Affordable Wood Pulp Membrane Turns Seawater into Fresh Water

Mila Luleva — Wed, 21 Oct 2015 15:59:03 +0000

Scientists developed a new cheap and efficient method to turn seawater into fresh water using cheap fiber from wood pulp. Fresh water scarcity is becoming a huge problem for numerous communities around the world. With population and temperatures increasing continuously, more and more fresh water sources dry out or become exhausted, posing a huge threat […]

Microbial Battery Cleans Wastewater, Generates Energy

Mila Luleva — Tue, 03 Mar 2015 13:34:08 +0000

A team of US researchers have found a cost effective way to use a microbial battery for cleaning up wastewater discarded during oil and gas operations. With fresh water scarcity becoming more and more of a problem as we speak, any industry that pollutes the “liquid gold” or wastes it in any way, is the […]

WaterFX’s New Desalination Process Uses Concentrated Solar Power

Mila Luleva — Fri, 28 Feb 2014 16:39:10 +0000

In many parts of the world, including California, South Australia, Qatar, among others, desalination of sea water is a practice, without which the intensity of drought and lack of drinking water would have had an even more devastating impact than what they have now. However, the huge amount of energy that is consumed by desalination […]

Making Saltwater Drinkable: Desalination Already Happening in Nature

Adele Hall — Thu, 10 Oct 2013 04:52:17 +0000

The water crisis in our world today revolves not around water scarcity, but water quality. One of every six people doesn’t have access to safe drinking water. This is ironic considering about 70% of our planet is covered in water. Of course, that water is salt water. The process of desalination has been a very […]

“Water Chip” Nanoscale Desalination Developed at University of Texas

Benji Jerew — Wed, 10 Jul 2013 13:02:10 +0000

Access to potable water is especially critical near the ocean, where overuse of wells can depress the freshwater table and allow saltwater to creep in. Desalination isn’t accessible to everyone though, due to the size and expense of desalination plants. Water filters can be used to remove contaminants from water, including most protozoa, bacteria, and […]

World Food Crisis Solved By Desert Farming?

Leigh Hutchens — Fri, 30 Nov 2012 13:29:27 +0000

Dreamed up and designed by a 62 year old London theater lighting engineer and led by a 33 year old German former Goldman Sachs banker, Sundrop Farms in Port Augusta Australia is growing food in the desert. Sundrop Farms is beyond the experimental stage and has successfully produced agriculture in an environment usually hostile to growing much […]

Portable Desalination System Designed by MIT Could Save Lives

Ovidiu Sandru — Fri, 26 Mar 2010 13:11:09 +0000

Water desalination is very important in areas where earthquakes, tsunamis or other natural catastrophes occurred. Usually, these areas are located near the sea or the ocean, and desalinizing the water could definitely save lives.

SEADOG Uses Waves' Own Power to Desalinate Sea Water

Cristi — Wed, 21 Oct 2009 20:05:40 +0000

A company called Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas. The resulted water will be finally put into corn-based biodegradable plastic bottles. The SEADOG power system is made from a buoy which puts in motion a piston mechanism that rotates a water wheel to generate electricity.

Freshwater and Electricity Through Osmosis

Cristi — Thu, 15 Jan 2009 18:49:24 +0000

Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.

Low Energy Water Desalination Through Nanotechnology

Ovidiu Sandru — Mon, 09 Jun 2008 19:19:00 +0000

The Lawrence Livermore National Laboratory has found out a greener way to desalinize sea water. It uses carbon nanotubes which have pores that are 100,000 times smaller than a human hair, and were able to determine the rejection mechanism within the pores.
