Sigma Dissolved Air Flotation (DAF) System

The sigma flotation unit is designed to treat wastewater with medium to high solids loading. The capacity of the Sigma units ranges from 500 to 1000 m3/hr.

The Sigma series are designed to create the optimal circumstances for easy separation of the solids. The large free surface area and long retention time guarantee an optimal separation performance.

The solids are collected in the sludge thickener and transported to the sludge cone with a low friction scraper system. The sludge can be discharged with the sludge pump for thickening or discharge.
