Abstract

Sintetska su vlakna u velikoj mjeri zamijenila tradicionalna, prirodna vlakna te dominiraju u modnoj i tekstilnoj industriji. Međutim, prilikom proizvodnje i primjene sintetskih vlakana velika je vjerojatnost za formiranje i otpuštanja tzv. mikrovlakana u okoliš i za onečišćenje okoliša. Jedan od najčešćih unosa mikrovlakana u morski i vodeni okoliš je putem otpadne vode iz procesa pranja i njege sintetskih tekstilnih materijala. U ovome radu određeni su parametri kemijske i biokemijske potrošnje kisika u efluentima nakon pranja PES tkanina standardnim postupkom te je procijenjen utjecaj obrade PES tkanina kitozanom na kemijske karakteristile efluenata od pranja, prije i nakon provedenog postupka membranske filtracije. Karakterizacija efluenta je provedena određivanjem kemijske potrošnje kisika (KPK) prema HRN ISO 15705:2005, biokemijske potrošnje kisika (BPK5) OxyTop-om te suspendiranih tvari prema HRN EN 872:2008.

Abstract (english)

Synthetic fibres have largely replaced traditional, natural fibres and they dominate fashion and textile industry. However, during the production i application of synthetic fibres, there is a high probability of formation and release of so-called microfibres into the environment and for the environmental pollution. One of the most common inputs of microfibres into the marine and aquatic environment is through wastewater from the washing process and care of synthetic textile materials. In this paper, the parameters of chemical and biochemical oxygen consumption in effluents after washing PES fabric by standard procedure were determinated and the influence of treatment of PES fabric with chitosan on chemical characteristics of washing effluents, before and after membrane filtration procedure was applied. Characterization of the effluent was performed by determinating the chemical oxygen demand (COD) according to HRN ISO 15705:2005, biochemical oxygen demand (BOD5) by OxyTop and suspended solids according to HRN EN 872:2008.
