ModularFAST

The ModularFAST® is a treatment system specially designed to accommodate the constant fluctuations encountered by small-flow, on-site municipal applications – from high flows caused by infiltration during a storm to low flow weekends at a school. Such flow fluctuations demand a wastewater treatment system that can adapt quickly, like the ModularFAST® by Smith and Loveless.

  • The high-quality effluent extends leach field life and can reduce the size of the leach field required in some soils.
  • The system handles wide variations of flow with no washout of the biomass because it is an attached growth system.
  • The design is aesthetically pleasing because it allows the system to be completely below grade, if desired, and located in close proximity to buildings and public areas.
  • The ModularFAST® is less expensive than standard pre-fabricated package treatment plants.
  • The system requires minimal operator attention and no return activated sludge.
  • Achieves nitrification and denitrification.

Proven Applications:

  • Schools,
  • Resorts and hotels
  • Restaurants
  • Botanical gardens
  • Office buildings
  • Municipalities
  • Apartments
  • Shopping centres
  • Golf courses
  • Rest areas, camps and parks.

ModularFAST® – How It Works:


With three treatment steps in one tank, the ModularFAST® is ideal for on-site treatment applications. Infulent enters the system and is circulated through the submerged media in the aeration tank. Bacteria are then “fixed” or attached to the media. This prevents hydraulic peaks from washing the bacteria out while providing a higher surface area-to-volume ratio. A zone underneath the media exists for the sludge to settle and collect for further digestion in an anaerobic environment. The ModularFAST®’s advance treatment levels allow for a variety of discharge arrangements.
