TenCate Geosynthetics Asia secured an order at Huntsman Tioxide in Teluk Kalong (Malaysia) for the supply of 105 TenCate Geotube systems, according to a press release from the company.
These systems are intended for use in Malaysia as an environmentally friendly solution for the dewatering and storage of calcium sulfate. The containers will be produced by TenCate Industrial Zhuhai (China) and supplied through Ashland, a company involved in, among other endeavors, the field of wastewater treatment. Deliveries for this project commenced in October and will continue into next summer, the company said.
The production of titanium dioxide generates large quantities of calcium sulfate, which must be processed and stored in an environmentally suitable manner. Before this waste product can be stored, it first has to be dewatered. Polymers are added to aid in the dewatering process and these are supplied by Ashland, the press release said. The polymers accelerate the process of dewatering by bonding the solid matter. The TenCate Geotube acts as a filtration and storage system.
According to the press release, the system supplied to Huntsman is one of the largest Asian projects to date. Each TenCate Geotube for this project has a diameter of 36.6m (40 yards). Laid end to end, the length of all these geocontainers totals 5.5km (3.4mi).
