Newlisi presents its technology for sewage sludge reduction, energy recovery at WETEX 2022

 

DUBAI, 27th September, 2022 (WAM) -- Newlisi S.p.A. will take part in the Water, Energy, Technology, and Environment Exhibition (WETEX), which Dubai Electricity and Water Authority (DEWA) organises from 27th to 29th September 2022, at the Dubai World Trade Centre.

The Company will present its technologies and describe its environmental, social, and economic benefits. 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.

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 S.p.A..

It is a two-step (acid - alkali) or one-step (alkali) oxidative thermochemical hydrolysis carried out at low temperature (80 C) and atmospheric pressure. Different from another hydrolysis, using an oxidising agent enhances the solubilisation of the organic sludge fraction, thus making anaerobic digestion and dewatering more effective. Among other sludge treatment processes, the Newlisi solution is also very simple and cost-effective to run: it is mostly automatised, it doesn’t require personnel with special certifications, and it has very low maintenance costs.
