  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • 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 ...

Measurements of acetylene were made as under laboratory conditions and in ...

  • 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 ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • 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 ...

  • 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 ...

  • 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 ...
