MIT Engineers Turn Desalination Waste into Useful Chemicals

Engineers from MIT have devised a new approach for turning desalination waste into useful chemicals.

Modern desalination processes often leave behind a lot of highly concentrated brine, which is usually disposed of by dumping it back into the sea.

This process requires costly pumping systems which have to be managed carefully to prevent damage to marine ecosystems.

DEWA receives 5 bids for advisory services for IWP desalination project at Hassyan – Dubai

Dubai Electricity and Water Authority (DEWA) has received 5 bids for an advisory services tender for a 120 MIGD (million imperial gallons per day) water desalination project in Hassyan.

This is the first project to use the Independent Water Producer (IWP) model in Dubai. The project will use Seawater Reverse Osmosis (SWRO) and supports DEWA’s efforts to meet growing demand for water in the Emirate.

DEWA received 5 bids from Cranmore Partners from the UAE and UK; Synergy from India and the USA; Deloitte from the USA; PricewaterhouseCoopers from the UK, and Ernst & Young from the UK.

Sharjah’s Sewa completes $4.6mln water supply project Sharjah – United Arab Emirates

UAE – The Sharjah Electricity and Water Authority (Sewa) has completed two water transmission lines project with a capacity of 60 million gallons per day and at a cost of Dh17 million. The transmission lines are from Al Alliah to Al Jubail under the Sharjah Creek.

Dr Rashid Al Leem, Chairman of Sewa, said it is considered to be one of the most important projects carried out by the Sewa to increase capacity of transferring water produced from the water desalination plant to the Jubail area on the other bank of the creek by more than 100 per cent and distributed to all areas of Sharjah, to keep up with the growing urbanisation.

MIT tech could let desalination plants use their own brine waste

When salt is removed from seawater in desalination plants, the byproduct is – not surprisingly – a lot of highly-concentrated salty brine.

Ordinarily, this is just dumped back into the sea, which can harm the environment. Thanks to a new treatment process, however, that brine could actually be used to desalinate more water.

Developed by a research team at MIT, the proprietary system incorporates what are described as “well-known and standard chemical processes.” These include a nano-filtration process to initially remove unwanted compounds from the brine, followed by one or more stages of electrodialysis.

As a result, the brine is converted into useful chemicals such as sodium hydroxide.

Dh17 million project to enhance water supply across Sharjah – Dubai

The Sharjah Electricity and Water Authority (SEWA) has completed two water transmission lines project with a capacity of 60 million gallons per day and at a cost of Dh17 million.

The transmission lines are from Al Alliah to Al Jubail under the Sharjah Creek.

Dr Rashid Al Aleem, chairman of SEWA, said that it is considered to be one of the most important strategic projects carried out by the SEWA to increase capacity of transferring water produced from the water desalination plant to the Jubail area on the other bank of the creek by more than 100 per cent and distributed to all areas of Sharjah, to keep up with the growing urbanisation.

Cities turn to desalination for water security, but at what cost?

Removing salts and other impurities from water is really difficult. For thousands of years people, including Aristotle, tried to make fresh water from sea water. In the 21st century, advances in desalination technology mean water authorities in Australia and worldwide can supply bountiful fresh water at the flick of a switch.

Achieving water security using desalination is now a priority for the majority of Australia’s capital cities, all but one of which are on the coast. Using the abundance of sea water as a source, this approach seeks to “climate proof” our cities’ water supplies.

MRPL’s seawater desalination plant gets CRZ clearance – Mangaluru

The Expert Appraisal Committee for Projects related to Coastal Regulation Zone (CRZ) of the Union Ministry of Environment, Forest and Climate Change has recommended CRZ clearance to the State’s first reverse osmosis-based seawater desalination plant proposed by Mangalore Refinery and Petrochemicals Ltd. (MRPL).

Headed by Deepak Arun Apte, the committee in its 207th meeting on January 25 said that the clearance was subject to MRPL ensuring temporary structures installed for laying pipelines for the 70 million litre per day (MLD)-capacity plant are removed within one month of completing the work.

Dubai plans first solar-powered desalination plant, says Dewa exec at WGS – Dubai

Dubai will seek partners this year to build its first solar-powered desalination plant as the emirate tries to diversify away from burning fossil fuels to increase its water supply, the head of the Dubai Electricity and Water Authority (Dewa) said in an interview.

The plant, using reverse osmosis technology, will have capacity to produce 120 million gallons a day of drinkable water by 2024, Chief executive officer Saeed Mohammed Al Tayer said in Dubai.

Exhibitions seek to fight food insecurity, climate change and reduce wastage

Dubbed “Hands on the Future,” the exhibitions at KICC sought to promote the pursuit of technical and vocational skills as students and instructors from various Technical and Vocational Education and Training (TVET) institutions and various stakeholders demonstrated their capabilities.

The Standard Group PLC is one of the partners in the initiative.
