“…The use of PMRs shortened the process route for catalyst recovery, reduced the size of installation, and also enabled the continuous production with low energy consumption (Mozia, 2010). In this regard, PMRs were considered to be a promising technology in natural organic matter (Choo et al, 2008), pharmaceuticals and endocrine disrupting compounds removal (Benotti et al, 2009), municipal wastewater (Mozia et al, 2014), and dye wastewater treatment (Mozia et al, , 2009.

h i g h l i g h t s g r a p h i c a l a b s t r a c tFor the first time, homogeneous catalytic ozonation and membrane distillation were coupled in a membrane reactor. Organics and salts were efficiently removed and the homogenous catalyst was almost 100% recovered simultaneously. Membrane fouling was effectively mitigated compared to MD process.a r t i c l e i n f o b s t r a c tA novel catalytic ozonation membrane reactor (COMR) coupling homogeneous catalytic ozonation and direct contact membrane distillation (DCMD) was developed for refractory saline organic pollutant treatment from wastewater. An ozonation process took place in the reactor to degrade organic pollutants, whilst the DCMD process was used to recover ionic catalysts and produce clean water. It was found that 98.6% total organic carbon (TOC) and almost 100% salt were removed and almost 100% metal ion catalyst was recovered. TOC in the permeate water was less than 16 mg/L after 5 h operation, which was considered satisfactory as the TOC in the potassium hydrogen phthalate (KHP) feed water was as high as 1000 mg/L. Meanwhile, the membrane distillation flux in the COMR process was 49.8% higher than that in DCMD process alone after 60 h operation. Further, scanning electron microscope images showed less amount and smaller size of contaminants on the membrane surface, which indicated the mitigation of membrane fouling. The tensile strength and FT-IR spectra tests did not reveal obvious changes for the polyvinylidene fluoride membrane after 60 h operation, which indicated the good durability. This novel COMR hybrid process exhibited promising application prospects for saline organic wastewater treatment.

“…Owing to that fact, we concluded that primary effluents should not be directly treated in the PMR but a pretreatment of the wastewater is necessary. A detailed discussion on the permeate flux and membrane fouling during treatment of PE and SE in the PMR can be found in earlier work …”

BACKGROUND: The pollution of the aquatic environment by pharmaceuticals has become a serious problem. Conventional technologies applied in water or sewage treatment plants are not effective in drugs removal, therefore there is an urgent need to develop new methods. RESULTS:The removal of diclofenac (DCF), ibuprofen (IBU) and naproxen (NAP) sodium salts in a photocatalytic membrane reactor (PMR) utilizing direct contact membrane distillation and UV-C radiation from ultrapure water, tap water, primary effluents (PE) and secondary effluents (SE) of municipal wastewater treatment plant is presented. When PE were used as feed and TiO 2 loading of 0.5 g dm −3 was applied, DCF was removed completely, IBU amount decreased for 73% and NAP for 90%. In the case of SE, DCF, IBU and NAP concentrations decreased by 100%, 93% and 94%, respectively (1.5 gTiO 2 dm −3 ). Mineralization was low and did not exceed 14% for PE and 23% for SE. No drugs were found in the distillate, however, it contained high level of N-NH 4 + , especially in PE.CONCLUSION: The hybrid system can be an effective technology for the removal of pharmaceuticals from SE and PE, however, owing to membrane fouling the latter should be pretreated before application in the PMR.

“…The PMRs utilizing pressure driven membrane techniques have been applied for removal of different organic compounds, such as natural organic matter (NOM) [46,[151][152][153], pharmaceuticals [50,[154][155][156][157], dyes [158][159][160], phenanthrene [33], and viruses [25] or Cr(VI) [161]. Moreover, application of PMRs for treatment of textile and wood processing industry wastewater [162,163], primary and secondary effluents from municipal wastewater treatment plants [26,148,[164][165][166], and surface waters [167] has been reported.…”

This paper presents an overview of recent reports on photocatalytic membrane reactors (PMRs) in organic synthesis as well as water and wastewater treatment. A brief introduction to slurry PMRs and the systems equipped with photocatalytic membranes (PMs) is given. The methods of PM production are also presented. Moreover, the process parameters affecting the performance of PMRs are characterized. The applications of PMRs in organic synthesis are discussed, including photocatalytic conversion of CO2, synthesis of KA oil by photocatalytic oxidation, conversion of acetophenone to phenylethanol, synthesis of vanillin and phenol, as well as hydrogen production. Furthermore, the configurations and applications of PMRs for removal of organic contaminants from model solutions, natural water and municipal or industrial wastewater are described. It was concluded that PMRs represent a promising green technology; however, before the application in industry, additional studies are still required. These should be aimed at improvement of process efficiency, mainly by development and application of visible light active photocatalysts and novel membranes resistant to the harsh conditions prevailing in these systems.
