PORVOO Stone Wastewater Recycling System Installed in U.S. Stone Fabrication Plant

PORVOO recently completed the installation of a stone wastewater treatment system at a stone fabrication plant in the United States. The system was designed to handle the high-solid wastewater generated during granite and quartz slab cutting and polishing operations.

PORVOO近日在美國一家石材加工廠完成石材廢水處理系統的安裝。該系統專為解決花崗岩與石英板切割拋光過程中產生的高濃度廢水問題而設計。

The compact tower-type design combines sedimentation, thickening, and filter pressing in one unit. Using a vertical purification tower, the system reduces the need for traditional sedimentation ponds and significantly saves space.

該系統採用緊湊型塔式結構，將沉澱、濃縮與壓濾集成於一體。通過垂直式淨水塔處理流程，大幅降低對傳統沉澱池的依賴，節省廠區空間。

The customer reported that over 90% of process water was successfully recycled back into the cutting machines. Filter cakes with moisture content under 30% were easy to transport and dispose of.

客戶反映系統可將90%以上的加工用水回收再用於切割設備，同時排出的泥餅含水率低於30%，便於搬運與堆放處理。

The system operates fully automatically with minimal human intervention, making it ideal for U.S. factories seeking efficient and eco-friendly solutions.

系統全自動運行，人工干預極少，特別適合美國工廠對高效率與環保的雙重需求。
