The influence of temperature on impurities removal from waste waters after raw wool scouring

Sažetak
Water is used very often in the textile industry because the most technical processes work in water medium. Therefore high amounts of waste waters appear and they give higher or lower impurities to environmental. The most impurities of waste waters appear after raw wool scouring and waters have different inorganic and organic substances depending on their origin. Wool is most often scoured by using of tensides and today by using of enzymes on higher temperatures (40-45o C). Waste waters flow out from the processes with the temperature of about 35o C and they could be so used in heating exchangers and then colder drop into natural water streams. Before recycling they must be purified because waste waters could make problems and harms on engines in driving. Therefore the best treatment for purifying of waste waters is a process of impurities adsorption on suitable adsorbents because the biological treatment requires a big area and much time for the activity and it is not suitable for using on higher temperatures. Therefore in these investigations a process of the impurity adsorption on natural and synthetic aluminosilicates on two different temperatures ( 25oC and 35oC) has been used. The results were compared with these, which have been done with actived carbon. The results of these investigations were followed by electrical conductivity, surface tension, chemical analysis and pH measurements of filtrates during the isothermal process of the adsorption.
