The continuous TOC analysis of industrial waste water is known to be problematic especially, when the TOC analyser is used as a spill monitor for heavily polluted waste water containing a high-load of particles. Thus, most operators require analysers that enable accurate TOC (total organic carbon) measurements. But do they really get those? Common analysers suffer from clogging and blockages due to their measuring techniques using tubes and valves. They require pre-treatment and/ or even filtration of the sample. However, any pre-treatment or filtration will affect the analysers' measuring results. Removing particles means removing carbons and, hence, an inaccurate measurement. In stead of total organic carbon the analyser determines only some organic carbon.
Waste water, especially industrial waste water, is the most challenging water for instrumentation. Mostly, this water is characterized by highly fluctuating loads, very high salt concentrations as well as a high particle density. Hence, the accurancy and speed of measurements depends on the measurement system itself and the oxidation technique used. Obviously, application-specific analyzers provide huge advantages against standard analyzers that are used for all applications.
In September 2012, AdEdge Water Technologies, LLC participated and was awarded a Contract managed by BG Consultants for the equipment pre-selection of a nitrate removal treatment system for the City of Green, Kansas. The scope of the contract included the design, manufacture, and startup of the treatment system. The City of Green is a small community of approximately 125 residents located in northeast Kansas. Water testing revealed a sustained nitrate level of 12 mg/L as N. The United States EPA has set the...
“Mechanically Flawless.” That was the phrase used by the Assistant Facility Manager at a Solid Waste Management Facility in western Minnesota.This particular Solid Waste Management Facility/Waste to Energy Plant has been successfully using Meyer Double Flapgate Valves for over a year. They are handling the abrasive and sometimes chunky ash product left over from burning 220 Tons of garbage per day.Prior to purchasing the valves from Meyer, the local contractor awarded the project contacted Meyer along...
Patoka Lake Regional Water & Sewer District (PLRWSD) serves 11 counties in southern Indiana with a population of around 130,000. The distribution of water travels through approximately 850 miles of pipe ranging in size from sizes 3 to 30 inches and includes numerous elevated towers or tanks in each District Metered Area (DMA). The treatment facilities are fed by an intake structure located at Patoka Lake a little over 1 mile from the water treatment plants. Sean Kluesner is Operations Manager and Jerry...
MPS Betriebsführungs GmbH, based in Berlin, has been using a UNTHA XR3000R waste shredder since early October. The waste treatment plant, which is jointly operated by the ALBA Group and Berliner Stadtreinigung (Berlin’s municipal waste management company), specialises in the production of alternative fuels, and forms part of one of the most modern plants for mechanical-physical stabilisation (MPS) in Europe. The operators were particularly impressed by the way in which the robust UNTHA shredder could...
Industrial Wastewater Treatment
Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time.
In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage Tanks accumulate waste often segregated as acid, alkaline, cyanide and hexavalent chrome-bearing which is transferred to a single...
