    Technologies for Wastewater Treatment in Meat Processing Industry

    The main problems of wastewater treatment in poultry slaughterhouses are high energy consumption, high maintenance costs and complex treatment of highly contaminated wastewater. The objectives of wastewater treatment in slaughterhouses are to respect the legal limits, produce the minimum possible quantity of sludge and to recover the maximum possible quantity of energy. Fluence employs the following main technologies to design Waste & Wastewater treatment plants: DAF Dissolved Air Flotation: For the initial...

    Technologies for Wastewater Treatment in Dairy Industry

    Dairy industry faces the challenge of the disposal of many by-products from the production process, such as Whey, Hot Whey, Buttermilk and cheese processing wastewater. Our cost-effective solutions allow taking advantage of all the by-products, which either are a cost or have low value, thanks to the generation of biogas. The most common treatments are either Anaerobic treatment only with a medium-low biological plant, or a Dissolved Air Flotation followed by a high load biological plant. The benefits are the...

    Technologies for Wastewater Treatment in Breweries

    The "ideal" treatment of waste from beer (and not only) must respect the legal limits, produce the minimum possible quantity of sludge and recover the maximum possible amount of energy. Fluence offers an anaerobic solution on wastewater and sludge + aerobic wastewater treatment. The anaerobic solution uses a "Rapid" granular sludge digester. It is a digester in which a particular type of sludge capable of "granulating" grows and it is used for very low COD (> 2000 ֺmg / l) as long as the waste contains sugars or...

    Oxygen Monitoring from Aerobic and Anaerobic for determination of biodegradation kinetics by respirometry

    Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentration of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen uptake.

    Oxygen monitoring from aerobic and anaerobic for biodegradation tests

    Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.

    Oxygen monitoring from aerobic and anaerobic for biomass activity tests

    Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.

    Oxygen monitoring from aerobic and anaerobic for toxicity test

    Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

  • Wastewater treatment solutions for anaerobic sludge digestion sector

    Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy. It is widely used as part of the process to treat wastewater, like Upflow Anaerobic Sludge Blanket (UASB) reactors. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digestion is widely used as a renewable energy...

  • Hydrogen Sulfide (H2S) monitoring

    Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...

  • Waste water respirometry solutions for toxicity reduction tests

    In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

    Food industry is one of the world`s largest industries. Vegetable, fruit, grain, meat and other animal foods are being processed, packaged and placed on the market in different ways in factories. Large amounts of water are spent in these treatment processes and high pollution load of wastewater occurs. Also in recent years, it was observed that the amount of waste water of food industry was increased in parallel to the rapidly increasing food production. Biological treatment, which is the most effective method...
