“…Likewise, Cartagena et al [17] obtained high removal rates (>99%) of various classes of micropollutants in the permeates from NF and RO membranes. Corroborating these two studies, Rodriguez-Mozaz et al [29] attained concentrations below 16 ng•L −1 in a combined system of UF and RO membranes. According to the authors, the use of a MSP to remove micropollutants can be strongly recommended, because unlike AOPs, there is no formation of byproducts and the process also serves as a barrier to possible microorganisms coming from the previous biological system.…”

Micropollutants are defined as contaminants found in trace concentrations in water bodies that are persistent and bioactive, meaning they are not completely biodegradable and cannot be removed by conventional water treatment methods. Because of these aspects, their detection and removal pose a challenge to the scientific community. Among them are endocrine disruptors, drugs, agricultural chemicals, personal grooming products, industrial additives and others. These micropollutants are the cause for global concern, because their presence in water supply systems is suspected of causing health problems in humans and animals. To develop efficient techniques to remove them, it is fundamental to understand their physico-chemical properties and the available treatment types and conditions. Membrane separation processes (MSPs) and advanced oxidation processes (AOPs) are the focus of this literature review, as potential treatment methods to remove micropollutants. The former process stands out for high rejection rates (above 90%) of various micropollutants, but it generates a concentrated secondary waste stream. In turn, the latter process can remove micropollutants without generating secondary wastes, and can also be applied and combined with other treatment methods.

“…Along with the purification of wastewater, the RO process produces a concentrate containing high levels of rejected pollutants (about 15-20% of the influent volume) [4]. Some of the emerging pollutants, such as pharmaceuticals and personal care products, are very persistent in sewage effluent, resulting in raised awareness of the environmental risk of RO concentrates [1,5,6]. Genotoxicity evaluation using the SOS/umu test has provided direct evidence that RO concentrates have much higher toxicological risk than RO influents [7].…”

Removal of Crotamiton from Reverse Osmosis Concentrate by a TiO2/Zeolite Composite Sheet

et al. 2017

Abstract:Reverse osmosis (RO) concentrate from wastewater reuse facilities contains concentrated emerging pollutants, such as pharmaceuticals. In this research, a paper-like composite sheet consisting of titanium dioxide (TiO 2 ) and zeolite was synthesized, and removal of the antipruritic agent crotamiton from RO concentrate was studied using the TiO 2 /zeolite composite sheet. The RO concentrate was obtained from a pilot-scale municipal secondary effluent reclamation plant. Effective immobilization of the two powders in the sheet made it easy to handle and to separate the photocatalyst and adsorbent from purified water. The TiO 2 /zeolite composite sheet showed excellent performance for crotamiton adsorption without obvious inhibition by other components in the RO concentrate. With ultraviolet irradiation, crotamiton was simultaneously removed through adsorption and photocatalysis. The photocatalytic decomposition of crotamiton in the RO concentrate was significantly inhibited by the water matrix at high initial crotamiton concentrations, whereas rapid decomposition was achieved at low initial crotamiton concentrations. The major degradation intermediates were also adsorbed by the composite sheet. This result provides a promising method of mitigating secondary pollution caused by the harmful intermediates produced during advanced oxidation processes. The cyclic use of the HSZ-385/P25 composite sheet indicated the feasibility of continuously removing crotamiton from RO concentrate.

“…Therefore, improving farmer knowledge about utilizing pesticides for each product, application dosage, and utilization frequency to reduce the risk of pesticide intake by society is highly recommended [21]. On the other hand, consecutive and precise supervision by experienced experts on toxin utilization and pesticide types is essential [22].…”

Pesticides along with with their degradation products spread throughout the environment and contaminate the water, leading to a consequent potential risk to humans and also the environment. The study aims to determinene the residual pesticides (organophosphorus, pyrethroids ), herbicides, and fungicides in the water resources (wells, deep wells, springs, spring-heads, and flumes) of Kermanshah Province, Iran. Water samples were taken from 50 stations from April to June 2016, and analyses were performed using gas-chromatography-mass-spectrometry techniques. Data were analysed using SPSS version 20. One of the most important points of this study is the fact that all water resources were safe except for deep wells. Total concentration of organophosphorus was 2.2 ppb. The mean concentration of pyrethroids in Islamabad Gharb and Songhor was 0.574 and 2.235 ppb, respectively. Organophosphorus and pyrethroid pesticides total concentration was more than the European standard. The contamination range of difenoconazole fungicide was 0.024 ppb (Gilan Gharb) and 1.089 ppb (Kermanshah). Glyphosate herbicide was only seen in Islamabad Gharb (0.011 ppb). The mean concentration of all pesticides in the investigated wells was more than the European standard. Estimating pesticide concentration is important for preserving aquatic ecosystems and human health.
