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...
The pulp and paper industry generates large volumes of highly heterogeneous waste waters containing compounds from wood or other raw materials, process chemicals and compounds formed during processing.
The brewing process generally generates unique, high-strength waste water as a by-product. The waste water typically has a high concentration of Biological Oxygen Demand (BOD) form the carbohydrates and protein used in brewing beer. Brewery waste water usually has a temperature of > 25 °C.
Due to the diversity of products in the beverage industry, there is also a great variation in waste water composition (flow and load) from this type of industry. This requires special attention and tailor made solutions for the design of a waste water plant for this industry.
Industrial wastewater characterized by an high COD content are an interesting renewable source for the Food and beverage industrial sector which can have them readily available from their industrial processes.
The COD contribution in the wastewater can be easily converted in biogas and then in green energy to reuse inside the factory as both electrical energy and thermal energy.
This process can be applied with the installation of the UASB technology, implemented by Hydroitalia - Colsen in new and existing plants.
The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. Typical streams from these industries that can be treated are, whole...
Glass fused to steel tank is made by a special process, called vitreous enamel coating ,which is an advanced technology for anti-corrosion purpose of steel plate. Tanks are coated both inside and outside with enamel .Today, glass fused to steel tank is widely used in wastewater treatment projects as aerobic and anaerobic reactors of UASB,EGSB,SBR,BAF,USR,CSTR, and equalization tank, clarifier, and sludge holding tank. It has proven its superior resistance to thermal and chemical when facing water with extremes in...
In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time.
