Firms to showcase new water desalination model

Manama, January 13, 2014

A new water desalination technology that delivers energy and cost savings and reduces environmental impact will be introduced in Bahrain on Wednesday, the promoters of the system said yesterday.

Bahrain-based MIT International and British chemical firm Genesys will showcase 'Genairclean' during a technical seminar on "Reducing the cost and optimising the performance of reverse osmosis desalination systems", which is being held at the Gulf Hotel from 10am to 1pm, said a report in the Gulf Daily News (GDN), our sister publication.

Speaking at a press conference at the Ramada Palace in Gudaibiya, officials from the two companies said Genairclean is an enhanced reverse osmosis membrane cleaning system.

"The technique combines multiple cleaning mechanisms - chemistry, effervescence, direct osmosis and micro-bubbles - to improve the removal of deposits from membranes," Genesys International's David Golding told the GDN.

"Membrane systems will periodically experience fouling from biological growth, inorganic scale deposits or suspended colloidal matter, particularly when the source water is recycled from processes such as effluent treatment," he said.

"Such fouling is often difficult to remove and the industry has been striving for better cleaning techniques to improve the degree of cleaning and extend the system's time in service."

According to him, with the launch of Genairclean, Genesys was advancing the art of cleaning and providing a mechanism to deal with difficult to remove foulants.

Golding said reverse osmosis is an increasingly common method of desalination because of its relatively low energy consumption.

"Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination.

"Up to 50 per cent of the sea water input can be recovered as fresh water unlike conventional thermal evaporation and condensation systems that delivered only 10 per cent efficiency," he said.

Golding said Genesys worked globally through a network of distributors in countries where water desalination and purification were prime requirements, both for industrialisation and often, life itself.

MIT International's managing director Muhammed P K said the company is the authorised distributor for Genesys in Bahrain. - TradeArabia News Service
