  • Will greywater reuse really affect the sewer flow? Experience of a residential complex in Al Ain, UAE

    Reuse of recycled wastewater is one of the most feasible unconventional urban water sources in the United Arab Emirates (UAE). The extraction and reuse of greywater might affect the water and sewer pipe networks by changing flow characteristics. Therefore, the research question is how much greywater can be reused without affecting the existing water and sewer pipe networks? A residential ...

  • Assessment of inlet efficiency through a 3D simulation: numerical and experimental comparison

    Inlet efficiency is a requirement for characterizing the flow transfers between surface and sewer flow during rain events. The dual drainage approach is based on the joint analysis of both upper and lower drainage levels, and the flow transfer is one of the relevant elements to define properly this joint behaviour. This paper presents the results of an experimental and numerical investigation ...

  • Accepted Inspection Methods of Process Sewers.

    During the process of refining there is discharge of hazardous waste, this coupled with aging pipeline infrastructure creates a potential where waste can leak into the environment posing catastrophic threats to life. Federal agencies such as the EPA are beginning to penalize refineries that do not take necessary measures of disposing their waste. These refineries are subject to ...

  • Sewer Level Monitoring - Photos

    Sewer Level Monitoring - Photos Photos in this article present the complexity and versatility of sewer level monitoring. When examining the photos, pay special attention to the stand-alone autonomous characteristics of each installation. In lack of any cabling from the outside, whether data cables or power cables, the solution is fed from its own battery power supply. Data is tranmitted ...

  • Sewer-Flow Survey Project

    Environmontel Ltd Supply of HydroLog4 time-series database and flow data processing system for sewer-flow survey projects Environmontel Ltd, an established flow-survey company based in Worcester, selected HydroLog4 as their sewer-flow survey information system for use by survey teams on short-term drainage-area surveys and other longer-term monitoring projects. The ...

  • Sewer Level Monitoring System - a case study

    Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend.   Challenges Quantifying sewage flow and level is one of the most ...

  • Efficiency of a turbidity-based, real-time control strategy applied to a retention tank: a simulation study

    This paper compares several real-time control (RTC) strategies for a generic configuration consisting of a storage tank with two overflow facilities. Two of the strategies only make use of flow rate data, while the third also introduces turbidity data in order to exercise dynamic control between two overflow locations. The efficiency of each strategy is compared over a wide range of system ...

  • VOCs Reduces Below Federal MCLs using HRC

    Summary Subsurface investigations at a dry cleaning facility revealed elevated levels of PCE and other regulated daughter products. HRC injection was chosen to accelerate the degradation of the entire range of VOCs. HRC slowly releases hydrogen, enhancing reductive dechlorination in an anaerobic environment. Additionally, HRC Primer, a less viscous version of HRC, was also used to reduce ...

  • Integration of transfer function model and back propagation neural network for forecasting storm sewer flow in Taipei metropolis

    Typhoons and storms have often brought heavy rainfalls and induced floods that have frequently caused severe damage and loss of life in Taiwan. Our ability to predict sewer discharge and forecast floods in advance during storm seasons plays an important role in flood warning and flood hazard mitigation. In this paper, we develop an integrated model (TFMBPN) for forecasting sewer discharge that ...
