New way to recover almost 100 percent of the water from highly concentrated salt solutions … the researchers developed a self-heating carbon nanotube-based membrane that only heats the brine at the membrane surface. The new system reduced the heat needed in the process and increased the yield of recovered water to close to 100 percent. In addition to the significantly improved desalination performance, the team also investigated how the application of alternating currents to the membrane heating element could prevent degradation of the carbon nanotubes in the saline environment. Specifically, a threshold frequency was identified where electrochemical oxidation of the nanotubes was prevented, allowing the nanotube films to be operated for significant lengths of […] New way to recover almost 100 percent of the water from highly concentrated salt solutionsDME GmbH2017-05-30T10:38:31+02:00

Evoqua Launches Nexed Electrochemical Desalination Demonstration For Brackish Water … The new brackish water installation, which encompasses a 50 gallon per minute Nexed system at the Kay Bailey Hutchison Desalination Plant in El Paso, TX (KBH), builds upon the current Evoqua pilot for seawater desalination underway in Tuas, Singapore. The demonstration will prove out the economics and value proposition of the Nexed technology in comparison to incumbent RO technology with a focus on higher recovery and lower energy consumption. Once the system is fully operational – which is expected in June 2017 — Evoqua and AccelerateH2O will invite stakeholders to visit the site and observe the system and […] Evoqua Launches Nexed Electrochemical Desalination Demonstration For Brackish WaterDME GmbH2017-05-19T16:16:06+02:00
Australia – Victorian Government is ordering minimum amount of 15GL of water from the Victorian Desalination Plant for 2017/18 …. Victorian Minister for Water Lisa Neville said, “The plant was not built to be turned on just when our water supply reached critical levels. Instead its aim is to make sure that our water supply doesn’t fall to those levels in the first place. “No one’s water bills will increase due to this water order. There will be no additional charges for this year’s water orders – or the minimum water orders of 15GL for the next three years – passed onto consumers.” These orders will instead be funded from the sale of surplus Renewable Energy Certificates, which […] Australia – Victorian Government is ordering minimum amount of 15GL of water from the Victorian Desalination Plant for 2017/18DME GmbH2017-05-17T10:31:37+02:00
Renewable energy powered (400 MW) desalination plant in Qatar …. “Sweden and Qatar are negotiating on a water producing project that will be setup in the north of Qatar and it will use only wind and solar energy to desalinate sea water. My meeting with the minister of energy and industry HE Mohammed Saleh Al Sada has been very productive on this subject,” Oscar Stenström, Swedish Vice minister of trade was quoted by The peninsular. The minister said that the proposed water plant would use 200MW of power from wind and 200MW from solar panels. “The cost of water desalination will be as low as $1 per cubic […] Renewable energy powered (400 MW) desalination plant in QatarDME GmbH2017-05-17T10:02:53+02:00
Discussion on the proposal for a desalination plant on the Bluff (South Africa) … “South Africa is experiencing a severe drought like many countries around the world. As a result the desalination method has been selected to satisfy the collective thirst, consequently destroying the environment. The process of desalination uses more fossil fuels than when sourcing comparable quantities of clean drinking water,” added Gomes. The desalination procedure entails two pipelines: One to be utilised to take in sea water and the other to discard waste back into the sea. The intake pipeline emits penetrating sound waves that cause marine life to flee from that vicinity as it vacuums up phytoplankton, fish larvae, fish […] Discussion on the proposal for a desalination plant on the Bluff (South Africa)DME GmbH2017-05-17T09:55:11+02:00

South Africa goes the desalination route to fight water shortage Government says it has launched the largest desalination plant in the country. Richards Bay on the KwaZulu-Natal north coast is the first recipient of the government programme. It will see about 150 000 households as well as water-intensive and smelter companies benefiting from the R300 million plant. The desalination process, converting salty seawater to drinkable water, is seen as a game changer for drought-stricken communities in northern KwaZulu-Natal. Mokonyane says, … (LINK) South Africa goes the desalination route to fight water shortageDME GmbH2017-05-15T12:05:41+02:00
„Akademik Lomonossow“, Russlands erstes schwimmendes Atomkraftwerk auch für Meerwasserentsalzung … Professor Georgij Tichomirow vom nationalen Atomforschungsinstitut „Mifi“ ist begeistert. Wird die Arktis für die Schifffahrt und auch eine Ausbeutung der Rohstoffe zugänglich, könnte Pewek ein guter Stützpunkt werden. „Sollten in der Arktis Ölvorkommen entdeckt werden, ist es logisch, dass dort dann auch schwimmende Atomkraftwerke zum Einsatz kommen“, so der Professor. Die schwimmenden AKW sollen offensichtlich die Infrastruktur liefern, die für das Einrichten kleiner Trabantenorte im Polarkreis erforderlich ist. So sollen sie etwa Meerwasser entsalzen. … Das schwimmende AKW von Pewek soll als Prototyp aber auch zeigen, dass Russland schwimmende Atomkraftwerke bauen kann.

Membraneless water filtration using CO2 … show an alternative membraneless method for separating suspended particles by exposing the colloidal suspension to CO2. Dissolution of CO2 into the suspension creates solute gradients that drive phoretic motion of particles. Due to the large diffusion potential generated by the dissociation of carbonic acid, colloidal particles move either away from or towards the gas–liquid interface depending on their surface charge. Using the directed motion of particles induced by exposure to CO2, we demonstrate a scalable, continuous flow, membraneless particle filtration process that exhibits low energy consumption, three orders of magnitude lower than conventional microfiltration/ultrafiltration processes, and is essentially […] Membraneless water filtration using CO2DME GmbH2017-05-11T12:22:36+02:00
