EcoFlow Engineering, based in Zenica, has carved a niche in serving Bosnia and Herzegovina's industrial heartland. Specializing in effluent treatment for manufacturing, mining, and chemical plants, the company understands that industrial wastewater comes with unique challenges—high contaminant loads, variable flow rates, and strict compliance standards. Their answer? Robust, customizable systems built to withstand tough conditions.

At the core of their offerings is filter press equipment , a critical tool for separating solids from liquids in industrial processes. EcoFlow's filter presses are known for their durability; one client in the steel industry reported using the same unit for over eight years with minimal maintenance. They also excel in dry process equipment , which reduces water usage and sludge production—a boon for water-scarce regions like parts of central Bosnia.

"We started noticing a gap in the market for industrial-focused solutions," explains founder Marko Jović. "Many suppliers offered generic systems, but factories need equipment that can handle their specific waste streams. So we invested in R&D, working directly with clients to design machines that solve their real-world problems." This client-centric approach has led to partnerships with major names like ArcelorMittal Zenica and Bosnalijek Pharmaceuticals.

EcoFlow also prioritizes sustainability. Their dry process systems, for example, not only reduce water consumption but also recover valuable byproducts—like metals or organic matter—that can be reused or sold, turning waste into a resource for clients.

Nestled in the coastal city of Split (with a satellite office in Mostar), Adriatic Environmental Systems brings a Mediterranean perspective to wastewater treatment—prioritizing harmony between human activity and nature. With 15 years of experience, they specialize in systems that mimic natural water purification processes, making them a favorite for eco-conscious clients.

Their water process equipment often integrates constructed wetlands, biofilters, and natural sedimentation, reducing reliance on energy-intensive machinery. For clients needing more traditional solutions, their wet process equipment —including clarifiers and aeration tanks—are designed for efficiency and low maintenance. One memorable project was a resort in Neum, where they installed a hybrid system that treats wastewater using a combination of mechanical filtration and wetland plants, allowing the treated water to be reused for irrigation.

"We believe wastewater treatment shouldn't just be about compliance—it should be about restoring balance," says environmental engineer Lejla Kovač. "Our systems don't just clean water; they create habitats for local flora and fauna. It's a win-win for businesses and the environment." This philosophy has made them a go-to for tourism boards, wineries, and agricultural cooperatives across Herzegovina.

Adriatic Environmental Systems also offers training workshops for local communities, teaching them how to maintain small-scale treatment systems. "Knowledge sharing is part of our mission," Kovač adds. "If people understand how these systems work, they'll care for them better—and that's how we build lasting change."

Not every wastewater treatment project requires a massive plant. For villages, small towns, and rural businesses, Sava Water Solutions offers compact, affordable systems that deliver big results. Based in Banja Luka, the company has spent a decade perfecting equipment that's easy to install, operate, and maintain—even for communities with limited technical expertise.

Their compact water process equipment includes modular treatment units that can be scaled up as a community grows. A typical system might combine a septic tank, aerobic filter, and disinfection unit, all housed in a space no larger than a small shed. For clients with stricter discharge requirements, their effluent treatment machine equipment adds advanced filtration, ensuring water meets EU standards for release into sensitive ecosystems.

"We started Sava because we saw too many small communities struggling with outdated, failing septic systems," says co-founder Mirna Petrović. "They couldn't afford the large-scale plants offered by bigger companies, so they just kept dumping untreated wastewater into rivers. It was heartbreaking. Now, we provide systems that cost a fraction of the price but still meet high standards."

One of their proudest projects was the village of Lukavac, where they installed a community system serving 300 households. Before, raw sewage flowed into the Sava River; now, the treated water is clean enough to support fish and wildlife. "The villagers even organized a celebration when it was finished," Petrović recalls. "That's the reward—seeing the direct impact on people's lives and the environment."

For businesses and municipalities looking to address multiple environmental challenges at once, BiH GreenTech Industries offers a one-stop shop. Founded eight years ago in Sarajevo, the company combines wastewater treatment with air pollution control system equipment , helping clients meet both water and air quality regulations with integrated solutions.

Their effluent treatment machines range from compact units for small businesses to large-scale plants for industrial zones. What sets them apart, though, is their ability to pair these with air pollution control systems—like scrubbers, filters, and dust collectors—creating a seamless environmental management plan. This integrated approach saves clients time, money, and logistical headaches, as they only need to work with one supplier for multiple compliance needs.

"We noticed that many clients were juggling separate contracts for water and air treatment, leading to miscommunication and inefficiencies," says CEO Alen Hadžija. "So we decided to offer a full suite of services, from design to installation to maintenance, for both systems. It's about making environmental compliance less of a burden and more of a strategic advantage."

BiH GreenTech has made waves in the hospitality sector, partnering with hotels and resorts in places like Jahorina and Bjelasnica to reduce their environmental footprint. One ski resort, for example, now uses their effluent treatment machine to clean wastewater and an air pollution control system to reduce emissions from heating and kitchen operations—all managed through a single, user-friendly control panel.

Bosnia and Herzegovina's food and beverage industry is a source of pride—think rakija distilleries, dairy farms, and fruit processing plants. But it's also a major source of wastewater, rich in organic matter that can deplete oxygen in rivers and lakes if left untreated. Enter Vrbas Process Engineering, a Novi Sad-based company (with a strong presence in Banja Luka) that has spent 14 years perfecting solutions for this vital sector.

Their filter press equipment is a star player here, used to separate solids like fruit pulp, grain husks, or dairy sludge from wastewater. The recovered solids are often repurposed as animal feed or fertilizer, turning waste into a revenue stream for clients. They also offer wet process equipment tailored to the food industry's high water usage, with features like heat recovery to reduce energy costs.

