Abstract

Chapter 3 OJI conditioning and dewatering is very qualitative. A brief discussion on the chemical conditioning process (mainly via polymer addition) is presented, but information on how to evaluate optimal polymer choice of polymer dosage is lacking. A list of different dewatering technologies is presented but without suficient design information, except for a range in expected effluent suspended solids concentrations. Case studies are included, but again lack detail.Chapter 4 on digestion presents a good comparison between traditional aerobic, anaerobic, and autothermal thermophilic digestion (ATAD) processes. ATAD is the only process that can be used as a technology to further reduce pathogens (PFRP). Adequate process design information on any of the processes is absent, neither are quantitative criteria presented for the evaluation of system performance. An illustrative comparison on the design and capital cost of the 3 different digester processes is presented, but is hampered by the absence of a defined design goal.Chapter 5 on composting is again very

The Application of Membrane Bioreactor for Greywater Treatment

“…Additionally, this technique is significantly more sophisticated than conventional treatment methods, which are unable to handle wastewater with continuously variable water discharge. MBR can help improve the quality of domestic wastewater, such as grey water, which is typically treated using more conventional methods despite having lower quality (Banaszak et al, 1998;Liberman et al, 2016). The use of MBR is increasing even though the investment and operating expenses with this MBR performance are higher than those of conventional processing technology (Banaszak et al, 1998;Le-Clech et al, 2006).…”

The use of MBR is increasing even though the investment and operating expenses with this MBR performance are higher than those of conventional processing technology (Banaszak et al, 1998;Le-Clech et al, 2006). This is because the effluent from recycling grey water is of such high quality that it may be utilized to supplement increasingly scarce pure water sources.…”

“…However, to achieve an effective and efficient concentration reduction performance, it is necessary to determine how suitable technology is applied to grey water (Gürel and Büyükgüngör, 2015;Liberman et al, 2016). Adding a recycling processing facility usually requires a sizable quantity of space, yet there is typically relatively limited land available in urban areas (Banaszak et al, 1998;Rodrigues et al, 2023). The use of the Membrane Bioreactor system is one of the technologies that might be developed for this purpose.…”
