Summary: Waste waters of textile industry have often an amount oftensides, dyestuffs, heavy metals (Fe,Co,Cr,Cu,Zn), which remainafter textile finishing processes. In this project different adsorbents were used for elimination ofimpurities from waste waters of textile industry. Natural aluminosilicates with a high amount of amorphous silica,kaoline, zeolite, activated carbon in a process of adsorption andione exchange of heavy metals, dyestuffs and tensides from watersolutions were investigated. The influence of adsorbent weight and granulation, concentrationof solutions, pH values and temperature were investigated. The results were followed by physical-chemical methods:spectrophotometry, electrical conductivity, surface tension andlight radiation reflectance determination (DATACOLOR), and bymeans of computer calculation.

Keywords: Waste waters of textile industry, adsorption and ione exchange, aluminosilicates, dyestuffs, tensides, heavy metals

Research goals: Discovery and application of the systems and methods which in ashort time could remove different inorganic and organicimpurities from textile industry waste waters. Decreasing of water impurities and using regenerated water intextile finishing processes. Discovery of optimum conditions for elimination of impuritiesfrom textile industry waste waters. Using domestic natural and synthetic substances for waste watertreatment and savings of matter and energy.
