Dunmore Recycling and Waste Disposal Depot needed to upgrade its leachate treatment solution to combat rising disposal costs. The site lacked upstream storage, so the leachate quality was highly variable, with ammonia reaching 2000 milligrams per litre.
Ammonia and nitrogen management is a critical challenge across many wastewater streams, including those generated by recycling facilities, waste depots, landfills, contaminated sites, meat processing facilities, fertiliser production industry and sewage treatment facilities. Elevated nitrogen concentrations are common and can pose compliance, operational and environmental risks if not managed effectively. In some cases, these streams may also contain organic contaminants, suspended solids and trace contaminants such as PFAS.
Nitrogen in leachate plants, meat works, the fertiliser industry and sewage typically presents as Total Kjeldahl Nitrogen (TKN), comprising ammonia, biodegradable organic nitrogen (such as proteins), and smaller fractions of non-biodegradable nitrogen.
Aerofloat specialises in designing and constructing custom treatment plants to address ammonia and nitrogen challenges across a range of applications. Our tailored approach delivers cost-effective, efficient and compliant solutions that align with site-specific conditions and regulatory requirements.
Effective ammonia and nitrogen removal is essential to maintaining compliance and protecting downstream infrastructure and receiving environments. Without appropriate on-site treatment, managing high and variable nitrogen loads can be costly and operationally inefficient.
Aerofloat supports waste, recycling and industrial facilities by delivering custom on-site treatment solutions that reduce operational burden while maintaining compliance.
Aerofloat delivers innovative ammonia and nitrogen treatment solutions, drawing on proven biological processes, cutting-edge technology and in-house engineering expertise. From initial design through to installation and ongoing optimisation, our wastewater specialists are committed to delivering adaptable, compliant and cost-effective systems tailored to each application.
While leachate treatment remains an important application area, our solutions are equally suited to a broad range of wastewater streams where ammonia, nitrate and total nitrogen management is critical.
Utilising 3D CAD modelling and innovative engineering, Aerofloat uses clever designs to address a range of challenges.
Aerofloat’s Australian manufacturing team will manufacture your wastewater treatment systems locally before installation.

Aerofloat specialises in industrial wastewater treatment. Its team of engineers manage the entire process, from in-depth process design with 3D modelling, to manufacturing, installation, commissioning and after care.
Effectively manage Total Kjeldahl Nitrogen (TKN), comprising ammonia, biodegradable organic nitrogen (such as proteins), and smaller fractions of non-biodegradable nitrogen.
Managing ammonia and nitrogen levels is a critical challenge across many wastewater streams and is often central to meeting environmental and trade waste compliance requirements. Streams such as industrial wastewater and leachate commonly discharge to sewer under trade waste agreements with local water authorities, where nitrogen loads – particularly ammonia – must be controlled prior to entering council sewer networks. Other contaminants, such as PFAS, may also be present as emerging considerations.
Elevated ammonia and nitrogen concentrations create significant challenges because:
As a result, trade waste agreements frequently impose strict limits on Total Kjeldahl Nitrogen (TKN), with ammonia typically representing the dominant fraction of the nitrogen load.
Aerofloat’s leachate treatment systems are designed to remove nitrogen at the source, reducing the burden placed on downstream sewer networks and treatment plants.
Depending on site requirements and discharge limits, our solutions can include:
In many cases, Aerofloat installs a biological treatment system at the client’s site that mirrors the core processes used by municipal treatment plants, effectively performing the nitrogen removal step before the wastewater enters the sewer.
This approach delivers compliance while supporting water authorities by reducing energy demands and complex treatment requirements downstream.
Nitrogen in leachate is typically present as Total Kjeldahl Nitrogen (TKN), made up of:
Aerofloat systems are designed to comply with very tight nitrogen limits, such as in Aerofloat’s Leachate Treatment Systems. PFAS, ammonia and nitrogen are almost always the primary compliance drivers.
PFAS is an emerging consideration in some leachate streams, particularly where sludge disposal, environmental risk or water reuse is involved.
Unlike ammonia, PFAS does not directly overload sewage treatment plants. However, it presents challenges related to:
Aerofloat has delivered PFAS treatment components, either integrated within broader treatment systems or supplied as the main treatment component where required. PFAS management is becoming a primary driver for leachate projects today.
Aerofloat delivers leachate treatment solutions through a fully integrated delivery model, including:
This end-to-end approach ensures clear accountability, streamlined delivery and long-term performance.
Aerofloat delivers a comprehensive range of solutions and technologies designed to manage nitrogen in the meat processing industry, as well as the effective treatment of leachate in landfills and recycling facilities, reducing operational costs and ensuring long-term reliability.
Explore our case studies below to discover the diverse and innovative ammonia and nitrogen plants Aerofloat has delivered for waste depots, recycling centres and meat processing facilities throughout Australia.
Dunmore Recycling and Waste Disposal Depot needed to upgrade its leachate treatment solution to combat rising disposal costs. The site lacked upstream storage, so the leachate quality was highly variable, with ammonia reaching 2000 milligrams per litre.
Aerofloat provided an effective leachate treatment solution at Dunmore. The system is operating well and has readily been able to treat load increases of up to fifty percent above the ammonia concentration basis of design. This has ensured a compliant and cost-effective result for Council meeting strict ammonia and nitrogen discharge limits to the sewer.
Aerofloat was engaged by the aquaculture company to design a wastewater treatment plant that would allow its new Tasmanian factory to meet the strict guidelines set by Tasmania’s Environmental Protection Agency (EPA).
Aerofloat is dedicated to designing, installing and maintaining high-functioning wastewater treatment systems that meet the ever-changing needs of landfills and recycling facilities. Committed to providing the highest standard of work and practices, Aerofloat delivers world-class solutions for unique waste challenges, boosting operational efficiency, saving costs, and ensuring full compliance.

As regulatory focus continues to sharpen on nitrogen management, ammonia removal will remain the defining challenge in wastewater treatment. At the same time, emerging contaminants will increasingly shape future system designs.
Aerofloat continues to invest in innovative biological treatment processes that can be deployed responsibly and effectively as the industry evolves.
Most wastewater treatment systems discharge to sewer under trade waste agreements. Water authorities focus on ammonia because:
As a result, trade waste limits for ammonia and TKN are typically stringent and increasingly enforced.
High ammonia concentrations:
Water authorities therefore require leachate generators to treat ammonia at the source, rather than relying on downstream municipal infrastructure.
Aerofloat specialises in on-site biological nitrogen removal, designed to reduce ammonia before discharge.
Core process elements include:
This approach effectively replicates and supplements municipal treatment processes at the client’s site.
Treatment configuration is tailored to regulatory requirements:
In anoxic reactors, nitrate is biologically reduced to nitrogen gas, which is released harmlessly to the atmosphere. This step is critical where total nitrogen discharge is regulated.
In certain sewer networks, nitrate presence can be beneficial:
Aerofloat designs wastewater treatment systems that balance treatment performance with sewer health.
