“…In the previous research, the use of algae macrocapsule for MBR, where algae would be place on fiber macrosphere coated with polymer were proven to be efficient in separating the wastewater with the high level of ammonia nitrogen, with a level of efficiency of 97.38% as well as the level of Chemical Oxygen Demand (COD) of 62.23, such result proved that MBR could save energy in managing non-degradable liquid waste management (33). The application of dynamic membrane with hollow fiber was reported as ultra-filtration and low-cost membrane, as well as having the ability to separate high level COD (14). Both studies could explain significant decrease of level of NH 3 N of 90.91% as well as for COD of 54.02% for the use of MBR system, at WWTP of Dr. Soetomo General Hospital, although no information has been found on the microorganisms being used.…”

“…The next method is membrane technology that have been widely used in liquid waste management where this technique utilizes the principle of separating physics and chemistry through the utilization of permeability difference. Membrane is a synthetic material with the width of < 1 mm and is semipermeable namely natural polymer deriving from cellulose (14). The Membrane Bioreactor (MBR) is an option in biological liquid waste management specifically on the liquid waste generated from the health care facilities with the ability to separate the flow of the liquid waste from the solid and nutrients.…”

Introduction: Hospitals are institutions that produce liquid waste that may pollute the environment and have a dangerous impact on health. Hospital waste has the potential to contain hazardous chemicals, pharmaceutical waste, radioactivity and microbiological pathogens in liquid waste that can pollute the environment and disrupt the balance of the ecosystem. This study aims to determine the effectiveness of the Wastewater Treatment Plant (WWTP) and the quality of the liquid waste at the Dr. Soetomo General Hospital. Methods: This research was a quantitative descriptive study using secondary data from laboratory analysis of wastewater inlet and outlet of The Central Wastewater Treatment Plant (WWTP) of Dr. Soetomo General Hospital for the January-December 2020 period. Effectiveness was obtained by calculating the difference between the inlet and outlet values of each parameter divided by the inlet value multiplied by 100%. Results and Discussion: WWTP in Dr. Soetomo General Hospital Surabaya used a central WWTP which had 3 (three) units, namely WWTP Sequence Batch Reactor (SBR), WWTP Membrane Biostrain Reactor (MBR) and WWTP Aerobic Biofilter which aims to improve the quality of liquid waste. Based on the results of the research analysis, it has been found that hospital wastewater treatment using a central WWTP system is effective for reducing the levels of parameters, namely Total Suspended Solid (TSS) by 60.55%, Biological Oxygen Demand (BOD) by 72.52%, Chemical Oxygen Demand (COD) by 54.02%, Ammoniacal Nitrogen (NH3N) by 90.91%, Phospate (PO4) by 71.43%, bacteria group E. Coli by 99.93%. The temperature and Potential of Hydrogen (pH) parameters recorded at the outlet are in accordance with the established quality standards. Conclusion: The three WWTP units used in Dr. Soetomo General Hospital are able to treat liquid waste effectively. Liquid waste at each outlet parameter is in accordance with East Java Governor Regulation No. 72 of 2013 concerning quality standards for health facilities waste water, so that the effects of contamination on the environment can be minimized.

Excess sewage sludge in wastewater treatment plants (WWTPs) is regarded the key energy source for achieving energy neutral WWTPs. The anaerobic digestion process transforms sludge-organic matter into methane, which subsequently can be used for heat and electricity production. Conventional anaerobic digesters (ADs) have been used for sludge treatment for many decades, requiring high energy and providing poor effluent quality. Anaerobic membrane bioreactor (AnMBR) technology exhibits a promising option for treatment of high solids concentration streams including sludge. AnMBRs result in an increase in digestion efficiency and enhancement in effluent quality at small footprints. AnMBRs have the potential to reduce capital and operational costs, and produce more energy in comparison to conventional ADs. Thus, energy neutral or positive operation can be achieved with AnMBRs. Besides, nutrient recovery or direct use of permeate will become more feasible in AnMBRs compared to use of sludge supernatant in ADs. However, membrane fouling can limit the feasibility of AnMBRs for sludge treatment, which requires further research. This review paper critically evaluates the current status of AnMBR technology for municipal sludge treatment discussing the effect of different factors on treatment and membrane filtration performances. Furthermore, future research opportunities to enhance applicability of this technology are addressed.

“…Membrane bioreactors (MBRs) have been widely used during the last decades for wastewater treatment worldwide in large-scale (≥10,000 m 3 /d) or even in super-large-scale (≥100,000 m 3 /d) plants, due to their various advantages, such as excellent effluent quality [ 1 ], occupation of small land area, low hydraulic retention time (HRT), higher solids retention time (SRT) and lower sludge production [ 2 , 3 , 4 ]. However, they present a major disadvantage that resides in energy consumption, which is attributed to the membrane fouling problem [ 5 , 6 , 7 ].…”

Membrane Fouling Controlled by Adjustment of Biological Treatment Parameters in Step-Aerating MBR

2021

A promising solution for membrane fouling reduction in membrane bioreactors (MBRs) could be the adjustment of operating parameters of the MBR, such as hydraulic retention time (HRT), food/microorganisms (F/M) loading and dissolved oxygen (DO) concentration, aiming to modify the sludge morphology to the direction of improvement of the membrane filtration. In this work, these parameters were investigated in a step-aerating pilot MBR that treated municipal wastewater, in order to control the filamentous population. When F/M loading in the first aeration tank (AT1) was ≤0.65 ± 0.2 g COD/g MLSS/d at 20 ± 3 °C, DO = 2.5 ± 0.1 mg/L and HRT = 1.6 h, the filamentous bacteria were controlled effectively at a moderate filament index of 1.5–3. The moderate population of filamentous bacteria improved the membrane performance, leading to low transmembrane pressure (TMP) at values ≤2 kPa for a great period, while at the control MBR the TMP gradually increased reaching 14 kPa. Soluble microbial products (SMP), were also maintained at low concentrations, contributing additionally to the reduction of ΤΜP. Finally, the step-aerating MBR process and the selected imposed operating conditions of HRT, F/M and DO improved the MBR performance in terms of fouling control, facilitating its future wider application.
