Ecotoxicity of AOP treated waters was measured using Aliivibrio fischeri (A. fischeri) bioluminescence inhibition tests, and this work demonstrates important considerations for applying A. fischeri tests during AOP treatment. Nine high strength aqueous waste streams were investigated to represent a range of background matrix characteristics that may be found in wastewaters. Propanil was used as a model contaminant to systematically study the effects of these matrix factors on bioluminescence inhibition during AOP treatment. Because overlapping and sometimes conflicting matrix effects can limit the insight A. fischeri tests provide about the impact of treatment, experimental results were combined with literature to develop an A. fischeri Visual Guide (AFVG) to support operators and/or system remediators in interpretation of A. fischeri results. The AFVG is a novel decision support tool which facilitates timely, effective remediation while maintaining wastewater treatment system operations and minimizing impacts to downstream receiving waters.","PeriodicalId":51583,"journal":{"name":"Environmental Processes-An International Journal","volume":"13 3","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13679716/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149229283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to concentrate and solidify leachate from an effluent treatment plant processing approximately 8750 m3 annually, achieving resource recovery and environmental compliance. A 300 L h-1 cooling demonstration plant was designed and implemented, incorporating a chiller, a secondary refrigerant mixture (40% ethylene glycol and 60% water), a clarifier, a reactor, and pumps. Μodelling with OLI software estimated recovery rates for salt and ice, providing a basis for operational adjustments. Leachate samples (2000 L) and concentrate (1000 L) were processed to evaluate the plant's performance in recovering clean water and Na2SO4. Experimental results confirmed the model predictions, with 302 L of concentrate yielding 102.9 kg of Na2SO4 over 6 h and 273 L of leachate producing 118.7 kg of high-purity ice over 5.5 h. The energy consumption was measured at 171 kWh t-1 of ice, aligning with theoretical predictions for a coefficient of performance of 1. These results validate the efficiency and feasibility of PFC in resource recovery. This study highlights the importance of PFC as a low-cost, energy-efficient technology for hazardous leachate treatment. Its scalability and ability to recover valuable resources such as Na2SO4 and clean water present a sustainable alternative to conventional methods, contributing to zero-waste management goals in waste treatment practices.Supplementary information: The online version contains supplementary material available at 10.1007/s40710-025-00757-3.","PeriodicalId":51583,"journal":{"name":"Environmental Processes-An International Journal","volume":"12 2","pages":"15"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11956536/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
