“…The response surface and contour plots were generated for different interactions of any two independent variables, while holding the value of the other variables as a constant [4]. The optimization of process variables was aimed at finding the levels of independent variables, which would give maximum percentage of total removal for COD and phosphorus removal.…”

“…This is due to the capability of RSM in estimating the effects of several factors and examining optimum conditions for desired responses [11]. Several studies also employed RSM in SBR for the textile dye wastewater treatment [4], palm oil mill [6], synthetic wastewater [12] and has shown good results of modeling. From the identified model, it can be seen that there were some limitation in measuring the dynamic of the biological process [13].…”

“…Sequencing batch reactor (SBR) is a modified activated sludge process that has been applied for numerous wastewater treatment plants such as soy sauce [1], dairy [2], industrial estate [3], textile [4] sewage, synthetic wastewater [5], palm oil mill effluent (POME) [6] and so on. This system is operated in a single reactor and it has five basic operating modes including fill, react, settle, draw and idle [7].…”

“…According to S. Sathian et al [4], a good statistical model should have R 2 value closes to 1.0. In this case, the predicted R 2 value for total removal of COD and phosphorus responses was in reasonable agreement since the fit of the model was found to be 0.977 and 0.91 respectively.…”

This paper proposes an improved optimisation of sequencing batch reactors (SBR) for aerobic granular sludge (AGS) at high temperature-low humidity for domestic wastewater treatment using response surface methodology (RSM). The main advantages of RSM are less number of experiment required and suitable for complex process. The sludge from a conventional activated sludge wastewater treatment plant and three sequencing batch reactors (SBRs) were fed with synthetic wastewater. The experiment were carried out at different high temperatures (30, 40 and 50°C) and the formation of AGS for simultaneous organics and nutrients removal were examined in 60 days. RSM is used to model and to optimize the biological parameters for chemical oxygen demand (COD) and total phosphorus removal in SBR system. The simulation results showed that at temperature of 45.33°C give the optimum condition for the total removal of COD and phosphorus, which correspond to performance index R 2 of 0.955 and 0.91, respectively.

Biological methods are used for treatment of municipal wastewater. These processes can be conducted in various kinds of technological systems. In the paper the comparison of characteristic of activated sludge from two types of technological systems is shown. A flow bioreactor with secondary settling tank (system I) and sequential bioreactor (system II) were used. The study showed, that more favorable operating conditions of activated sludge were in the SBR reactor. The activated sludge in SBR reactor had better sedimentary properties, as indicated by values of sludge volume index and flocs’ sizes. This can be connected with the fact that sludge in SRB reactor is not pumped (what occurs in flow systems). Therefore the sludge is not subjected to unfavorable conditions during hydraulic transport (flocs do not undergo the dispersion). Moreover the values of flocs’ sizes, respiratory activity and specific surface area of sludge from II system were higher in comparison with system I.
