SEOUL, South Korea – An Integrated Waste-to-Water Process (IWWP) has been developed by Doosan Lentjes and the water division of Doosan Heavy Industries & Construction.
Much like thermal desalination units that off-take heat from co-located power plants, the process would direct steam from the incineration of municipal solid waste to be used in the seawater desalination process.
The company said that using the technology, around 300 tons of municipal waste has the potential to generate enough potable water for 100,000 people.
While the announcement lacked detail, Doosan is currently involved in both the thermal desalination market, offering both Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED), as well as Reverse Osmosis (RO) membrane-based water filtration.
Gerhard Lohe, director of waste to energy at Doosan Lentjes, said: “Our advanced IWWP can be optimized for either a higher energy generation or a higher water production – depending on respective requirements.”
This is not the first time the solid waste and desalination markets have crossed paths.
Last year WWi reported that EPC company Hitachi Zosen Corporation was going to combine its solid waste and water desalination businesses for the Middle East market (read article).
Meanwhile Singapore engineering company Hyflux is diversifying from traditional desalination to the solid waste to energy market with a partnership to develop the TuasOne project.
