The effect of bilge water on a Biofilm—MBR process in an integrated shipboard wastewater treatment system

Bilge Water Treatment in an Upflow Electrochemical Reactor using Pt Anode

“…Turbidity depends on the size of oil droplets, and as the droplets tend to coalesce, the turbidity decreases due to a lower number of oil droplets or an increase in their size (11). In the literature, Sun et al (5) reported the biodegradation of components by measuring the soluble COD in the biofilm reactor. The authors found that the overall organic removal rate represented by COD removal was proportional to the corresponding inlet loading rate (7).…”

“…It is known that the oil droplets could be stabilized in the emulsified oily water using surfactants by forming micelles in aqueous solutions (5,9,29,37). In the study, the mixture of diesel fuel, lubricating oil, hydraulic oil, surfactants, and salts were vigorously blended for 10 min in synthetic bilge water using high speed blender mixing system in order to avoid the oil particles from coalescing for stable emulsion.…”

“…Bilge water is a two-phase dispersive system in which water is the continuous phase, and oil is the dispersed phase (1,3,5). Dispersions of oil droplets in water, namely emulsions are known as stable oil-in-water (o=w) solutions.…”

“…The large volumes of oily wastewater generally in the form of ballast and bilge water generates from all types of ships (1)(2)(3)(4)(5)(6)(7). Therefore, seas, oceans, coasts, and cities are under risk due to the busy marine transportation.…”

Salinity effect on a biofilm-MBR process for shipboard wastewater treatment

“…In previous studies, both dead-end side-stream and recycle sidestream configurations of a biofilm-MBR have been investigated [7,8]. The recycle side-stream configuration is the preferred process option for integrated shipboard wastewater treatment [8].…”
