  • Case Study: Major Southern California Studios

    Most studios require - and Ellis is pleased to provide - emergency response services, from mold testing, to indoor air, to asbestos removal. Most recently, Ellis managed a $40,000 cleanup of the air supply system of a huge filming stage, following a fire and resultant smoke damage. Other services provided since 1995 include numerous asbestos and lead surveys, abatement projects, soils testing, ...

  • Using UV Fluorescence technology to monitor for organic pollutants in Flood Water

    For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments.  Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters.  There is however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of ...

  • Protoc TOC succes at Manchester Airport

    The case study outlines the installation of Protoc TOC analysers at Manchester International Airport used for continuous surface water quality monitoring and control. The Protoc TOC instrument manufactured in the UK by Pollution & Process Monitoring Ltd was rigorously tested and was selected for a number of installations at critical drainage locations which have proved the reliability of the ...

  • Quality Data Management: An Essential Component Of US Water Infrastructure

    The standards for environmental testing are more rigorous and far reaching than ever. At the same time, the U.S. water infrastructure has reached the age where replacement is critical. Laboratories and testing facilities trying to address both issues should consider implementing a Laboratory Information Management System (LIMS). A LIMS, which replaces paper-based systems, can increase sample ...

  • Qdos metering pumps usurp diaphragm models

    The revolutionary new Qdos 30 metering pump from Watson-Marlow Fluid Technology Group is proving a resounding success in Barrie, Canada. Located in southern Ontario on the western shore of Lake Simcoe, Barrie is a modestly sized city (135,000 residents) but one with a track record for quality when it comes to its potable water supply. Here, the Water Operations Branch of the Corporation of the ...

  • Error analysis for river water quality prediction using back propagation modelling

    The purpose of this research is to describe the errors of Back Propagation (BP) technique that could be applied in river water quality prediction. ANN was trained by using the upriver data to forecast the downriver quality in two approaches of long-distance forecasting and short-distance forecasting respectively. It showed that the predicted results from short-distance approach were more accurate ...

  • Latex Paint Manufacturer-1

    The paint manufacturing facility was using 1 MGD of fresh water in the manufacturing process with a majority of the water being used for tank and pipe cleaning. As a cost cutting measure, the facility wanted to reduce the water consumption and reuse part, if not all of the wastewater. They tried several different combinations of coagulants and flocculants with limited success. Integrated ...

  • A grey-encoded hybrid accelerating genetic algorithm for parameter optimisation of environmental models

    A new method, grey-encoded hybrid accelerating genetic algorithm, is presented for the parameter optimisation of environmental models. With the shrinking of searching range, the method gradually directs to optimal result with the excellent individuals obtained by grey genetic algorithm embedding Nelder-Mead simplex searching operator. The convergence theorem is given for guaranteeing the global ...

  • Enhanced UV Disinfection by Ozone/Peroxide a Study in Tampa, Florida

    The focus of this presentation is the use of oxidant(s) to enhance ultraviolet (UV) disinfection based on an ongoing project at Tampa’s Howard F. Curren Advanced Wastewater Treatment Plant (HFCAWTP). This approach is unique because it would be the first of its kind in Florida. Systemic bench-scale testing and on-site water quality measurements are used to evaluate the oxidant-enhanced UV ...

  • DelAgua Case Study - Harikar NGO and CARE in Northern Iraq

    Harikar NGO are working with CARE to provide water quality testing in camps for IDPs (Internationally Displaced People), in Northern Iraq. CARE have carried out a 2-day training course with Harikar field staff on the ...

  • Heavy metal levels in tap water in Batina Region, Oman

    Most household in Batina depend on private wells for their fresh water supplies. The quality of such water is not regulated or tested by authorities and, therefore, consumers' health might be at risk if water is contaminated. We assessed the contribution of some heavy metals to water pollution. Water samples from 364 houses were collected and analysed for levels of lead, chromium, nickel and ...

  • Development of Water Quality Test Kit Based on Substrate Utilization and Toxicity Resistance in River Microbial Communities

    Methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. The proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of Biolog’s microplate system. As the microorganism ...

  • Microbiological water quality and sampling policy of public swimming pools

    Water samples collected from 100 public swimming pools in the West Bank of the Palestine by health inspectors. The samples were tested for microbiological quality for the years 2003, 2004 and 2005. The overall of unaccepted tested swimming pool water samples were as follows: 35.8% for total Coliforms (TC), 24.4% for faecal Coliforms (FC), 36% for Heterotrophic Plate Count (HPC), 39.3% Enterococci ...

  • Urban wastewater reuse: a pilot plant experience

    The results of a preliminary verification of domestic wastewater reusability in L'Aquila (Italy) are reported. A Tertiary Treatment Pilot Plant (TTPP), rotary filtration and Ultraviolet (UV) Radiation disinfection, was added to an Urban WasteWater Treatment Plant (UWWTP) to test the compliance with water quality indicated for reuse by the enforced Italian regulation. The TTPP was managed varying ...

  • Cave Researchers Descend Into the Depths with the TROLL® 9500 Water Quality Instrument

    Overview Research of cave pool stratification may help scientists understand the geochemical origin and evolution of cave pool waters (Levy 2008). Dr. David Levy conducted a study to test the hypothesis that certain cave pools may be predisposed to a condition of permanent chemical stratification (meromixis), depending on the specific effects of pool morphometry and localized environmental ...
