Removal of bis (2-ethylhexyl) phthalate from reject water in a nitrogen-removing sequencing batch reactor

Article Abstract:

Removal of nitrogen and bis (2-ethylhexyl) phthalate (DEHP) from reject water was studied in two sequencing batch reactors (SBRs) with different aerobic/anoxic periods during a 6-h total cycle period. Results show that SBR has the potential to cut the internal load of nitrogen and hydrophobic organic pollutants in cases where reject water is circulated to the headworks of a sewage treatment plant (STP).

Mapping hazard from urban non-point pollution: A screening model to support sustainable urban drainage planning

Article Abstract:

The development of a non-point source preliminary planning and assessment model designed for application to urbanised river basins in North West Europe and the United Kingdom is reported. It is advised that sustainable drainage systems (SuDS) must be installed in existing built areas if diffuse loadings are to be reduced.

A fuzzy knowledge-based decision support system for groundwater pollution risk evaluation

Article Abstract:

A decision support system to provide information on environmental impact of anthropic activities by examining their effects on groundwater quality is proposed. It uses fuzzy logic to take into account the uncertainty of the environmental domain.
