Top 10 Wastewater treatment plant Suppliers, Manufacturers, Wholesalers and Traders in Viet Nam

Vietnam's industrial landscape is booming, with factories, manufacturing hubs, and recycling facilities sprouting up from the north to the south. As this growth accelerates, so does the need for responsible wastewater management—after all, protecting the country's rivers, lakes, and coastal waters is not just a legal requirement but a moral one. Behind every compliant factory or efficient recycling plant is a reliable wastewater treatment supplier, armed with the right tools to turn industrial runoff into clean, reusable water. Today, we're shining a light on 10 standout suppliers in Vietnam that are making waves in this critical field, each bringing unique strengths, innovative equipment, and a commitment to sustainability.

Why Choosing the Right Supplier Matters

The best suppliers understand this, offering tailored equipment and expertise to match each industry's challenges. From effluent treatment machines that remove harmful contaminants to water process equipment that optimizes resource use, these suppliers are the unsung heroes ensuring Vietnam's industrial growth doesn't come at the cost of its environment. Let's dive into the top 10.

Top 10 Wastewater Treatment Plant Suppliers in Vietnam: At a Glance

Spotlight on the Top Suppliers

1. GreenTech Solutions (Hanoi)

Tucked away in Hanoi's bustling Dong Anh district, GreenTech Solutions has been a quiet force in northern Vietnam's wastewater treatment scene since 2005. What started as a family-run business fixing pumps and filters has evolved into a full-service provider, known for its ability to think outside the box. Walk into their showroom, and you'll find rows of effluent treatment machine equipment—some sleek and modern, others rugged and built for the gritty reality of a factory floor. "We don't just sell machines; we solve problems," says founder Minh Tran. "A textile factory in Bac Ninh needed to remove 95% of dye from its water, and standard equipment wasn't cutting it. So we modified our effluent treatment system with a specialized adsorption filter, and now they're not only compliant but saving on water costs by reusing 60% of treated water."

GreenTech's water process equipment is another highlight. Their latest models come with touchscreen controls and IoT connectivity, letting plant managers monitor pH levels, turbidity, and chemical dosages from their phones. "It's not just about technology—it's about making life easier for our clients," Minh adds. With a client list spanning food processing, electronics, and automotive industries, GreenTech has earned a reputation for reliability, often getting referrals from satisfied customers in Thai Nguyen and Hai Duong provinces.

2. EcoWater Systems (Ho Chi Minh City)

If GreenTech is the north's problem-solver, EcoWater Systems is the south's innovator. Based in Ho Chi Minh City's industrial Thu Duc district, this supplier has made a name for itself by asking: Why treat water and air separately? Their answer is a lineup of integrated systems that pair air pollution control system equipment with water process equipment, creating a one-stop shop for factories looking to reduce their environmental footprint. "A battery recycling plant doesn't just have wastewater—it has fumes from melting metals," explains technical director Lam Vu. "Our air scrubbers work in tandem with effluent treatment machines, so when the plant processes lead-acid batteries, both the water and air are cleaned before release."

EcoWater's commitment to compliance is evident in every product. All their equipment, from compact air pollution control units to large-scale water process systems, carries ISO 14001 certification, a must for clients navigating Vietnam's updated environmental laws. What clients love most, though, is their transparency. "We walk them through every step—design, installation, training—so they understand exactly how their system works," Lam says. It's this hands-on approach that has made them a favorite among multinationals setting up shop in Binh Duong and Dong Nai provinces.

3. VietWaste Treatment (Da Nang)

Da Nang's VietWaste Treatment isn't afraid of heavy metal—literally. Specializing in wastewater from metals, mining, and recycling industries, this supplier has built its reputation on handling the tough stuff: water laced with lead, mercury, or industrial solvents. Their bread and butter? Effluent treatment machine equipment designed to tackle high concentrations of contaminants, paired with wet process equipment that uses minimal chemicals. "A zinc mine in Quang Nam once came to us with water so polluted, fish wouldn't swim near it," recalls sales manager Hoa Pham. "We installed a three-stage effluent treatment system—coagulation, sedimentation, and reverse osmosis—and within three months, their discharge met national standards. Now, they even use the treated water to wash trucks."

VietWaste's team of chemical engineers is their secret weapon. They spend weeks analyzing a client's wastewater before recommending a solution, ensuring the equipment is tailored to specific contaminants. "No two mines or metal plants are the same," Hoa notes. "What works for a copper refinery might not work for a steel mill, so we never take a cookie-cutter approach." With clients as far north as Vinh and as far south as Nha Trang, VietWaste has become the go-to for industries that others might shy away from.

4. CleanFlow Engineering (Haiphong)

Not every business in Vietnam is a sprawling factory—and CleanFlow Engineering knows that. Based in Haiphong, this supplier caters to small and medium enterprises (SMEs) that need effective wastewater treatment without breaking the bank. Their lineup includes compact water process equipment and dry process equipment that's easy to install, energy-efficient, and designed for businesses with limited space. "A family-run furniture factory in Hai Phong's Dinh Vu Industrial Zone came to us with a problem: they couldn't afford a large treatment plant, but they needed to stop dumping paint-contaminated water into the nearby river," says founder Khanh Le. "We installed a small dry process system that uses filtration and evaporation—no chemicals, low energy use—and now they're compliant for a fraction of the cost of a traditional setup."

