Flocculation Tubes

ETS FT-Series Flocculation (Floc) Tubes are hydraulic flocculators that use the energy of the wastewater flow to mix the wastewater with chemicals, encouraging coagulation and flocculation. Floc tubes are commonly used prior to dissolved air flotation (DAF) systems. The ETS floc tube is constructed from PVC or CPVC pipe, with each unit having pipe of two different sizes to improve performance over a wider range of flows. The larger of the two pipe sizes is used in the straight pipe runs to provide gentle mixing and increase the hydraulic retention time. The turns are constructed using the smaller pipe size to increase mixing and backmixing.
