  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • IWA Smart Networks Cluster (SNC)

    Future networks need to be resource efficient, in regards to using less energy, enable easy recovery of resources from wastewater and reduce water losses in distribution systems. At the same time, performance and service levels need to meet ever stringent standards whilst investments and ongoing maintenance of infrastructure are cost-effective. Integral to such networks will be technologies that ...

  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • Bioaugmentation In Sewer Network Reduces Sludge Production

    This article describes the effectiveness of bioaugmentation in the sewer network as a strategy to reduce sludge production. Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing ...

  • Development of monitoring and evaluation system for wastewater issues in Palestine

    Wastewater is the main source of groundwater pollution if it is not properly collected and treated. In many parts of the Gaza Strip and the West Bank wastewater is collected through cesspits, while in other areas it is collected through networks and treated in central treatments plants. Collecting aggregate information on the level of indicators with concern to the wastewater issues (collection, ...

  • Study on wastewater treatment systems in hospitals of Iran

    Water resources shortage is one of the most important issues due to the population growth and ever increasing water demands as well as its conservation. Wastewater treatment can serve as a logical way to recycle water to consumption cycle. Due to variety of water uses, it seems that there are certain treatment techniques for different types of wastewater, such as municipal and hospital ...

  • On the usage of artificial neural networks in chlorine control applications for water distribution networks with high quality water

    Artificial neural network (ANN) methodology has found some recent applications as efficient control tools for satisfying free residual chlorine (FRC) levels at critical locations of water distribution systems. This particular research was started to critically investigate the potential and applicability of the ANN approach as a tool for controlling FRC levels for complex water distribution ...

  • Control of Wastewater Treatment Plants

    Instrumentation, control and automation (ICA) of wastewater treatment systems and sewer networks have attracted much attention since the early 1970s. The developments during the last four decades in on-line instrumentation, computer technology, process understanding and subsequent model development, and control methods have been powerful driving forces for advanced control making ICA ever more ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • Advanced nitrogen removal using pilot-scale SBR with intelligent control system built on three layer network

    Since eutrophication has become increasingly severe in China, nitrogen and phosphorous have been the concern of wastewater treatment, especially nitrogen removal. The stabilization of the intelligent control system and nitrogen removal efficiency were investigated in a pilot-scale aerobic-anoxic sequencing batch reactor (SBR) with a treatment capacity of 60 m3/d. Characteristic points on the ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • Impact of water source management practices in residential areas on sewer networks – a review

    Prolonged drought which has occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices, which are called source management practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, ...

  • Bioaugmentation in Sewer network reduces sludge production case study

    Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing municipal plants. The costs of sludge management account for 55% of the total WWTP operating cost and 35° o of the capital ...

  • Wastewater System Consent Decree Program Management case study

    City and County of Honolulu, HI Honolulu, Hawaii, USA The City and County of Honolulu (CCH) manages over 100 million gallons of wastewater per day through a network of 2,100 miles of pipelines, 70 pumping stations and nine wastewater treatment plants. In 2010, CCH, the US EPA, the state of Hawaii and other non-government organizations entered a Consent Decree (CD) ...


  • Assessing the efficiency of different CSO positions based on network graph characteristics

    The technical design of urban drainage systems comprises two major aspects: first, the spatial layout of the sewer system and second, the pipe-sizing process. Usually, engineers determine the spatial layout of the sewer network manually, taking into account physical features and future planning scenarios. Before the pipe-sizing process starts, it is important to determine locations of possible ...
