TYPICAL CASE HISTORIES


 

SPILL-SORB  Case History 1
Construction Surprise at the Southern Sun Hotel, Cape Town

In January of 1996, routine construction of the new Southern Sun Hotel in Cape Town, South Africa unexpectedly became a proving ground of the effectiveness of Spill-Sorb. While drilling for 30 metre deep concrete piles, a major pocket of Bunker Oil was struck, flooding the area. The site had previously been a tank farm, and the oil likely came from a long-forgotten pipeline fracture.
As the tide rose, the mixture had to be pumped out to enable concrete production to continue. Spill-Sorb was used as the filtration media; only clean water. as shown on the next page, reached the harbour.

When the Spill-Sorb in a tank became saturated, the flow was diverted to the next tank. The spent Spill-Sorb was then removed for disposal as fresh Spill-Sorb was added, thus allowing continuous cleanup operations.

Only Clean Water Now Spills into the Cape Town Foreshore

Here water, cleaned by being filtered and the hydrocarbons being totally encapsulated by the Spill-Sorb, runs over the harbour wall in Cape Town. The 4000 mm Spill-Sorb filled boom around the filters, as seen in the photograph, acts as a barrier in the event that any oil escaped while a tank was being recharged with Spill-Sorb.

The Result: For a nominal cost, the contracting engineers managed to clean the oil waste "on site" using Spill-Sorb as the encapsulating medium. An outstanding saving was being able to allow the now cleaned sea water to run back into the ocean. The oil-filled Spill-Sorb was economically removed to a land fill near by, with no threat of it ever leaching the encapsulated Bunker Oil.
