AL-Haffer company constructs salt dike by the cutter suction dredger(CSD).The World Of Dredging has many purposes, including maintenance, land reclamation and used for the mining of minerals. In Jordan, Arab Potash Company (APC) is harvesting potassium-contained salts (potash) in the Dead Sea with cutter suction dredgers. Potassium is extracted from the potash and used as a fertilizer in agriculture.especially the salinity of the dead sea it is 9.6 times more salty than the ocean)
How does it work? Water from the Dead Sea is pumped into the APC ponds for a few months each year. It flows slowly south through all ponds, and the salt settles in the first few to create extremely hard layers containing salt mushrooms. The other minerals do not settle, but flow to the southern ponds. After a few years, the northern ponds are silted up with salt to the extent that they block the water flow.
The salt content in the southern ponds decreases and the concentration of the potash increases because of the previously mentioned salt settling and water evaporating. This is exactly the purpose of this process. Finally, the potash content reaches a certain concentration level so that it also settles and is ready for harvesting.
The dredging of the potash in the southern ponds is a continuous process, but the APC harvesters are not able to reach the corners and sides of the ponds. The negative effects of this are that the ponds become smaller and the production decreases by 10%. This is why APC utilize the cutter suction dredger which is able to dredge the corners and sides of the ponds, and pump the potash directly to the harvesters. The potash is much softer than the salt. To recover the northern ponds, another dredges able to dredge and pump the salt to a depth of six meters. At this stage , AL-Haffer company creates salt dike according to engineering standers and specialized engineering staff to carry out the work
