Wastewater treatment

This paper relates to an experimental investigation about the treatment processes of large quantities of used water from agricultural uses. It is collected after its natural mixing with domestic and industrial used waters, treated according to administrative laws, and drained by gravity into an open

Nowadays, according to new environmental regulations, a reduction of waste volume is required. Because of this limitation, only two ways of elimination will be considered: incineration and land application. In this context, a global energetic study of a wastewater and sewage sludge treatment pilot s

Lead is a highly toxic heavy metal, found in water and air, which should be treated. Lead removal from wastewater is an important problem in battery industries. The separation process by means of electrodialysis (ED) shows several advantages such as highly selective desalination, high water recovery

An investigation of wastewater treatment by ultrafiltration (UF) is introduced. In the experiments a UF membrane (UFPHT20-6338) and samples of Behshahr Ind. Co. wastewater as feed were used. The effect of operating conditions such as pressure difference, cross flow velocity, shear stress, temperatur

In the chromium tanning process leather consumes 60–80% of the applied chromium salt and the rest is usually discharged into sewage without adequate treatment, causing serious environmental impact. Chemical analysis of the spent chromium effluents from two local medium-size tannery shops indicated t

Application of membrane techniques (pervaporation and membrane-based solvent extraction) and adsorption tothe removal of phenol from solutions modelling wastewater from phenol production by cumene oxidation processwas investigated. The transport and separation properties of composite membranes PEBA,

The potential of industrial wastewater reuse in Jordan is discussed. Industrial water requirements, wastewater production, types of pollutants in industrial wastewater and the technologies for wastewater treatment have been evaluated. A total of thirty industries have been reviewed. The total efflue

The experimental results of the pilot scale application of different membrane technologies, supported by clariflocculation and ozonization, for textile wastewater reuse are described. The investigation has been carried out by treating two different textile effluents: a secondary effluent coming from

This article describes a novel process for recovery of aromatic amines and phenolic compounds form wastewaters, the membrane aromatic recovery aromatic system (MARS). Laboratory work on wastewaters containing aniline and phenol will be presented, including data demonstrating removal and recovery of

An internal aerobic membrane bioreactor was developed with submerged flat membrane plates: the internal MEMBIOR. This system has several advantages compared to a conventional wastewater such as: compactness, reduced sludge production and very high effluent quality. Both laboratory and pilot scale in
