Electrocoagulation as a pretreatment for reverse osmosis for potable water from brackish groundwater
Reverse osmosis (RO) is a widely utilized method for water treatment and desalination. Our study examined the application of an electrocoagulation (EC) and RO hybrid system for treating actual brackish groundwater (BGW), focusing on reducing RO scaling by EC pretreatment. A series of EC operating conditions were investigated, such as applied voltage, pH, EC reaction time, and type of electrode. The commercial software WAVE was utilized to analyze the water quality to assess the scaling potential of the EC pretreated feed stream for the San Antonio Water System (SAWS) BGW desalination plant. The SAWS BGW desalination process involves a three-stage RO process. Our findings indicate that pretreatment with EC effectively prevents membrane scaling when compared to feed without EC. We conducted continuous EC experiments which showed stable performance and the potential for future commercialization.

Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
