refurbishment desander Aletsch
Installed in 1963, the desander has been used successfully since then.
Equipped with two 50 m long basins, each consisting of two 25 m units, everything was working perfectly well, but the mechanical parts showed wear and tear (after 40 years of use!) which caused the system to leak and thus to lose efficiency.
Thanks to the method developed by SST for BIERI desanders, a complete overhaul of the mechanical part was done, without touching the civil engineering structure.
After the overhaul, the water leaks were eliminated, and the desander has now the same efficiency as when it was put into service.

wet commissioning desander Ulu Jelai Malaysia
Apart from the seven-kilometre-long power waterway, the project includes two complex weirs and two water transfer tunnels, which divert water to the main dam from the neighbouring Lemoi and Telom River catchments. The two water transfer tunnels contribute about 30% to the combined flow of water available for power generation. Tunnelling for the main power waterway and the two water transfer tunnels was challenging and required the team to apply creative problem-solving skills.
The desander delivered and installed by SST had, as of September 2015, only been used in test mode and left as is.
After the tunnel was completely drilled, and without any additional operations of maintenance, the desander was successfully commissioned in real conditions.
This proves the relevance of the choice of the SST desander, which can now operate without any additional intervention after almost five years of immobilization in a difficult environment.
Because of the pandemic situation, wet commissioning has beeen performed with sucess by our partner MPA Fluid Power (M) Bhd
