Membrane processes use semipermeable membranes and pressure to separate salts from water. Reverse osmosis plant membrane systems typically use less energy than thermal distillation, which has led to a reduction in overall desalination costs over the past decade.

Squeezing Water From the Sea

Squeezing Water From the Sea

By forcing salt water against polymer membranes that trap salt ions and allow fresh water through, reverse osmosis (RO) desalination is an effective water treatment technique. It is relatively expensive, however, due to the energy used to push water molecules through the membrane. But a remarkable facility in Israel, is

A Material World

A Material World

Increased water demands against the backdrop of challenges on water sources are necessitating pipe infrastructure projects to ensure the reliable delivery of water for the long term. A major consideration for every potable water project is choosing from among the variety of pipe materials on the market. With reclaimed water

Reuse: Global Reach, Local Impact

In just 14 years, the United Nations estimates the world will only have 60% of the water resources it needs, if we do nothing different. Obvious solutions to water scarcity can include water reuse, wastewater reclamation, and conservation. But, what if we are just hitting the tip of the iceberg

Desalination in the Age of Water Scarcity

Desalination in the Age of Water Scarcity

At least a dozen different desalination technologies exist. Distillation was the first—used thousands of years ago, and the most common through the 1990s. The process involves evaporating water by thermal or vacuum methods, thereby leaving solids behind, and condensing the desalted vapor into liquid form.

Tampa-Proof?

Tampa-Proof?

Water’s been scarce lately, and with the drought exacerbating problems throughout the Southwest, many cities are looking at spending more to get what they need. They can import water from long distances, mandate conservation measures (as the entire state of California has been doing for months), recycle wastewater, or turn

Drought-Proof Design

Drought-Proof Design

Perhaps no one captured the vision as well as John F. Kennedy.
“If we could ever competitively, at a cheap rate, get freshwater from saltwater,” he said in a 1961 press conference, “it would be in the long-range interests of humanity, which would really dwarf any other scientific accomplishments. I am

Desalination Plants Subject to Stainless Steel Corrosion

Desalination Plants Subject to Stainless Steel Corrosion

Stainless steel is widely used in critical components of drinking water, wastewater, water reuse, and desalination treatment and conveyance systems. Contrary to popular belief, stainless steel can be prone to failures due to corrosion, including microbiologically induced corrosion (MIC). In fact, utilities have had issues with chloride and chlorine corrosion
