BioCord™ Reactors provide a simple, low-energy, fixed-film biological treatment process to dramatically increase the capacity and performance of wastewater lagoons and conventional activated sludge systems. Modular BioCord Reactors are like condominiums for bacteria, incorporating a customizable design that rises up through the water column to suit virtually any treatment conditions and plant design. The reactor frame supports densely arranged loops of polymer fibers that provide a massive surface area on which preferred, naturally occurring bacteria can thrive.

Integrated aeration grids powered by low-energy compressors
Each BioCord Reactor is equipped with a fine-bubble aeration system that provides the optimum level of oxygen transfer and mixing to support bacterial growth and nutrient removal. The mixing and agitation also helps slough excess biofilm from the media to maintain the ideal colony size and composition.

Install – Aerate – Grow
BioCord Reactors are installed directly into an existing treatment system, which helps to dramatically reduce capital costs by avoiding expansion to the plant footprint or adding side stream process tanks. Once installed, a BioCord Reactor system is self-regulating, uses very little electricity, and requires almost no operator oversight to achieve its performance targets. These capital and operational benefits make BioCord Reactors the ideal solution to improve treatment capacity, accelerate nutrient removal and achieve regulatory compliance.
An optimized BioCord Reactor system is capable of achieving significant reductions
in target nutrients and other constituents, including:
- Ammonia: 90% or greater;
- Total nitrogen: 50% or greater;
- BOD: 80% or greater.
BioCord Reactors are ideal for increasing treatment capacity and improving nutrient removal in multiple applications:
- Municipal wastewater lagoons
- High-strength wastewater treatment to reduce ammonia, phosphorus and suspended solids
- Food processing
- Agriculture
- Mining
The advantages of BioCord Reactors

Dynamic Ammonia Removal
Whether it’s cold-weather, high strength, or more stringent regulations for ammonia treatment, BioCord Reactors can achieve up to 99 per cent ammonia removal, even when operating in temperatures as low as 1°C.
Customizable design, performance and deployment, BioCord Reactors offer a flexible, modular design that can be customized to fit virtually any type of secondary treatment process and to handle anticipated flow and loading parameters. Capital costs can be kept low by installing only the required amount of BioCord Reactors to achieve performance requirements and can be easily expanded in planned phases as treatment needs increase.
Rapid Capacity Expansion
Treatment plant capacity can be expanded significantly to meet performance requirements and produce tertiary quality effluent. The BioCord Reactors and accompanying aeration system can be delivered to the site fully assembled. Installation is completed in just a few days, while the plant remains in operation
Trusted, Resilient Performance
BioCord Reactors are self-regulating systems that respond quickly to variable influent or upset conditions and can continue to meet treatment requirements without operator attention or process modifications. The multi-compressor design also simplifies maintenance since an individual unit can be shut down for service, while the others continue to operate and maintain system performance.
Low Capital and Operating Costs
BioCord Reactor systems require no additional tanks or costly, energy-intensive blowers to operate, providing significant savings in capital and operating costs – often about 50% less than an MBBR system designed to achieve the same ammonia target. Moreover, a BioCord Reactor system is self-regulating and self-cleaning, requiring virtually no operator oversight and maintenance.
Compact Pilot Systems Available
Evaluate BioCord Reactor performance at your facility with a compact pilot system.
A compact BioCord Reactor pilot system can quickly demonstrate the performance and operational benefits that this fixed-film technology can bring to a treatment plant.
The simple pilot system can often be installed and operated alongside the existing treatment process without any modifications to the current Certificate of Approval.
Data from the pilot study will not only validate BioCord Reactor capabilities, it also enables WaterSolve engineers to prepare a full-scale system proposal and show the ease and simplicity of adding BioCord Reactors to the existing process.
