subject: Biological wastewater treatment [print this page] The term membrane bioreactor (MBR) makes reference to the combination of a process of active muds and separation by means of ceramic membranes.
According to the titled article "Textile waste water treatment by means of a membrane bioreactor" investigators Salazar Gmez, Crespi Rosell and Salazar (available in the Redalyc magazine, number 26, 2009) maintain that at present, is researching themselves in the membrane use for the obtaining of better yields of purification, reduction of operation and maintenance costs in the generation of processes of water purification. So that the processes own a high flexibility to support the variations in the affluent that generate a minimum mud production and that is designed in minimal conditions of area.
It is important remember that purification of waste water is pursuing a number of objectives: protect the environment, minimising pollution, maintain the quality of life of individuals, save energy and making the waste obtained.
The application of multitubular ceramic membranes coupled to a biological reactor configuring an MBR has the following advantages: concentration of solids, temperature (ceramic membranes can work at temperatures above 100), pretreatment simplicity and Recovery or Cleaning (ceramic membranes can be cleaned to temperatures of 60 - 80C, for long periods).
Porous ceramics has a number of continuous or randomly distributed pores in its interior with each pore diameter different depending on its usage. Exploiting this feature, porous ceramics can separate solid, liquid and gas. In addition, by utilizing large surface area of pores, they are capable of absorption and carrying catalysts. By forming another membrane with different function on the surface, porous ceramics can be used as a substrate as well.
