Introduction

Wastewater management is a critical aspect of industrial sustainability, particularly in high-tech manufacturing environments like Hyosung’s plant in Vietnam. With stringent environmental regulations and the need for efficient waste disposal systems, selecting the right pumping solutions becomes essential.

In this case study, we explore

how Ovell Pump provided the 2-inch PP (Plastic) Air-Operated Diaphragm Pump to efficiently transport wastewater at the Hyosung Vietnam Wastewater Treatment Facility.

We will discuss the challenges, solutions, and benefits of implementing this advanced pumping system.

‍

‍Background: Understanding the Need for Efficient Wastewater Handling

Hyosung's Vietnam plant generates substantial industrial wastewater, requiring effective treatment before disposal or reuse. Given the complex composition of wastewater from manufacturing processes—including chemicals, heavy metals, and particulates—reliable transport solutions are necessary to ensure efficient processing.

Traditionally, various pumping systems, such as centrifugal or peristaltic pumps, are used in industrial wastewater management. However, these systems often struggle with highly viscous or chemically aggressive fluids, leading to frequent maintenance issues and inefficiencies. Ovell Pump’s 2-inch PP Air-Operated Diaphragm Pump was selected to address these challenges due to its unique advantages.

Why Choose the 2-Inch PP Air-Operated Diaphragm Pump from Ovell Pump?

The choice of an air-operated diaphragm pump (AODD) over conventional pumps was driven by several key factors:

1. Material Compatibility
   • The pump's polypropylene (PP) housing ensures superior resistance to corrosive and abrasive wastewater components.
   • Unlike metal pumps, PP pumps do not react with acidic or alkaline substances, making them ideal for handling electronic industry effluents.
2. Self-Priming & Dry-Run Capability
   • The diaphragm pump can self-prime without external assistance.
   • It also runs without damage in dry conditions, preventing operational downtime due to accidental dry runs.
3. Air-Operated Mechanism
   • Since it operates on compressed air, there is no need for electricity, reducing risks in hazardous or wet environments.
   • Energy-efficient operation ensures lower costs in the long run.
4. Handling of Solids & Viscous Fluids
   • Many industrial wastewater streams contain suspended solids and sludge. The AODD pump handles solids up to a certain size without clogging, unlike centrifugal pumps.
   • It can transport viscous or shear-sensitive fluids without degradation.
5. Minimal Maintenance Requirements
   • With fewer moving parts compared to centrifugal or gear pumps, maintenance is significantly reduced.
   • Quick diaphragm replacement ensures minimal downtime.

3. Chemical Processing & Filtration:
   • The pump safely transports chemically treated wastewater between different filtration and processing units.
   • The PP material resists corrosion from acidic or alkaline chemicals used in neutralization.
4. Final Disposal & Reuse:
   • After treatment, clean water is either reused or safely discharged per environmental regulations.
   • The pump ensures consistent flow rates, crucial for maintaining efficiency.

Key Benefits of the 2-Inch PP Air-Operated Diaphragm Pump at Hyosung  Plant

The implementation of this pumping solution has provided multiple advantages, improving efficiency and reducing operational costs:

‍

1. Improved Pump Reliability

Traditional electric pumps suffered from frequent breakdowns due to exposure to corrosive chemicals. The AODD pump’s non-electric operation and corrosion-resistant PP material from Ovell Pump have significantly improved durability.

2. Enhanced Safety in Operation

Since AODD pumps operate on compressed air, the risk of electrical hazards in a wet environment is eliminated. This ensures compliance with safety standards for industrial wastewater management.

3. Lower Maintenance and Downtime

With minimal moving parts, the diaphragm pump requires less frequent maintenance. The ability to run dry without damage reduces downtime and prevents operational disruptions.

4. Cost Savings on Energy & Repairs

Electric pumps consume significant energy and require expensive repairs. The AODD pump from Ovell Pump eliminates electricity costs and lowers maintenance expenses, offering long-term savings.

5. Environmentally Sustainable Operation

Efficient wastewater management reduces the environmental footprint of Hyosung’s manufacturing operations. The pump contributes to regulatory compliance while supporting Hyosung ’s global sustainability goals.

Challenges and Solutions

While the AODD pump implementation was largely successful, a few challenges were encountered and resolved:

Challenge 1: Initial Installation Complexity

• Solution: A detailed site analysis was conducted, and custom piping adjustments were made to integrate the pump seamlessly.

Challenge 2: Compressed Air Supply Optimization

• Solution: Compressed air flow was adjusted to ensure optimal pump performance, balancing efficiency and cost.

Challenge 3: Flow Rate Calibration

• Solution: The pump’s air pressure was fine-tuned to maintain a steady flow rate, preventing fluctuations that could disrupt treatment processes.

Future Implications: Expanding Ovell Pump’s AODD Pump Use in Industrial Wastewater Management

Given the successful integration of Ovell Pump’s 2-inch PP AODD pump at Hyosung  Vietnam, similar applications can be considered for:

• Other electronics manufacturing facilities requiring high-efficiency wastewater transport.
• Chemical processing plants needing corrosion-resistant pumping solutions.
• Pharmaceutical production sites dealing with sensitive fluid handling.

The scalability and adaptability of Ovell Pump’s technology make it an excellent choice for industrial wastewater systems worldwide.
