Transform your sanitation operation into an act of respect for nature.
Water must always be clean. Treating wastewater should mean regenerating water!
The choice of processes in a wastewater treatment plant, or the "technological layout," is crucial for successful long-term operation. Balancing compliance with legal requirements with economic viability and operational simplicity is the key to success.
Sanitation needs to be more than universal; it needs to be perpetual! The challenge isn't just implementing the wastewater treatment plant. The challenge is ensuring compliance with discharge limits, all the time and forever.
In an increasingly demanding environment in terms of quality and socio-environmental responsibility, treatment solutions must transform sanitation operations into an attitude of respect for nature.
The key to the economic viability and long-term sustainability of the operation is the ability to deliver high efficiency with operational simplicity. This is what guarantees economically viable operations and long-term stability.
Our treatment systems integrate constructed wetlands using classic engineering techniques in designs tailored to the specific needs of each client.
Implementing the wastewater treatment plant is just the beginning...
The difficult part is guaranteeing stability and efficiency in the long term.
More than 75% of wastewater treatment plants (WWTPs) that will serve Brazilian municipalities have treatment flow rates of less than 30 L/s. In other words, these are flow rates equivalent to a population of less than 20,000 inhabitants.
In industries and mining operations, the population sizes of wastewater treatment plants are even smaller! An industrial or mining plant with 1,000 employees generates a sanitary sewage flow rate of less than 1.0 L/s. These flows correspond to a population equivalent of only less than 500 inhabitants! And this reality presents several challenges:
1
Financial limitations and a shortage of skilled labor to operate and maintain intensified processes.
2
Difficulty with solid phase management: dewatering, treatment and disposal of sludge.
3
Characteristics of effluents commonly outside the typical ranges described in the literature for domestic sewage.
4
Large fluctuations in daily hydrographs with load shocks alternating with periods without feed.

Wastewater Treatment Plant using Constructed Wetlands
Wastewater Treatment Plants (WWTPs)
Wetland wastewater treatment plants (WWTPs) are treatment plants that employ constructed wetland technology as their primary process. They are applicable for flow rates below 25 L/s, but are ideal for flow rates between 1.0 and 10 L/s or an equivalent population of less than 5,000 inhabitants.
Accessory equipment for disinfection or physical-chemical removal of phosphorus can be integrated into the arrangement, creating systems according to demand.
The main advantages of wetland wastewater treatment plants are the integrated sludge mineralization within the bed itself, which dramatically simplifies operation and maintenance routines, and the reliability of the process due to its high performance stability.
Depending on the required final quality, it is possible to use one or two stages, work with partial saturation of the support medium, and even vary between natural ventilation or forced aeration. For example, it is possible to assemble simplified configurations to deliver BOD values lower than 60.0 mg/L or systems that deliver advanced removal of organic matter and ammonium, reaching BOD values lower than 5.0 mg/L and total nitrification!
Combined Systems
Global experience is vast in combining processes integrating constructed wetlands with septic tanks, compartmentalized reactors, UASB reactors, and anaerobic filters. There are also various combinations with trickling filters, activated sludge, and lagoons. An advantageous process combination in the Brazilian context is integration with UASB reactors in municipal wastewater treatment plant retrofit projects.
In cases where an asset already exists on-site, wetlands fit in as a post-treatment step, delivering advanced removal of organic matter, retention of suspended solids, and partial or total nitrification. Combinations employing wetlands for sludge treatment are also very advantageous!
Whether for the treatment of aerobic, anaerobic, or mixed sludge, UGL Wetlands deliver significant reductions in costs and operational complexity. Whether for the liquid or solid phase, in association with anaerobic or aerobic processes, constructed wetlands offer the balance that operations need to remain viable over time!
Wastewater Treatment Plant Retrofit
Wastewater treatment plant retrofitting is the revitalization and modernization of treatment plants, updating them with new technologies and processes to meet new requirements and increase their lifespan, without necessarily rebuilding everything. The goal is to adapt the old structure to the new reality, improving the overall efficiency of the wastewater treatment plant.
One very interesting retrofit model is the renovation of stabilization ponds, one of the most widely used technologies in Brazil. Situations where ponds are no longer adequate for current requirements are quite common, either due to limitations in the process's ability to remove certain parameters or due to the plant's own collapse.
In these cases, our team develops the best intervention strategy for each location, employing a wide range of technologies that allow for the station's re-adaptation.
There are situations where small interventions in the process, while maintaining the lagoons as the main route, are sufficient. Other situations require the complete conversion of the processes, for example, installing a Wetlands wastewater treatment plant within the existing lagoon. And there are still cases where the lagoons can be converted into activated sludge systems combined with UGL Wetlands.
Systems for producing reclaimed water
The configuration of the treatment process for producing reclaimed water depends on the intended type of reuse. More demanding uses, such as water for cooling towers and washing structures, require different treatment processes than less demanding uses, such as crop irrigation or dust control. The intended use determines the process arrangement!
The challenge in maintaining the reuse plant operationally and economically viable over time lies in the proper selection of the processes that make up the treatment system, avoiding unnecessary over-processing and employing the correct techniques for the wrong purposes!
When integrated with other processes aimed at producing water for reuse, constructed wetlands ensure a balance between operational and economic viability, effortlessly producing water as needed.
Assisted or outsourced operation
Our team is prepared to provide you with the necessary support for your operation. Whether it's operational assistance contracts or outsourced operations, the first step is a diagnosis of the situation. The process in question needs to be analyzed by our team to define the scope of work and assess any necessary investments to correct problems.
Once in our hands, the commitment will be to guarantee excellence in performance and operational safety at the lowest viable cost.
