We are pleased to announce that we have been awarded the contract to supply a total of five Boerger Rotary Lobe Pumps (Models FL518 and CL390) for the City of Medicine Hat – Water Treatment Plant (WTP) Residuals Management Facility. These pumps are to ship to site this week, and we are very excited to see these pumps up and running!

“The BLUEline rotary lobe pump has been used successfully in different sectors for many years. The high reliability and long service life of the pump convince our customers. The BLUEline rotary lobe pump is available in 21 different sizes. With flow rates between 1 and 6,400 usgpm (1 and 1,440 m³/h), there is always a pump which is perfectly suited to every single application.  Börger Rotary Lobe Pumps are self-priming, valveless, positive displacement pumps.

The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.” Source: http://boerger.com

The City of Medicine Hat WTP is located on the same lot as the Power Plant and was originally constructed in 1912. It has had multiple upgrades and expansions to accommodate new technology and predicted water demand until the year 2025. Since April 10, 2023, crews have begun construction on the Residuals Management Facility (RMF) at this City’s WTP. This project “will improve water quality in the South Saskatchewan River by reducing the amount of bound chemical solids from the treatment process released into the river.

Water treatment residuals are particulate solids combined with chemicals generated in the normal course of treating and disinfecting potable water at a water treatment plant.

As part of its Approval to Operate a Water Treatment Plant issued by Alberta Environment and Protected Areas (AEPA), the City is required to construct a Residuals Management Facility that would limit the amount of solids discharged into the river to below 25 milligrams per litre of total suspended solids (TSS) by the end of 2024. This is a phased requirement of all treatment plants in Alberta to sustainably preserve our natural water resources.

The facility will thicken and dewater the solids after they have been removed through the water treatment process and prepare them for transport to the landfill rather than return them to the river.” Source: http://medicinehat.ca
