Ratti Group | Sustainability Report 2022

industrial wastewater is channelled into a
decantation tank in order to separate and
subsequently remove the solid part. It is then
sent to the relevant purification plant, as
authorised and regulated by the contract.
Water deriving from civil use is, however, stored
in a reservoir, drained off and disposed of.
In general, in Romania analyses of industrial
wastewater are carried out annually, as
prescribed.
In 2019 testing was concluded of the chemical
product treatment for reducing the amount of
volatile organic compounds in the decantation
tank. However, at the Tunisia plant, water is not
used for production – it is only for civil use.

In 2022 Ratti SpA BC undertook a campaign to
identify the characteristics of the substances
present in the main water flows within the
departments. The analysis of the data reported
makes it possible to evaluate the possibility of
inserting intermediate purification and recycling
of water, in order to improve not only the quality
of the wastewater arriving at the purification
plant, but also to reduce the total consumption
of water.
