There are a large number of fixed-dome anaerobic reactors, such as the Deenbandhu design [36] in India, China, and Bangladesh. These reactors operate at ambient temperatures and use cattle manure as the substrate.

Types of anaerobic reactors Low rate anaerobic reactors High rate anaerobic reactors Anaerobic pond Biogas Septic tank Standard rate anaerobic digester Imhoff tank Slurry type bioreactor, temperature, mixing, SRT or other environmental conditions are not regulated.

Anaerobic reactors differ from aerobic reactors primarily because the former must be closed in order to exclude oxygen from the system, since this could interfere with anaerobic metabolism.

A noticeable exception is constituted by anaerobic ponds and the bottom of facultative ponds, in which anaerobic conditions are established as a result of stratification and oxygen [ ].

Anaerobic digestion (AD) of organics is a challenging task under high-strength sulfate (SO 4 2−) generation of toxic sulfides by SO 4 2−-reducing bacteria (SRB) causes low methane (CH 4) study investigated the feasibility of alleviating sulfide inhibition and enhancing CH 4 production by using an anaerobic reactor with built-in microbial electrolysis cell.

The anaerobic reactor section of waste water treatment follows on from other processes. First, the waste water goes though equalization, neutralization and then a heat exchange before being pumped into the reactor tank.

Gas produced by these processes is released for treatment and can be used to produce energy using a turbine. Anaerobic Upflow Sludge Blanket Reactor Anaerobic growth forms a granular floc (1 to 3 mm). These granules are kept in suspension in an upflow reactor.

The waste enters the reactor and flows up through the sludge blanket. (Figure overhead) The gasses produced provide mixing, and also cause some of the biomass to rise, the biomass hits. This book presents a state-of-the-art report on the treatment of pulp and paper industry effluents using anaerobic technology.

It covers a comprehensive range of topics, including the basic reasons for anaerobic treatment, comparison between anaerobic and aerobic treatment, effluent types suitable for anaerobic treatment, design considerations for anaerobic treatment, anaerobic reactor. In book: Waste Water - Treatment and Reutilization Examples of applications that reflect the state-of-the-art in the treatment of industrial effluents by high rate anaerobic reactors are also.

An expanded granular sludge bed (EGSB) reactor is a variant of the upflow anaerobic sludge blanket digestion (UASB) concept for anaerobic wastewater treatment.

The distinguishing feature is that a faster rate of upward-flow velocity is designed for the wastewater passing through the sludge bed. The increased flux permits partial expansion (fluidisation) of the granular sludge bed, improving.

An anaerobic baffled reactor (ABR) is an improved Septic Tank with a series of baffles under which the grey- black- or the industrial wastewater is forced to flow under and offer the baffles from the inlet to the outlet. The increased contact time with the active biomass (sludge) results in improved are robust and can treat a wide range of wastewater, but both remaining sludge.

Upflow anaerobic sludge blanket (UASB) reactors and anaerobic baffled reactors (ABRs) are sanitation technologies that are designed to remove organic matter (measured as BOD or COD).

They can also recover methane, which can be managed to produce energy. They are considered sludge blanket reactors because the influent wastewater receives treatment by passing through. Anaerobic fixed-film reactors were developed in and have grown to represent an advanced technology that has been used effectively for treating a variety of industrial wastes.

A number of variations have been developed in the intervening years including the fully packed upflow anaerobic filter (AF), the fully packed downflow anaerobic.

Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen.

The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion.

One type of high-rate reactor is the anaerobic baffled reactor (ABR). Developed by McCarty and co-workers at Stanford University, the ABR was described as a series of upflow anaerobic sludge blanket reactors (UASBS) because it is divided into several compartments (3, 5, 16).

(Refer to Figure 1 and 2 for a schematic of an UASBS and an ABR). anaerobic reactor systems. The application potential, e.g. in the petro-chemical industries, is rapidly growing. Figure shows the gradual increase in the number of anaerobic high-rate reactors from the mid seventies onwards.

At present, a total number of 2, registered full scale installations are in operation, which are. Abstract. Different types of reactor configurations used for the anaerobic treatment of wastewaters are presented in this chapter.

Anaerobic baffle reactor (ABR) process for treating a slaughterhouse wastewater. Environmental Technology: Vol. 13, No. 9, pp. Anaerobic Baffled Reactor Anaerobic baffled reactor (ABR) consists of a number of UASB reactors connected in series.

In ABR, wastewater passes over and under the staggered vertical baffles as it flows from inlet to outlet. Unique baffled design enables ABR to reduce biomass washout, hence retain a high active biomass content.

Anaerobic sludge blanket reactors Sludge blanket reactors are a type of anaerobic treatment where wastewater is passed through a free-floating “blanket” of suspended sludge particles.

As the anaerobes in the sludge digest the organic constituents in the wastewater, they multiply and collect into larger granules that settle to the bottom of. The use of anaerobic reactors for domestic sewage treatment has increased significantly since the UASB configuration started to be efficiently applied for this purpose in the beginning of the s.

Hundreds of UASB reactors, or similar anaerobic units, are used in domestic sewage treatment systems, particularly in developing countries.An anaerobic baffled reactor (ABR) is an improved septic tank with a series of baffles under which the wastewater is forced to flow. The increased contact time with the active biomass (sludge) results in improved treatment.

The guidelines and toolbox presented in the GTZ ecosan source book aim to address the needs and interests of.Aerobic Vs Anaerobic Reactors: Advantages And Disadvantages, Basic Selection Criteria. The criteria used to select whether an aerobic process is more appropriate or if an anaerobic process is preferable are: Concentration of organic matter to be removed.

If nitrogen removal is necessary. Availability of physical space. Project OPEX and CAPEX costs.
