Harnessing the Fourth Industrial Revolution for Water
The “Fourth Industrial Revolution for the Earth” is a publication series highlighting opportunities to solve the world’s most pressing environmental challenges by harnessing technological innovations supported by new and effective approaches to governance, financing and multistakeholder collaboration. We have a unique opportunity to harness this Fourth Industrial Revolution – and the societal shifts it triggers – to help address environmental issues and transform how we manage our shared global environment. The Fourth Industrial Revolution could, however, also exacerbate existing threats to environmental security or create entirely new risks that will need to be considered and managed. Harnessing these opportunities and proactively managing these risks will require a transformation of the “enabling environment”, namely the governance frameworks and policy protocols, investment and financing models, the prevailing incentives for technology development, and the nature of societal engagement.

Alternative Water Treatment Technologies for Cooling Tower Applications
This GSA Proving Ground (GPG) project assessed the performance of three alternative water treatment systems (AWT) for cooling tower water treatment applications at the Denver Federal Center (DFC) in Denver, Colorado. Cooling towers are commonly applied to water cooled chilled water plants in medium to large commercial buildings and are the point in the system where heat is dissipated to the atmosphere through the evaporative cooling process. Cooling towers also consume a large amount of water. Cooling tower related water consumption is one of largest potable water loads within buildings in the United States, with over 26% of water use associated with heating and cooling. Reducing water consumption is a priority for the General Services Administration (GSA) due to Executive Order 13693, Energy Policy Act of 1992, and regional water shortages. These factors have brought about the investigation of cost effective opportunities to reduce water use, such as AWT technologies for cooling towers. The current state of water treatment in GSA buildings is to use conventional chemical based cooling tower water treatment to maintain cooling tower water quality and contract out this specialized service to a third-party company specializing in such service.

Boiler Water Treatment: Lessons Learned
Background
Enormous amounts of water are used daily in boiler water operations. However, water normally contains various levels of contaminants, dissolved solids (minerals) and dissolved gases. These contaminants cause major operational problems and damage to boilers unless they are removed or controlled on a continuing basis. Correct application of chemical treatment programs can eliminate many problems associated with boiler operations. But other problems can and do impact operations.
