Yearly Cost Savings

Municipal wastewater penalty costs can add up, even for smaller operations. Installing a DAF unit to treat effluent can offer a significant yearly cost savings. To see how much an operation with a 125 gpm flow rate could save, download the R5 DAF brochure (PDF).

Why Buy Pre-Engineered

  • To accommodate short lead times
  • Lower up-front cost compared to custom unit
  • In emergency situations, to get operations back online ASAP
  • To avoid municipal wastewater treatment charges

Our pre-engineered DAF units come in several tank sizes and recycle rates, allowing our process experts to optimize both the tank area and recycle rate to fit your operation’s specific needs.

Tank Dimensions Recycle Flow Range
3' x 17' (38 ft2) 25 – 50 gpm
4' x 22' (75 ft2) 25 – 100 gpm
6' x 28' (150 ft2) 75 – 200 gpm
7' x 45' (275 ft2) 75 – 375 gpm
