Get ready for winter: BioCord™ reduces ammonia year round—even in cold weather

Worried about your lagoon system’s ammonia levels as the mercury drops? There’s still time to retrofit your lagoon system with BioCord™ and boost treatment performance and capacity.

Winter is around the corner and every budget-conscious plant operator needs to keep an eye on ammonia-removal processes, which slow down in cold weather and often mean additional operational costs.



Year round ammonia levels of less than 1mg/L can be maintained with BioCord™ Reactors—all for a fraction of the cost of new plant infrastructure. Best of all, it’s easy and quick to install, often taking less than a day.

“BioCord™ Reactors are an affordable way to meet compliance standards and ensure the cold weather doesn’t diminish a lagoon system’s nitrification and denitrification processes,” says Kevin Bossy, CEO of Bishop Water Technologies.

BioCord™ benefits:

  1. Quick and affordable boosted treatment performance and capacity
  2. Simple retrofit installation
  3. Extended operating life of lagoon
  4. Virtually maintenance-free

Improves treatment performance and capacity

How does it work? BioCord™’s densely looped polymer fibres, which are hung on modular frames, boost the biomass surface area of growth for aerobic and anaerobic microorganisms that remove ammonia in a lagoon.

BioCord™’s open-frame design allows superior treatment in cold weather because it ensures good circulation and avoids air diffuser clogging due to sludge build-up. The biofilm of microbacteria that accumulates is also better insulated.

BioCord™ also improves the removal of phosphorous, biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS), too.

Typically, microbial growth is seen within 48 hours, and consistent results are seen as early as one week, indicated by a drop in BOD. Daily declines in ammonia and COD, among other pollutants, appear within three weeks.



The efficient BioCord™ denitrification process also allows plant operators to reduce the denitrification rate and eliminate having to dose the system with a carbon source and alkali, potentially saving hundreds of thousands of dollars per year.

Upgrade your lagoon system and save money

BioCord™ Reactors offer a proven, affordable solution for budget-conscious small communities to upgrade their existing lagoon system within a tight budget and meet treatment standards throughout the year.

“We have lots of expertise in helping small communities find affordable treatment solutions without building new plant infrastructure,” says Bossy. “BioCord™ is a proven, simple technology for any plant operator wanting to ensure ammonia removal year-round.”

Research shows BioCord™ leads in treatment performance


BioCord was shown to be the most promising solution for full-scale testing—boosting treatment performance the most with the lowest energy and maintenance requirements—compared to two other treatment technologies, according to recent research from Queen’s University.

The research evaluated three different passive treatment technologies at Storring Septic lagoon system in Tamworth, Ontario, in 2015. 

The study showed that BioCord:

  • Reduces ammonia the most in all conditions
  • Provides best treatment during cold-weather conditions
  • Efficiently treats and processes more polluted septage
  • Increases ability to quickly recover from system shock
  • Requires the lowest energy and maintenance needs

BioCord’s open-frame design allows superior treatment in cold weather because it ensures good circulation and avoids air diffuser clogging due to sludge build-up. The biofilm of microbacteria that accumulates is also better insulated.



BioCord is a simple, affordable solution for budget-conscious communities to boost treatment performance and capacity while meeting updated regulatory standards. 

The research was conducted by graduate students Christine Gan and Geoff Hall under the supervision of Professor Champagne Pascal in the Department of Civil Engineering.

Green and cost-effective: Geotube® reduces carbon emissions and saves money


Did you know that Geotube® containers can significantly reduce the carbon footprint of a project and save money? 



In fact, in Zutphen, the Netherlands, Geotube® containers allowed dredged material to be dewatered, contained and reused on site as part of a harbour remediation project, drastically cutting the project’s carbon footprint and installation costs compared to a conventional solution that involves mechanical dewatering and hauling sediment and backfill.

In total, 18,000 m3 of harbour sediment had to be dredged and dewatered, most of it contaminated sediment that otherwise would have had to be trucked out for confinement in disposal facilities, which would have been an additional expense.

Natural dewatering process saves CO2

Geotube® containers solved the problem on site quicker, cheaper and with much less carbon emissions than the mechanical belt press technology. In fact, the Geotube® dewatering solution was calculated to emit only one-fifth the CO2 compared to the conventional mechanical solution. 

Little mechanical pumping is required for Geotube® containers to dewater contained sediment. Excess water drains from the Geotube® containers through the small pores in the geotextile skin, effectively dewatering and consolidating contained material. A chemical accelerant can also be used to speed up the process.

The containers can handle very large sludge volumes, achieving a very high solids capture rate with low capital investment. Best of all, the containers can be safely reused as ‘giant sandbags’ and are virtually immovable once in place.

No trucking back and forth saves money and carbon emissions

For Zutphen’s harbour project, Geotube® containers were filled with dredged sediment, dewatered on site and then cost-effectively reused to stabilize and raise riverbanks, replacing the need to haul in fill material. 

Geotube® containers don’t require a convoy of trucks carrying in and out of the site dredge, slurry, backfill or breakwater rocks across sometimes vast distances. Geotube® containers can be filled on site with dredged contaminated sediment saving time and money.

From harbours and groynes to beaches and wetlands, Geotube® containers have been customized to the diverse needs of clients world-wide.

Let Bishop Water’s expert team assist with all aspects of your project, including design, obtaining the appropriate permits, site preparation and installation.
