Reuse

Endocrine disrupting chemicals and pharmaceuticals represent two classes of emerging contaminants that are ubiquitously present in municipal wastewater effluents. Some of these contaminants have been shown to impact aquatic organisms at trace concentrations (i.e., ng/L). Moreover, the public has exp

A wind-driven reverse osmosis system for aquaculture wastewater treatment, developed at the University of Hawaii at Manoa, was tested at the experimental facilities on Coconut Island, Oahu, Hawaii. With this technology, a fish tank becomes a closed aquaculture production system with zero waste disch

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

A novel process was developed to repeatedly utilize MgNH4PO4·6H2O (MAP) for ammonium removal from wastewater by releasing ammonium in MAP through acid dipping. In acid solutions, ammonium can be released to solution from MAP while MAP was transformed to MgHPO4, which can be used to remove ammonium a

Water scarcity in Mediterranean areas such as Comunidad Valenciana (Spain) makes water reuse necessary in high water-consuming industries. Previous studies by our research group showed that nanofiltration (NF) membrane permeates could be reused in some processes of finishing, dyeing and printing in

There are many water shortage problems currently in the world, some of which are more serious than others. All have different solutions. In several of them membrane technology can make a great contribution since membranes have the ability to produce water of exceptional purity that can be recycled f

This study aims to find news a die of purification for a wastewater reuse. Primary effluent contains organic mineral, dissolved and suspended matter (colloids). Microfiltration or ultrafiltration is adequate for producing disinfected clear water suited for different applications. However, direct fil

The selection of an optimum scheme for treatment of agricultural drainage water for reuse in specific applications is a challenging and tedious task that necessitates the evaluation of a long train of optional treatment processes which involve, among others, alternative desalting systems. The decisi

In Tenerife, Canary Islands, a complex infrastructure exists, whose aim is the reuse of wastewater for crop irrigation. For this reason, techniques of advanced treatment, such as micro-ultrafiltration, have been developed. A laboratory-scale study was carried out to evaluate the feasibility of a com

Increases in population and water use are increasing pressures on conventional water sources. The use of alternative sources for non-potable applications can relieve some of this demand. Poor quality ground water, combined with quantities of grey water and rain water, was identified as potential alt
