Free Water Knock-Outs, Desalters and Dehydrators are just some of the applications in the oil industry where it is necessary to separate water and oil. The density differences between water and oil causes water to drop to the bottom of a separation tank, and oil to rise to the top.
HMA Geotechnical has supplied its Wisenmeshnet® wireless infrastructure monitoring system for one of the largest industrial projects in Eastern Indonesia. This is the first time that this system, intended mainly for mining and civil engineering, has been adapted successfully for such an application.
A tailings dam at an Australian mine had vibrating wire piezometers which were measuring the pore water pressure of the dam. Readings from the piezometers were being taken manually; however, the regularity of the readings was interrupted by harsh weather, site hazards, staffing and related factors.
