Membrane Free Volume Characterization
Free Volume in Reverse Osmosis Membrane Reverse Osmosis (RO) is the leading technique for water desalination. RO membranes have been optimized over the past three decades. Typically, commerical RO membranes can produce drinking water from seawater. Water and salt transport through RO membrane follows the so-called Solution-Diffusion Model. Particularly, during separation, water and salt ...

History of Electrodeionization
Electrodeionization (EDI) history extends back to the mid-1970’s in the USA. Possibly back to Argonne National Labs in the 1950’s as a scientific novelty. However, the first working EDI modules were made by Harry O’Hare in 1977 and 1978, and were tested by the Southern Research Institute (SRI). The concept was “filled-cell ED”, an attempt to use the ED concept to ...

Seawater desalination for methanex
Methanex has a large methanol production facility in Punta Arenas, Chile. In this region of the world, fresh water is not available, and the facility requires seawater desalination to provide drinking water and process water. When the facility underwent renovation and expansion of their facilities, Aqua-Chem ICD provided a total of five (5) new Once through Multi-stage Flash plants. The Problem ...

A New Generation of Water and Wastewater Treatment for Workforce Housing
Modular solutions like Fluence’s Aspiral and NIROBOX allow treatment to move along with work sites The temporary workforce housing market has come a long way. Back in the early 1900s, construction workers at the Hoover Dam lived in an infamous shantytown of tents, cardboard boxes, and tin scraps. Nowadays, workers at oil and gas, construction, infrastructure, and mining sites expect ...

Preliminary evaluation of new green antiscalants for reverse osmosis water desalination
Supplying fresh water has become an important environmental and economic issue. Desalination with reverse osmosis (RO) represents an effective solution to meet the challenges of cleaning brackish water and seawater for drinking and industrial purposes. The principal problem of RO plant operation is the precipitation of low soluble salts (scaling). There are some well-known techniques to ...

HF Pure Water visits the Middle East
HF Pure Water recently participated in the Water, Energy, Technology and Environment Exhibition held in Dubai, UAE. In speaking with numerous people that visited the HF Pure Water booth, it became apparent that there were limited opportunities for waste water treatment as many manufacturers simply dumped their wastewater into the ocean. This was confirmed in a meeting held with the Dubai ...

Reverse Osmosis Desalination Technology in the Oil & Gas Industry
OFFSHORE INDUSTRY NEEDS FOR POTABLE WATER Offshore platforms are located in some of the most remote, inhospitable environments on the planet. At any given moment, more than two hundred people may be living and working on a platform, each requiring gallons of potable water for diet and sanitation. Freshwater is also required for operations aboard a platform. In fact, the main ingredient in most ...

What is Potable Water and How is it Treated?
What is potable water?If you can drink it or cook with it, it’s potable. Potable water is classified by the World Health Organization (WHO) as water that is not contaminated with organic, inorganic, radiological, or microbiological pollutants and does not present any differences in taste, smell, or appearance. A majority of the earth’s population has regular and convenient access to potable ...

Can saltwater quench our growing thirst?
An increasingly water-stressed world takes a new look at desalination. It seems simple enough: Take the salt out of water so it’s drinkable. But it’s far more complex than it appears at first glance. It’s also increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, climate change and more. That’s ...
