Case story

Gypsum Waste at a Titanium Dioxide Plant

Malaysia, Terengganu

The plant faced a problem with capacity and storage. Its filter presses were operating at maximum capacity and all sludge lagoons were full. The high capital expenditure  associated with adding additional filter press capacity and the low rate of return on investment motivated the plant to explore less costly alternatives of dewatering the sludge.

More than 100 units of Geotube® dewatering tubes with a circumference of 36.6m and lengths between 57m and 43.8m, stacked four levels high was installed over a year as part of an integrated plant waste capture program. A total of 180,000m3 of dry solids was captured within the tubes.
