life cascade

Start date: 1st October 2023  – Duration: 48 months

The CASCADE  project is aimed at evaluating at a laboratory scale and testing at a demonstrative scale a series of treatment technologies to remove PFAS and Microplastics from wastewater both at the level of textile companies and at the level of centralized wastewater treatment plants.

The goal of the project will be the identification of the best and most feasible combination to be implemented in a textile district.

The implementation of the treatments will make it possible to reduce the discharge into the environment of these micropollutants both with the treated wastewater and with the sewage sludge and will allow reuse of the treated wastewater avoiding the reintroduction of pollutants into the production system.

The project also foresees to deepen the ecotoxicological assessment and to develop the feasibility of feeding the industrial aqueduct with treated wastewater.

PFAS: perfluorinated alkylated substances.  They are the most persistent emerging micropollutants. The widespread use of PFAS  together with their high persistence have led to the ubiquitous occurrence of this group of chemicals in the environment. PFAS have been used for a wide range of functional applications within textiles, upholstery, leather apparel, and carpets: fluorochemicals are the most commonly used repellents in the textile industry.
Microplastics: solid particles with dimensions ranging from 1 to 1000 𝜇m (micrometer), with “large microplastics” reaching sizes of up to 5 millimeters. Microplastics have been found in various environments, including freshwater, marine ecosystems, drinking water, and wastewater. Plastic materials in urban and industrial wastewater comprise pipe fragments, personal hygiene products, materials from tire wear, and textile fibers released during washing and industrial processes.
