Survey and measuring campaign were done to determine flowrates and characteristics of freshwater, wastewater, and treated wastewater stream. Then, water and pollutants mass balances were conducted. As a result, i) important reductions on freshwater consumption (69.5 %) and total water inputs (&gt;66.0 %) in the industrial process can be achieved by implementing direct wastewater reuse; ii) direct wastewater reuse and wastewater recycle can be increased in 12 % and 18 %, respectively, thus contributing in reducing 6.2 % the wastewater generation; iii) batteries' electrolyte is the main source of wastewater pollutants; therefore, it is recommended to rethink and redesign the industrial process to extract batteries’ electrolyte before they are processed; implementing this strategy will contribute in recovering 0.31 m³/1000 batteries/month (248 m³/month) of concentrated sulfuric acid, achieving zero disposal of wastewater, attenuating aquifer pollution by heavy metals and salts, and reducing wastewater treatment costs in 90 %, which represents savings greater than US$ 90,000.00/month or 1.15 million US dollars per year.</div></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":"34 ","pages":"Article 100330"},"PeriodicalIF":7.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145622763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The running water method (RWM) involves continuously running cold water over frozen food and is described as a safe and quicker alternative to thawing in a refrigerator. This thawing method appears to be commonly used in food processing and food service settings, but it has received little attention from food supply chain and/or sustainability researchers. A recirculating faucet device that mimics RWM is available in the U.S. We conducted eight thawing trials with two food types, ground beef (2.27 kg) and a seafood mix (0.91 kg), to compare thawing time and use of water and energy. The thaw methods were: RWM with food placed directly in a sink (unsubmerged), RWM in a container (submerged), a recirculating faucet with submerged food, and a refrigerator. Thawing in a refrigerator took 2-3 days, and the other methods took 74 to 198 minutes. The recirculating faucet used about 9 liters of water for each thaw trial, and RWM used 709 to 1466 liters. Estimated energy use by the recirculating faucet was higher but comparable to refrigerator thawing. In all trials, tap water was warmer than 21°C (the maximum water temperature for RWM in U.S. food safety regulations), but the recirculating water cooled to less than 21°C during thawing with the faucet device.

This review offers an up-to-date information about the structure, reactivity, and stability of e⁻_aq and environmental applications. Various ARPs, particularly generating e⁻_aq such as UV/reductants (sulfite, iodide, dithionite and ferrous ion), and innovative technologies (e-beam, plasma, sonochemistry, photocatalysis) are discussed. Optimal conditions needed to produce enough e⁻_aq, benefits and drawbacks of each system are given in this review. Moreover, the degradation effectiveness of chlorinated and fluorinated chemicals, nitro-derivatives, and other compounds are discussed. It has been found that effectiveness of ARPs, varied with the utilized processes. Per- and polyfluoroalkyl substances (PFAS) were reduced effectively using UV/indole and UV/sulfite processes. UV/iodide needed more time to degrade them. Among the various co-existing interfering matrices, dissolved organic matter was a crucial e⁻_aq scavenger. But, low amounts of humic acids (HA) could boost photo-reductive pollutants degradation. In addition, e⁻_aq -based photochemical methods effectively reduced inorganic compounds i.e., bromates (BrO₃⁻), nitrates (NO₃⁻), arsenic in a form of As(V) and As(III). Types of scavengers as well as methods for identification of reductive species contributing to degradation mechanism were discussed.