"Working with food producers is rewarding because you're not just protecting the environment—you're supporting local agriculture and tradition," says lead engineer Ana Petrović. "Many of our clients are family-owned businesses that have been around for generations. They care about their communities, and they want to do right by the land. We help them do that without sacrificing profitability."

A recent project with a large winery in the Posavina region exemplifies their impact. The winery was struggling with high BOD (biological oxygen demand) levels in its wastewater, risking fines and damage to the local ecosystem. Vrbas installed a custom wet process system with a filter press, reducing BOD by 90% and recovering grape pomace that's now sold as a natural fertilizer. "The owner told us it was the best investment he'd made in years," Petrović laughs.

With over 20 years of experience, Drina Water Technologies is a veteran in Bosnia and Herzegovina's wastewater treatment scene. Based in Bijeljina, they've built a reputation for handling the most complex projects—think large mining operations, chemical plants, and municipal systems serving over 100,000 people. Their secret? A combination of engineering expertise, cutting-edge technology, and a willingness to take on tough problems.

Their dry process equipment is a game-changer for water-scarce industries like mining, where traditional wet treatment would strain local water supplies. Dry processes use filtration, evaporation, or centrifugation to treat wastewater with minimal water loss, making them ideal for arid regions. They also offer heavy-duty water process equipment for municipal plants, including advanced membrane bioreactors that produce high-quality effluent suitable for reuse in irrigation or industrial processes.

"We've never shied away from a challenge," says company president Muhamed Džeko. "Early on, we took on a project for a lead-zinc mine that had been struggling with wastewater compliance for years. Everyone told us it was impossible, but we spent six months researching their waste stream, designing a custom system, and testing it rigorously. Now, that mine is a compliance success story."

Drina's long history has also given them deep roots in the community. They sponsor environmental education programs in local schools and offer internships to engineering students, ensuring the next generation of wastewater professionals has hands-on experience. "This industry is about more than machines," Džeko adds. "It's about building a legacy of clean water for Bosnia and Herzegovina's future."

Ilidža, a suburb of Sarajevo known for its thermal springs and parks, is also home to Ilidža Environmental Group—a company with a mission to make wastewater treatment accessible to small towns and neighborhoods. For 11 years, they've focused on community-scale projects, working closely with local governments and residents to design systems that fit their needs and budget.

Their effluent treatment machines are designed for ease of use, with simple controls and low maintenance requirements—perfect for small communities without dedicated plant operators. They also offer compact water process equipment that can be installed in tight spaces, like urban lots or alongside existing infrastructure. One popular model, the "MiniClean 500," serves up to 500 households and fits in the footprint of a two-car garage.

"We believe that clean water is a right, not a luxury—for every community, no matter how small," says community outreach director Lejla Begić. "That's why we work directly with local leaders to secure funding, apply for grants, and educate residents about the benefits of wastewater treatment. It's not just about installing a machine; it's about building community support."

A standout project was the town of Kiseljak, where Ilidža helped secure EU funding to ｒｅｐｌａｃｅ an outdated septic system with a modern treatment plant. The project included workshops for residents on water conservation and tours of the new facility, turning skepticism into pride. "Now, the plant is a point of community pride," Begić says. "Kids from the local school even visit for field trips to learn about environmental science. That's how you create lasting change."

Tuzla, a city in northern Bosnia, is a hub for both agriculture and industry—two sectors with very different wastewater needs. Tuzla Water Systems, founded 16 years ago, has made it their mission to serve both, offering specialized solutions for farms, food processors, and factories alike. Their versatility has made them a trusted name across the region.

For agricultural clients, their wet process equipment handles manure, crop wash water, and pesticide runoff, often incorporating anaerobic digesters that produce biogas for heating or electricity. For industrial clients, their filter press equipment is a workhorse, separating solids from manufacturing waste and reducing sludge disposal costs.

"We love the diversity of our work," says sales director Emir Hodžić. "One day, we're designing a system for a dairy farm in Brčko; the next, we're installing a filter press for a textile factory in Tuzla. Each project teaches us something new, and that knowledge makes us better at solving problems for all our clients."

Tuzla Water Systems also prioritizes affordability, offering flexible financing options and leasing programs for small businesses. "Not everyone can afford to buy a treatment system outright," Hodžić explains. "By offering leases, we help them get the equipment they need now, with payments spread out over time. It's about making compliance possible for everyone, not just the big players."

The youngest company on our list, Mostar EcoEngineering has quickly made a name for itself with innovative, future-forward solutions. Founded just nine years ago, the company focuses on emerging technologies like AI-driven process control, modular design, and resource recovery—positioning itself as a leader in the next generation of wastewater treatment.

Their advanced water process equipment often includes smart sensors and automation, allowing systems to adjust in real time to changes in wastewater composition. This not only improves efficiency but also reduces the need for constant human monitoring. They're also pioneers in dry process equipment that incorporates solar power, making treatment systems more sustainable and less reliant on the grid.

"We started with a simple question: What will wastewater treatment look like in 20 years?" says founder Luka Marić. "We realized it would be smarter, more efficient, and more integrated with other systems—like energy production or resource recovery. So we built our company around that vision."

One of their most exciting projects is a pilot plant in Mostar that uses AI to optimize treatment processes. The system learns from historical data, weather patterns, and even local events (like festivals or sports games) to predict wastewater flow and adjust treatment parameters accordingly. Early results show a 25% reduction in energy usage compared to conventional systems. "It's still in the testing phase, but we're already seeing how technology can transform the industry," Marić says.
