WASOL A Trusted Brand in Wastewater Treatment System Design & Construction

Amid increasingly stringent environmental regulations and the growing emphasis on sustainable development as a core part of corporate strategies, wastewater treatment systems are no longer just a legal requirement — they have become an essential component of modern industrial operations.

With nearly 15 years of experience in implementing wastewater treatment systems across Vietnam, WASOL has affirmed its position as one of the most trusted and professional design-and-build contractors in the field, earning the confidence of many businesses nationwide.

WHAT IS A WASTEWATER TREATMENT SYSTEM?

A wastewater treatment system is a combination of technologies and engineering processes designed to remove pollutants from wastewater before it is discharged into the environment or reused for other purposes. It plays a crucial role in protecting water resources, ensuring public health, and supporting the sustainable development of industrial and domestic activities.

TYPES OF WASTEWATER TREATMENT SYSTEMS

1. Domestic Wastewater Treatment Systems

• Applications: Residential areas, high-rise apartment buildings, hotels, restaurants, shopping malls, etc.

• Wastewater characteristics: Primarily contains biodegradable organic matter, suspended solids, household grease, and bacteria.

• Common technologies: Septic tanks, activated sludge, membrane bioreactors (MBR), etc.

2. Industrial Wastewater Treatment Systems

• Applications: Manufacturing plants, industrial zones, multi-sector industrial clusters.

• Wastewater characteristics: Complex composition, may contain heavy metals, non-biodegradable organic compounds, toxic chemicals, and suspended solids.

• Common technologies: Coagulation – flocculation – sedimentation, Compasedi integrated settling tank, advanced flotation (OpFlo), advanced oxidation processes (AOP), RO membrane filtration, biological treatment (Aerotank/MBBR/SBR), Advanced Clarifier, Advanced Flotation…

3. Steel and Galvanizing Industry Wastewater Treatment

• Applications: Steel rolling mills, galvanizing plants, cold-rolled steel production, metal fabrication workshops.

• Wastewater characteristics: Generated from surface washing, degreasing, pickling, electroplating, and cooling; often contains heavy metals, acids, alkalis, surfactants, industrial grease, TSS, and insoluble solids.

• Common technologies: Oil separation, coagulation – flocculation, Compasedi, Advanced Flotation…

4. Medical Wastewater Treatment Systems

• Applications: Hospitals, general clinics, medical centers, testing labs, research institutes…

• Wastewater characteristics: Contains pathogens (bacteria, viruses), pharmaceutical residues, radioactive substances, chemical reagents, and other hazardous components.

• Common technologies: Disinfection using chlorine, ozone, or UV; biological treatment combined with RO filtration; closed-loop systems to ensure absolute biosafety.

5. Seafood Processing Wastewater Treatment Systems

• Applications: Seafood processing plants, cold storage facilities, aquaculture zones, shrimp ponds, fish farms…

• Wastewater characteristics: High levels of organic matter, protein, grease; easily biodegradable; emits odors and contains pathogenic bacteria.

• Common technologies: Anaerobic treatment (UASB), activated sludge or MBBR biological treatment, dissolved air flotation (DAF)…

6. Other Specialized Wastewater Treatment Systems

In addition to the main sectors listed above, WASOL also provides customized wastewater treatment solutions for:

• Livestock farming

• Textile and dyeing, garment industry

• Chemical, electroplating, electronics industries

• Food and beverage processing

CHOOSING AN EFFECTIVE EPC CONTRACTOR FOR WASTEWATER TREATMENT SYSTEMS

To ensure a cost-effective investment, businesses should carefully consider the following criteria when selecting a wastewater treatment system:

✅ Compatible with wastewater characteristics

Each industry produces wastewater with specific properties. For example, food processing wastewater has high COD and BOD levels; electroplating and electronics industries discharge water with heavy metals; textile and dyeing wastewater contains dyes and hard-to-degrade chemicals. Selecting the right technology tailored to these characteristics will optimize both treatment efficiency and operational costs.

✅ Meets discharge standards

The system must ensure that treated water complies with environmental regulations such as QCVN 40:2011/BTNMT or specific standards of local authorities and industrial zones.

✅ Easy operation and cost-effective

The system should be designed for stable operation with low energy and chemical consumption, and be easy to maintain to minimize long-term costs.

✅ Scalability and flexibility

The system should allow for future capacity expansion or technology upgrades as production scales up.

✅ Reliable and experienced contractor

A professional design-build contractor will ensure standard compliance from surveying, technology selection, construction to commissioning – minimizing technical risks and post-installation issues.
