Physicochemical parameters in the membrane bioreactors. a Transmembrane pressure (TMP) and effluent flow rate; b total organic carbon (TOC) concentration; c ammonium concentration; d pH; e mixed liquor suspended solids (MLSS) concentration; f dissolved oxygen concentration. Circles and triangles denote the data for Reactors 1 and 2, respectively, and closed and open symbols denote the data detected in the sludge and effluent, respectively. The arrows in panel A indicate the day of membrane cleaning with 0.1% NaOCl; (i) Cleaning was performed on Day 15 in Reactor 1 and on Days 21, 23, and 24 (ii, iii and iv) in both reactors
