In the past, industrial infrastructures were developed within a context of unconstrained water resource availability. This is no longer the case. Unsustainable uses of water resources and population dynamics along with climate change affect this critical resource, which is becoming scarce. The EU-funded intelWATT project (Grant agreement ID 958454), coordinated by NCSR Demokritos, will develop innovative, cost-efficient, smart separation technologies applied in energy- and water-intensive industries. Three case studies in electricity production, mining and electroplating facilities will demonstrate water preservation along with energy production and material recovery.
IntelWATT aims to develop innovative, cost efficient, smart separation technologies applied in energy and water intensive industries. The goal of the project is to demonstrate 3 TRL7 case studies that will achieve water preservation along with energy production and material recovery. The proposed solutions will also target at zero liquid discharge while implementing maximum water reuse. Tailor made sensors and automated decision making mechanisms will optimize the process conditions in real time. The case studies will be implemented in crucial EU and global industrial applications such as electricity production, mining and metal plating.

-Case study 1: Demonstration prototype for CTBD treatment. The development of efficient, cost effective, smart solutions for water management in a thermoelectric power plant, aiming at minimization of the cooling tower blow down (>99% recovery) trough developing a pilot unit of 100 m3/day treatment capacity installed in the premise of PPC’s unit V (natural gas combined circle facility, Megalopolis, Greece) based on a closed loop, near zero liquid discharge approach.

-Case study 2: Demonstration of a symbiotic concept between industries: sustainable production of energy and water. In this context, an integrated pilot unit (100 m3/day) comprised by Reverse Electrodialysis (RED) and solar powered membrane distillation (MD) systems.

-Case study 3: The application of a novel, hybrid high recovery RO (HRRO) / Ion exchange (IX) resin prototype will demonstrate the recovery of valuable electrolytes and fresh water preservation in a plastic electroplating facility. The process is aiming towards recovering up to 95 % of Chromium and Copper and 50% of Nickel, while preserving 65% of fresh water.
Implement smart sensor technology for online monitoring, real time process adaptation and deep learning, with customizable intelligent industrial process software module based on an agnostic protocol connectivity cloud infrastructure.
