| Title of the article | Submerged ceramic modules in biomembrane installation |
| Abstract. | The article presents the results of a study of a tubular ceramic membrane installation produced by the Russian company JSC «Genos» (Moscow) as a submerged module for a laboratory membrane bioreactor; benefits and prospects of ceramic membranes application for the MBR technology as a submersible modules for industrial wastewater treatment are substantiated. The experiments were performed on waste waters of food and pharmaceutical industries characterized by a high content of organic impurities and COD ranging from 800 to 5 000 mg/l. The membrane module performance was assessed by the flux J(l/h m2) and permeability Jn (l/h m2 bar) values, MLSS in the installation constituted 2,5 to 9,5 g/l; the installation operation was controlled by the pressure, which was changed from 0,1 to 0,3 bar, organic loading rate was kept within the limits of 1 to 2 kg COD/m3 day. The laboratory apparatus was working in a cycle mode; each cycle consisted of the following phases: feeding of waste water, waste water oxidation with membrane regeneration by air purging, pressure release, filtration, pressure release, excess sludge removal. The experiments proved high efficiency of air purging as compared with back-washing for the membrane regeneration. |
