Asahi Kasei Microza UNA-620AB Ultrafiltration Membrane for Electronic Grade Ultrapure Water Equivalent

Introduction

Effective sludge treatment is a cornerstone of sustainable wastewater management. As industries and municipalities face stricter environmental regulations and rising disposal costs, the demand for efficient, cost-saving dewatering solutions has never been higher. Our cutting-edge ultrafiltration (UF) membranes, manufactured in-house, provide a breakthrough in sludge concentration and dewatering, delivering unmatched performance, reliability, and affordability.

Unlike conventional methods that rely on energy-intensive processes, our UF membrane systems enhance sludge treatment by maximizing solid recovery, minimizing water content, and reducing operational expenses. With rapid production capabilities and flexible customization, we empower clients to optimize their sludge handling with minimal downtime.

The Growing Need for Efficient Sludge Dewatering

Sludge, a residual product from wastewater treatment, poses significant challenges due to its high moisture content (often exceeding 95%). Traditional dewatering techniques, such as centrifuges, filter presses, and drying beds, often struggle with:

1. High energy consumption – Increasing operational costs

2. Excessive chemical usage – Adding expenses and environmental concerns

3. Inconsistent results – Variable dryness levels leading to higher disposal fees

4. Large footprint requirements – Taking up valuable plant space

Our ultrafiltration membrane technology addresses these issues by enhancing solid-liquid separation efficiency, ensuring higher dryness levels, lower energy use, and a more compact system design.

Key Advantages of Our Ultrafiltration Membranes in Sludge Treatment

1. Superior Filtration Precision

Our UF membranes feature optimized pore structures (0.01–0.1 µm), effectively capturing fine particles, colloids, and microorganisms while allowing clean water to pass through. This results in:

Thicker sludge consistency (reducing volume before mechanical dewatering)

Higher-quality filtrate (suitable for reuse or compliant discharge)

Reduced polymer demand (lower chemical costs)

2. Exceptional Durability & Fouling Resistance

Robust membrane materials (PVDF, PES) withstand harsh operating conditions.

Anti-fouling surface properties minimize clogging and extend service life.

Compatible with aggressive cleaning agents, ensuring long-term performance stability.

3. Energy & Cost Savings

Compared to traditional dewatering equipment, our UF systems operate with lower power consumption, significantly cutting energy bills. The higher solid retention also means less sludge volume for disposal, translating to major cost reductions in transportation and landfill fees.

4. Modular & Scalable Design

Compact footprint – Ideal for facilities with space constraints.

Easy retrofitting – Can be integrated into existing treatment lines.

Expandable capacity – Suitable for both small plants and large-scale industrial applications.
