  • Particle separation from road runoff by a decentralised lamella system – laboratory tests and experiences in the field

    A new decentralised settling system based on the principle of lamella separation was developed for the treatment of road runoff. Two different laboratory test methods, the DIBt (Deutsches Institut für Bautechnik) procedure and our own approach, were applied in order to evaluate the efficiency of the system based on the separation of fine mineral particles and a mixture of mineral and organic ...

  • Case study - Mazzei airjection aeration system installed in Alabama Field Erected WWTP

    Activated Sludge Treatment in a Municipal Sewage Treatment Plant. Huntsville, AL The Problem: A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP. This plant was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. ...

  • Hart`s E&P: Optimizing production, economics in mature fields

    To generate cash flow in low-price markets, operators have historically turned to the resource they can count on most—fields that have proved they can produce. But optimizing production from mature fields presents its own set of challenges that have the potential to offset the benefits of improved production with higher capital expense. Increasing production while lowering lifting costs and ...

  • Ceramic pot filters lifetime study in coastal Guatemala

    Ceramic pot filters (CPFs) are an effective means of household water treatment, but the characterization of CPF lifetimes is ongoing. This paper describes a lifetime field study in Guatemala which was made possible by a collaboration between researchers, CPF-using households, and local non-governmental organizations (NGOs). Disinfection data were collected periodically for two years using ...

  • Groundwater discharge downstream of an arid inland river in Northwestern China

    Nalenggele River is an inland river located in the arid, fragile ecological environment area in Northwestern China. Groundwater discharge to the river can significantly impact the ecologic environment in the Nalenggele River basin, but few hydrogeological studies have been conducted in the inland arid basin. In this paper, two sections were chosen to analyze the groundwater discharge in the ...

  • Successful Dunbar Field Life Extension

    The advent of high-power multiphase pumps is changing the world of oil production. In particular, they allow continued production from fields that are nearing the end of their useful lives. These revolutionary pumps have been in operation since autumn 1999 on the Dunbar platform, in the UK sector of the North Sea. Multiphase pumping (MPP) is essentially a means of adding energy to the ...

  • Estuary salinity prediction using a coupled GA-SVM model: a case study of the Min River Estuary, China

    Estuary salinity predictions can help to improve water safety in coastal areas. Coupled genetic algorithm-support vector machine (GA-SVM) models, which adopt a GA to optimize the SVM parameters, have been successfully applied in some research fields. In light of previous research findings, an application of a GA-SVM model for tidal estuary salinity prediction is proposed in this paper. The ...

  • Reducing costs through precise remote tracking

    Historically, inline inspection (ILI) tools used to identify defects on oil and gas pipelines have been tracked by field teams. However, recent technology advancements now allow pipeline owners to track pigs remotely, which is a much safer and cheaper alternative to traditional tracking. As pipeline integrity technology advances, asset owners are now using a wide variety of tools to detect ...
