Research Abstracts

The xenobiotic organic compounds linear alkylbenzene sulfonates (LAS) are among the most thoroughly investigated with respect to biodegradability. Previous studies have shown that LAS are relatively rapidly degraded under aerobic conditions, but only very slowly or not at all degraded under anaerobi

The paper summarizes the current situation of urban wastewater treatment plants (UWWTP) in Turkey. Results of a detailed survey on the performance of four selected plants were given both in terms of influent and effluent quality and in comparison with the current legislation on discharge limits to r

Performance and behaviour of a subsurface-horizontal flow constructed wetlands (SSF-h CW) used for sewage post-treatment behind an upflow anaerobic reactor under Moroccan climate conditions are reported. The experimental setup included three parallel beds of 28 m2, each receiving 9.5 m3 d−1 of pre-t

In this study, sites irrigated with wastewater for 10, 5, and 2 years and site not irrigated were sampled for soil and plant chemical analysis to evaluate its long term effect. Long term wastewater irrigation increased salts, organic matter and plant nutrients in the soil. Soil pH was not consistent

The ability of natural zeolite (clinoptilolite) and exfoliated vermiculite to remove copper from aqueous solutions was studied in fixed bed column and batch reactors. The effect of agitation speed (0, 100, 200, 400 rpm), temperature (25, 45, 60°C), and particle size [2.5-5.0 mm, dust ( clinoptilolit

The aim of this study was to investigate the application of sequencing batch reactor (SBR) technology for treating grey water collected at outlet of showers room of students. The performance of SBR was satisfactory as the effluent had respectively 20 and 5 mg/L of COD and BOD. Applied two hydraulic

GIS and expert knowledge are used as a decision support system to determine adequate potential soil aquifer treatment (SAT) sites for groundwater recharge of Hammamet–Nabeul aquifer located in ‘Cap Bon’ peninsula in North East of Tunisia. These sites are identified using a single-objective multi-cri

The solar photocatalytic decolorization and degradation of Maxoline Navy 2 RM 200% basic dye in aqueous solution with TiO2-A (pure anatase) as photocatalyst in slurry form have been investigated using solar light. The removal of the dye was strongly enhanced by the addition of electron acceptors suc

The experimental and theoretical study of a solar desalination system located in Cairo, Egypt, is presented in this research. A modification unit is provided to enhance the performance of the solar desalination. The modification unit includes a solar parabolic trough (solar energy concentrator) with

A small-scale stand-alone solar-driven membrane desalination unit was designed and manufactured under project funding agreement number ICA3-CT-2002-10025 (SMADES). The desalination plant is intended for autonomous operation in arid and semi-arid remote regions with a lack of electricity and drinkabl
