Decolourising of Waste Water Technology
Precipitation Technology: InoTEX developed special flocculant that selectively precipitates organic dyes (reactive, direct, acid etc.) present in water. These are converted to insoluble compounds that can be separated from waters by sedimentation, flotation or filtration. Flocculant is as well very efficient with water containing dyes of different technological groups as sulphur dyes, vat dyes etc. Effectiveness of decolourising is about 90%
Separation of Heavy Metal Ions From Textile Waste Waters
A specific feature of textile wastewater is that in some cases the heavy metals used are contained bound in organic complexes. The heavy metals bound in this way then resist the usual removal technologies - precipitation and clarification. InoTEX has developed a special flocculant that converts heavy metal complexes present in textile wastewater into insoluble compounds that can then be separated from the water. At the same time, a significant part of the heavy metals present in ionic form is also removed.

Elaboration of Safety Data Sheets in Accordance With the Regulation 1907/2006/EU
Development of product safety data sheets according to Regulation 1907/2006/EU. The content and form of safety data sheets meet the requirements of European legislation, they can be drawn up in Czech, German and English versions. With safety data sheets, the manufacturer provides information on health, safety, fire and ecological properties, especially of chemical substances and mixtures, on safe methods of handling, use, storage, disposal and measures in the case of an accident.
Special Waste Water Decolourising Flocculants
Flocculants of the
TEXAFLOK DCL series
Use: Intended for decolorizing textile wastewater.
Examples of use: Separated exhausted dye bath, colored rinsing or washing waters are used for dosage. Dosing is also possible into a separate tank or diectly into the machine outflow or into waste water mixture. Separation of precipitates is possible, for example, at a chemical WWTP, in the primary sedimentation or activation tank of a biological WWTP, or at a special sedimentation or flotation device.
Special Flocculant Designated for Separation of Heavy Ions from Waste Waters
Flocculants of the
TEXAFLOK METAL series
Use: Agent intended for the separation of heavy metals from textile wastewater.
Examples of use: Dosed into separated, exhausted finishing bath, or into rinsing or washing water. Dosing is possible into a separate tank or directly into the machine outflow or to waste water mixture.. Separation of precipitates is possible, for example, at a chemical WWTP, in the primary sedimentation or activation tank of a biological WWTP, or at a special sedimentation or flotation device.
Ecological Technologies for Textile Finishing
The introduction of textile finishing technologies (e.g. dyeing) with a higher degree of exploitation of input substances, reduced dosage of auxiliary substances and resulting lower pollution of waste water. At the same time, both pollution and cost reduction are achieved. In cooperation with the company's technologists.
The Best Available Technologies
The ongoing deterioration of the environment calls for changes in the general approach to its protection. One of the important tools to ensure the principle of sustainable development are the principles of an integrated approach to pollution reduction, specifically expressed in the Industrial Emissions Directive (IED) concerning Integrated Pollution Prevention and Control (IPPC). The IED Directive was issued under the number 2010 /75/EU, the new directive , which will replace it was published in July 2024 under the number 2024/1785/EU; the EU Member States now have 22 months to incorporate the provisions of the directive into their national legislation. In the Czech Republic, the majority of the new requirements will be incorporated in the Act on Integrated Prevention, while a small part will be dealt with in the Air Protection Act.
The aim of the Industrial Emissions Directive is to achieve integrated prevention and reduction of pollution arising from important industrial processes. The environmental strategy used in the past, focusing on the protection of individual components of the environment and the protection of nature, led to the wide application of so-called end-of-pipe technologies (separators, treatment plants and landfills), which have proven themselves in solving current environmental problems. However, their consequence is the transfer of pollution from one environmental area to another, and the demands on natural resources and production costs increase, instead of protecting the environment as a whole. A modern environmental protection strategy uses investment measures for cleaner production integrated into production technologies. The IED is based on an integrated approach, which means that the issued permit must take into account the overall impact of the plant on the environment (emissions to air, water and soil, waste generation, use of raw materials, energy efficiency, noise, accident prevention, site restoration activities).
The textile industry is listed in the IED Directive as one of the industrial activities covered by the integrated environmental permit; this must include conditions based on Conclusions on Best Available Techniques (BAT). These are the result of the Commission's exchange of information with experts from Member States, industry and environmental organizations, the output of which are reference documents on BAT (so-called BREF documents) and Conclusions on BAT, which the Commission issues in the form of an Implementing Decision. In January 2023, a revised BREF was issued for the textile industry. The Conclusions on BAT for the textile industry were issued by the Commission in December 2022 as Implementing Decision 2022/2508/EU. These are the basic document for permitting and setting binding operating conditions, especially for setting emission limits. A four-year implementation period for approved emission limits applies from the date of issue; new devices must comply immediately. In connection with this, a review of the issued integrated permits is gradually taking place.
In the textile industry, enterprises that meet the definition of the category of industrial activities listed in Annex I falling under the scope of the IED Directive are:
Pre-treatment (operations such as washing, bleaching, mercerization), dyeing or final treatment of textile fibers or textiles with a processing capacity of more than 10 t per day
Surface treatment of substances, objects or products using organic solvents, in particular finishing, printing, plating, degreasing, waterproofing, dimensioning, dyeing, cleaning or impregnation, with consumption of organic solvents higher than 150 kg per hour or more than 200 t per year.
InoTEX participated in the preparation of the Reference Document on the Best Available Techniques in the Textile Industry through personal representation in the relevant EU working group in Seville. It also has some national reference documents of EU member countries. Information is available on which techniques and technologies are being considered or already defined as Best Available Techniques.
