Italy-based Newlisi s presenting its technology for sewage sludge reduction and energy recovery at the Water, Energy, Technology, and Environment Exhibition (Wetex), which opened in Dubai today.

 

The event, organised by Dubai Electricity and Water Authority (Dewa), is being held till September 29 at the Dubai World Trade Centre.

 

The company will describe the environmental, social, and economic benefits of its technology. Developed about a decade ago and patented in 38 countries, the Newlisi process allows for over 70% reduction of sludge for disposal and for a significant increase in biogas production when coupled with anaerobic digestion, said a Wam news agency report.

 

The Newlisi process can be exploited in both urban and industrial wastewater treatment plants, with benefits in terms of risk mitigation and operating costs reduction; the solution applies to any plant, whether or not equipped with an anaerobic digester.

 

"Newlisi’s Clean Water, Green Power solution is addressed to owners or operators of wastewater treatment plants. Our technology is now mature, having been deployed in a real scale for almost eight years. The performances achieved in Siena, Lecce and Grosseto demonstrate that we can operate successfully in different plants with very different objectives and characteristics. This is the reason why our shareholders believe in our growth potential, as demonstrated by the new capital injection," said Edoardo Riccio, CEO of Newlisi.

 

It is a two-step (acid - alkali) or one-step (alkali) oxidative thermochemical hydrolysis carried out at low temperature (80 deg C) and atmospheric pressure.
