The demand for water supply is expected to be raised significantly in forthcoming decades. Production of reusable water from industrial and domestic wastewater is a feasible, cost effective and significant positive benefit to the environment. In the present study, the domestic rice gruel wastewater (RGW) was treated with aqueous methanol coagulation integrated aerobic membrane bioreactor (AMBR). Initially, the RGW which is at room temperature was treated with spiral wound hydrophilized - ultrafiltration (HF – UF) 5 kDa membrane module to determine the removal efficiency. Furthermore, the RGW was pre-treated with various coagulants such as methanol, ethanol and HCl. The obtained pre-treated RGW was subjected to the HF – UF 5 kDa side stream AMBR for production of reusable water. The experiments were conducted to determine the turbidity, conductivity, total dissolved solids (TDS) and chemical oxygen demand (COD) were found to be 96 %, 91 %, 91 % and 94.6 %. The overall process was feasible, compact, environmental free, cost effective, eco-friendly.

“…Different types of inorganic (Al2(SO4)3 and FeCl3) and organic (polyacrylamide) coagulants have been attempted for lab-scale direct MF/ UF of municipal wastewater (Gong et al, 2017;Huang et al, 2017;Jin et al, 2016;Jin et al, 2017). The research findings highlighted that the use of all tested coagulants in direct MF/ UF processes led to an increase in membrane performance, compared to those without coagulants.…”

“…Although a stronger cake layer containing adsorbents increased the filtration resistance, it tended to significantly decrease the irreversible fouling, thus leading to a reduced overall fouling (Gong et al, 2017). The coupling of intermittent aeration and coagulation was also attempted (Jin et al, 2016). In this combination, the coagulant helped produce loose and porous flocs and intermittent aeration helped control the thickness of such a porous cake layer on the membrane, therefore achieving a slower decline of membrane permeability.…”

Direct membrane filtration (DMF) of municipal wastewater offers an alternative solution for centralized and decentralized wastewater treatment in Iceland. The efficiency of biologicalbased wastewater treatment is restricted in Iceland, due to low temperatures and high wastewater inflow rates with extremely low concentration of organics. This study aims to investigate membrane fouling mechanisms and mitigation approaches during DMF of municipal wastewater. The DMF experiments were performed using a crossflow flat sheet membrane filtration cell integrated with an optical coherence tomography (OCT) imaging system. The effects of membrane material, operation conditions and cleaning protocol on DMF performance and foulant composition were examined. The threshold flux testing results indicated that a PVDF membrane (0.08 μm) was suitable for DMF of wastewater. Increasing crossflow velocity, physical flushing frequency and flushing water temperature contributed greatly to mitigate fouling. During a continuous DMF process, reversible fouling was predominant, while during intermittent DMF with periodical physical cleaning, irreversible/ irremovable fouling was dominant. A possible shift of tightly attached cake layer to irreversible/ irremovable fouling was revealed by the direct observation of fouling via OCT. The foulants autopsy indicated that a combination of organic and inorganic foulants was attributed to membrane fouling, instead of biological fouling. Under the optimized filtration condition, sustainable long-term DMF operation (~230 h) was achieved by employing a combination of periodical physical flushing with chemical-enhanced flushing. The water quality analysis showed that the DMF process could efficiently remove solids and greater-sized soluble organics, allowing the treated water to meet wastewater discharge standards.
