A coupled advanced oxidation-biological process for recycling of industrial waste waters containing persistent organic contaminants

Since first European directive in 1975, much progress has been made in tackling point source contamination of Europe ‘s waters. But sever pressures remain regarding Priority Hazardous Substances, PHS [DECISION No 2455/2001/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 20 November 2001 establishing the list of priority substances in the field of water policy and amending Directive 2000/60/EC]. Human health is threatened by high concentrations of pesticides, heavy metals, hydrocarbons, chlorinated hydrocarbons, etc. dissolved in water which source is usually industrial wastewaters containing PHS at low-medium concentration (<500 mg/L). In this context, the IPPC Directive (96/61/EC) has requested the development of technologies and management practices for specific industrial sectors (see Annex I of the Directive) for the minimisation of pollution and for the development of water recycling. Due to the lack of available on-site treatment technologies, a large quantity of the industrial activities included in Annex I of IPPC Directive are not treating these wastewaters appropriately. As consequence, simple, low cost and at hand technologies are strongly necessary. CADOX is addressed to develop a suitable technology that could fulfil this gap. CADOX technology will focus on non-biodegradable chlorinated solvents (NBCS), biocides and plant protection products, considered as PHS and which producers are included as objective of the IPPC Directive implementation.
