Topic Information

Dear Colleagues,

Drought, population growth, energy and land use, socioeconomic changes, and a shifting climate exacerbate the pressure on water and energy infrastructures. Therefore, it is critical to re-think how water and electricity are managed, including their interactions, e.g., water used to generate energy, and energy used in water treatment.

By focusing on the nexus between water and energy, we aim to identify sustainable strategies and technologies that can alleviate the mounting pressures on these vital resources. However, we also recognize the importance of examining water and energy individually to gain a comprehensive understanding of their unique complexities.

In this sense, this topic aims to provide a platform for researchers and participants from academic and industrial sectors to report their recent research findings that contribute to the comprehensive understanding and effective planning and management of water and energy systems. To this end, five journals were meticulously selected: Water, Energies, Sensors, Sustainability, and Data.

We are pleased to invite the research community to submit review or regular research papers focusing on, but not limited to, the following relevant topics related to water and energy monitoring and their nexus:

  • Water and energy monitoring technologies;
  • Electricity and water disaggregation;
  • Water–energy and energy–water nexus modelling;
  • Water–energy–food nexus modelling;
  • Public datasets;
  • Standards for data sharing and re-use;
  • Decision-making tools;
  • User experience and visualization of the water–energy and energy–water nexus;
  • Human factors in water–energy and energy–water nexus;
  • Water–energy and energy–water nexus integration in buildings and industries;
  • Optimization considering the water–energy and energy–water nexus;
  • Integration of RES and DER in energy and water infrastructures and their nexus;
  • Forecasting of power production and demand in water–energy and energy–water nexus;
  • Forecasting water demand in water–energy and energy–water nexus.

Treatment wetlands (TWs) are Nature-Based Solutions which have been increasingly used worldwide for wastewater (WW) treatment as they are able to remove mineral and organic pollutants through both physical and biochemical processes. Besides the reusable effluent, the TWs produce, as their main output, plant biomass that needs to be harvested and disposed of at least once a year with significant management costs and causing the TW to be temporarily out of service. This study aims (i) to evaluate the potential of TWs’ biomass for local energy production and (ii) to understand the effects of TWs’ hydraulic conductivity (Ks) on the biomass biomethane yield. Specifically, this was addressed by determining the Biochemical Methane Potential of common reed (CR) (Phragmites australis) samples collected at three harvest times from the 10-year-old horizontal subsurface treatment wetland (HSTW) used as a secondary WW treatment system for the IKEA® store situated in Catania (Eastern Sicily, Italy). Furthermore, the falling-head test was conducted to assess the hydraulic conductivity (Ks) variation in the hydraulic conductivity (Ks) of the HSTW, in order to understand its influence on the CR biomethane production. The average methane content values were 130.57 Nm3CH4/tVS (±24.29), 212.70 Nm3CH4/tVS (±50.62) and 72.83 Nm3CH4/tVS (±23.19) in August, September, October 2022, respectively. Ks was correlated with both dry matter (R2 = 0.58) and fiber content (R2 = 0.74) and, consequently, affected the biomethane yield, which increased as the Ks increased (R2 = 0.30 in August; R2 = 0.57 in September). In the framework of a circular economy, the results showed the successful possibility of integrating bioenergy production into TWs. The research could contribute (i) to encouraging plant operators to reuse biomass from TWs for local energy production and (ii) to help plant operators to understand Ks effects on the biomass biomethane yield in order to increase the sustainability of the system and to reduce the maintenance costs.

To enhance the nutrient removal efficiency of Oocystis borgei for mariculture wastewater (MW), the effects and processes of three phytohormones on nitrogen and phosphorus removal from synthetic mariculture wastewater (SMW) by O. borgei under sequential batch operation were compared. The findings revealed that the supplementation with 10−6 M 3-indoleacetic acid (IAA), gibberellic acid (GA3), and zeatin (ZT) resulted in the most effective elimination, while there was no appreciable difference among them. The nitrogen and phosphorus indices of the effluent dramatically reduced (p < 0.01) upon the supplementation of phytohormones, and the removal effects were ranked as NO3−-N > PO43−-P > NH4+-N > NO2−-N. The removal rates for NH4+-N and PO43−-P were 0.72–0.74 mg·L−1·d−1 and 1.26–1.30 mg·L−1·d−1, respectively. According to physiological studies, phytohormones enhanced the levels of photosynthetic pigments and chlorophyll fluorescence parameters (Fv/Fm and φPSII), thereby improving photosynthetic activity. Additionally, they stimulated Nitrate Reductase (NR) and Glutamine Synthetase (GS) activities to promote nitrogen metabolism and increased Superoxide Dismutase (SOD), Catalase (CAT), and carotenoid contents to mitigate oxidative stress damage caused by abiotic stress. These activities contribute to the proliferation of O. borgei, which in turn resulted in an increase in the assimilation of nitrogen and phosphorus from SMW. In conclusion, phytohormone supplementation significantly increased nutrient removal from SMW by O. borgei in a sequential batch reactor, which has potential application in MW treatment. Full article
