How to eliminate sewer surcharges with a simple, low-energy system
Pre-treatment of high-strength wastewater before discharging it to a municipal sewer can be challenging, especially if high levels of BOD, TSS and ammonia are present. But what if a simple, affordable, onsite solution was available to help meet pre-treatment requirements and avoid sewer surcharges?
Bishop Water combines two of its robust, easy-to-use treatment technologies—The Bishop Solids Management Solution and BioCord® Reactors—to create a scalable solution for a wide range of industrial and commercial applications. The process can handle high solids and nutrient concentrations for a fraction of the capital and operating costs of more complex, energy-intensive alternatives.
The wastewater first goes to Bishop Water’s Solids Management Solution. Unlike complex, energy-intensive mechanical dewatering equipment, the Bishop approach utilizes a passive dewatering process that achieves a high level of dry solids using only specially selected polymers, Geotube® filtration and gravity.
As the solids are pumped to the Geotubes, a polymer is added to retain non-soluble BOD, TSS, and other contaminants. The Geotubes also provide filtration and release clear water that is low in TSS, but may still contains soluble organics and nutrients.

This nutrient-rich filtrate is then transferred to a BioCord Reactor system for further treatment. BioCord Reactors provide a simple, robust process to remove soluble BOD and ammonia with very little operator oversight.
A BioCord Reactor is simply a modular frame that supports densely arranged strands of polymer fibres. These fibres provide a massive surface area for the growth of aerobic and anaerobic microorganisms that are ideal for enhanced biological treatment and maintaining regulatory compliance – even in cold weather conditions.

This integrated solution can be customized meet the specific size constraints, treatment requirements, and growth plans for each site. The system also incorporates a modular design that can be easily expanded as treatment needs change.
