Abstract

Membrane bioreactors can be operated with intermittent permeation and continuous aeration. Aeration close to the surface of a submerged membrane helps maintain a membrane surface free from fouling. Conditions under which this occurs depend on the interaction between flux and aeration rate. Increased flux is possible without severe fouling with aeration rate. Results of membrane operation under the dual intermittence of aeration and permeation rates, with permeation also interrupted on a regular cycle, are presented. Results showed membrane plants designed for optimal operation at moderate flux can survive effectively with higher flux operation for restricted periods. Design to account for such effects could reduce overall plant costs. [on SciFinder (R)]
