Lectures : 1. The global problems of environment The global warming, the distorting of ozone layer, the acidic atmospheric deposition, the endangering of biological diversity, the soil degradation, the water contamination, the progress of human population, the growth in consumption of resources. 2. General ecology. The bases of toxicology Principal concepts of ecology. Principal components of ecosystems, its interactions at proceed processes in ecosystems. The environment of human, its components and linkages beetwen them. The types of environment. The sources of biosphere. Poisons, comustibles, explosines. The detection of toxic properties of materials. Inorganic and organic harmful materials and their effects. The classification of dangerous materials. Safety data sheets. Safety R and S phrases. 3. The evaluation of environment condition. Waste management Air pollution, materials contamined air. The effect of industry to the environment. Textile industry and the environment. Noise problems. Waste management, waste distribution, waste disposal. 4. The water in textile industry The water quality and its evaluation. The requirements for water quality in textile industry. The water treatment for potable and plant purposes (rough - prepurification, coagulate reactions, separation, desinfection). The purification of waste water in textile industry. The evaluation of waste water. Mechanical treatment. Chemical treatment (neutralization, chemical coagulation). Biological treatment (filters, activation). Third level of the purification (ultrafiltration, reversal osmosis). The treatment of the sludges from waste water treatment plant. 5. Detergents and the environment. Ecological aspects of textile printing The components of detergents and their effects (surfactants, complexing agents, bleaching agents, antiredepositional substances, the enzymes, foam controllers, antimicrobial substances, compositions of the perfume). The effects of the detergents to environment. Biological degradation of the detergents. Biological tests of the degradations. The law about detergents. The products to use for textile printing and their selection from environment protection aspect. The decrease possibilies of the contamination by reactive dyestuffs printing (dyestuffs, ingredients). The requirements of clients for the textile printing from ecological aspect. 6. Ecological aspects of pretreatment, dyeing and final finishing The effect of textile preparation technologies (desizing, scouring, bleaching, mercerizing, chlorination etc.) to the water and air pollution. The technologies considerate from ecological aspect, i.e. enzymatic desizing, bleaching of peroxide etc. The dyestuffs inorganic and organic, their negative effect from ecological aspects, i.e. toxicity, carcinogenity, allergic effects, dusting by manipulation and others. The ingredients into dye bath, their residues in waste water and their elimination. The prohibition of the using some dyestuffs. 7. The sources of energy and energy management

Learning outcomes
|
The course is specialised on ecological problems in textile processes. Deals with fundamentals from general ecology and toxicology, environment and global problems including evaluation of state of environment; further the subject goes into influence of the textile industry on environment, problems of textile finishing according to single technology (ecological problems in pretreatment of textiles, dyeing, printing and final finishing) and problems of water in the textile industry, noise, wastes and energy saving. The sbject also deals with environmental policy including ecolabling, ekoauditing, environmental law and international arrangements.
Knowledge lectured subject - theoretically and practically.
