Wastewater

In this study the wastewaters originating from solid waste transport stations that are established to compress the collected solid wastes from households in order to ease further transportation to final disposal sites (e.g. sanitary landfills) were investigated in terms of characterization and treat

Struvite, magnesium ammonium phosphate hexahydrated (MAP) (Mg NH4 PO4.6H2O) is a white inorganic crystalline mineral that can be used as a slow releasing fertilizer. The present study evaluated the feasibility of using bittern as a by-product of salt manufacture, as a low-cost source of magnesium io

As water resources become more limited and waste discharge becomes increasingly problematic, the concept of water reuse is becoming important. Recently, use of greywater and rainwater as alternative water resources has drawn attention. However, lack of useful information on the combined use of greyw

In an effort to make wastewater recycling risk-free, this research investigated the feasibility of using a waste material as filter for the removal of humic substances (HS), and ultimately the toxic hydrophobic organic compounds (HOC) attached to them. Based on the results of earlier studies, labora

We considered the treatment of secondary effluent by coagulation–adsorption coupled with ultrafiltration. Tests were performed on the secondary effluent of the wastewater treatment plant at Staoueli (Algeria) where the average chemical oxygen demand (COD) was 46 (mg O2/L) and turbidity, 16 NTU. The

The electronics industry generates large amounts of fluoride-containing effluents. The objective of this study is to study the feasibility of applying reverse osmosis (RO) membrane separation to reduce fluoride load to less than 1 kg/d. The effect of transmembrane pressure on the removal of fluoride

The cellulose hydrazone derivative is a novel product prepared from dialdehyde cellulose with 2-hydrazino3,5,6,7tetrahydrocyclopentanethieno[2,3-d]-pyrimidin-4(4H)-one under suitably selected conditions. It was found that the reaction of dialdehyde cellulose with the 2-hydrazino derivative decreased

Tanning of hides and skins to convert them into leather can have a considerable environmental impact. Wastewater treatment technology can successfully purify leather wastewater. The first part of this research investigated the influence of Al2(SO4)3 concentration on the velocity of tannery wastewate

The investigation was undertaken to evaluate the effectiveness of using activated carbon (AC) in conjunction with ultrafiltration (UF) in the removal of methylene blue (MB) from aqueous solutions. The combination of activated carbon with UF in this work was to exploit the high adsorption capabilitie

With the aid of atomic absorption, a systematical and analytical evaluation method called Taguchi’s quality engineering has been applied for the separation of copper ions from a solution using a laboratory electrodialysis set-up to evaluate the optimal experimental conditions and hence to achieve th
