Landfill Leachate Treatment Solutions
The Challenge of Complex Leachate
Leachate is one of the most challenging liquids to treat. As water percolates through a landfill, it creates a complex mixture of organic matter, heavy metals, nutrients, and highly persistent hazardous substances such as PFAS (per- and polyfluoroalkyl substances). Meeting today’s strict discharge limits and future environmental standards requires more than simple filtration—it demands advanced treatment technology that integrates biology, mechanical power, and hydrological control.
Eden Aquatech has 30 years of experience in designing solutions for these specific environmental challenges. By integrating our patented aerators and bioreactors with unique floating baffles and BioS microbes, we achieve a comprehensive reduction of pollutants tailored to the water’s composition and the chosen system configuration. Feel free to contact us for a free consultation regarding your specific water type and how we can best optimize treatment for your needs.
Floating Baffles – The Key to Maximum Retention Time and Precision
o achieve the highest possible treatment efficiency, nothing can be left to chance. The greatest risk in open lagoons and treatment systems is hydraulic short-circuiting, where untreated water creates “shortcuts” and passes through the treatment stages too quickly without being fully treated.
Our floating baffles eliminate this risk:
Elimination of Hydraulic Short-Circuiting: The floating baffles direct the water flow, ensuring every drop achieves maximum contact with the aeration system and the BioS microbes.
Optimized Retention Time: By extending the flow path, the microorganisms are granted the necessary time to break down even the most persistent and recalcitrant pollutants.
Prevention of Anaerobic Zones: The baffles prevent stagnation and ensure that oxygen from AirTURBO™ and the biological treatment in HolKof™ are distributed evenly throughout the entire volume.
BioS – Natural Microbiological Leachate Treatment
Our technology is built on biological principles and bioaugmentation—a method where we introduce specific bacterial cultures tailored to meet the unique challenges of your specific environment. This is an efficient and sustainable solution that enhances natural processes while reducing the reliance on chemicals and minimizing maintenance.
How Microbial Technology Works:
Degradation of Pollutants: Organic matter, ammonium, and hydrogen sulfide (H2S) are broken down into harmless byproducts such as water, carbon dioxide (CO2), and nitrogen—entirely without chemical additives.
Inhibition of Harmful Microbiology: Beneficial bacteria outcompete undesirable microorganisms, preventing the growth of pathogens and hydrogen-sulfide-producing bacteria.
Operational Reliability and Environment: The system is 100% natural and GMO-free. It not only reduces odor and corrosion but also lowers operating costs and improves the working environment.

AirTURBO™ RV2: High-Performance Aeration for Demanding Leachate
“The AirTURBO™ RV2 is a highly energy-efficient surface aerator, specifically developed to withstand the harsh environments of landfills and industrial leachate ponds. With over 200 installations in Scandinavia since the 1990s, this is a proven technology that creates the optimal conditions for effective biological treatment.
Why Choose AirTURBO™ for Leachate Treatment?
Maximum Aeration for Nitrogen Removal: By supplying large volumes of atmospheric air, a stable aerobic zone is created. This is critical for nitrifying bacteria to break down ammonium and effectively lower nitrogen levels in the water.
IE5 Technology Cuts Energy Costs by 50%: The aerator is equipped with an IE5-rated motor that reduces energy demand by up to 50%. During normal operation, it consumes only approx. 2.5–3.0 kW, ensuring very low operating costs over time.
Eliminates Odor and “Black Water”: Oxygen-depleted ponds often produce hydrogen sulfide (H2S), resulting in a black tint and a pungent odor. AirTURBO™ breaks the stagnation and eliminates odor issues through active aeration.
Robust and Low-Maintenance Design: Built for continuous duty, the system features soft-start and self-regulating speed to minimize wear and tear. This results in significantly lower maintenance costs compared to traditional systems.
Scalable Solution: The number of units is easily adapted to the surface area and pollution load. The system is also simple to install and relocate as operational needs change.
HolKof™ Bioreactor: Compact and Efficient Nitrogen Removal
HolKof™ is a patented, mobile bioreactor specifically designed to address one of the primary challenges for landfill operators: high ammonium concentrations. By combining the airlift pump principle with advanced biofilm technology, it creates a controlled environment where microorganisms can operate at maximum efficiency.
Why HolKof™ is Crucial for Leachate Treatment:
Extremely Large Active Surface Area: A standard unit provides over 1800 m² of active surface area for the biofilm. This is where beneficial bacteria effectively break down pollutants and organic matter.
Effective Ammonium Reduction: The process converts ammonium into harmless nitrogen gas in several stages, which is the most effective way to combat eutrophication.
Natural, Chemical-Free Purification: The system utilizes bioaugmentation to break down grease and hydrogen sulfide (H₂S) into byproducts such as water and carbon dioxide (CO₂).
Compact and Cost-Effective: HolKof™ is mobile and energy-efficient, making it an economically smart alternative to significantly more expensive stationary treatment plants.
Improved Working Environment: By eliminating undesirable microorganisms, both corrosion and disruptive odors from the pond facility are reduced.
