Toxic wastewaters are a danger to humans and the environment. Within TP 2 approved chemical and physical treatment technologies for decentralized, near-to-source detoxification of industrial wastewater are adopted to the specific constraints in Vietnam and demonstrated by a containerized pilot system. In addition the test of some innovative approaches under local conditions is planned.
The variation of substances in industrial wastewaters allows no general decision for only one or two treatment methods; in most cases different methods have to be combined. Within the project, the most efficient combination of technologies and methods has to be found out. The following state of the art treatment methods for detoxification have been taken into consideration: mechanical separation, precipitation and flocculation, adsorption with activated carbon, filtration with e. g. membrane, biological treatment (e.g. SBR, moving carriers), chemical and advanced oxidation with H2O2, etc.
Based on the identification of relevant industries and toxic wastewater flows, a concept for an adopted pilot system is developed and designed. Constructed by industrial partner HST, the pilot system will be installed and operated on site of a pesticide processing company. By optimization and evaluation, general concepts with focus on chemical and physical treatment methods for the detoxification of highly loaded industrial wastewater are elaborated.
