we produce studies and projects to optimise industrial water consumption
Optimisation of the water cycle in industrial settings is characterised by three major activities:
The water analysis stage starts from activity-based analysis covering all actions involved in water procurement, distribution, processing, treatment and disposal in any physical form, from liquid to vapour. Modelling by sets and subsets makes it possible to describe complex systems by subdividing them into simple diagrams, which are the ideal basis for preparing material balances.
The balance is determined using the activity-based model. As a rule it includes, in addition to the water balance, the heat and material balance, referred to the main pollutants present.
Optimisation actions target supply systems, distribution networks, use points and wastewater collection and treatment systems. We design the improvement plan in several phases, each of which includes the specific actions to be implemented, the realisable aims and the associated investment and operational costs.
In production sites undergoing remediation, we evaluate the feasibility of adding optimisation elements. The principle we apply is to increase water reuse across the production cycle, introducing treatment at the optimum points of the wastewater network for recovery and reuse.
Contaminated sites: operational and environmental optimisation.
Reuse of extracted groundwater as process water
The choice of reusing groundwater as process water must be assessed and agreed with control agencies, and must be based on a feasibility study assessing the cost of disposing of the contaminated groundwater, and the investment, operation and maintenance costs for treating such water.
Another factor to consider is temperature.
Groundwater is at a constant temperature of between 15 and 18 °C irrespective of seasonal cycles. Therefore, it can be useful for cooling process fluids, as it makes it possible to optimise operational parameters and improve plant performance. The end result is additional energy savings during plant operation.
Hence, reusing extracted groundwater delivers a number of clear benefits.
They include: reducing the consumption of water by industrial processes, by reusing a resource that would otherwise be treated as waste, with the associated environmental impacts and costs; reducing energy consumption, hence CO2 production; optimising the investments necessary for remediation; and achieving overall savings in industrial processes.
