Zero discharge of waste water at Corradi
Corradi is an Italian manufacturer of 'outdoor living' (which is part of the international Renson group), located in Bologna. For the construction of terrace coverings it mainly uses aluminium as a sustainable resource. But aluminium requires a pre-treatment before it can be painted or processed. As part of their acquisition by Renson in 2015, they decided to invest in a new production unit, with a sustainable water purification system. With the help of PCA, they succeeded in drastically reducing both their input of process water and their discharge of waste water. We designed a tailor-made system for them that combines a vacuum evaporator with an ion exchanger in a closed circuit.
