Pilot plant

Membrane distillation (MD) is a hybrid thermal-membrane desalination process that uses low-grade waste heat and hydrophobic membrane to produce high quality distillate. The MD process can treat highly saline brines that other conventional desalination processes cannot treat. These unique features of

• We compare drinking water treatment systems, a NF unit and a conventional treatment. • Sustainable water quality improvement using renewable energy is demonstrated. • Membranes are more efficient than conventional treatment removing micropollutants. • Membranes reject hydrophobic compounds causing

The present paper describes pilot plant development of a novel process enabling increase of water recovery in brackish water desalination without using any chemicals. This is achieved by precipitating the scaling salts of a carbonate-rich concentrate by increasing the pH through air stripping of CO2

There has been great demand for development of technologies that remove toxic heavy metal ions from wastewater. Chemical precipitation operation is known to remove heavy metal ions from water. In this study applicability of alkaline reagents such as Ca(OH)2 (lime) and NaOH (caustic soda) in removing

In this paper the results of an applied research project within the scope of the transfer centre 4031 funded by the German Research Foundation (DFG) are presented. In cooperation with the Henkel Genthin GmbH investigations have been made on the application of UF/NF membrane processes for the separat

The need for good-quality water in Cyprus continues to be the driving force for the use of reverse osmosis to desalinate brackish water and seawater for irrigation and potable use. Much work continues both to optimize the process designs for new plants and to refine the operation of existing ones. T

Toray Industries and Toray Engineering have developed a new type reverse osmosis (RO) membranes and its process for seawater desalination, which brings advantages of high water recovery, low energy cost and lower plant installation cost. The new type RO membranes, “Brine Conversion Reverse Osmosis M
