“…Previous designs of RDBC have been applied [16][17][18] although it was still rarely reported for wastewater treatment. A bench-scale RDBC adapted from the previous study [18] was used and illustrated in Figure 1. The RDBC tank was equipped with a 6 L single drum made from stainless steel mesh (mesh size = 3 mm).…”

Textile effluent could endanger human health and the water environment, but it is very challenging to be treated due to its complex composition. Biological methods for textile wastewater treatment by using fungi has been extensively studied in a lab-scale yet the investigation on a larger scale is still limited. In this study, a preliminary investigation of immobilized Trametes hirsuta D7 in light expanded clay aggregate (myco-LECA) application was conducted to treat the real textile wastewater in a rotating drum biological contactor. The undiluted wastewater without any addition of carbon and nutrients was used in the experiment and treated for 72 hours in the batch-mode bioreactor. The results revealed the maximum decolorization of 74.62% along with the highest laccase activity observed at 107 UL−1. Moreover, the pH was successfully reduced from 12.94 to 8.57 while the chemical oxygen demand still fluctuated. In terms of nutrients, 57.4% of phosphorus (PO4-P) removal was achieved but no observation of the nitrification process. Based on the toxicity assay using Artemia salina larvae, the treatment could reduce the toxicity level and performed a total chromium removal up to 36.5%. These findings showed the promising abilities of myco-LECA for textile wastewater treatment prior to the full-scale application.

“…Rotating biological contactors (RBC) rely on the rotating submerged disks to grow biofilm that is kept in constant motion for energy-efficient aeration. Longer sludge retention time (SRT) allows the growth of the nitrifying community throughout the biofilm to perform complete nitrification [ 5 ]. In RBC, sufficient microbial growth on the rotating disks exploits the benefit of high effluent quality and treatment efficiency.…”

Response Surface Methodology for Optimization of Rotating Biological Contactor Combined with External Membrane Filtration for Wastewater Treatment

A large amount of wastewater is directly discharged into water bodies without treatment, causing surface water contamination. A rotating biological contactor (RBC) is an attached biological wastewater treatment process that offers a low energy footprint. However, its unstable removal efficiency makes it less popular. This study optimized operating parameters in RBC combined with external membrane filtration (RBC-ME), in which the latter acted as a post-treatment step to stabilize the biological performance. Response surface methodology (RSM) was employed to optimize the biological and filtration performance by exploiting three parameters, namely disk rotation, hydraulic retention time (HRT), and sludge retention time (SRT). Results show that the RBC-ME exhibited superior biological treatment capacity and higher effluent quality compared to stand-alone RBC. It attained 87.9 ± 3.2% of chemical oxygen demand, 45.2 ± 0.7% total nitrogen, 97.9 ± 0.1% turbidity, and 98.9 ± 1.1% ammonia removals. The RSM showed a good agreement between the model and the experimental data. The maximum permeability of 144.6 L/m2 h bar could be achieved under the optimum parameters of 36.1 rpm disk rotation, 18 h HRT, and 14.9 d SRT. This work demonstrated the effective use of statistical modeling to enhance RBC-ME system performance to obtain a sustainable and energy-efficient condition.
