  • Municipal Wastewater

    Municipal wastewater namely sewage is generated by residential, institutional, commercial and industrial establishments. It includes household waste liquid from toilets,baths,showers,kitchens, and sinks drained into sewers. In many areas, sewage also includes liquid waste from industry and commerce. The separation and draining of household waste into greywater and blackwater is becoming more ...

  • Sustainable Treatment and Reuse of Municipal Wastewater

    The uncontrolled disposal to the environment of municipal, industrial and agricultural liquid, solid and gaseous wastes constitutes one of the most serious threats to the sustainability of the human race by contaminating water sources, land and air, and by its potential contribution to global warming. With increasing population and economic growth, treatment and safe disposal of wastewater ...

  • A health risk assessment of reclaimed municipal wastewater for industrial and miscellaneous use

    The study evaluated the safety of reclaimed water using health risk assessment and biotoxicity tests. The reclaimed water was produced from reverse osmosis and used in industrial and miscellaneous purposes. The health risk assessment was conducted based on the concentrations of detectable pollutants in reclaimed water in a hypothetical scenario. The estimated carcinogenic and non-carcinogenic ...

  • UV set to dominate the municipal industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes. Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped.  Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...

  • Test organisms behaviour on municipal and industrial wastewater quality assessment

    Industrial wastewaters quality became a target for the environmental toxicity assessment nowadays. When there are issues with complex effluents for which many chemicals cannot be quantified and/or interactive effects are likely to be significant, the use of bioassays with different test species becomes a more reliable way in the assessment of toxicity. Ecotoxicity evaluation of the several ...

  • Performance of A-stage process treating combined municipal-industrial wastewater

    A biosorption column and a settling tank were operated for 6 months with combined municipal and industrial wastewaters (1 m3/hr) to study the effect of dissolved oxygen (DO) levels and Fe3+ dosage on removal efficiency of dissolved and suspended organics prior to biological treatment. High DO (>0.4 mg/L) were found to be detrimental for soluble chemical oxygen demand (COD) removals ...

  • Treatment of municipal wastewater by membrane bioreactor: a pilot study

    The operational performance of a submerged hollow fibre Membrane Bio-Reactor (MBR) for treatment of municipal wastewater on pilot scale was investigated. The experimental results indicated that the removal efficiency for SS, COD, NH4-N, turbidity, bacterium, iron (Fe2+) and Manganese (Mn2+) was 100%, 94.5%, 98.3%, 99.7%, lg6, 99%, 92.3%, respectively. The water quality of the effluent was quite ...

  • Integrated Anaerobic and Aerobic Processes for Treatment of Municipal Wastewater

    ABSTRACTIn this study, integrated anaerobic and aerobic treatment processes for municipal wastewater treatment were investigated for its feasibility to replace the existing conventional activated sludge process. Three types of anaerobic systems − anaerobic sludge blanket, anaerobic sequencing batch reactor and anaerobic filter, as the pretreatment step were studies. High solids and organics ...

  • Municipal Wastewater Treatment - Prichard, Alabama - Case Study

    TenCate  develops and produces materials that function to increase performance, reduce costs, and deliver measurable results by working with our customers to provide advanced solutions. THE CHALLENGE Prichard AL is a town of about 30.000 people north of Mobile. AL Paul David, the Sewer Board Superintendent, oversees the contract management of two (21 ...

  • 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 ...

  • Toxicity reduction in industrial and municipal effluents – the state of the art

    Developments in treatment technology have traditionally focused on removal of specific contaminants: BOD, solids, ammonia, TOC and lately, specific organics such as phenol. A limit on effluent toxicity, however, does not fit so neatly into a procedural package, since it truly integrates the presence and impacts of contaminants in a sample. Toxicity reduction evaluation procedures, therefore, are ...

  • Removal of Particulate and Organic Matter from Municipal and Industrial Wastewaters Using Fine Mesh Rotating Belt Sieves

    The Salsnes Technology has been developed to work as a stand alone unit or an addition to primary wastewater treatment facilities. The process incorporates an continuous mesh screen that uses air as backwash therefore producing a high dry solids content waste. The technology has been widely accepted in Europe and work is being done in North and South America including installations and pilot ...

  • Reclaimed Municipal or Industrial Wastewater for Power Plant Cooling & Boiler Feed Make-Up Water

    For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. State and Federal agencies have put in place guidelines and regulations restricting its use, especially for industrial use. ...

  • Analysis of the impact of the industrial fat, oil and grease (FOG) on a municipal wastewater treatment plant by means Respirometry and microscopic Bioindication

    The main impact that the industrial fat, oil and grease (FOG) could make in a municipal wastewater treatment plant is mainly coming from its slowly biodegradable COD (sbCOD) The wastewater entering in a municipal WWTP tends to include a percentage of slowly biodegradable COD in the range of 35 to 65% of the total COD; but when this percentage surpasses the habitual range, normally it is due to ...

  • Creation of a sustainable water resource through reclamation of municipal and industrial wastewater in the Gippsland Water Factory

    The Gippsland Water Factory (GWF) is being implemented to reclaim domestic and industrial (pulp and paper) wastewater to provide a reliable and sustainable industrial water supply, replacing the high quality raw water currently provided by Gippsland Water. A grassroots facility, the GWF will process domestic wastewater by preliminary treatment, primary sedimentation, membrane bioreactor (MBR) ...

  • Case study: Municipal WWTP

    OverviewThe municipal WWTP at Monclova, Mexico had to increase its capacity by a factor of 1.5 and improve nitrification capacity, for 100% reuse by industry.  RequirementsThe city of Monclova operates a modern wastewater treatment plant which receives urban and industrial wastewater. A retrofit for an increase of 50% in capacity was required, as well as improvement in ...

  • Structural Fabric Cover Minimizes Odor Emissions for Municipal Wastewater Facility

    As municipal and industrial wastewater facilities find them-selves being ever more tightly squeezed by encroaching neigh-borhoods, the minimization of odor emissions becomes a critical operating issue. This was the problem facing the Municipal Authority of Wyomissing in Reading, Pa., operating a 4 million gallon-perday wastewater treatment facility. Located right within the community, this ...


  • Fish community responses to multiple municipal wastewater inputs in a watershed

    Municipal wastewater effluent (MWWE) is one of the largest anthropogenic waste discharges by volume in Canada and there is concern over the potential impacts it may have on aquatic ecosystems (Environment Canada 2001). The input of organic material and nutrients from MWWEs into the aquatic receiving environment can result in eutrophication and lower dissolved oxygen content (Chambers et al. ...
