Used Sigmadaf FPAC 160 Dissolved Air Flotation (DAF) System – 310,000 GPD Industrial Wastewater Treatment Unit

Used Equipment Facts About This Machine
Manufacturer
Sigmadaf
Product Overview
The Used Sigmadaf Dissolved Air Flotation (DAF) System, Model FPAC 160, is a high-capacity industrial wastewater treatment system engineered to efficiently remove suspended solids, fats, oils, grease (FOG), and other contaminants from process water. Previously used in a wastewater application and built in 2025, this system delivers exceptional clarification performance with a design flow rate of 310,000 gallons per day (215 GPM) and a hydraulic capacity of 705 GPM.
The FPAC 160 utilizes dissolved air flotation technology to separate contaminants by attaching microbubbles to suspended particles, causing them to float to the surface where they are removed by an integrated skimming system. Equipped with a 25 HP recirculation pump, 20 skimmers, and 388 square feet of flotation surface area, this DAF unit is designed for continuous, high-efficiency wastewater treatment across a wide range of industrial applications.
