Reverse osmosis (RO)

An integration of water vane pump and hydraulic vane motor was introduced in small reverse osmosis (RO) system, in which the hydraulic vane motor was used as energy recovery device. The hydraulic performance and energy consumption of one combination of pump and hydraulic motor were investigated unde

In the present work, one type of reverse osmosis desalination plant with 2.5 t/d product was introduced. An experimental study was carried out, the result of experiment was analyzed. The calculation data using ROSA software developed by Dow Chemical company was given. By regression analysis of the e

The electronics industry generates large amounts of fluoride-containing effluents. The objective of this study is to study the feasibility of applying reverse osmosis (RO) membrane separation to reduce fluoride load to less than 1 kg/d. The effect of transmembrane pressure on the removal of fluoride

The decision to use a desalination system as well as the selection of the most appropriate combined energy source depends on several parameters. The main are the low investment, the low maintenance requirements, a simple operation and a high reliability. This paper discusses the costs dependence fro

A two-chamber hydraulic energy recovery unit with a programmable controller and a data acquisition system was set up. Tap water was used as the working fluid instead of the actual seawater and concentrate in SWRO desalination plants. Experimental results were obtained on the fluctuations of the pres

A landfill leachate treatment plant (LLTP) in Korea was retrofitted to improve treatment efficiency by using integrated membrane process that is composed of membrane bioreactor (MBR) and reverse osmosis (RO) process. In general, proper treatment of landfill leachate is difficult for its refractory c
