  • Recycling of Urban Sewage through cladoceran culture system

    The feasibility of using Urban Sewage (US) was tested in static water holdings for the culture of Daphnia, a cladoceran that is used as a live fish food. US was diluted to 60% (D40), 50% (D50), 40% (D60) and 30% (D70) by adding normal freshwater to constitute a total volume of 15 litres. Each culture medium (in triplicate) was inoculated with four units of Daphnia sps. per litre. The population ...

  • Analysis of Sewage and Sewage Sludge by Simultaneous ICP Spectroscopy

    In recent years, the development and expansion of sewage treatment facilities has resulted in increased amounts of sludge which is generated in the treatment process, and which has presented a problem due to processing of the sludge itself. Sludge is normally incinerated or solidified and then disposed of in landfills or recycled for use in construction materials such as concrete or ...

  • Anaerobic thermophilic digestion of sewage sludge with a thickened sludge recycle

    The process of anaerobic thermophilic digestion of municipal wastewater sludge with a recycled part of thickened digested sludge, was studied in semi-continuous laboratory digesters. This modified recycling process resulted in increased solids retention time (SRT) with the same hydraulic retention time (HRT) as compared with traditional digestion without recycling. Increased SRT without ...

  • Recycling of Municipal Wastes in Agriculture. I. Sewage Sludge Application to Corn Crop

    Abstract A two year’s field experiment (1995 and 1996) was conducted on a Typic Xerofluvent in order to study the influence of sewage sludge application on corn yield and nutrient uptake. Treatments included control (no sewage sludge, no mineral fertilisation), mineral fertilization (no sewage sludge) and sewage sludge application in total rates from 50 to 130 ton.ha-1 dry sewage sludge, applied ...

  • Management of sewage sludge and ash containing radioactive materials

    Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

  • Co-composting of sewage sludge and municipal solid waste

    Israel production of sewage sludge and MSW grows each year due to the increasing number of modern Wastewater plants that are using activated sludge process and the increasing population. Non-stabilized Sewage sludge is an environmental nuisance due to high level of pathogens, offensive odours, insect attraction and potential water sources pollution. The Haifa region itself, where the study took ...

  • Gatineau Sewage Treatment Plant, Gatineau, Quebec, Canada

    Project No. 1 Industrial Boiler Application A FLU-ACE waste heat recovery system installed to process all flue gases from three boilers. The system recovers up to 3.5 mmBTU/h of waste heat which is re-used for heating the digester sludge. The main fuel for the boilers is recycled methane based sewage gas generated from the plant’s anaerobic digesters. 'The installation ...

  • Purification of domestic sewage by water-hyacinth (Eichhornia crassipes)

    Sewage management is posing serious techno-economic problems in cities, particularly in developing countries. A new technology, sewage purification by water-hyacinth (Eichhornia crassipes), is a possible solution. This paper studied the suitability and effectiveness of water-hyacinth in treating domestic sewage. A 28-day experiment was performed under a controlled environment of a screen-house ...

Overcoming the difficulty of the waste tire recycling, initiate to handle waste tire to 40-200 mesh fine rubber powder at room temperature, which indicated that Chinese industrial ...

  • Wastewater Recycling Project

    Durban is part of the eThekweni Municipality, located on the east coast of South Africa. The combination of limited water resources in the city along with sewage capacity constraints, led to the investigation of different wastewater recycling processes since the region produces approximately 450million litres of wastewater per day. The project was South Africa’s first private wastewater ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • Characteristics and potential uses of sewage sludge in the commercial capital of Bangladesh

    Based on contrasting properties, sewage sludge can be co-recycled in order to take simultaneously the best profit and minimise environmental pollution. The present study was conducted to assess the physical and chemical properties of sewage sludge generated from different sources in the commercial capital of Bangladesh and on the basis of these characteristics a variety of ways had been fixed to ...
