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.
Making wet waste destruction a sustainable reality
Irish environmental company SCFI was supported by the European Union’s Eco-Innovation initiative in a project to build a portable unit to demonstrate its innovative AquaCritox wet waste treatment technology. This White Paper describes the science behind hydrothermal oxidation (HTO) as a waste treatment methodology and its potential across a range of industrial applications, which is now, thanks to this project, a demonstrable reality.AquaCritox and Hydrothermal OxidationAquaCritox is a hydrothermal oxidation...
Forensic Analysis of Horizontal Well Systems - Case Study
Project Location: Eastern New York Client: Public Utility – Major Airport Contamination: Jet Fuel Site Size: 10+ Acres Project Description: Having contracted with a large nationally known Environmental Remediation Company to design and install numerous horizontal well deployed AS and SVE systems to clean up their extremely large plume of JP fuel, a major east coast Client became very concerned that the firm`s systems were not functioning as routinely reported (and hence, remediation was...
City of Green, Kansas Nitrate Reduction - Case study
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...
Meyer’s “Mechanically Flawless” Double Flapgate Valves - Case Study
“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 Plant upgrade requires new control valves
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...
