Industrial wastewater treatment has advanced from basic chemical handling to modern nanofiltration, integrating advanced physical, chemical, and biological processes for safer, more efficient pollutant removal.

The stone processing industry produces high-volume wastewater with suspended solids and chemicals; membrane filtration offers effective treatment for fine stone particles.

Nanofiltration uses membranes with 1–10 nanometer pores to selectively remove divalent ions, small organic molecules, and total dissolved solids from water.

Nanofiltration uses 1–10 nm membrane pores to selectively separate molecules by size and charge, enabling partial demineralization with high flow rates for water treatment and industrial processes.

Ceramic and stone processing generates 45,000 liters of wastewater daily, containing 500-5000 mg/L suspended solids, fine particles, glazing compounds, and trace metals.

Grit removal system for industrial wastewater from ceramic/stone processing uses abrasion-resistant materials to separate 95% of 75 μm grit, preventing equipment wear.

Grit removal system for industrial wastewater from ceramic/stone processing handles abrasive particles ≥0.2 mm, with 98% efficiency, corrosion-resistant materials, and low organics content.

Automated wastewater treatment stone fabrication systems use filter presses and hydro-cyclones to treat up to 396 GPM, achieving water clarity below 10 microns for reuse and reduced labor costs[1][4][5].

Compact silo systems provide high-efficiency solid-liquid separation with minimal footprint, while filter press wastewater treatment achieves higher cake dryness (up to 99% solids) and is ideal for applications needing maximum sludge volume reduction and consistent performance.

Ceramic wastewater filtration performance metrics include COD/BOD removal rates, membrane pore size (0.05–0.2 μm), flux (10–1000 L/h·m²·bar), and material stability under high temperature, pH, and chemical exposure.
