Excel Linen Supply in Kansas City is the largest supplier of linens to the food and beverage industry in Kansas City and surrounding areas. After relocating their plant they were faced with very high waste water surcharges. They already had in place a Kemco DAF (Dissolved Air Flotation System) as their main treatment process. This system kept Excel in compliance with the local waste water treatment standards as far as prohibited contaminants were concerned but did not reduce enough of the dissolved contaminants to eliminate surcharges.*
