Decolourising of Waste Water Technology

Biological Treatment

Biological treatment is the most often used technology for removing organic waste water pollution. Dyes that are used in textile production aren't biologically degradable and so biological treatment is almost without effect. The effect of decolourising is about 5% in praxis. Dyes are sorpted and when draining dregs sediments away they get loose and get back to the waste water.
It's possible to gain 80% effectiveness of waste water treatment by activation, by changing technological conditions of treatment on the basis of Inotex patent. Slight anaerobic step is placed to the beginning of the activation with continuous flow, where dyes are biodegraded to non-coloured compounds. Denitrification step follows and clearing is finalised by common aerobic activation. The technology is developed for the occurrences of soluble reactive, direct or acid dyes in waters. Common clearing methods (as clarifying) have limited effectiveness.

Recipitation 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

In some cases textile waste waters contain heavy metal ions fixed to organic complexes. These heavy metal ions are often resistant to common clearing technologies as precipitation and clarifying.
InoTEX developed special flocculant that converts heavy metal ion complexes contaminating textile waste waters to insoluble compounds that can be easily removed from waters in next step. Considerable portion of heavy metal ions in ion form is being separated simultaneously.

Consultancy and Testing (ecolabeling) of Products

Consultancy and advisory for acquiring certification within national program "Ecological product". Providing of contacts to Ministry of Environment, which assigns certificates. Preparation of documentation and advancements of conformity evidences. Producer labels his products with certifications to show customers ecological and healthiness unobjectability of its products and fulfils environmental legislation. Test-room is on EURATEX list, consortium of European clothing and textile producers, recommended for Euro-ecolabeling of textiles. InoTEX is author of Czech version of directive for ecolabeling of Ecological Product. Directive is in harmonisation with European directive. National certification holder simultaneously fulfils European criteria. European ecolabel covers larger field of textile production then other system on lower level. Holder fulfils as well criteria for other ecolabels on lower level.

Implementation of Cleaner Production Systems

Legislative requirements for environmental protection get more and more strickt world-wide. This leads to increasing "dead expenditures" into clearing technologies. Industry responded by setting up eco-effective concept. That means by integrating technologies to production with both positive effects - ecological and economical. Methodology developed in USA as prevention of creation of waste and pollution called as well as minimalization of waste became the most spread methodology used "Cleaner Production".
Essence of this preventative approach is trivial and everyone approves it. It's more profitable to prevent creation of pollution and waste than take care of it after it is produced. System of step by step decisions, which respects economical availability of producer, was developed for implementation of prevention methods. Many qualified experts who can serve as consultants or auditors are at disposal at Inotex for implementation of Cleaner Production System.

Consultancy with Implementation of Environmental Manager Systems (EMS) in accordance with ISO 14000 and directives of EU 1836/93/EEC

Consultancy with EMS creation in accordance with directive EU 1836/93/EEC, or ISO 14 000. Producer proves to its customers, administrative and autonomous organs applicability of ecological technologies and operability of managing system that takes in account environmental impacts.

Environmental Impact Appreciation (EIA)

Environmental Impact Appreciation in accordance with the law 244/92 Sb. In accordance with the law the appreciation is in some cases obligatory and in others is voluntary. EIA documentation's main goal is to objectively appreciate if the investment arrangements are in accordance with valid legislation and what will be the impact on individual parts of the environment in the region. The main goal of the documentation is to alert already in the phase of project preparation about inconveniences in environmental impact and make proper arrangements so that it fulfils the strictest criteria for environmental protection and long-term development. In accordance with the law, independent expert's opinion on documentation is needed to prevent possible lacks. A qualified expert, certified by Ministry of Environment, is at disposal at Inotex.

Certified Tests of Biodegradability

Certified test-room for biodegradability in organic substances. Replacing of non-degradable substances by degradable substances in production can have serious economical impact because of increasing prices paid for disharging waste waters containing non-degradable substances measured by CHSK method.

Elaboration of Safety Lists in Accordance With the Law 157/1998 Sb

Elaboration of safety lists of products in accordance with the law 157/1998 Sb and directive of EU 93/112/EC. Safety lists meet contents and form requirements of EU. We can provide them in Czech, German and English version. By providing safety lists the producer informs about healthy, safety, fire and ecological properties of chemicals especially. Provides information about safe manipulation methods, use, storage, disposal and emergency plan. They are commonly required during business contacts. We are certified in accordance with law 157/1998 Sb. to handle dangerous chemicals and chemical preparations.

The Best Available Technologies

Continuous deterioration of environment calls for changes in general approach to its protection. One of the important instruments securing principle of continuous development are principles of integrated approach to lowering of pollution expressed in directive 96/61/EC., concerning Integrated Pollution Prevention and Control (IPPC). The main goal of this directive is to reach integrated prevention and limiting the pollution arising from important industrial processes. Environmental strategy used till now aiming at prevention of single components of environment and nature protection lead to wide use of "end-user technologies" (separators, cleaners and waste sites) that helped solving actual problems of environment. But consequence is only shifting of pollution from one part of environment to the other and higher demands for natural resources and production cost instead of environmental protection as a whole. Modern strategies of environmental protection use investment instruments of cleaner production integrated to production technologies. Textile industry is on IPPC list as one of industrial activities that belongs to integrated environmental permit. In textile industry this concerns companies that meet the definition of industry activities listed in the directive in the supplement 1.
  • Enterprises for pre-preparation (operation as washing, bleaching, mercerizing) or fibre or fabrics dyeing whose modification capacity exceeds 10t daily

  • Apparatuses for surface modification of cloths, objects or products using organic solvents, especially finishing, printing, metallizing, degreasing, waterproofing, redimensioning, cleaning or impregnating with capacity of production higher than 150kg per hour or higher than 200t a year.

Ministry of Environment, in co-ordination with European legislation, made a proposal of IPPC law. Inotex as a member of expert group of Association of Industry and Transportation participates on suggestions of the proposal. We also have a member in working group of EU in Sevilla that prepares Reference Documents about the best available techniques in textile industry. Some national reference documents of EU countries are at disposal in Inotex as well as information about which techniques and technologies are being considerated or were defined as The Best Available Techniques.
