Wastewater Reuse System – A Sustainable Solution for Cost Savings and Circular Water Management

As clean water costs and wastewater discharge fees continue to rise, investing in a Wastewater Reuse System has become a strategic solution for modern industries. Instead of discharging all treated wastewater, businesses can recover and reuse this valuable resource for production processes, cooling systems, equipment washing, factory cleaning, irrigation, and other industrial applications.

VIET WATER JOINT STOCK COMPANY (VIET WATER JSC) provides complete wastewater reuse solutions, including design, engineering, construction, commissioning, operation support, and technology transfer. Our Smart & Green technologies help businesses reduce operational costs, conserve water resources, improve ESG performance, and support Net Zero commitments.

What Is a Wastewater Reuse System?

A Wastewater Reuse System is an advanced water treatment solution that further purifies treated wastewater to produce high-quality reclaimed water suitable for industrial and technical reuse applications.

Instead of being discharged into the environment, treated wastewater undergoes additional polishing processes using advanced technologies such as:

• Ultrafiltration (UF)

• Membrane Bioreactor (MBR)

• Reverse Osmosis (RO)

• Activated Carbon Filtration

• UV Disinfection

• Ozone Treatment

• Ion Exchange

• Demineralization Technologies

The result is a reliable and sustainable alternative water source for industrial operations.

Why Should Businesses Reuse Wastewater?

Today, many industries discharge 100% of treated wastewater while continuing to purchase fresh water at increasing prices.

This creates significant operational expenses related to:

• Freshwater consumption

• Water treatment costs

• Wastewater discharge fees

• Overall plant operating expenses (OPEX)

Wastewater reuse transforms wastewater from a disposal burden into a valuable resource, supporting circular economy principles and sustainable business growth.

Key Benefits of Wastewater Reuse Systems

Reduce Freshwater Costs by 50–60%

Reclaimed water can be reused for:

• Cooling towers

• Boiler feed systems

• Equipment cleaning

• Factory sanitation

• Irrigation

• Various industrial processes

This significantly reduces dependence on municipal or groundwater supplies.

Reduce Wastewater Discharge Costs by 50–60%

By recycling treated wastewater, companies can significantly reduce wastewater discharge volumes and associated treatment costs.

Generate Long-Term Positive Cash Flow

For medium-sized manufacturing facilities, wastewater reuse systems can generate substantial annual savings through:

• Lower water purchase costs

• Reduced wastewater fees

• Optimized operating expenses

Fast Return on Investment (ROI)

Depending on project size and water consumption patterns, the typical payback period ranges from:

3–5 years

After that, businesses continue to benefit from long-term operational savings.

• Odor removal systems

These technologies remove remaining impurities and contaminants.

Disinfection

Final disinfection can be achieved through:

• UV sterilization

• Ozone treatment

• Chlorination

to ensure microbiological safety.

Storage and Reuse

The reclaimed water is stored in dedicated tanks and redistributed for various industrial applications.

Reclaimed Water Quality Standards

Depending on the intended application, the treated water can be designed to meet:

• QCVN 02:2009/BYT

• QCVN 01-1:2018/BYT

• Client-specific industrial water standards

• Technical water supply requirements

• Cooling water standards
