Mobile Dissolved Air Flotation Clarifier

Efficient Solids Removal in a Compact Footprint

WesTech’s mobile dissolved air flotation (DAF) units deliver rapid, high-performance removal of suspended solids, fats, oils, grease (FOG), and hydrocarbons for temporary or on-demand treatment across municipal and industrial applications.

Engineered for fast setup and simple operation, mobile DAF systems provide consistent flotation performance using integrated air induction and proven skimming technology. Available in both carbon steel and 304 stainless steel configurations, the compact footprint makes them well-suited for constrained sites and short-term deployments.

Whether supporting emergency response, plant maintenance, peak loading, or temporary treatment projects, the mobile DAF fleet can operate as a standalone solution or integrate into multi-stage mobile treatment systems, supported by WesTech engineering, startup, and operations teams.

Use Cases

The Mobile Dissolved Air Flotation (DAF) Clarifier delivers fast, effective solids removal and thickening wherever temporary or mobile treatment is needed. It’s ideal for short-term projects, emergency response, or remote locations where fast deployment and reliable performance are critical. Common applications include:

  • Municipal bypass treatment during clarifier or filter maintenance
  • Industrial pretreatment for suspended solids or oil and grease removal
  • Frac water clarification in oil and gas operations
  • Waste activated sludge (WAS) thickening ahead of sludge dewatering or hauling
  • Seasonal or regulatory surges that exceed existing plant capacity for solids concentration or clarification
