“…EPS is the major contributor to membrane fouling during POME treatment with an average composition of 52% of the total foulants [50]. Also, this is in accordance to the reports on the direct relationship that exists between the EPS contained in the mixed liquor with the fouling rate [255], specific flux [256], critical flux [128], and membrane filtration performance [257]. They all confirmed that EPS constitutes majorly in the deposited foulants.…”

“…Membrane fouling could cause gross deterioration of the system performance in terms of filtration and operational energy utilization, as highlighted earlier. Therefore, the need to control the fouling is indispensable and this justified the previous studies reported on this critical area [67,110,161,[255][256][257][258]. The efforts devoted by the researchers have yielded some improvements such as membrane fouling control strategies and filtration.…”

Over the years, different types of alternative technologies have been developed and used for palm oil mill effluent (POME) treatment. Specifically, membrane bioreactor (MBR) has been employed to relegate pollutants contained in POME under different operating conditions, and the technology was found to be promising. The major challenge impeding the wider application of this technology is membrane fouling, which usually attracts high operating energy and running cost. In this regard, novel methods of mitigating membrane fouling through the treatment processes have been developed. Therefore, this review article specifically focuses on the recent treatment processes of POME using MBR, with particular emphasis on innovative processes conditions such as aerobic, anaerobic, and hybrid processing as well as their performance in relation to fouling minimization. Furthermore, the effects of sonication and thermophilic and mesophilic conditions on membrane blockage were critically reviewed. The types of foulants and fouling mechanism as influenced by different operating conditions were also analyzed censoriously.

“…Granular activated sludge systems such as self-immobilization methods have been widely applied in the area of wastewater treatment and used for the reduction of a number of organic compounds, such as phenols, alcohol and acetate. Compared to conventional sludge, self-immobilization of activated sludge has several advantages including low operation cost, good control over flocculent sludge growth and the elimination of the sedimentation tank and recycling pumps [49,94]. Granular activated sludge was used for the reduction of COD from several wastewater streams under aerobic and anaerobic systems and achieved high removal efficiency, as shown in Table 5.…”

Gas-to-liquid (GTL) technology involves the conversion of natural gas into several liquid hydrocarbon products. The Fischer–Tropsch (F–T) process is the most widely applied approach for GTL, and it is the main source of wastewater in the GTL process. The wastewater is generally characterized by high chemical oxygen demand (COD) and total organic carbon (TOC) content due to the presence of alcohol, ketones and organic acids. The discharge of this highly contaminated wastewater without prior treatment can cause adverse effects on human life and aquatic systems. This review examines aerobic and anaerobic biological treatment methods that have been shown to reduce the concentration of COD and organic compounds in wastewater. Advanced biological treatment methods, such as cell immobilization and application of nanotechnology are also evaluated. The removal of alcohol and volatile fatty acids (VFA) from GTL wastewater can be achieved successfully under anaerobic conditions. However, the combination of anaerobic systems with aerobic biodegradation processes or chemical treatment processes can be a viable technology for the treatment of highly contaminated GTL wastewater with high COD concentration. The ultimate goal is to have treated wastewater that has good enough quality to be reused in the GTL process, which could lead to cost reduction and environmental benefits.

“…This system is well suited for cost effective treatment of the dairy wastewater and it shows an efficient removal of every nutrient and organic compounds present in the dairy effluents [54]. The aerobic granular sludge treatment is efficient than the normal activated sludge system due to its strong resistance against shocks, elevated settle ability, less toxicity and higher biomass recovery [55]. The aerobic granular sludge system is used to treat the industrial effluent containing around 100-1000 mg L -1 of suspended solids in the effluent.…”

Dairy products are one of the richest sources of vital nutrients in the diet of human beings and it occupies an important place in satisfying their nutrient requirements. The dairy products possess a very short lifespan and during their decomposition create a huge nuisance to the environment. The dairy effluents discharged from the industries are mainly composed of complicated substances such as organic compounds, inorganic compounds, carbon, nitrogen, phosphorus, chlorides, sulphides, fats, oils, grease, etc. These organic loading present in the dairy effluent have a negative impact on the environment during its discharge to nearby water sources. The physical and chemical treatment of the dairy effluents is not as effective as the biological treatment. The biological treatment method is found to be the superior method for treating the dairy effluent. The biological wastewater treatment can be performed in two various conditions such as aerobic and anaerobic. The treatment methods such as aerobic lagoons, activated sludge, sequential batch reactor, trickling filter, completely stirred tank reactors, fluidized bed reactors, and anaerobic filters are some of the biological methods used in dairy effluent treatment. This review article has investigated in detail regarding the environmental impact of dairy effluents and their effective treatment using biological treatment technologies
