. Calculation shows that in the prevailing conditions 1314 m3 of Methane gas per day could be collected as a byproduct which could be used either as a fuel or to produce approximately 125 kWh electricity. Volumetric hydraulic load and hydraulic retention time 32. UASB REACTOR FS-BIO-009 Page 3 of 9 INDEX 1.
The discrepancies in the initial UASB plants were recorded and now a new breed of UASB reactor is available with respect to the design. The temperature range which affects solid retention time and the flow fluctuations which affect the upflow velocity are also considered. 3 kg COD m d kg CODd 2 98 m s 0002 m 3 1020.
Effluent from food industry with 336 plants was the most common followed. Flow measurements should be part of continuous process control. This Excel spreadsheet can be used to calculate the required UASB reactor volume and dimensions sludge production rate methane production rate and required alkalinity addition based on user input information on wastewater flow and characteristics.
The UASB was designed to treat the fruit waste water anaerobically for biogas generation. With 793 plants it accounted for 645 of the total number of reactors Hulshoff Pol et al 1998. Influent distribution system 36.
An Upflow Anaerobic Sludge Blanket Reactor was. 70 Accordingly this leads to 20 COD reduction due to precipitation and the solids get settled in the Primary Cla - rifier. Table 1 also summarizes the number of installations for eight types of industrial effluents including solid wastes and co-digestion.
In general there are two ways to design an UASB reactor If input COD. Disadvantages of anaerobic granulation include the long start-up time and the relative high operation temperature needed. Thus extremely high SRT could be maintained irrespective of HRT.
Upflow Anaerobic Sludge Blanket UASB reactors have been widely used for the treatment of industrial wastewater. This paper was reviews overall UASB technology in Mirzapur India. Upflow velocity and reactor height 34.
The reactor volume was 795 L and sludge from septic tank size 1mm was used as seed with an initial concentration of 166 g VSSL. The authors achieved the max-. Biological loading rate sludge loading rate 33.
Therefore the actual effluent parameters to the inlet of UASB Reactor are as mentioned in Table 2. Continuous Flow Stirred Tank Reactor CSTR is the common model of reactor used to treat various kind of wastewater.

Type of reactor design is UASB. The UASB reactor was used to treat sugar industry waste wa-ter at varying loading rates of 05 16g CODL and operating - period 200 days. They are necessary for the calculation of further process design and operational parameters eg.
The settling compartment is formed by the sloping hoods for gas collection. 18 ASHUTOSH SHARMA BTECH CHEMICAL ENGINEERING UASB Design calculation. March 14th 2019 - Uasb reactor design calculation pdf Get file Genitourinary side effects have included retention to increase download speeds by up to 5 times resume and schedule downloads Free shipping to and from repair facility The plan was to.
The depth of the compartment is 20 to 25 m and the surface overflow rate kept at 20 to 28 m 3 m 2 -day 1 to 12 mh at peak flow. The characteristics of treated bagasse wash water after UASB Reactor was as indicated in the Table 3. Development and modification on digester type is still ongoing till this day.
42 Other parameters 421 COD charge per volume Measurements at UASB reactors in South-America indicate a relation between the. Reactor ASBR Anaerobic contact process Anaerobic filter AF Upflow anaerobic slugde Blanket UASB Fluidized bed Reactor Hybrid reactor. Proposed Design of Upflow Anaerobic Sludge Blanket UASB for Mapúa Institute of Technology Project by.
Load 5-20 kg CODm3-d COD removal efficiency. 5000 - 15000 mgl or more the design method should be used based on Organic Loading rate OLR If input COD 5000 mgl the design method should be calculated based on velocity. An example UASB design calculations spreadsheet is partially shown in the image below.
UASB reactor efficiencies 35. Many modifications and improvements have been developed in UASB reactor to enhance their efficiency. Organic charges per volume.
A short summary of this paper. UASB reactor design and construction in past was shows quite different and the very first 5 MLD treatment capacities plant that were demonstrated and constructed at Kanpur India under the Ganga Action Plan in 80s. Full PDF Package Download Full PDF Package.
Been made to design an upflow anaerobic sludge blanket UASB type digester. The feed inlet system is next designed so that the required length and width of the UASB reactor are determined. The design features of the UASB reactor design are presented below in Table 1.
UASB reactor has been and is the most usual reactor configuration to grow anaerobic granules for COD removal. UASBAF Able to retain very high concentration of active biomass in the reactor. The most noted modification in anaerobic reactor and mostly used in the world today is Up-flow Anaerobic Sludge Blanket UASB reactor.
Upflow anaerobic sludge bed UASB reactors for the treatment of municipal sewage in Cali Colombia Lettinga et al.
