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

Introduction

In modern wastewater treatment, sludge concentration and dewatering are critical processes that significantly impact operational efficiency and cost. Traditional methods often struggle with low efficiency, high energy consumption, and inconsistent results. As a leading Chinese manufacturer of ultrafiltration (UF) membranes, we provide high-quality, cost-effective solutions that optimize sludge treatment, ensuring faster processing, reduced waste volume, and improved water recovery.

Our self-produced ultrafiltration membranes are engineered to deliver superior performance, durability, and affordability, making them an ideal choice for sludge dewatering applications. With short lead times and competitive pricing, we help clients worldwide achieve better sludge management with minimal downtime.

The Challenge of Sludge Treatment

Sludge, a byproduct of wastewater treatment, contains high water content (up to 95-99%), making it bulky and expensive to handle. Efficient sludge thickening and dewatering are necessary to:

1. Reduce disposal costs (less volume = lower transportation and landfill fees)

2. Improve incineration efficiency (higher solid content burns better)

3. Recover reusable water (for recycling or safe discharge)

4. Minimize environmental impact (less sludge waste = lower pollution risk)

Conventional methods like centrifugation, belt filter presses, and sedimentation often fall short in terms of energy efficiency, maintenance costs, and final dryness levels. This is where ultrafiltration membranes offer a game-changing solution.

Why Our Ultrafiltration Membranes Excel in Sludge Dewatering

1. Precise Pore Size for Optimal Solid-Liquid Separation

Our UF membranes feature a controlled pore size (0.01–0.1 microns), effectively separating fine solids, bacteria, and colloidal particles from water. This ensures:

Higher sludge concentration (reducing water content before mechanical dewatering)

Better filtrate quality (clear permeate for reuse or safe discharge)

Lower polymer consumption (reduced need for chemical conditioning)

2. High Mechanical & Chemical Resistance

Strong, durable materials (PVDF, PES) resist fouling and frequent cleaning.

Tolerant to harsh chemicals (acids, alkalis, oxidants) for long-term use.

Stable performance under high pressure, ensuring consistent dewatering efficiency.

3. Energy-Efficient Operation

Compared to traditional dewatering methods, UF membranes consume less energy while achieving higher solid content (up to 20-30% DS). This reduces operational costs significantly.

4. Compact & Modular Design

Space-saving compared to large settling tanks or centrifuges.

Easy integration into existing sludge treatment systems.

Scalable solutions for small to large wastewater plants

Q&A

Q: Can UF systems operate continuously?

A: Yes, with automated backwash cycles every 30-90 minutes.

Q: What's the typical cross-flow velocity?

A: 0.5-3 m/s to maintain proper scouring of membrane surfaces.

Q: How is molecular weight cutoff (MWCO) determined?

A: By testing rejection rates of standard molecules like PEG or dextrans.
