This work investigated the evaluation of a pilot-scale membrane bioreactor (MBR) system in combination with a reverse osmosis (RO) unit. The MBR treatment with biomass concentration (MLSS) of 5 mg/L provided a high level of treatment for primary municipal wastewater. The removal of SS reached 99.99%

A novel spectrophotometric assay method using home-made reagents that can be used to determine the chemical oxygen demand (COD) in real wastewater is described. The home-made reagents were used instead of the American Hach reagents. The principle of measurement was based on direct determination of t

Batch sorption experiments were conducted with cadmium and lead ions at low equilibrium concentrations in 0.01 M of NaNO3 onto Petra clay in single component systems. The equilibrium isotherms were determined at pH 6 under constant ionic strength and at different temperatures. The experimental data

The Hamma (Algeria) desalination plant, briefly described in the paper, was mathematically modelled in order to check its behaviour in an advanced phase of its design. The plant will employ 288 ERI’s PX units to recover the pressure of the brine discarded from the RO membranes. This way of recoverin

This paper utilized wind speed data over a period of almost 10 years between 1977 and 1988 from three stations, Adrar, Timimoun and Tindouf, in order to assess the energy output for a 30 MW installed capacity wind farm at each site in Algeria in terms of gross energy, renewable energy delivered, spe

The influence of three different types of dissolved organic carbon (DOC) on fouling of a PVDF ultrafiltration membrane modified by nano-sized alumina was studied in this work. Raw water was taken from two different locations of the Song Hua River. Some raw water was used directly as the feed of the

A carbonaceous nanofilter was fabricated by a continuous spray pyrolysis method by using n-hexane as a carbon source and ferrocene as a catalyst source. Different parameters such as catalyst concentration, temperature, gas flow rate and reaction time affecting the purity of synthesized carbon nanotu

The bio-stability of ultraviolet disinfected reused water from a tertiary biological wastewater treatment plant was investigated, using laboratory-scale simulated static water pipelines. UV disinfection was found not to be able to maintain its disinfection effect over a few days, such that the total

The use of low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. Orange peel was collected from the local fields of orange trees and converted into a low-cost adsorbent. The present study deals with the r

Packed bed of polypyrrole/polystyrene sulfonate (PPy/PSS) electrodeposited porous carbon electrode was prepared and used for continuous water softening from flowing artificial hard water solutions. Careful preparation of the packed bed was performed in order to obtain the greatest possible degree of
