Pilot & Rental DAF Units

Dissolved Air Flotation Equipment Rentals and Pilot Units

Dissolved Air Flotation Equipment Rentals are great when wastewater treatment systems go down for maintenance, when process alterations affect effluent quality, or when capital for purchasing and owning equipment is not available.

With a pilot DAF system you can gain insight on what level of effluent quality can be achieved, get real numbers for ongoing chemical costs, and see what volume of sludge is produced through the treatment process. That’s something design theory simply cannot do. 

DAF pilot and rental systems are available in flow capacities from 20-2,000 gpm in dissolved air, nitrogen, or gas configurations.

To obtain rental rates, inquirers should prepare application details, wastewater characteristics, and delivery time frame information.
