This month, tips for including water conservation in your energy-management program, an introduction to mammalian cell culture, pointers for preventing caking of bulk solids, and much more.

How Desalination Created Modern Qatar

. by Kent Harrington

Imagine a country with abundant energy — primarily gas and oil — but lacking almost any drinking water (ground or surface), which is essential for the cities, infrastructure, and in Qat

A Novel Forward Osmosis Draw Solution

. by Martin Bergstedt

Although significant research efforts regarding new membranes for forward osmosis are underway, less attention has been paid to researching the draw solutions and solutes that could make this techn

World Café: Energy Water Food Nexus at the 2014 Annual Meeting

. by John Vasko

The World Café will focus on the global grand challenge of energy, water and food. The session aims to build awareness of the challenge and highlight the roles chemical engineering expertise can play in addressing the systems integration and technology needs resulting from the interconnected nature of these global issues. The discussion will continue on AIChE's Linkedin Group.

April 2014 CEP Preview

This month, CEP turns an eye to industrial water reuse. You'll also find best practices for pilot-plant piping, a look at Italy's chemical industry, and much more.

Arsenic: “King of Poisons” in Food and Water

. by Fatima Enam

For centuries, arsenic has been known to be a classic poison, causing deaths of many historic figures. While now just a murder-mystery cliché to many, arsenic is still actually causing harm, with dangerously high levels in food and water around the world.

Finding Cheap New Energy Under America's City Streets

. by Kent Harrington

America's decaying water infrastructure might actually provide an opportunity to generate cheap, green energy. Lucid Energy has demonstrated a way to install in-pipe water turbines that are amazingly efficient, and American cities such as San Antonio, TX, are planning to give the new technology a try.

Is Safe, Clean Fracking Possible?

. by Douglas B. Clark

The good news is that, yes, fracking can be made safe and clean, according to a new analysis by the International Energy Agency (IEA). But the down side is that it probably will take tougher regulations to make all producers to apply the latest technologies.

Forward Osmosis Pilot Plant for Seawater Desalination

. by Martin Bergstedt

Forward osmosis offsets some of the high costs of reverse osmosis, but large-scale systems necessarily introduce one or more additional unit ops to recover the extracted water from the draw solution utilized. Young Kim of the Korea Institue of Machinery and Materials (KIMM) discussed her work on a forward osmosis pilot plant.

Produced Water Treatment with Ceramic Membranes

. by Martin Bergstedt

The volume and complexity of produced water (PW) generated in the oil and gas extraction industry provides a significant separations and treatment challenge. Because of its source, PW is contaminated with hydrocarbons and inorganic leachates from the rock strata where the well is drilled. Bruce Bishop of Veolia Water presented the results of ceramic membrane systems trials in different process environments.

Moringa Oleifera Seeds for Water Treatment in Water-Stressed Areas

. by Martin Bergstedt

The challenge of improving water quality in water-stressed areas of the world may have a natural champion in the Moringa oleifera tree. More specifically, a particular protein found in the meal of dried and ground M. oleifera seeds, when adsorbed onto sand, has shown some excellent preliminary results in removing total suspended solids (TSS) and in killing coliform bacteria.
