Experimental design

Forward osmosis (FO) has recently attracted growing attention in wastewater, brackish groundwater and seawater desalination, and power generation. This study evaluates the potential of using a batch laboratory-scale FO system as a pre-treatment for the reverse osmosis (RO) process. FO is a low press

Most widely applied and commercially proven desalination technologies fall into two categories of thermal (evaporative) and membrane based methods. Membrane methods are less energy intensive than thermal methods and since energy consumption directly affects the cost-effectiveness and feasibility of

In this study the effects of operating parameters on the ultrafiltration of metal working fluids were considered and the optimum conditions for filtration were estimated. In order to reduce the number of experiments an experimental design method (Taguchi) was applied. Seven parameters including pH,

In this study, Remazol Black B dyestuff removal from wastewater by ion exchange was investigated with in a batch system and 23 full factorial design was applied. Anion exchanger resin was prepared from agricultural residue (straw) after reaction with epichlorohydrin and dimethylamine in the presence

With the aid of atomic absorption, a systematical and analytical evaluation method called Taguchi’s quality engineering has been applied for the separation of copper ions from a solution using a laboratory electrodialysis set-up to evaluate the optimal experimental conditions and hence to achieve th

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

A study of the effects of some parameters on the active chlorine production from aqueous sodium chloride solutions in the hypochlorite electrochemical production cells was undertaken. These varying parameters included the anodic surface area (Sa), the ratio of anodic and cathodic surface areas (Sa/S

In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi
