BM-T respirometry study about the adaptation of a potential toxic industrial wastewater to an specific activated sludge case study
Enterprise: CELANESE CHEMICALS IBÉRICA, S.A. (Tarragona – Spain)
Premier materials for painting industry
Celanese enterprise, before the SURCIS study, in several laboratories had already tried several analysis of its industrial wastewater in order to find out if it could be certain degree of toxicity when wastewater will be treated with activated sludge and also to know its biodegradability degree. According to the bioassays and ecotoxicity results from laboratories, the wastewater has got a high degree of toxicity and it would be not possible the construction of a new biological treatment process to remove the COD of such wastewater (!?) SURCIS, by means of its BM-T respirometer demonstrated however that after some controlled period of adaptation to the activated sludge, the wastewater was not only at all toxic but also presented a high degree of biodegradability.
The objective of the study was, therefore, to obtain a clear confirmation on the toxic and biodegradable nature of a genuine sample from Celanese Iberian Chemicals with the purpose of contributing with fundamental data to the future activated sludge process design.
This service was carried out by specialized SURCIS (Spain) personnel by means a BM-T respirometer system and some complementary reagents and instruments.
