Vacuum evaporation and activated carbon filtration enable the recovery of more than 90% of wastewater generated during the pretreatment process.
SAITA, headquartered in Limena (Padua, Italy) and specialised in the design and manufacture of systems for the purification, recycling, and treatment of industrial wastewater, has developed a new compact solution for the treatment and recycling of wastewater generated by paint pretreatment tunnels.
The new containerised module incorporates an EV Series heat pump vacuum evaporator with a treatment capacity of approximately 1,500 litres per day. The container also houses wastewater collection tanks, distilled water storage and transfer tanks, as well as an activated carbon filtration system for the final treatment of the recovered water.
Designed for outdoor installation, the insulated container is equipped with an air conditioning system capable of maintaining operating conditions within a temperature range of +2°C to +40°C. It also features internal lighting and service power outlets. The system can optionally be equipped with remote monitoring via an Ethernet connection, enabling continuous supervision of operating parameters.
Thanks to its heat pump vacuum evaporation technology, the system allows the customer to recover more than 90% of the wastewater, making it suitable for reuse within the pretreatment process.
In addition, the solution concentrates the residual waste requiring disposal, significantly reducing both fresh water consumption and the associated operating costs.
Developed for companies seeking to optimise wastewater management without occupying valuable production space, the SAITA containerised system provides a self-contained, easily transportable solution that is ready for quick outdoor installation.
