  • Wastewater treatment for a municipality

    Description of the plant At first, wastewater is pre-treated by a combinated sand and fat trap before further treatment is affected by a special screen. The accruing particles are collected in anti-septic plastic bags to avoid any personal contact because of hygienic reasons. Based on the high varying hydraulic amount of wastewater, an aerated mixing and balancing reactor is ...

  • Mechanical biological treatment for municipal solid waste

    A major portion of municipal solid waste (MSW) is dumped in unsanitary landfills in India. To protect the environment, there is an urgent need to develop a technology which could handle the increasing MSW quantities and enhance resource recovery. Mechanical biological treatment (MBT) is considered a potential method for dealing with heterogenous MSW. Proper mechanical sorting can make the ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Bioaugmentation/waste water treatment in municipal WWTP - Case Study

    What is it? The bioaugmentation is an innovative technology which consists in an increase of selected bacteria to help naturally the biological process of organic compounds degradation. It is proper to dose in any effluent type and wastewater treatment system, which no longer has enough capacity or has an inefficient performance. These products facilitate the reduction ...

  • On the pre–treatment of municipal organic waste towards fuel production: a review

    Lignocelluloses are the main constituents of municipal organic waste (MOW). In order to increase the production of fuels, via fermentations, the enzymatic hydrolysis is the first step towards a valorisation process. It is well–known that the hydrolysis of lignocelluloses is not very effective because of the high stability of the constituents. In this respect the pre–treatment of MOW is necessary ...

  • Why municipal wastewater treatment is important?

    Municipal Wastewater Treatment is the process of ejecting the harmful pollutants from wastewater. The main source of pollutants is the domestic use. The pollutants are treated by various methods like Physical, Chemical, and Biological process. The practice of municipal wastewater treatment is best encouraged these days. This treated resource is best for utilizing in raising the ...

  • 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 ...

  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Evaluation of a sequential aerobic?anaerobic treatment of municipal solid waste in a bioreactor landfill

    A sequential aerobic-anaerobic bioreactor landfill was operated and monitored over a period of 184 days. The bioreactor was filled with 120 kg of organic fraction of Municipal Solid Waste. Leachate recirculation was applied. The results showed rapid degradation of organic matter with rapid settlement during the aerobic period. The initial COD and BOD5 were ...

  • Atmospheric impact of a municipal wastes incinerator

    This paper presents a case study of an air pollution dispersion model for the atmospheric impact assessment of a new municipal wastes incinerator (MWI). The capacity of the present MWI will increase more than ten times, and a new high-efficiency flue gas treatment system is projected. The environmental impact study has been focused on the long-term aspect of the air pollution (chronic pollution) ...

  • Assessment of leachates from a Cuban municipal solid waste landfill: characterisation and treatment

    Calle 100 landfill receives 75% of the solid waste of Havana. In this work, the physical-chemical and microbiological evaluation and the treatment of its leachates was carried out. The study of the elimination of pollutants was carried out at laboratory scale. The characterisation showed an important content in organic substances of high molecular weight, fulvic and humic acids that have a ...
