“…L -1 ; however, the authors achieved less VFA yield at the examined maximum OLR (715 mgCOD . L -1 ), indicating that elevated OLRs can lead to high VFA production but it is also crucial to optimize operating OLR during the treatment of low strength wastewater in AnMBR [30]. In high-rate bioreactors such as UASB and AnMBR, VFAs may not be efficiently converted to methane due to low-retention times and can accumulate in the reactor and thus can be detected in the effluent [1,31].…”

Long term operation of an anaerobic membrane bioreactor (AnMBR) treating municipal wastewater was investigated in a real seawater intrusion spot in Falconara Marittima (Central Italy) on the Adriatic coastline. Changes in biological conversion and system stability were determined with respect to varying organic loading rate (OLR) and high salinity conditions. At an OLR of 1 kgCOD . m 3-1 d -1 , biogas production was around 0.39 ± 0.2 L . d -1 . The increase of the OLR to 2 kgCOD . m 3-1 d -1 resulted in the increase of biogas production to 2.8 ± 1.5 L . d -1 (with 33.6% ± 10.5% of CH4) with methanol addition and to 4.11 ± 3.1 L . d -1 (with 29.7% ± 11.8% of CH4) with fermented cellulosic sludge addition. COD removal by the AnMBR was 83% ± 1% when the effluent COD concentration was below 100 mg O2 . L -1 . The addition of the fermented sludge affected the membrane operation; significant fouling occurred after long-term filtration, where the trans-membrane pressure (TMP) reached up to 500 mbar. Citric acid solution was applied to remove scalants and the TMP reached the initial value. High saline conditions of 1500 mgCl -. L -1 adversely affected the biogas production without deteriorating the membrane operation. The treated effluent met the EU quality standards of the D.M. 185/2003 and the new European Commission Resolution for reuse in agriculture.

“…Basically this mechanism was doing some filtration from any molecules or particle that needed to clean up and make the water in better quality. The MBR process was has a better value in efficiency of sludge process and get better value for money for the long time installation but at the first built it costing more higher than the conventional water treatment process [15][16]. Using of MBR mechanism can combining with another mechanism that depends on the condition of the water that will treatment in MBR such as palm oil wastewater using MBR combining with baffled air flotation or biofouling reducer or domestic wastewater using MBR combining with membrane fouling [17,18,19].…”

The number of clean water needed will always increase when the number of the population still shows growth. It must have the same level from the supply and demand or the supply of clean water has higher than the demand for clean water. Some cities in Indonesia have problems with the fulfilment of clean water. Factors from climate change, behaviour, and management can affect the conditions of clean water resources. The development of technologies and science makes the reuse of the water process can be done for another resource of clean water fulfilment. Rainwater harvesting, membrane bioreactors, reverse osmosis, and filtration systems are some kind of processing systems for the water mechanism for the fulfilment of clean water. Sustainable clean water resources and supply is one of the indicators of sustainable development goals. This research was conducted to see how is the potential of water reuse for the fulfilment of clean water in Indonesia by using several systems or processing that have been installed and used. The control and evaluation is the best key to make sure the clean water resources still in the best condition and water reuse is one of the plan to support fulfilment of clean water.

“…A membrane bioreactor (MBR) consists of an activated-sludge unit and a membrane separation unit. MBR is a smart option for water treatment, as studied and reviewed by Ngo’s group ( Cheng et al., 2018 ; Khan et al., 2018 ; Yu et al., 2018 ), showing efficient wastewater treatment, small space requirement, effective solid-liquid separation, and many other advantages. The performance of MBR largely relies on the behaviour of microorganisms, where there is a tendency of decreased biodegradability and increased biofouling upon environmental shocks ( Tan et al., 2017b ).…”

Disinfectant-containing wastewaters have been generated from many places, including marine industries. The synthetic NaClO-containing wastewaters have been effectively treated in a saline MBBR-MBR (moving bed biofilm reactor & membrane bioreactor) system containing marine microorganisms. A low concentration of NaCl (below 100 mg/L) is not enough to kill the microorganisms, but can affect their bioactivity and induce membrane biofouling. A linear relationship has been obtained for the half-life of membrane biofouling as a function of the NaClO concentration (10–100 mg/L): [half-life] = 25–0.12 × [NaClO concentration]. The COD and NH 3 –N removals are the highest at a salinity of 30 g/L for the marine bioreactors. The behaviour of the typical biofoulants, measured real-timely by fluorescence spectroscopy, can indicate the levels of membrane biofouling and microbial activity, responding to the NaClO and NaCl influences. Based on the behaviour of biofoulants, this work has also proposed a novel strategy of biofoulants monitoring for membrane antifouling, where antifouling responses can be carried out when the concentration of biofoulants significantly increases.
