Neotec UV developed open channel low-pressure, high-output ultraviolet (UV) disinfection system equipped with cleaning device operated by submersible rodless cylinder (NOL-HA Series) in 2005 and obtained Excellent Performance Certification from Korean government agency in 2009. Since then, Neotec has installed UV system at many wastewater and reclaimed waste- water treatment plants in Korea.

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,

Condensate polishing During the production process of basic organic chemicals, very often condensates occur as byproducts, which have to be treated before dumping or recycling into production process. The condensate occurring at the product process of caprolactame contents for example ammonium sulfate and caprolactame. The loss of these products instead of recycling would not only mean a reduction of the process recovery, but also very high costs for waste water treatment. These condensates can be concentrated by a reverse osmosis plant. Because of the high salt retention rate of the reverse osmosis membrane, nearly all contents of the condensate are separated and can be brought back to the production cycle. The filtered permeate can be dumped into the municipal waste water system without hesitation. In some cases, the recirculation of the separated contents is not appropriated. In this context, reverse osmosis helps reducing the volume of the accruing condensate. The remaining conden
