Growth and nutrient uptake of seven tree species were evaluated with the goal of selecting the species that can be used for wastewater enhancement by dendro-purification, or green tree filtering, and for restoration of riparian woodlands. Trees were grown in pots with an inert mixture of perlite and vermiculite and irrigated with either nutrient solution or treated wastewater We measured the ef...

Potable reuse is one of the alternatives to approach water sustainability and it is gaining widespread acceptance all over the world due to increasing stress on water resources (Rodriguez et al. 2009). As water reclamation and potable reuse is a viable option, constituents that might threaten human health must be considered seriously. Endotoxins, interchangeably named Lipo-polisccharide (LPS), ...

An electronic microtongue using an electrochemical microcell was designed to monitor wastewater quality. The planar electrochemical microcells were micromachined in a microcrystalline Boron Doped Diamond (BDD) thin layer using a femtosecond laser. The electrochemical measurements with these BDD microcells were conducted using Differential Pulse Anodic Stripping Voltammetry (DPASV) for the major...

Over 90% of the water supplied in the coastal region in Israel in 2013 (600 Mm(3) y(-1)) will be from desalination plants. The wastewater generated from this water (>400 Mm(3) y(-1)) is planned, after proper treatment, to be reused for agricultural irrigation, making this low-salinity water the main agricultural-sector future water source. In this respect both the Mg(2 + ) concentration and the...

The article compares the efficiencies of coke plant wastewater treatment in the integrated systems that combine physicochemical and chemical purification methods with ultrafiltration and reverse osmosis. The wastewater treated came from the “Coke Plant Czestochowa New”. In the process of volume coagulation the coagulant used was sulfate (VI) iron (III)-PIX-113, with the dosage of 400 mg/dm and ...

We examined the effects of chlorine disinfection on Escherichia coli and Salmonella typhimurium in secondary-treated wastewater to determine whether such treatment might induce these bacteria into the viable but nonculturable (VBNC) state. In this state, cells lose culturability but retain viability and the potential to revert to the metabolically active and infectious state. To examine the eff...

Depletion of water supplies for potable and irrigation use is a major problem in the rural wadi valleys of Saudi Arabia and other areas of the Middle East and North Africa. An economic analysis of supplying these villages with either desalinated seawater or treated wastewater conveyed via a managed aquifer recharge (MAR) system was conducted. In many cases, there are no local sources of water s...

AIMS To measure the microbial removal capacity of a small-scale hydroponics wastewater treatment plant. METHODS AND RESULTS Paired samples were taken from untreated, partly-treated and treated wastewater and analysed for faecal microbial indicators, i.e. coliforms, Escherichia coli, enterococci, Clostridium perfringens spores and somatic coliphages, by culture based methods. Escherichia coli ...

Biosorption has attracted attention as a cost-effective means for the treatment of metal-bearing wastewater. While using novel biosorbents, optimization of operating conditions becomes more important for the efficiency of the process. In this study, a novel biosorbent i.e banana peel were used for biosorption of Sn2+ from aqueous media. The effect of various parameters, such as, contacts time o...

Background & Aims of the Study: The use of urban wastewater in agriculture is receiving renewed attention with the increasing scarcity of freshwater resources in many arid and semiarid areas, despite its associated health and environmental risks. Long term wastewater usage for irrigation results in accumulation of heavy metal in soils and plants. So, due to the environmental and health risks as...
