  • Real-Time Membrane Fouling Monitoring

    The Port Hueneme Water Agency (PHWA) has been operating a municipal drinking water treatment plant designed to be a Brackish Water Reclamation Demonstration Facility. The facility consists of 3 separate side-by-side full scale systems or trains, each representing a major membrane separation process: nanofiltration (NF), reverse osmosis (RO) and electro dialysis reversal (EDR). Both the NF and RO ...

  • Real-time process dynamics monitoring in Anammox reactors

    Process dynamics in Anammox systems were evaluated through continuous monitoring of pH, oxidation reduction potential (ORP) and conductivity in two separate newly started-up sequencing batch reactors, one seeded with an enriched Anammox sludge and the other seeded with mixed activated sludge. The pH and ORP profiles exhibited characteristic patterns depending on the process dynamics during early ...

  • Real Time Control of the Sewage System in St Malo

    Saint-Malo is an extremely attractive and popular seaside resort on the north coast of Brittany in France. Covering 1,400 hectares, the local population of 50,000 increases to 120,000 in the tourist season. One of the distinguishing features of this part of the Channel coast is a very high tidal range – 14 meters from low to high, with a potential impact back through the sewer network. Combined ...

  • International Tire Recycling Spotlight: Venezuela

    Tire recycling is a serious global concern. Scrap tires take up far too much space, they can spawn devastating tire fires that burn for weeks or even months when stored together in large numbers, and they they leach chemicals into soil and groundwater. Recycling is an absolute necessity, but not easily done. Most developed countries have produced millions of scrap tires (at the very least), and ...

  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • Real-time forecasting urban drainage models: full or simplified networks?

    Lead time between rainfall prediction results and flood prediction results obtained by hydraulic simulations is one of the crucial factors in the implementation of real-time flood forecasting systems. Therefore, hydraulic simulation times must be as short as possible, with sufficient spatial and temporal flood distribution modelling accuracy. One of the ways to reduce the time required to run ...

  • AquaLab Analyzer provides real-time phosphorus measurement in Everglades

    When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

  • Development of a real-time regional-inundation forecasting model for the inundation warning system

    Accurate forecasts of the inundation depth are necessary for inundation warning and mitigation. In this paper, a real-time regional forecasting model is proposed to yield 1- to 3-h lead time inundation maps. First, the K-means based cluster analysis is developed to group the inundation depths and to indentify the control points. Second, the support vector machine is used as the computational ...

  • Innovative Technology Provides Real Time Flow Data Management in Indianapolis

    This paper presents the program developed by the City of Indianapolis for managing its sewer flow data and describes how it is making real-time information available to several groups that have a stake in the City’s environmental management programs. These groups include United Water, the contract operator for the City’s collection system and its two WWTPs, the Capitol Improvement Program ...

  • Optimizing water quality sampling through application of real time ionic concentration regression models

    The Water Resources Management Division of the Department of Environment and Conservation performs routine water sampling to measure the physical and chemical parameters of select water bodies in Newfoundland and Labrador. Ionic concentration parameter measurement is performed during routine water sampling to complement some of the key indicator parameters measured in real time at these select ...

  • Conducting core-sheath polyurethane-PEDOT nanofibres for conducting polymer actuator

    Conducting core-sheath nanofibres were prepared by the vapour-phase polymerisation of poly(3,4-ethylenedioxy thiophene) (PEDOT) on electrospun polyurethane (PU) nanofibres both with and without incorporating graphene nanoplatelets (GNPs) as the core part. The morphology, mechanical properties, electrical conductivity, and electroactive actuation of the core-sheath nanofibres were investigated. ...

  • Estimating soil conductivity for GPR surveys

    The results of a ground penetrating radar survey depends on many factors. In order to get useful data and good penetration, one of the conditions is that the conductivity of the ground is not too high. The conductivity of the material together with the operating frequency and the dielectric constant allow us to calculate the loss factor that is used to roughly estimate the theoretical ...
