Pipe Size:
Where an oil separator is required, loading docks are generally sized based on the influent flow rate. Take into consideration whether the area is covered or uncovered, and what flow sources may enter the oil separator in gallons per minute.

If flow rate exceeds 300 GPM, please contact Striem
Pipe Size:
Where an oil separator is required, airport hangars are generally sized based on the influent flow rate.
Take into consideration what flow sources (e.g., hose bib) may enter the oil separator in gallons per minute.

Choose washer size and quantity
Volume Total must be greater than zero.
Sizing Assumptions:
- Water usage factor per lb. of dry clothing: 0.75 gal.
- Number of fills and dumps per cycle: 3
- Washer outlet flow rate: 30 GPM
- Trough drainage flow rate: 60 GPM
Please note: To accommodate space constraints and piping configurations, our sizing tool limits the TT-3 to a maximum of (2) washers and the TT-6 to a maximum of (4) washers
