“…This research aims to compare two suspended growth process reactors for the BOD5 removal efficacy. The importance of this research is to determine which reactor works best in real time application of the organic content reduction efficiency, consumption of power and cost were analysed (Al-Shammari et al 2018). Some of the applications of innovative Membrane BioReactor and SBR are; for the leachate treatment from incineration plants and sanitary landfills, MBRs were advantageous at pollution removal, fouling control, and power mitigation of the whole treatment processes (Zhang, Xiao, and Huang 2020).…”

Aim-The aim of this research is to compare suspended growth reactors MBR and SBR to calculate the organic content reduction efficacy offered by the reactors for different concentrations of wastewater from the dairy industry. Materials and methods -The secondary treatment reactors, MBR and SBR having an average Organic Loading Rate (OLR) of 0.55 g/m³/d to 1.11 g/m³/d, were compared for their Biological Oxygen Demand (BOD5) removal efficacy for a period of 5 consecutive days for wastewater effluents from dairy industries such as mixed dairy, cheese, cheese whey, milk permeate, butter, dairy sewage, ice cream. Test samples (N = 14) were taken from the outfall of the experimental group (MBR) and control group (SBR) using G Power software. G power is taken as 0.8. Results-The performance of an individual MBR reactor at removing the BOD5 content was 95% compared to an individual SBR reactor which showed only 65%. On the other hand, the treatment plant as a whole which employed MBR reactor showed a removal efficacy of 84% and the plant which employed SBR reactor showed only 70% removal efficacy of BOD5. The significance value is determined as 0.04 (p is less than 0.027, statistically significant) based on SPSS analysis. Conclusion -MBR not only showed a better efficacy at removing BOD5 from the dairy wastewater but was also cost efficient ($7.59) than SBR ($11.53), the only downside to the MBR reactor was that it utilised more power of 62.82 kW than that of SBR (44.71 kW). MBR showed a lesser efficacy of 52% for treating the effluents from ice cream which had an OLR of 0.156 g/m³/d and the reactor showed its highest efficacy of 99.8 % for treating milk permeate effluents of having an OLR of 1.73 g/m³/d .

The dairy industry meets basic needs and has high production volumes. It cannot be ignored in terms of its potential for water pollution. Dairy industry wastewaters contain significant amounts of organic matter. Wastewater from the Pınar Milk Plant in Eskişehir Organized Industrial Zone was controlled by chemical oxygen demand, oil and grease, suspended solids and pH parameters. Microwave (MW) treatment involves a combination of MW irradiation, an adsorbent (as catalyst) and an oxidant. The effects of radiation power and time, and adsorbent and oxidant dosages on removal efficiency were investigated. Bentonite, limestone and pumice were used as adsorbents, with hydrogen peroxide as oxidant. The best organic matter removal (41.4%) was obtained with limestone, while 49% oil and grease removal was achieved with pumice. The best suspended solids removal (67%) was obtained with limestone.
