Stone Factory Solutions: How to Master Wastewater Recycling
石材厂解决方案：如何掌握污水循环利用

For granite and marble processing factories, water is as important as the diamond blade. Bridge saws, CNC machines, and polishing lines consume massive amounts of water to keep tools cool and suppress dust.
对于花岗岩和大理石加工厂来说，水和金刚石锯片一样重要。桥切机、CNC 数控机床和抛光线消耗大量的水来保持工具冷却并抑制粉尘。

However, the resulting wastewater is full of stone powder (stone sludge). If not treated properly, this abrasive sludge can clog your pipes and, worse, scratch the polished surface of your expensive stone slabs.
然而，产生的废水中充满了石粉（石材污泥）。如果不妥善处理，这种具有研磨性的污泥会堵塞您的管道，更糟糕的是，会划伤您昂贵石板的抛光表面。

Foshan Porvoo offers a dedicated solution for the stone industry to achieve Zero Liquid Discharge (ZLD).
佛山波尔沃为石材行业提供零排放 (ZLD) 的专用解决方案。

1. The Danger of “Dirty Water” in Stone Processing
石材加工中“脏水”的危害

Many factories try to reuse water using simple settling pits. But fine stone particles often remain suspended. Recirculating this “dirty water” causes:
许多工厂尝试使用简单的沉淀池回用水。但细小的石材颗粒通常仍然悬浮。循环使用这种“脏水”会导致：

• Shortened Tool Life: Abrasive particles wear out diamond segments faster.
  缩短工具寿命：研磨性颗粒会加速金刚石刀头的磨损。
• Surface Defects: Tiny scratches on marble or quartz surfaces, leading to rejection.
  表面缺陷：大理石或石英石表面的微小划痕，导致产品报废。
• Pump Failures: Sludge buildup burns out water pumps.
  水泵故障：污泥堆积会导致水泵烧毁。

2. Porvoo’s Solution: High-Efficiency Sewage Tower
波尔沃的解决方案：高效污水塔

Our Deep Cone Thickener (Sewage Tower) is the industry standard for separating stone powder. Unlike flat-bottom tanks, the vertical cone design uses gravity and a specific flocculant mix to settle stone fines instantly.
我们的深锥浓缩罐（污水塔）是分离石粉的行业标准。与平底罐不同，垂直锥体设计利用重力和特定的絮凝剂混合物瞬间沉降石材细粉。

• Crystal Clear Water: The overflow water is clean enough to be reused directly on your polishing heads.
  水晶般清澈的水：溢流出的水足够干净，可直接回用于您的抛光磨头。
• Small Footprint: A vertical tower saves valuable factory floor space compared to large horizontal ponds.
  占地小：与大型水平池相比，垂直塔节省了宝贵的工厂地面空间。

3. Handling the Sludge: Filter Press for Stone Mud
处理污泥：用于石材泥浆的压滤机

Granite and marble sludge is heavy and abrasive. You need a robust machine to handle it. Our Chamber Filter Press creates dry, stackable cakes that are easy to dispose of.
花岗岩和大理石污泥既重又有研磨性。您需要一台坚固的机器来处理它。我们的厢式压滤机能产生干燥、可堆叠的滤饼，易于处理。

Key Feature: Our filter presses feature 304 Stainless Steel cladding on the main beam to resist corrosion and wear from stone slurry.
关键特性：我们的压滤机主梁采用 304 不锈钢包覆，以抵抗石材泥浆的腐蚀和磨损。
