“…Indeed, the oil droplets on the membrane surface can coalesce and form a continuous layer on the surface. Oil can also form a liquid lining inside the pores, reducing the effective pore radius . Table shows the average permeate quality and corresponding rejection rates in terms of turbidity, TOC, and hydrocarbon (HC) content.…”

Bio‐refractory wastewater treatment is compulsory for a safe discharge into the environment. This paper aims to study the use of membrane processes to concentrate wastewater to be then treated by a hydrothermal process such as wet air oxidation for advanced and intensified wastewater treatment. The work focused on three different synthetic wastewaters of public or industrial interest: pharmaceutical wastewater, grey wastewater, and bilge wastewater. Membrane processes operated at the pilot scale enabled retentions as high as 100% of total organic carbon, more than 99% of turbidity, and 70% of hydrocarbon, respectively. High concentration factors were obtained. Membrane foulings were chemically reversible whatever the type of wastewater or the membrane process. Thanks to membrane filtrations, the volumes to be treated by wet air oxidation were drastically reduced, leading to high energy savings. Membrane retentates were then treated by wet air oxidation (300°C, 15 MPa) and resulted in more than an 83% mineralization rate, regardless of the effluent. The hybrid intensified process presented in this work strongly increased the possibility of discharging into the environment by mixing the process outputs or greatly reducing the discharge volume and ultimately the waste load.

“…Over 40 % of produced water is believed to be discharged into the environment 3) , so the discharge of produced water into the environment is a global issue. To reduce the levels of contaminants to satisfy national environmental regulations and to recycle produced water, various treatment technologies, including conventional methods such as hydrocyclones, membranes, adsorbents, and separation by floating or precipitation, have been adopted for the treatment of produced water 4), 5) . Some technologies have been combined according to the composition of the produced water.…”

A novel treatment technique for produced water was developed using organic nanotubes (ONTs) as adsorbents. ONTs formed by the self-assembly of peptide lipids are known to adsorb heavy metals and hydrophobic molecules. Preferential adsorption of heavy metals against alkali-and alkali-earth metals above pH 6 was confirmed. Pb 2 in high-salinity model produced water was reduced to 0.04 ppm by treatment with ONTs, compared to 0.84 ppm without ONTs. The selectivity of Pb 2 against alkali-earth metals was over 3000. Design of the molecular structures of peptide lipids reduced the content of p-cresol in model produced water from 13 to less than 1 ppm. To improve separation from wastewater, ONTs hybridized with magnetic nanoparticles (MNPs) were obtained through the pH adjusting method. Hybrids maintained the hybridized state over a wide pH range (1-9). Adsorption tests using real produced water indicated that ONTs could adsorb heavy metals, suspended solids, oil, and some organic compounds in produced water in a one-step process, without pre-treatment.

“…This results in a mixture of saline water and hydrocarbons, named "produced water" [1] whose discharge could be of great environmental impact. Basically, Dickhout et al (2017) [2] in a recent review, define produced water as an oil-in-water emulsion, where the oily phase is dispersed in the aqueous phase, stabilized by surfactants. The composition of product water is highly variable with the oil field ages.…”

“…Even though several studies have been carried out about produced water treatment [1,2,[8][9][10][11][12][13][14][15][16][17], shipboard slops wastewater treatment is a topic worthy of further investigation also in light of the lack of information and research articles regarding their treatment [5][6][7]. Among the difficulties relating to the treatment of such wastewater, the characterization is a first obstacle related to the proper nature of wastewater, rich in floating oils and emulsified phases [5], which hinds the repeatability and the reproducibility of analytical methods.…”

“…Fouling of membranes is the first drawback of MBRs and it is the deposition of substances on the membrane surface, like oil droplets or solid particles. Dickhout et al (2017) [2] proposed a fouling mechanism for oily wastewater and they found that oil droplets are coalescing on the membrane surface, forming a continuous oil layer on the surface, different from a traditional cake layer made of separate particles. In this context, membrane materials are relevant for the treatment of oily wastewater and, until now, ceramic membranes are favored over polymeric membranes because of their superior mechanical stability.…”

Shipboard slop wastewaters are produced by the activity of washing of oil tankers with seawater, and are characterized by high salinity and hydrocarbons. In this context, harbor authorities are forced to respect the international regulation IMO-MARPOL 73/78 and they must treat slop wastewater before discharging to the sea. This study compared data from three stand-alone treatments working with the same real slop wastewater: (1) a chemical treatment of coagulation-flocculation with aluminum sulphate as coagulant and an anionic flocculant (A57), (2) a physical treatment of adsorption on granular activated carbon (GAC), (3) two biological treatments represented by a membrane bioreactor (MBR) and a moving bed biofilm reactor (MB-MBR). GAC treatment registered the highest removal efficiency of total petroleum hydrocarbons (ηTPH) next to 85%, since the activated carbon had excellent adsorption properties towards organic substances. The coagulation-flocculation treatment reported the lowest ηTPH ≈ 57% due to the presence of emulsified hydrocarbons that were not affected by the coagulant and flocculant action, so remaining in liquid phase. ηTPH ≈ 70% obtained with MB-MBR fed with 100% volume of slop, suggested biomass acclimation to salinity and hydrocarbons. Based on the results of each process, three main treatment chains are proposed depending on the hydrocarbons load of the real slop wastewater.
