DuPont IntegraPac™ IP-77 Ultrafiltration Membrane for Electronic Grade Ultrapure Water Equivalent

Introduction

In the food processing industry, wastewater management is a critical challenge, particularly for sectors like potato processing and brewing, where effluents contain valuable byproducts such as starch and enzymes. Traditional treatment methods often fail to recover these resources efficiently, leading to economic waste and environmental concerns. As a leading Chinese manufacturer of high-performance ultrafiltration (UF) membranes, we offer cost-effective, rapid-turnaround solutions to help food processors reclaim valuable materials while meeting stringent discharge standards.

The Challenge: Starch & Enzyme-Laden Wastewater

Food processing wastewater—especially from potato, corn, and brewing operations—contains low concentrations of starch, proteins, and enzymes. Discharging this effluent untreated can lead to:

1. Resource waste: Recoverable starch/enzymes are lost.

2. High COD/BOD levels: Untreated wastewater pollutes water bodies.

3. Regulatory non-compliance: Many regions impose strict limits on organic discharge.

Conventional methods like sedimentation or chemical coagulation are inefficient for recovering fine particles or bioactive enzymes. This is where ultrafiltration membranes excel.

Our Solution: High-Performance UF Membranes for Food Wastewater

Our self-manufactured ultrafiltration membranes are engineered to:

1. Recover Starch & Enzymes

Pore size precision (0.01–0.1 µm): Captures starch molecules and enzymes while allowing water and salts to pass.

High selectivity: Separates target substances without chemical additives, preserving their functionality for reuse.

2. Produce Permeate Suitable for Discharge/Reuse

Reduces COD by 70–90%, ensuring compliance with environmental regulations.

Permeate can be recycled for non-potable uses (e.g., cleaning, irrigation).

3. Operational Advantages

Cost-efficient: Our in-house production cuts costs, offering you competitive pricing.

Fast delivery: Agile manufacturing ensures short lead times, even for large orders.

Durable & Low-maintenance: Hydrophilic PVDF/PES materials resist fouling, reducing downtime.

Case Study: Potato Processing Wastewater

A client in China’s potato starch industry faced high wastewater treatment costs and starch loss. After installing our UF system:

1. Starch recovery rate: Increased to >85%, boosting revenue.

2. Effluent COD: Reduced from 2,500 mg/L to <300 mg/L.

3. Payback period: <12 months due to resource savings.
