The paper describes some of the basic principles behind the DEPA Guidelines for discharge of industrial wastewater to public sewers set in operation in 1995 and evaluates some of the experiences with the implementation. It is described how such guidelines support the approach of pollution prevention and the implementation of cleaner technology by putting a stress on the industry. Further an approach for the balance between environmental and technological considerations is introduced. The need for easily understandable environmental priorities is stressed and a concept for this is presented along with its combination with available technology. Finally expression of the environmental requirements are discussed in relation to environmental and technological considerations.

High Treatment

More than fifty wastewater treatment plants worldwide (representing several millions p.e) are equipped with up-flow biofiltration reactors (BioforR). Their range of application encompasses municipal as well as industrial wastewater. A summary of the results achieved in a large number of plants is presented, accompanied by a description of the operating parameters and the treatment limitations with regard to various pollutants (C, N, P). The separation of functions into specific reactors combined with optimized wash conditions guarantees high treatment efficiency.

Exposure Pathways

The tremendous increase in the production and consumption of titanium dioxide (TiO2) nanoparticles (NPs) in numerous industrial products and applications has augmented the need to understand their role in wastewater treatment technologies. Likewise, the deleterious effects of wastewater on the environment and natural resources have compelled researchers to find out most suitable, economical and environment friendly approaches for its treatment. In this context, the use of TiO2 NPs as the representative of photocatalytic technology for industrial wastewater treatment is coming to the horizon. For centuries, the use of industrial wastewater to feed agriculture land has been a common practice across the globe and the sewage sludge generated from wastewater treatment plants is also used as fertilizer in agricultural soils. Therefore, it is necessary to be aware of possible exposure pathways of these NPs, especially in the perspective of wastewater treatment and their impacts on the agro-environment. This review highlights the potential exposure route of TiO2 NPs from industrial applications to wastewater treatment and its impacts on the agro-environment. Key elements of the review present the recent developments of TiO2 NPs in two main sectors including wastewater treatment and the agro-environment along with their potential exposure pathways. Furthermore, the direct exposure routes of these NPs from production to end-user consumption until their end phase needs to be studied in detail and optimization of their suitable applications and controlled use to ensure environmental safety.
