Bookmarks: The Atlas of Water

Bookmarks: The Atlas of Water Mapping the World’s Most Critical Resource by Maggie Black, Jannet King foreword by Margaret Catley-Carlson, Global Water Partnership The Atlas of Water Climate change and an exponential population explosion threaten the world’s supply of fresh water, edging us closer to a global water crisis, with dire implications for agriculture, the economy, the environment, and human health. Completely revised and updated since its first edition, The Atlas of Water is a compelling visual guide to the state of this life-sustaining resource. Using vivid graphics, maps, and charts, it explores the complex human interaction with water over time and across the world. This vibrant atlas addresses all the pressing issues concerning water, from human impacts like dams

Optimizing Polymer Mixing in Water and Wastewater Treatment

Optimizing Polymer Mixing in Water and Wastewater Treatment A major concern in water and wastewater treatment processes is identifying the most effective and efficient way to remove solid particles and other materials found in the liquid stream. The most effective method of eliminating unwanted contaminants is through the use of polymers in a sludge-creating process. Polymers are used to coagulate suspended solids and produce large curds of solid materials (floc) which are more easily removed from the water treatment stream. Polymers are available in a variety of forms and concentrations and are supplied as either dry powders or concentrated liquids. Each variation presents unique challenges when sizing mixers. Dry Polymers: Polymers supplied in powder form must be wetted out which

Extraordinary Water Treatment Innovation

Extraordinary Water Treatment Innovation Aqua Recovery Project The conversion and repurposing of old tanker ships may just be the ultimate in recycling programs. According to a DNV GL research project, phased-out tank ships are part of a water treatment solution that can provide much needed clean water for coastal cities. In April 2013, Sigmund Larsen, CEO of tech start-up EnviroNor, approached DNV GL CEO Henrik O. Madsen with the idea of converting “old tankers” into floating treatment plants. A project group was assigned, and after ten months of research and planning, the project is ready for its pilot run. “We have to think differently if we want to solve the global challenges related to water supply and pollution from discharge

Elixir: A History of Water and Humankind

Bookmarks: Elixir A History of Water and Humankind By Brian Fagan In Elixir, New York Times bestselling author Brian Fagan tells the story of our most vital resource and how it has shaped our history, from ancient Mesopotamia to the parched present of the Sunbelt. Fagan relates how every human society has been shaped by its relationship to our most essential resource. This sweeping narrative moves across the world, from ancient Greece and Rome, whose mighty aqueducts still supply modern cities, to China, where emperors marshaled armies of laborers in a centuries-long struggle to tame powerful rivers. As the earth’s population approaches nine billion and ancient aquifers run dry, we once again remember the importance of this vital resource. To solve the water

Selecting Wastewater Mixers for Wastewater Treatment – Part 1

Selecting Wastewater Mixers for Wastewater Treatment – Part 1 Wastewater Mixers for Optimal Chemical Preparation Chemical preparation in wastewater and water treatment directly impacts many downstream processes. Let’s take a look at several common chemicals used and some key factors that influence their preparation and the selection of wastewater mixers. Lime Slurry Preparation When preparing lime slurries for controlling pH, uniformity is critical. Why? Because lime solids must reach/stay in suspension if they are to serve their purpose in downstream processes. For this reason, it’s essential that wastewater and water treatment facilities have lime slurry mixers that can efficiently and effectively make up/maintain uniform slurries. In order to successfully suspend/re-suspend solids, a mixer needs to create a flow pattern that involves the entire

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2 Waste Water Mixers for Optimal Flash Mixing & Flocculation In part 1 of this series on wastewater and water treatment mixers, we discussed how to select a waste water mixer for chemical preparation. In this post, we’ll show you how to select a Waste Water Mixer for flash mixing and flocculation. Done in a Flash? Aggressive Agitation + Speed for Flash Mixing Flash mixing is used to evenly distribute coagulating chemicals in water, allowing micro-flocs to form. As the precursor to flocculation, flash mixing increases the efficiency of flocculation and reduces chemical wastage. Because the components need to be quickly and evenly dispersed, this process is all about brute
