sludge treatment — in terms of manpower, equipment and energy — accounts for about 50% of the overall cost of wastewater. Since most end users require that the sludge be transported to another destination, it is important…
