Enrichment of sediments in urban rivers by heavy metals


Carlos Roberto Juchen et al. View all

Water Quality

The heavy metals contained in sediments may be responsible for constant degradation of rivers’ water quality, which circulate in an urban environment. Therefore, this study shows the pollution index and enrichment factor for each of these elements in river sediments. It was used the optical emission...

Degree of Wastewater Treatment versus Types of Reuses: Case Study, Saudi Arabia


Gohar Ali Mahar et al. View all

Water Resources Management

The Council of Ministers issued a Royal decree number M/6 1421 H, corresponding to 2000 AD. The decree stated that, in Saudi Arabia, all wastewater should be treated at the tertiary level, without any discrimination (in terms of the type of reuse and discharge locations). The aim of this article is...

The majestic Hadrianic Aqueduct of the city of Athens


Christaki Maria et al. View all

Water Resources Management

Athens in antiquity as well today, included all the settlements in the wider Attica region. That is why its official name was “the Athens” (plural). Since prehistoric times, the city of Athens and the wider region of Attica did not contain many natural water sources so aquatic reserves were never...

Water Solution Polishing of Nitrate Using Potassium permanganate Modified Zeolite: Parametric experiments, kinetics and equilibrium analysis


A.A. Alinejad et al. View all

Water Quality

In the present study, adsorption potential of potassium permanganate (Hypermangan) modified zeolite was investigated for the removal of nitrate from synthetic wastewater. Effects of the most significant parameters (pH, adsorbent dose, nitrate concentration and contact time) were initially evaluated...
