“…DM layer has an important role in particles rejection in anaerobic dynamic membrane bioreactors (AnDMBRs) (Ersahin et al, 2014).

“…Table 4 shows the filtration performances obtained in different AnMBRs applied for VFA recovery. Different strategies such as air/ozone backwashing and cross flow velocity were reported in the literature to control fouling and enhance permeate recovery (Kim et al, 2005;Kim & Jung, 2007). Kim and Jung (2007) applied intermittent air and air/ozone reciprocal backwashing modes during the recovery of VFA.…”

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.

Ceramic Microfiltration Membranes in Wastewater Treatment: Filtration Behavior, Fouling and Prevention

et al. 2020

View full text Add to dashboard Cite

Nowadays, integrated microfiltration (MF) membrane systems treatment is becoming widely popular due to its feasibility, process reliability, commercial availability, modularity, relative insensitivity in case of wastewater of various industrial sources as well as raw water treatment and lower operating costs. The well thought out, designed and implemented use of membranes can decrease capital cost, reduce chemical usage, and require little maintenance. Due to their resistance to extreme operating conditions and cleaning protocols, ceramic MF membranes are gradually becoming more employed in the drinking water and wastewater treatment industries when compared with organic and polymeric membranes. Regardless of their many advantages, during continuous operation these membranes are susceptible to a fouling process that can be detrimental for successful and continuous plant operations. Chemical and microbial agents including suspended particles, organic matter particulates, microorganisms and heavy metals mainly contribute to fouling, a complex multifactorial phenomenon. Several strategies, such as chemical cleaning protocols, turbulence promoters and backwashing with air or liquids are currently used in the industry, mainly focusing around early prevention and treatment, so that the separation efficiency of MF membranes will not decrease over time. Other strategies include combining coagulation with either inorganic or organic coagulants, with membrane treatment which can potentially enhance pollutants retention and reduce membrane fouling.

“…Under the same concentration, but pH of 5.5, VFA recoveries ranged from 23% to 73%. Mostafa (1999) Kim et al (2005) published research about the filtration performance of ceramic membranes to recovery VFA from sludge in a working system with capacity of 76 liters, which included an anaerobic fermenter, a micro-ceramic filtration module, a sludge container and a VFA container. The authors concluded that the optimal membrane size should be around 1 µm 23 to allow 80% recovery of the VFA.…”

“…According to Alkaya et al (2009), the liquid-liquid extraction technique to recovery VFA from fermentation broths is one of the most efficient, economical and environmental method for the separation of carboxylic acids, with recovery ratios reaching up to 98%. Kim et al (2005) published research about the filtration performance of ceramic membranes to recovery VFA from sludge and concluded that the optimal membrane size should be around 1 µm to allow 80% recovery of the VFA. This dissertation estimates a recovery ratio of 85% by using ceramic membranes for microfiltration.…”
