Al Asriyah Marble Company LLC Oman chooses F&B’s technology and quality


AL ASRIYAH MARBLE COMPANY LLC, one of the most important Companies in the world for the processing of marble, has inaugurated a new plant in Oman, with the installation of several up-to-date machines for the processing of stone materials. As for the water treatment plant and sludge dewatering, AL ASRIYAH MARBLE COMPANY LLC., has relied on FRACCAROLI E BALZAN SpA, which, based on decades of experience, has designed, manufactured and installed a system that represents the state of the art in the waste water treatment sector.
The decantation circuit is made up of one decanter mod. FB/6000 V-WD (diameter 6 m), a clean water storage tank for the decanted water and a recycling unit for sending back the clean water to the machines.
Inside the waste water pit, a second waste water pump is installed to be kept as spare and the flocculant station is equipped with two flocculant dosing pumps, working alternatively. In this way, the system can work continuously without any interruption.
The flocculant station is fully automatic, for better handling the flocculant consumption.
Concerning the mud dehydration, the liquid slurry discharged from the decanter is collected into a mud tank and, through a centrifugal pump, goes to the filterpress FB/1000-15 EXP 20. The filterpress is expandable up to 20 plates, so, in case more processing machines are going to be installed in the future, the filterpress will be able to cope with the higher production rate.
Moreover, a special device for the mud separation has been installed: the Customer can choose in which of the two containers, located under the filterpress, to collect the dehydrated mud.
The whole plant is fully automatic and all functions and operating parameters are controlled by a PLC.
To sum up, an innovative and pioneering plant, a reference of absolute prestige in addition to thousands more installed all around the world in over forty-five years of activity.
