A bench scale RO process simulator was operated in a batch concentration mode to determine the effects of product water recovery and feed water temperature on flux, rejection, and inorganic fouling by gypsum scale formation for simulated brackish water. As feed water temperature increased, salt reje

Using the phenol enrichment cultivation method, we succeeded in screening a few bacterial strains with a varied ability for utilizing phenol as the sole carbon source from pharmaceutical disposal wastewaters plant. Among these strains, a potent phenol-degrading bacterium, assigned Pseudomonas sp. SA

The growing scarcity of freshwater is driving the implementation of desalination on an increasingly large scale. However, the energy required to run desalination plants remains a drawback. The idea of using renewable energy sources is fundamentally attractive and many studies have been done in this

Potable water supply has a significant role in today’s developing world. It is very important to determine the specifications of desalination systems in order to achieve cheaper water prices and better operational conditions. Multi-effect desalination (MED) with thermal vapor compressor (TVC) is a p

Salinity gradient power (SGP) is based on the chemical potential difference between concentrated and dilute salt solutions. Reverse electrodialysis (RED) can thus be used to produce electricity by a SGP–RED unit. In principle, a highly concentrated solution can be recovered from a seawater desalinat

The characteristic equation has been used for experimental results of a passive solar still to generate linear and non-linear characteristic equations for winter and summer conditions. The different angles of inclination of condensing cover (15°, 30°, 45°) have been chosen for winter and summer cond

A continuous adsorption study in a fixed-bed column was carried out by using phoenix tree leaf powder as an adsorbent for the removal of methylene blue (MB) from aqueous solution. The effect of flow rate, influent MB concentration and bed depth on the adsorption characteristics of adsorbent was inve

Experimental measurements were conducted to determine the level of natural organic matter (NOM) and its disinfection by-products formation potential (DBPFP) for Tigris River water in Baghdad. The results showed that raw water total organic carbon (TOC) levels have a potential to produce concentratio

Domoic acid ([2S-[2α,3β,4β(1Z,3E,5S*)]]-2-carboxy-4-(5-carboxy-1-methyl-1,3-hexadienyl)-3-pyrrolidineacetic acid, DA), a harmful algal toxin produced by several microorganisms genus involved in red tides, was tested for degradation in de-ionized and synthetic sea water using Fenton and Fenton-like a

Removal efficiency of organic contaminants and reduction of toxicity (Microtox) in the secondary petroleum refinery and pulp mill effluents using two freezing processes, unidirectional downward freezing (UDF) and the spray freezing, was evaluated in this experimental study. The effect of the freezin
