  • Case study - Procurement and installation of a Biogas desulphurization unit at the Chania WWTP

    A proposal based on Bioconservacion’s technology was selected as the winning bid in the public tender released in 2015, covering the design, procurement and construction of a biogas desulfurizing unit to be installed in the waste water treatment plant in Chania, Greece. With a population over 100,000, Chania is the second largest municipality in the Greek island of Crete. Its waste water ...

  • Wastewater treatment in an anaerobic filter using small lava stones as filter media without temperature control

    For their simplicity and using cheap support materials, biological filtration of municipal wastewater can be adequate for developing countries where the legislation is not as strict as in other countries, like the members of the European Union. Biological filters are fixed biomass reactors where the suspended pollutants can easily be retained and the dissolved substances can be transformed by ...

  • High rate anaerobic thermophilic technologies for distillery wastewater treatment

    ABSTRACTIn this paper, performance of two high rate technologies, upflow anaerobic fixed-film reactor and fluidized bed laboratory-scale, treating distillery wastewater (wine vinasses ) at anaerobic thermophilic conditions have been compared. The results obtained show that the stationary packed bed, with a corrugated plastic support, operated under stable conditions at organic loading rates ...

  • Evaluation of Tire Derived Rubber Particles for Biofiltration Media

    ABSTRACTCurrently, on average, one tire is discarded in the U.S. for every man woman and child every year. While the reuse market for used tires has increased over the years to approximately 75%, there are still an estimated 2-3 billion used tires stockpiled in the U.S. Finding economical and sustainable end uses for this tire material is an ongoing challenge to environmental engineers and ...

  • Investigation of options to remove the fat based deposits in the anaerobic digestion facility

    1.0 Introduction The effluent from Greencore is treated by a hybrid AD facility which incorporates UASB granular sludge bed and fixed film media technology. The plant is not designed to treat fats, oils and greases and the presence of fats, oils and grease (FOG) has two detrimental effects on plant performance, namely; FOG’s coat the UASB sludge granules causing then to ...

  • Comparative study on toxicity evaluation of anaerobically treated parboiled rice manufacturing wastewater through fish bioassay

    Short term aquatic bioassay has been developed into a useful tool in water quality management. These tests give information on comparative toxicity of several compounds. The objective of this study was to evaluate the acute toxicity of raw and anaerobically treated effluents of the parboiled rice manufacturing industry. The acute toxicity test was carried out by using the fish Lebistes ...

  • Comparing the efficiency of uaff and uasb with hybrid reactor in treating wood fiber wastewater

    Some industrial wastewaters such as pulp and paper mills and chemicals are highly loaded with organic pollutants and can be treated advantageously by means of anaerobic processes. Anaerobic treatment converts the wastewater organic pollutants into a small amount of sludge and a large amount of biogas. Several operational problems have normally been experienced in both suspended growth and biofilm ...

  • Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment

    Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these two ...

  • The use of sewage sludge compost for improving reedbeds performance

    In a wastewater of medium strength, about 75 % of the suspended solids and 40 % of the filterable solids are organic in nature. The parameter used for measuring the strength and the quantity of the organic substances in the wastewater is the Chemical Oxygen Demand (COD) (Aggelakis and Tchobanoglous, 1995; Tchobanoglous and Burton, 1991). Degradable organic matter in wastewater, whether soluble or ...

  • Waste Water Treatment Processes Explained

    SUNCOAST WASTE WATER MANAGEMENT  presents  AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...

  • Optimization of a mainstream nitritation-denitritation process and anammox polishing

    This paper deals with an almost 1-year long pilot study of a nitritation-denitritation process that was followed by anammox polishing. The pilot plant treated real municipal wastewater at ambient temperatures. The effluent of high-rate activated sludge process (hydraulic retention time, HRT = 30 min, solids retention time = 0.25 d) was fed to the pilot plant described in this ...

  • Decentralized wastewater management in Kieu Ky Vietnam

    1. Overview and Key Points In order to eliminate the common ‘out of sight out of mind approach’ in sanitation, whereby sewers and/or drains are discharged into rivers, a Decentralized Wastewater Treatment System (DEWATS) was designed and implemented in Kieu Ky to treat wastewaters arising residential properties and various craft industries. A clear understanding of topography, ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations. In some instances, these plants were built to service tourist destinations, often in somewhat rural areas where recycling is difficult and landfills are distant. In several other cases, public agencies built plants to extend ...
