Wastewater reuse through RO: a case study of four RO plants producing industrial water' Ro plant.

Image
  Because of water scarcity in some regions of the Netherlands and new environmental concepts of water withdrawal, Dutch industrial water production has been shifting from surface water or scarce groundwater to wastewater in recent years. Because of this transformation, it is important to evaluate the advantages and disadvantages of using wastewater treatment plant (WWTP) effluent as a source to produce industrial water, and to gain knowledge about water recycling and treatment. Reverse osmosis (RO) treatment is mostly used to produce water for industry. Four selected Dutch RO plants producing industrial water are analysed in this paper. Demineralized Water Plant (DWP) DECO and DWP Sas van Gent are using WWTP effluent as source water; DWP Baanhoek and DWP Botlek are producing industrial water from surface water. The alternative water source alters pre-treatment needs and RO operations. Compared to surface water, WWTP effluent requires more pre-treatment to prevent UF and RO membranes f

Design Calculation Of An Reverse Osmosis (RO) Module

Image
  Reverse osmosis  is the most important technique of desalination of brackish (1000-5000 ppm salt) or sea water (about 35,000 ppm or 3.5% salt). Its potential was identified in the 1950s. But commercial exploitation was not possible until the 1960s. The development of high flux asymmetric cellulose acetate membrane by the phase inversion technique of Lobe and Sourirajan (1963) opened up commercial exploitation of this very important strategy of desalination. Currently, over 12,500 industrial scale desalination plants are operating worldwide with an average production rate of about 23 million cubic meter per day of potable water (less than 200 TDS). The largest sea water desalination plant is in Jeddah, Saudi Arabia, having a capacity of 56,800 cubic meter per day of potable water.     Problem Statement And Given Data: It is required to design an reverse osmosis (RO) module for production of 1500  m 3 /day potable water containing not more than 250 ppm salt from sea water containing 34
