This paper is to explore the feasibility of a novel combined uncoupler of 3,3ˊ,4ˊ,5-tetrachlorosalicylanilide (TCS) and 2,4,6-trichlorophenol (TCP) on excess activated sludge reduction compared to single dose of TCS and TCP. Four sequenced batch reactors (SBR) were continuously operated during two-month period dosed by different concentration of metabolic uncoupler. The comparative experiments showed that the combined uncoupler could effectively limit sludge yield by approximately 52%, followed by TCS, TCP, without obvious affecting the TOC removal rate and SVI value. At the end of the operation, the variation of zeta potential clearly indicated that uncoupler dosing affected the flocculability of activated sludge. The study demonstrated applying a combined uncoupler was feasible and promising technique to reduce sludge yield in SBR.

Influence Of Noise

Some new experimental evidence of complex irregular oscillations in the Belousov-Zhabotinsky reaction realized in a batch reactor is presented. The results were obtained under relatively low cerium and malonic acid concentrations. One-dimensional maps were used for general discussion, and particularly, for the influence of noise on the evolution of the oscillations.
