A water reuse system in wetland paddy was simulated to supply water for industrial in this paper. A two-tank model was employed to represent the return flow of the wetland paddy. Historical data were performed for parameter estimation and model verification. With parameters estimated from the data, the model was then used to simulate a reasonable return flow rate from the wetland paddy. The sim...

The main aim of this research is to determine optimal leaching conditions; Eh, pH and complexing agent concentrations, for recovery of Copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. This has been preceded by a theoretical approach and numerical and computer calculation. Pot...

A commercial titania ceramic nanofiltration membrane unit with a permeate flow capacity of 20 m3/h was used to reduce ion concentration, Total Suspended Solids (TSS) and Organic Carbon (TOC) in recycle water from Canadian oil sands mine. This unit, the first its kind, tested for almost two years evaluate performance under actual process conditions. paper focuses on results at 50% stage cut. str...

Mijangos, F. and Diaz, M., 1990. Ion exchange recovery of metals from waste water of complex sulfide hydrometallurgy. Hydrometallurgy. 23: 365-375. The treatment by ion exchange ol' waste water from comples sulfide hydrometallurgy has Iwen studied. Several commercial resins have been tested for a range of pH in solution. The equilibrium results with an iminodiacetic resin for the multicomponent...

According to Watergy (2009), about two or three percent of the energy consumption in the world is used for pumping and water treatment for urban and industrial purposes. The con‐ sumption of energy, in most of water systems all over the world, could be reduced at least 25%, through performance improvements in the energy efficiency. Hence, it is noticeable the importance of development of models...

INTRODUCTION Anaerobic technology have been successful applied for industrial waste water treatment. High reaction rate per unit volume by retaining the biomass in the reactor independently of the incoming waste water flow and concentration. Often high volumetric loading rates in the order of 10 to 40 kg COD/m.d are used. High rate anaerobic biological reactors may be classified into three broa...

several common approaches are used for disinfection of water in this section, but using the approaches (e.g. chlorination) are accompanied with hazardous by-products and also lead to notable changes in odor and flavor of water. gamma irradiation as an emerging method has been encouraged currently by fao/who for water, wastewater and food treatment. coliform bacteria belong to common contaminant...
