Five submerged macrophytes, C eratophyllum demersum , E lodea canadensis , P otamogeton crispus , Myriophyllum spicatum and Vallisneria spiralis were selected and their relative growth rate (RGR) and the capacity of removing phosphorus in greenhouse were evaluated by hydrotropic experiments of two s

The ability of untreated local rubber wood sawdust (RWS) to remove Cr(VI) was carried out under a bench-scale shaking condition by varying parameters such as initial Cr(VI) concentrations, adsorbent dosage, pH, temperature and eluting agent. Complete Cr(VI) removal was achieved at pH less than 2, in

Based on experimental data, a simulation and optimisation of the adsorption Á microfiltration (AMF) process for boron removal from reverse osmosis (RO) permeate was done. An impressively low flow rate of the dry boron adsorbent of about only 54.3 kg h(1 is needed in the adsorbent recirculation loop

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H3PO4 (AC1), 50% ZnCl2 (AC2) followed by pyrolysis at 600°C an

Humic acids are primarily a result of the microbiological degradation of surrounding vegetation and animal decay and enter surface waters through rain water run-off from the surrounding land. This often gives rise to large seasonal variations, high concentrations in the wet season and lower concentr

A flat type membrane bioreactor (MBR) with a pore size of 0.038 μm and having a total surface area of 540 m2 was operated intermittently for over a year in METU campus at Ankara to treat domestic effluents from dormitories and academic village. At the first stage the MBR plant was operated continuou

Acetic acid is a compound commonly found in hemicellulosic hydrolysates. This weak acid strongly influences the bioconversion of sugar containing hydrolysates. Previous investigators have used anion exchange resins for acetic acid removal from different hemicellulosic hydrolysates. In this study, th

Platinum and other platinum metals have been widely applied in industry. The recovery of noble metals from industrial wastes becomes an economic issue. The laboratory studies of removal of platinum (IV) microquantities from 0.1–6M hydrochloric acid solutions on the ion-exchangers of the functional q

The effects of treatment and conditioning on sepiolite for the removal of Co2+ and Ni2+ from aqueous solutions were investigated by using a batch-type method. Effects of factors such as pH, concentration, stirring time, stirring speed and sorbent amount on adsorption were investigated. The initial a

There has been great demand for development of technologies that remove toxic heavy metal ions from wastewater. Chemical precipitation operation is known to remove heavy metal ions from water. In this study applicability of alkaline reagents such as Ca(OH)2 (lime) and NaOH (caustic soda) in removing
