Sawing processes for manufacturing silicon bricks and wafers are indispensable in the semiconductor industry. Slurry is the cutting fluid used together with diamond wire saws to cut silicon blocks into paper-thin wafers. Slurry is also produced in the production of the bricks. This fluid consists of silicon carbide dissolved in oil and glycol. EPC constructs the slurry recycling plants that separate the constituents of the fluid, and prepare them for recycling back into the manufacturing process.
Slurry supply systems from EPC are safe, efficient and environmentally friendly. We offer special, highly accurate mixing and supply systems. We also construct recycling plants that filter the water/slurry mixture used in the production processes to recover the valuable constituents. This recovery process not only minimizes storage and transport costs but also reduces the costs of preparing ultrapure water and disposing of waste water.
