Biougljen - održivi materijal za uklanjanje zagađivala iz otpadnih voda tekstilne industrije

Prisutnost zagađivala u otpadnim vodama predstavlja okolišni problem, između ostalog i zbog nastajanja opasnih nusprodukata. Smjernice održivog razvoja zahtijevaju razvoj novih tehnologija za smanjenje potrošnje vode, kao i smanjenje negativnog utjecaja ispuštenih otpadnih voda na okoliš. Navedeni zahtjevi odnose se na sve industrijske grane s naglaskom na tekstilnu industriju koje je jedna od vodećih industrijskih grana po količinama i stupnju onečišćenja otpadnih voda. Zato je potrebno razvijati nove i održive tehnologije kojima će s smanjiti koncentracija štetnih tvari u otpadnim vodama. U ovome radu dat će se pregled svojstava biougljena, izvora iz kojih se dobiva, metoda njegove karakterizacije te mogućnosti primjene biougljena u zaštiti okoliša s naglaskom na održivo pročišćavanje otpadnih voda tekstilne industrije.The presence of pollutants in wastewater is an environmental problem, among other things due to the formation of hazardous by-products. Guidelines for sustainable development require the development of new technologies to reduce water consumption, as well as reduce the negative impact of wastewater on the environment. These requirements apply to all industries with emphasis on the textile industry, which is one of the leading industries . Therefore, it is necessary to develop new and sustainable technologies that will reduce the concentration of harmful substances in wastewater. This paper will provide an overview of the properties of biochar, sources from which it is obtained, the method of its characterization and the possibility of using biochar in environmental protection with emphasis on sustainable treatment wastewater of the textile industry

Karakterizacija efluenata i filtarskog kolača nakon pranja poliesterskih tekstilija

Mikroplastika je postala brzorastući onečišćivač koji, zbog svoje prisutnosti u okolišu i čovjekovom neposrednom okruženju privlači pažnju znanstvenika u otkrivanju štetnih utjecaja na ljudsko zdravlje i okoliš. Tekstilni materijali prepoznati su kao potencijalno važan izvor čestica mikroplastike. Oni u velikim količinama dospijevaju u vodene ekosustave tokom proizvodnje i uporabe, a pojnaviše iz procesa pranja sintetskih tekstilnih materijala. U ovom radu praćeno je otpuštanje čestica mikrovlakana u procesu pranja PES/pamuk tkanine tokom 10 ciklusa pranja s naglaskom na usporedbu dviju različitih tehnologija pranja: standardni i inovativni postupak pranja. Procjena količine otpuštenih čestica u efluentima ispitana je određivanjem standardnih fizikalno-kemijskih parametara u ispitivanju kvalitete otpadnih voda (pH vrijednost, elektrovodljivost, mutnoća, ukupna čvrsta tvar, ukupna suspendirana tvar i ukupna otopljena tvar te KPK vrijednost). Naposlijetku je provedena mikroskopska karakterizacija čestica zaostalih na filtarskom kolaču.Microplastics have become a fast-growing pollutant, which, due to its presence in the environment and the human immediate environment, attracts the attention of scientists in the detection of harmful effects on human health and the environment. Textile materials are recognized as a potentially important source of microplastic particles. They reach aquatic ecosystems in large quantities during production and use, mostly from the washing process of synthetic textile materials. In this work, the release of microfiber particles in the washing process of PES/cotton fabric was monitored during 10 washing cycles with an emphasis on the comparison of two different washing technologies: standard and innovative washing process. The estimation of the amount of released particles in the effluents was tested by determining standard physico-chemical parameters in waste water quality testing (pH value, electrical conductivity, turbidity, total solid matter, total suspended matter and total dissolved matter and COD value). Finally, a microscopic characterization of the particles remaining on the filter cake was carried out
