“…Sustainable wastewater treatment systems should be designed to maximize energy and resource (nutrient and water) recovery. 2 Water is the major and the most valuable resource that can be recovered from these operations. While current aerobic processes for carbon and nitrogen removal are energy-intensive, 3 energy recovery in wastewater treatment can be achieved by concentrating and converting organic compounds to CH 4 in an anaerobic digester.…”

Transitioning Wastewater Treatment Plants toward Circular Economy and Energy Sustainability

Aging infrastructure, increasing environmental regulations, and receiving water environment issues stem the need for advanced wastewater treatment processes across the world. Advanced wastewater treatment systems treat wastewater beyond organic carbon removal and aim to remove nutrients and recover valuable products. While the removal of major nutrients (carbon, nitrogen, and phosphorus) is essential for environmental protection, this can only be achieved through energy-, chemical-, and cost-intensive processes in the industry today, which is an unsustainable trend, considering the global population growth and rapid urbanization. Two major routes for developing more sustainable and circular-economy-based wastewater treatment systems would be to (a) innovate and integrate energy- and resource-efficient anaerobic wastewater treatment systems and (b) enhance carbon capture to be diverted to energy recovery schemes. This Mini-Review provides a critical evaluation and perspective of two potential process routes that enable this transition. These process routes include a bioelectrochemical energy recovery scheme and codigestion of organic sludge for biogas generation in anaerobic digesters. From the analysis, it is imperative that integrating both concepts may even result in more energy- and resource-efficient wastewater treatment systems.

“…The main routes for pharmaceuticals entering the environment are wastewater streams due to their release into surface waters or through ground systems, when the treated wastewater is used for irrigation or when sewage sludge is applied as a fertilizer to improve soil properties on agricultural land [1]. Many reports show that conventional wastewater treatment plants that have been designed and optimized to remove suspensions and compounds responsible for eutrophication (e.g., biodegradable organic matter, nitrogen, and phosphorus) are not sufficient to remove many pharmaceuticals [1][2][3][4][5].…”

“…Additionally, in the case of TRC, ozonation and AOPs ensure complete transformation of this molecule into intermediate products [5,21,22]. Although the AOPs allow complete degradation of TRC, they do not provide complete mineralization of oxidation products (OPs) [5,23,24]. In the case of antibiotics, total mineralization is very difficult, because the arrangement of aromatic rings in their structure tends to stabilize the oxidation by-products formed during photolysis [25].…”

The possibility of removing tetracycline (TRC) from water in an integrated advanced oxidation and membrane filtration process was investigated. Ozonation and UV/H2O2 photooxidation were applied for the destruction of TRC. Six oxidation products (OPs) retaining the structural core of TRC have been identified. One new TRC oxidation product, not reported so far in the literature, was identified—ethyl 4-ethoxybenzoate. All identified OPs were effectively retained on the membrane in the nanofiltration process. However, chemical oxygen demand (COD) measurements of the filtrates showed that in the case of UV/H2O2 oxidation, the OPs passed through the membrane into the filtrate. Various water matrices were used in the research, including the river water untreated and after ozone treatment. It has been shown that organic matter present in surface water can improve pharmaceutical retention, although it contributes to significant membrane fouling. Pre-ozonation of the river water reduced the membrane fouling. The XPS analysis was used to show ozone and H2O2 influence on the top polymer layer of the membrane. It was shown that the oxidants can damage the amide bond of the polyamide.

“…e annual production and consumption of TC can reach thousands of tons worldwide. e TC used in the agricultural industry is excreted through faeces and urine as unmodified parent compounds, with only a small portion being metabolized [5][6][7]. In recent years, residual TC, including that discharged from pharmaceutical factories and agricultural runoff, has been frequently detected in surface water, groundwater, and even drinking water [8,9].…”

The pharmaceutical wastewater (PW) produced during the production of antibiotics has a huge impact on the ecological environment. The efficient removal of residual antibiotics from PW has become a great challenge. Here, a ZIF-8/GO composite film, a new material, was prepared by loading ZIF-8/GO nanosheets onto the surface of a polyethyleneimine- (PEI-) modified nylon microporous support. This new material can effectively remove tetracycline (TC) from PW with a removal rate of 99%. In addition, the layer of ZIF-8/GO nanosheets on the surface of the carrier had certain defect sites. This feature not only made the film have a relatively high flux (502 L·m−2·h−1·bar−1) but also overcame the disadvantages of the traditional membrane separation technology, such as the high operation pressure required by the easy plugging of micropores. More importantly, the abovementioned advantages enable the novel material to be applied on a larger scale. A probable adsorption mechanism was investigated and suggested.