CleanFlow's focus on affordability doesn't mean skimping on quality. Their dry process equipment, for example, uses advanced membrane filters that last up to five years, reducing maintenance costs. They also offer flexible payment plans, a boon for SMEs still finding their footing. "We believe every business, no matter how small, should have access to clean water solutions," Khanh adds. It's this mission that has made CleanFlow a staple in Haiphong's SME community, with clients in seafood processing, garment manufacturing, and small-scale recycling.

5. Sustainable Solutions Vietnam (Can Tho)

The Mekong Delta is Vietnam's agricultural heartland—and Sustainable Solutions Vietnam is its wastewater guardian. Based in Can Tho, this supplier specializes in treating the unique runoff from rice mills, fish processing plants, and fruit canneries: water loaded with organic matter, pesticides, and high levels of BOD (biological oxygen demand). Their secret? A blend of effluent treatment machine equipment and air pollution control system equipment that targets both water and the methane-rich odors often associated with agricultural waste. "A fish sauce factory in Phu Quoc was losing customers because of the smell," says operations manager Linh Nguyen. "We installed an anaerobic digester to treat the wastewater and a biofilter to capture odors. Now, they've expanded production and even sell the biogas from the digester as a byproduct!"

Sustainable Solutions prides itself on working with local communities. They often partner with farmer cooperatives in Tra Vinh and Soc Trang provinces, offering training sessions on how to maintain their equipment and reduce water use. "Many of our clients are first-generation entrepreneurs who've never dealt with wastewater systems before," Linh explains. "We don't just sell them a machine—we teach them to own it." It's this community-focused approach that has made them a trusted name in the delta, where environmental protection and livelihoods go hand in hand.

6. AquaTech Industries (Nha Trang)

Nha Trang might be known for its beaches, but inland, AquaTech Industries is making a splash in recycling plant wastewater treatment. This supplier has carved out a niche serving the growing battery and plastic recycling sectors, where water is often contaminated with heavy metals, acids, and microplastics. Their star products include water process equipment and compact granulator with dry separator equipment, which work together to separate solids from liquids, making treatment more efficient. "A lithium-ion battery recycler in Khanh Hoa needed to recover cobalt and lithium from their wastewater," says technical lead Tuan Pham. "Our granulator dries and separates the solids, which are then sent for metal recovery, while the liquid goes through our effluent treatment machine. It's a closed-loop system that reduces waste and boosts profits."

AquaTech's team stays ahead of the curve by collaborating with researchers at Nha Trang University, testing new filtration materials and treatment methods. "Recycling technology evolves fast, so our equipment has to keep up," Tuan notes. Clients praise their responsiveness, with many highlighting how AquaTech's after-sales support—including spare parts delivery within 48 hours—keeps their plants running smoothly.

7. EnviroPro Supplies (Bien Hoa)

Bien Hoa's EnviroPro Supplies is all about tackling the "tough stuff"—wastewater with high solids content, like sludge from food processing or pulp from paper mills. Their lineup includes heavy-duty effluent treatment machine equipment and hydraulic press machines equipment that can squeeze water out of thick, viscous waste, turning it into manageable solids for disposal or reuse. "A paper mill in Dong Nai was spending a fortune on hauling away sludge," says sales director Phuong Do. "We installed a hydraulic press that reduces sludge volume by 70%, cutting their disposal costs in half. Now, they even sell the dried sludge as fertilizer to local farmers!"

EnviroPro's equipment is built to last, with stainless steel components that resist corrosion from acidic or alkaline wastewater. They also offer 24/7 technical support, a lifeline for plants that run round-the-clock. "When a hydraulic press breaks down, production stops," Phuong says.

8. WasteMaster Vietnam (Vung Tau)

Coastal Vung Tau is home to oil refineries, ports, and seafood processing plants—all of which generate wastewater that could harm the nearby South China Sea. Enter WasteMaster Vietnam, a supplier focused on protecting coastal ecosystems with a mix of wet process equipment and air pollution control system equipment. "A seafood processing plant in Con Dao was releasing water with high salt and oil content, threatening coral reefs," says marine biologist-turned-CEO Mai Tran. "We installed a wet process system that uses centrifugation to separate oil from water, then a UV disinfection unit to kill bacteria. Now, their discharge is so clean, it's almost drinkable!"

WasteMaster's love for the ocean shines through in their designs. Their equipment is built to withstand the corrosive coastal air, with galvanized steel frames and rust-resistant components. They also partner with local environmental NGOs to monitor the impact of their systems, ensuring clients' wastewater truly is safe for marine life. "We don't just meet regulations—we aim to exceed them," Mai adds. It's this passion that has made WasteMaster a favorite among coastal businesses, from Vung Tau's oil terminals to Phu Quoc's luxury resorts.

9. PureStream Technologies (Hue)

Hue's PureStream Technologies is proof that big results can come in small packages. Specializing in municipal wastewater and small-scale industrial solutions, this supplier offers compact water process equipment and dry process equipment that's perfect for towns, hospitals, and small factories. "A district hospital in Quang Tri needed a wastewater system that could handle blood, pharmaceuticals, and organic waste without taking up too much space," says founder Duc Le. "We installed a modular dry process system that fits in a room the size of a garage, treats 5,000 liters per day, and costs a fraction of a traditional plant."

PureStream's focus on simplicity is intentional. Their equipment is designed to be user-friendly, with color-coded controls and easy-to-follow maintenance guides, making it ideal for communities with limited technical expertise.
