  • Municipal sewer remote monitoring

    Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

  • Use of sewer on-line total solids data in wastewater treatment plant modelling

    We describe a neural network model of a municipal wastewater treatment plant (WWTP) in which on-line total solids (TS) sewer data generated by a novel microwave sensor is used as a model input variable. The predictive performance of the model is compared with and without sewer data and with modelling with a traditional linear multiple linear regression (MLR) model. In addition, the benefits of ...

  • 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 ...

  • An approximate solution for two-dimensional groundwater infiltration in sewer systems

    Estimating groundwater infiltration into sewer systems is important for wastewater treatment operators and municipalities. This paper presents an approximate solution for steady-state groundwater infiltration into sewer systems through line defects. The groundwater table was assumed to be horizontal and the aquifer homogeneous and isotropic. Mobius transformation technique and equivalent ...

  • Alum creek large diameter sewer assessment case study

    The Challenge The City of Columbus, like many municipalities, must make hard decisions on where to spend their limited capital improvement dollars. In tight economic conditions, a municipality’s decision to monitor, rehabilitate, or replace their assets is not cut and dry. Deferred maintenance of non-critical assets in one department may give other departments the monetary resources ...

  • 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 ...

  • Case Study - The performance of the grease degrading bioproduct greasolux in the meat manufacturing factory and municipal WWTP

    Problem A municipal waste water treatment plant in one Baltic town continuously had problems with the fat, oil and grease (FOG) accumulation in the sewer lines, lift stations and waste water treatment plant, since the start up of a local meat processing facility. The highly polluted waste water directly impacted the treatment plant in the following ways: Increased grease ...

  • Improved wet weather wastewater influent modelling at Viikinmäki WWTP by on-line weather radar information

    Municipal wastewater treatment plant (WWTP) influent is typically dependent on diurnal variation of urban production of liquid waste, infiltration of stormwater runoff and groundwater infiltration. During wet weather conditions the infiltration phenomenon typically increases the risk of overflows in the sewer system as well as the risk of having to bypass the WWTP. Combined sewer infrastructure ...

  • Alternatives for Finding Illicit Discharges to Stormwater Systems

    ABSTRACT Provisions of the National Pollutant Discharge Elimination System (NPDES) permits for stormwater discharges require that permits for municipal separate storm sewers systems (MS4s) shall include a requirement to effectively prohibit problematic non-storm water discharges into storm sewers. Emphasis is placed on the elimination of inappropriateconnections to urban storm drains. ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...
