In the production of lindane, significant quantities of other HCH isomers are generated as byproducts. All these compounds are typically stored in landfills, often with poor management practices. Polyamide membranes, two commercial membranes from Alfa Laval (NF99HF and NF99) and homemade thin film composite membranes prepared by interfacial polymerization on a porous polyimide support, were evaluated for water nanofiltration (NF) of HCH isomers, including lindane. Homemade membranes, with a lindane rejection of 91.3 % and a permeance of 2.7 L·m−2·h−1·bar−1, offered the highest performance in terms of both permeance and rejection. NF99 and homemade membranes were proven to be equally effective in removing α-HCH and β-HCH, showing similar results. Homemade membranes achieved 99.5 and 99.8 % rejections for α-HCH and β-HCH, respectively. Long-term experiments were carried out with NF99 and homemade membranes to assess their stability during filtrations with lindane solutions for up to 214 h. Homemade TFC membrane maintained its initial rejection (ca. 93.5 %) after 214 h, although its permeance decreased over time, ending in 2.5 L·m−2·h−1·bar−1. info:eu-repo/grantAgreement/ES/DGA-FSE/T43-20R info:eu-repo/grantAgreement/ES/DGA/T68-23R info:eu-repo/grantAgreement/ES/FJC-2021-047822-I info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 6.7 2024 ENGINEERING, CHEMICAL 28 / 176 = 0.159 2024 Q1 T1 WATER RESOURCES 9 / 132 = 0.068 2024 Q1 T1 ENGINEERING, ENVIRONMENTAL 21 / 83 = 0.253 2024 Q2 T1 1.348 2024 Biotechnology 2024 Q1 Process Chemistry and Technology 2024 Q1 Water Science and Technology 2024 Q1 Waste Management and Disposal 2024 Q1 Safety, Risk, Reliability and Quality 2024 Q1 9.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lasobras, Javier Universidad de Zaragoza (orcid)0000-0002-7488-6196 Coronas, Joaquín Universidad de Zaragoza (orcid)0000-0003-1512-4500 Menéndez, Miguel Universidad de Zaragoza (orcid)0000-0002-2494-102X Luque-Alled, José Miguel Universidad de Zaragoza (orcid)0000-0001-5002-7197 5005 555 Universidad de Zaragoza Dpto.
