THE OPPORTUNITY!

The Original Cakerie is looking for a Wastewater Treatment Operator for our London location. The Wastewater Treatment Operator is responsible for running a small mechanical/chemical treatment plant designed to reduce Oil & Grease and TSS loadings in order to meet The City of London sewer by-law discharge levels. The incoming waste stream is a combination of miscellaneous discharges from floor drains and other operational processes from the main facility.

Water from the equalization tank enters the treatment plant and first passes through a strainer screen to remove large particulate matter from the stream. The water then enters a large Dissolve Air Floatation Unit (DAF), where mechanical and chemical processes separate the wastes into a floating sludge. The sludge is skimmed off the DAF, collected and removed from site for further processing.

The DAF effluent is discharged to the city sewer
