  • Sludge Treatment and Disposal Technologies

    Most wastewater treatment processes produce a by-product that purifies wastewater before it is released into local waterways. This by-product is named as sludge. Typically in solid, semi-solid or liquid state, it is in fact an amalgamation of all the liquid wastes that are discharged by domestic houses, commercial properties, industry, and/or agriculture after aerobic biological treatment. ...

  • Major meat-process plant in Canada case study

    In the meat-process plant in Canada managed by a world's leading meat-process plant, huge amount of sludge disposal cost had been a longstanding problem. In production process, approximately 96m3 sludge had been generated a day, and the sludge had been disposed by a waste disposal firm. This sludge disposal cost had reached as much as 93.6 million yen a year. The existing belt press had produced ...

  • Take it away: the need for designing fecal sludge disposal services for single-pit latrines

    The government of Bangladesh is increasingly paying attention to the safe collection and disposal of fecal sludge from pit latrines in rural areas. In this paper, we report on current sludge disposal practices from single-pit latrines, by conducting a survey of 1,091 households with pit latrines in a rural subdistrict of Bangladesh. Almost all households were using their pits, and 90% reported ...

  • Clean production in stone cutting industries

    The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to ...

  • Sustainable sludge handling for the 21st Century

    Purification of municipal and industrial waste waters leads to the generation of a residue-called “excess sludge”. This material when mechanically dewatered is typically 75-90% water. The balance of the dewatered sludge consists of organic compounds (solid waste, biomass) and inert materials (sand, salts, and metals). These sludges have been to date dehydrated to reduce the aqueous fraction using ...

  • Recovering oil from grinding sludge - Case Study

    Zahnradfertigung Ott uses RUF briquetting unit A large volume of sludge is produced in the grinding of high-precision gears. In most cases, this grinding sludge is disposed of at high costs. Zahnradfertigung Ott, a specialist manufacturer of gears, found a better solution: since 2005, the company is using a briquetting unit from RUF to recover 500 litres of grinding oil per day from the ...

  • Environmental sludge treatment

    During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

  • Sustainable wastewater treatment chemicals in a chicken processing plant

    Atana Ltd was invited to evaluate the potential for introducing an organic, sustainable wastewater treatment regime into a chicken processing plant. The flow was approximately 120m³ (over 18 hours per day). The plant killed around 126000 birds per day and the sludge volume produced from their effluent treatment plant (which encompassed dissolved air flotation) per annum was around 13000 ...
