Funding
This project has been funded by the national programme for clusters support “Ayudas a Agrupaciones Empresariales Innovadoras” (AEIs) of the Ministry of Industry, Commerce and Tourism.
Description
IVERGEST is a decision support system that predicts the behaviour of an industrial discharge in the receiving waterway. Once implemented, it will allow modifying the discharge conditions to reduce its negative effect on the riverbed.
The modification made to the discharge will depend on each situation, including actions such as: temporarily stopping the discharge, altering its frequency, modifying its flow, and selecting other discharge points.
To achieve this, a network of sensors will be installed to monitor strategic points in the waterway. Although this information will be punctual (each sensor only measures in its surrounding area), by knowing the channel’s orographic conditions and hydrodynamic behaviour, it will be possible to extrapolate the behaviour of the discharge using CFD (Computational Fluid Dynamics) simulations. This will be achieved even in different channel conditions, as shown in the following images.
Objectives
The mixing zone is defined as the area from which the homogeneous dissolution of the discharge is achieved. IVERGEST will be able to determine what this zone is thanks to the information provided in real-time by the sensors, which will feed the simulation software (CFD). Once this has been achieved, prediction algorithms and alarm systems can be developed.
The execution of this work includes the following specific objectives:
- Characterize the spill and the receiving medium.
- To model the hydrodynamics of the river computationally.
- To establish the distribution of the sensor network in the mixing zone and the data acquisition system.
- Develop the predictive algorithms.
- Develop the software for monitoring and control of the discharge.
Results
There is currently no system on the market to monitor the effects of a spill in advance. Thanks to IVERGEST, the user will have a tool that will allow him to monitor the spill’s effect in real-time (scope and intensity of the pollutant plume), which will enable him to take different actions to minimise the impact of the spill if necessary.
In this way, the industry will avoid the environmental and economic risks associated with the spill, which are regulated by Law 26/2007 of October 23rd. Additionally, it allows river basin organisations to incorporate this system in the best available technologies for activities subject to European and national regulations on integrated pollution prevention and control (R.D.L. 1/2016).
