Mobile Organic Biofilm (MOB) Technology

This Advance Contract Award Notice (the “ACAN”) is issued by the City of Saskatoon (the “City”) to notify the supplier community that the City intends to award a contract to a pre-identified Supplier, believed to be the only one capable of satisfying the City’s requirements. The ACAN is intended to allow other Suppliers an opportunity to signal their interest in competing for the Contract by submitting a statement of capabilities that clearly demonstrates the Supplier’s ability to satisfy the requirements. If no Supplier submits a statement of capabilities that meets the requirements set out in the ACAN, on or before the submission deadline stated in the ACAN, the City may proceed to award a Contract to the pre-identified Supplier. The City requires: Mobile Organic Biofilm (MOB) technology that can be utilized in an activated sludge system to support the growth of nitrifiers, creating a stratified microbial community which facilitates simultaneous biological nutrient removal. The MOB particles are required to flow between reactor zones and into the secondary clarifiers where they must settle. The MOB particles must be retained in the system through the use of separation devices such as a rotary screen and returned to the bioreactor.
