4 The Quarterly March 2019 Water. desalination + reuse The Quarterly The US Department of Energy brought out its Energy-Water Desal Hub funding, as innovation continues to fl ourish worldwide UNITED STATES Poseidon defeats legal challenge to Huntington Beach project Sacramento Superior Court, California, rejected a lawsuit demanding that developer Poseidon produce a new environmental study on the proposed Huntington Beach Desalination Plant project. The suit argued that the developer should conduct an entirely new Environmental Impact Study (EIS) for the project following changes to the proposal. The original EIS was completed in 2010. The State Lands Commission had already determined that Poseidon need only complete a supplemental report addressing the changes. The suit was brought by the California Coastkeeper Alliance, the Orange County Coastkeeper and the California Coastal Protection Network. UNITED STATES Tesla develops custom wastewater reuse technology Tesla has published a patent for a wastewater treatment technology that it hopes will reduce operating costs. Tesla's manufacturing processes produce high volumes of wastewater that is concentrated with sodium and sulphate ions. Disposing of the wastewater is costly. The patent — System for Regenerating Sodium Hydroxide and Sulfuric Acid from Wastewater Stream Containing Sodium and Sulfate Ions — describes a new way to handle it. The system includes electrolysis treatment and three membrane concentration systems confi gured in a series of chambers. It recycles wastewater for reuse in the manufacturing process. UNITED STATES US DoE unveils $100 million for Energy-Water Desal Hub The US Department of Energy (DoE) unveiled a fund of $100 million to establish an Energy- Water Desalination Hub. The long-awaited hub will focus on early-stage research and development in energy-effi cient and low- cost technologies for treating non-traditional waters. The fund is for one fi ve-year award. The aim is to meet goals in four technical areas: materials research and development, new processes research and development, modelling and simulation tools, and integrated data and analysis. US secretary of energy Rick Perry hosted a roundtable discussion at the White House in March 2018 to explore use of prize competitions to drive technological innovation. In October, he unveiled the Water Security Grand Challenge. Perry said: "Technological achievements generated through the hub will help us to achieve several strategic goals established through the Water Security Grand Challenge. By focusing research and development eff orts on advancing transformational technologies that promote cost-eff ective desalination, we are working towards meeting the national and global need to secure, aff ordable water," said Perry.
