A predictive model for a water purification process integrated in an absorption heat transformer, using an artificial neural network, is proposed in order to obtain on-line predictions of the coefficient of performance (COP). This model takes into account the input and output temperatures for each o

Membrane fouling in membrane bioreactors (MBR) is caused by cake formation on the surface, mainly attributed to suspended solids, and also by surface adsorption connected with pore blocking, attributed to soluble components of activated sludge. In this study, long-term experiments were carried out i

This paper aims to examine the separation of ultrafine titanium dioxide (TiO2) ptotocatalyst from its aqueous suspensions and its reuse by cross-flow ultrafiltration (CFU) process. Initially, the effects of various parameters, such as feed concentration, transmembrane pressure, cross-flow velocity,

A supported liquid membrane (SLM) contains organic solvent and organic extractant as one organic phase, and a porous support structure. It has been widely investigated for separation and purification of various chemical compounds. SLM has high permeability and selectivity, being regarded as one of t

Activated carbon was developed from coconut coir pith using ZnCl2 and investigated to assess the possible use of this adsorbent for the removal of sulfate from water. The influence of various parameters such as agitation time, sulfate concentration, adsorbent dose, pH and temperature has been studie

Ultrasound was applied to the control of membrane fouling development on-line in an anaerobic membrane bioreactor (AMBR). Experimental results showed that the higher the sludge concentration, the longer the ultrasonic irradiation time should be for membrane fouling control. When the AMBR operated un

Transport of metal ions through supported liquid membranes has been investigated. A general dimensionless model for mass transfer coefficient is proposed which consists of diffusional, equilibrium and process parameters also properties of the membrane. Nine dimensionless equations for mass transfer

Decision support software (DSS) for Water Treatment for Reuse with Network Distribution (WTRNet) has been developed within the AQUAREC project on “Integrated Concepts for Reuse of Upgraded Wastewater”, under the Fifth European Community Framework Programme. The overall objective of work conducted as

The inhibition performance of three synthetic amine/ammonium-containing cationic polymers in colloidal silica particle growth is reported. The three additives are compared to control (no additives present during silicate polymerization). The three polymers, polyethyleneimine (PEI), polyallylamine hy

A seawater desalination plant’s reliability and service availability are essential to sustain and allow the continuing development in the arid climate countries. As desalinated seawater is indispensably required at any cost, the conventional disposal method used for a large size desalination plant i
