FILTRAPRESS
Product Features
Semiconductor wastewater—especially from backgrinding and CMP (Chemical Mechanical Polishing)—contains ultra-fine silica, alumina slurry, metal particles, polymers, and abrasive solids that many conventional filters fail to capture.
[FILTRAPRESS] solves these challenges with precise solid–liquid separation designed specifically for high-precision manufacturing.
PRODUCT FEATURES
- Maximum Capture of Ultra-Fine Particles
- Designed for 0.2–5 μm CMP abrasives
- Maintains consistent clarity even at high solid loading
- Superior cake formation for easier disposal
- High Filtration Efficiency for Backgrind Slurry
- Handles silicon fines, grinding sludge, and suspended solids
- Prevents clogging with optimized chamber design
- Reduces turbidity to <10 NTU
- Reusable Filtrate Quality
- Turbidity consistently < 5–10 NTU
- Suitable for reuse in:
- Backgrind rinse water
- CMP pad washing
- Utility & pre-treatment systems
Why water important?
Water is a limited, shared resource essential for life, healthy ecosystems, and the global economy.
Yet, rising demand, climate change, and pollution are straining water supplies worldwide, posing challenges for businesses and communities alike. This situation not only brings risks but also new opportunities for investors newspaper.

CMP Wastewater Testing & Analysis


Backgrinding Wastewater Before vs After FiltraPress During Operation




Summary CMP Wastewater Before & After FiltraPress Testing Results
CMP Wastewater | Additive* | pH | Conductivity (μs/cm) | Turbidity (NTU) | Filtrate Clarity |
|---|---|---|---|---|---|
Raw Waste | - | 9.32 | 251.6 | 321 | Cloudy |
After FiltraPress | YES | 9.32 | 270.6 | 7.07 | Clear Supernatant |
Conclusion – Driving ESG Compliance and Sustainable Business Performance
Implementing an advanced filtration system effectively reduces hydraulic and contaminant loading on the wastewater treatment process. This results in lower chemical dosing requirements, reduced sludge generation, and overall optimization of operational expenditure (OPEX).
The clarified filtrate can be reused directly or further polished through UF and RO systems to maximize water recovery efficiency. In addition, the recovered silica-based sludge can be repurposed, enabling circular-economy resource utilization.
Collectively, these improvements strengthen regulatory compliance, enhance system performance, and support the achievement of ESG targets—driving long-term, sustainable, and commercially resilient operations.
