We grind circuit boards and remove the metals on a shaking table. With waterThe waste silicone granules are washed off the table and collected in a large waste water trench.The waste water we use a spiral auger to remove the silicone waste but it is poor at removing all the particles so after a week we need to change the waterWe want to separate the silicone from the water and reuse the water that is cleaner than what we have now.
