Research Abstracts

A distributed parameter method was developed to calculate diffuse phosphorus emissions at the scale of small watersheds based on relative pollution potential and transmission coefficients. Utilizing digital base maps covering the whole territory of Hungary as well as equations and parameters found i

The problem of water pollution from small livestock producers (non-concentrated animal feeding operations) could be addressed through water quality regulations that apply to additional livestock producers. However, in adopting modified federal water quality regulations, the costs of mandatory contro

The “convention for the protection of the Mediterranean Sea against pollution” (Barcelona Convention), which was adopted in 1976, entered into force in 1978. Turkey is one of the contracting parties of the Barcelona Convention. In this study, the sectoral plans as a part of the preparation of “natio

This study is part of a large-scale project aimed at rehabilitation of the Israeli Coastal Aquifer. Development of a regional 3-D, transient flow and transport model of the hydrological system in the vicinity of the Dan Region Sewage Reclamation Project (SHAFDAN) is presented. The SHAFDAN facilities

Diffuse pollution generated from the coastal tourism areas is one of the significant threats for the marine environment. Besides the accommodation facilities discharging the generated wastewater into the sea without any treatment, the summer resorts of the coastal areas also deteriorate the coastal

Diffuse nitrogen pollution caused by irrigated agriculture is quantified for the Pocochay stream located in the Aconcagua watershed in the Valparaíso region, Chile. The study area has an extent of 93 km2 with 36 km2 under irrigation. It is representative for the central part of Chile where intensive

The implementation schedule for the EU water framework directive requires the creation of monitoring programmes for water bodies according to the intensity of the pollution risk by the end of 2006. Until 2009 river basin district management programmes have to be established followed by the implement

Following the creation of the first reverse osmosis (RO) membrane in the 1960s, the technique has been widely used for the purposes of both small scale and municipal seawater desalination. Forward osmosis (FO) is now also emerging as a possible contender, with the potential for much lower energy con

This study investigates the effect of cationic polyelectrolytes on the final properties of synthetic and activated sludge. Synthetic sludge was prepared according to established procedures. Activated sludge was produced in a labscale, continuous-flow reactor which was fed with live activated sludge
