The first energy and cost-efficient disruptive ZLD Technology for dredged material management, allowing circular economy and zero pollution

Introduction

Dredging is an essential activity to maintain maritime and river routes, as well as for coastal protection against flooding, among other purposes.

Global Dredging Impact

Every year, over 2 Bm³ of sediments are dredged around the world. Notably, 20-40% of these sediments are highly polluted and must be treated before being disposed of in landfills. This is due to the fact that current treatment and separation technologies do not allow for cost-efficient valorization of the water and solids from this dredged material.

Innovative Technology

Water Challenge has developed and patented the first energy-efficient truly Zero Liquid Discharge (ZLD+) technology. This technology is capable of separating 100% of dredged material into fresh water and crystallized solids in one step, without the use of chemicals and with very low energy consumption (less than 20 kWh/m³).

Project Aim

The aim of this project is to develop a pilot plant with a capacity of 10 m³/day to separate and valorize the water and solids from dredged materials.

Future Prospects

This plant will be pivotal in showcasing the technology and business model before scaling it and replicating it across Europe.
