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...
30 years of experience in the design, construction, and operation of waste-to-energy plants for a wide range of industrial and municipal clients. Our proprietary anaerobic treatment technologies process wastewater and sludge to produce biogas, which can b
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.
Tighter discharge consents, reduced energy consumption, reduction of CO2 emission, advanced nutrient removal from effluent, increased capacities and decentralized treatment are the modern trends that waterboards and municipalities are facing. In order to meet new standards, municipalities are looking for specialized solutions.
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...
Using Oxygen to Solve Waste Water Problems
Lack of oxygen can cause inadequate purification or even anaerobic decomposition, as well as offensive odors. Injecting oxygen into sludge beds &/or piping allows you to:
* Reduce nitrogen levels
* Meet peak O2 demands
* Have a back up to your aeration system
* Pre-purify waste water
* Control odors
* Deter corrosion damage
* Meet increased requirements regarding waste water purification
Many wastewater streams contain suspended solids that need to be disposed of or cause problems in ‘downstream’ wastewater treatment systems. Effective TSS removal is an important step to purify water sufficiently for reuse, thereby lowering the requirement for fresh water.
Sulfide Odor Control
Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...
Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a...
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...
TDA Aerator diffuser can be used in aerobe and an-aerobe phase of (waste-) water treatment(wwtp) at all sort of industries. Ideal for biological treatment aeration and reliable for the treatment of industrial wastewater or sewage water.
the perforated surface of the membrane sleeve makes tube diffusers a perfect solution for all types of chambers and applications.
The exhalation of air through the bottom grooves decreases the depositing of activated sludge underneath the ventilation which means less cleaning...
