These waters need to be often discharged and they generate the main effluent stream of the finishing department.
Moreover, there are other minor sources of waste waters discharged by the finishing department:
the washing waters used for chemical reservoirs and for piping networks
the waters used to keep clean the roller-coating machines
the exhausted waters of the wet scrubbers.
All these waste waters generate a very polluted effluent, with high concentrations of TSS (total suspended solids) and COD (Chemical Oxygen Demand).
The compact plant SPRAY PACK, expressly designed and engineered by Italprogetti represent the right solution to manage the recycle of finishing waste waters.
The plant is composed of several modules that are elected according to the characteristics of the effluent and arranged in a compact platform so as to make an easy access for the operator.
The main components are:
chemical reactors for coagulation / flocculation,
groups for chemicals preparation and dosage
section of sludge dewatering.
