The fluoropolymer coating for special tank systems and containers. Modern tank and environmental technology requires safety and cost effectiveness. Gutbrod stands for innovative ideas and a dedication to service in coating with fluoropolymers and other technical, high-performance materials. Using products with the name, a chemical and acid resistant inner coating that is sustainable and cost-effective can be applied to special tank systems and containers through an access port. The material for this Fluorpolymer-coating, which will be applied with a specific method, is highly resistant against chemicals and acids, and has extraordinarily advantages, compared with common coating and lining systems.

Disposal of oil emulsions by ultrafiltration Increasing disposal costs and laws about oil disposal make a treatment of oily emulsions right necessary right where they come up. The main target of this treatment is the reduction of waste volume as much as possible. Ultrafiltration is one possibility to separate even stabile emulsions. Like chemical methods and flotation, ultrafiltration can not be used as stand-alone solution. Only by an effective pre-treatment and a pre-treatment of the oily concentrate, an optimized and economical emulsion disposal can be guaranteed. By the pre-treatment, coarse particles and free oil is separated; the pre-separation dewaters and concenctrates the flow, which comes as concentrate from the ultrafiltration. So, a maximum of dewatering and concentration of the oil can be reached. The emulsion is pumped through the membrane modules of the plant. On the membrane surface, oil is separated from the waste water. Waste water will pass the membrane and is colle

Acid recovery out of pickling acids Salts and acids can be concentrated or separated from solutions by electrodialysis. For this, ions (anions and cations) are transported through the ion exchange membranes by the applied electrical field. Typical examples for the usage of electrodialysis are: Acid recovery at pickling lines Recovery of metals out of electro-plating rinsing water

Landfill leachate treatment Landfill leachate must not be leaded to the canalization or the recipient untreated. According to the guidelines of environmental protection, waste water hast to fulfill limit values of introduction and reusable water has to be cleaned and separated to be used as process water or maybe as drinking water. So, also landfill leachate – as many other industrial waste waters, too – has to be treated in a way, that introduction into a downstream sewage plant or recipient is according to the law. The multitude of ingredients of the landfill leachate has to be concentrated as much as possible, so that they can be bailed compact and without negative results for the environment. For the treatment of landfill leachate we offer the following processes of conditioning: Treatment of the leachate to reach recipient quality and concentration of the remaining ingredients in a way, that they can be leaded back to the landfill considering the water balance. Water analysis of

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,
