  • Special chemical-physical process treats Tata Steel`s wastewater

    Tata Steel Europe manufactures several types of packaging steel. One of the types is Electrolytic Chromium Coated Steel (ECCS). Until recently, a chemical containing chromium-6 was used to manufacture ECCS. Annex XIV of the REACH prohibits the use of chromium-6 with effect from 21 September 2017. It remains possible to apply for an exemption, but only a temporary one. Tata Steel looks to offer ...

  • A study on fluorescence properties of carboxymethyl-quaternary ammonium oligochitosan and its performances as a tracing agent

    Carboxymethyl-quaternary ammonium oligochitosan (CM-QAOC) exhibited high inhibition to scaling and microbial formation and also remarkable fluorescence. In this paper its fluorescent properties and application as a fluorescent tracing chemical for industrial water treatment were studied in detail. The fluorescence intensities of CM-QAOC were in good linear agreement with its content in the ...

  • Assessment of the use of red mud as a catalyst for photodegradation of bisphenol A in wastewater treatment

    This study aimed to investigate the use of red mud (RM) – a byproduct of aluminum production, as a photocatalyst, which was characterized physical-chemically and used in the photodegradation of the target compound bisphenol A (BPA). Chemical processing was performed in the RM (acid treatment, chemical reduction and calcination) to verify the most active catalyst. From the results obtained, a ...
