Anaerobic Digestion of Pulping Wastewater Using Up-flow Anaerobic Sludge Blanket (UASB) Reactor at Mesophilic Condition
Corresponding Author: Randa M. Osman Chemical Engineering and Pilot Plant Department, National Research Centre, Cairo, Egypt Email: [email protected] Abstract: The waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is condu...
متن کاملStart-up of Anaerobic Ammonium Oxidation (Anammox) from Conventional Return Activated Sludge in Up-flow Anaerobic Sludge Blanket (UASB) Reactor for Autotrophic Nitrogen Removal from Wastewater
A bench-scale up-flow anaerobic sludge blanket (UASB) reactor was applied to start-up the anaerobic ammonium oxidation (Anammox) process from conventional return activated sludge. The reactor was operated for approximately 170 days and was fed synthetic wastewater containing mainly nitrite ) (NO2 − and ammonium ) (NH 4 + as main substrates. After 106 days of operation, the first evidence of Ana...
متن کاملinvestigation of effective parameters on the efficiency of up flow anaerobic sludge blanket (uasb) treatment system for solid waste leachate
up flow anaerobic sludge blanket (uasb) treatment has proved its efficiency among other treatment methods especially for hardly degradable wastewaters such as industrial wastewaters and leachate. uasb is a widely used reactor with a resistance biomass. waste landfills' leachate is one of the most polluted wastewaters which cause great concerns due to landfill implementations for municipal ...
متن کاملThe Transition Stage in the Start-up of an Anaerobic Sludge Digester
The start up 
 dynamics of a one-million and two-hundred-thousand liter anaerobic digester of municipal waste treatment sludge was studied. In the digester, mixing was accomplished by circulation of the produced biogas at a rate of 0.13 m3 per hour of the digester volume per hour. During the nine-month study, no serious phenomena of foaming, getting sour, temperature fall, etc. were observe...
