Dust collection at height in a marine environment
The Bunge project at TERMAG involved supplying bag filters to collect dust during the unloading, loading, handling and storage of raw materials for fertilizer production at the marine terminal in Guarujá, Brazil.
This project predates Kleema’s acquisition of Tersel’s technology and customer portfolio.

The challenge: fitting filtration into the available space
Layout and space restrictions required the filters to be installed on top of the warehouses, at heights exceeding 30 metres. The solution called for integration between structural engineering and filtration process design, considering equipment locations and the dust collection and discharge routes.
Humidity, salinity and sticky material
The marine setting added two challenges. High humidity and airborne salts required attention to corrosion protection of steel surfaces. Humidity also encouraged fine materials to agglomerate and adhere, raising concerns about deposits in ductwork and blocked discharges.
The solutions adopted
Structural platforms supported the filters above the warehouses. The system incorporated self-cleaning bends to reduce material deposition and agglomeration, a special four-coat paint system for corrosion protection, and PTFE (Teflon) applied to hoppers and discharge valves to reduce adhesion and the likelihood of blockage.
Engineering shaped by site conditions
The case brings together structural support, capture, dust conveyance, surface protection and discharge decisions. The challenge extended beyond the bag filter itself: the complete installation had to suit the available space, installation height and marine environment.
