The BRÜCKNER hotflue is the heart of a continuous dyeing range and depending on the customers’ requirements it can be supplied with oil or gas heating. Due to the intelligent drive concept and a sophisticated air flow control an exact shade homogeneity is achieved across the length and the width of the fabric. Tailing and migrations are prevented and the dyeing results are 100% reproducible. This line is appropriate for all woven fabrics, particularly shirting and trouser fabric as well as home textiles such as bed linen. Benefits are among others best dye uniformity over the complete length and width of the fabric, no tailing, no migration, creasefree production, 100% reproducible dyeing results, minimum consumption of thermal and electrical energy, tailormade solutions for a maximum productivity even with small quantities, easy access for cleaning and maintenance due to large doors.

Recovery of flexoprint dye Picture: printing dye (red); ultrafiltrate (orange); nanofiltration permeate (clear) Application: Conditioning and concentration of cardboard printing dyes (flexo print), e.g. paper bag manufacturing, corrugated board manufacturing. Conditioning of the rinse waters by ultrafiltration(UF): Recovery and recycling of dyes, separated by tonality Further conditioning of the permeate by nanofiltration(NF): Recovery of the rinse water Further conditioning of the UF-concentrate by evaporation / distillation as pre-stage for external disposal Advantages of the process: Recovery of dyes separated by tonality is possible and established Recirculation of the rinse water is possible and established Reduction of the waste water amount At existing waste water treatment plants (based on precipitation) amounts of sludge can be reduced enormously Compact and modular design Fully automized process - low personnel costs High degradation rate and efficiency (concerning CSB, Cu,

Dye and product desalination Membrane filtration plants of OSMO Membrane Systems GmbH offer various solutions for desalination. Hereby, we offer all stages of projecting – from proof of concept to costumized plant – from a single source. In times of increasing energy and raw material costs, desalination can be a remarkable contribution in the process chain, to cut running costs and to conserve resources. At the production of dyes, e.g. azo dyes, optical brightening agents (OBA) and so on, nano filtration plants are used for retention of pigments and elution of the present neutral salts (Na+Cl-). At the first production step, the content of sodium chloride will be reduced by dia filtration and addition of deionized water until the required salinity of permeate is reached. The proper selection of the NF membrane achieves the highest possible dye retention at the remaining NF concentrate. After this step, dye can be concentrated to the required values. So, different steps of production c
