 Portable sediment tanks are intended to settle only sands, loamy sands, and sandy loams.  If polymer is added, these tanks will additionally be appropriate for settling loams, silt loams and silts.  Portable sediment tanks should be at least three feet deep and have a minimum of two baffled compartments.  The inlet and outlet pipe should be a minimum diameter of three inches.  To account for the settling of suspended sediments, one must determine the appropriate size of a tank.  Multiply the pumping rate (gallon per minute) by 1.83 (a factor that includes the conversion from gpm to cfs and the particle settling velocity for Soil Class 1) to calculate the surface area of a tank in square feet. Portable sediment tanks are intended to settle only sands, loamy sands, and sandy loams.  If polymer is added, these tanks will additionally be appropriate for settling loams, silt loams and silts.  Portable sediment tanks should be at least three feet deep and have a minimum of two baffled compartments.  The inlet and outlet pipe should be a minimum diameter of three inches.  To account for the settling of suspended sediments, one must determine the appropriate size of a tank.  Multiply the pumping rate (gallon per minute) by 1.83 (a factor that includes the conversion from gpm to cfs and the particle settling velocity for Soil Class 1) to calculate the surface area of a tank in square feet.
