Welcome article on "Alternate Use of RO Reject & Water Management" – December 2015 issue Dear Patron, Greetings from Water Today! I am working on the December 2015 issue and would like to invite you to contribute technical articles, case studies, research papers on "Alternate Use of RO Reject & Water Management" and facilitate a comprehensive perspective on the same. Theme note: Across the globe today, the population is facing a number of water-related challenges from overuse of freshwater resources, environmental degradation, loss of biodiversity, and desertification to how efficiently the water is being used, recycled and reused. Though, the reuse of process water effluent plays a vital role in water resource management, the use of reverse osmosis (RO) to remove salts and impurities from water has been a recognized technology to improve water quality. However, water resource management and the minimization of discharges are also the major concerns in the today’s industries. In an industrial setting, RO is often used to remove total dissolved salts (TDS) from industrial wastewater or treated industrial wastewater and yield permeate with relatively low TDS concentrations. While RO is an effective method for handling wastewater, the concentrate or reject water ~20-50% of the RO feed water volume can be an issue. Specifically, the high salinity in RO concentrate can make it prohibitive for discharge to a local sewer facility. Hauling the wastewater to a treatment facility can also be prohibitively expensive. Typical recycling, reuse and process water systems use RO technology as the method of decreasing the level of ions in process water. RO recovery rates normally range from 50-75%, thus 25-50% of the RO feed water is discharged as wastewater. The increasing cost of water and waste discharge has forced the industries to look for ways to recover and reuse RO reject water. Besides this, the increasing scarcity of water in the world along with rapid population increase in urban areas gives rise to concern about appropriate water management practices. Appropriate technology, legislation and its strict enforcement, public awareness are the key factors for water management. Water management hierarchy includes cleaner production / waste minimization, reuse / recover / recycle, disposal and its challenges are quality requirements, energy requirements, land requirements, and operation and maintenance. Moreover, waste prevention techniques can be commonly summarized as reduction, reuse, recycling and recovery. In order to move towards the sustainable water use, there is an urgent need to reconsider the existing traditional supply-side management approach in all sectors and to raise awareness in society so as to reduce irrational water use. Our December 2015 issue will be focusing on Alternate Use of RO Reject & Water Management . We would like to invite you to share your experiences in the form of articles, technical papers and case studies with our readers. Please inform us of your intent to contribute at the earliest, so that we can evaluate the articles for the publication.
