DISSOLVED AIR FLOTATION SYSTEM

DESCRIPTION

The DHI Dissolved Air Flotation system uses MICRO-BUBBLE technology to remove suspended solids and hydrocarbons from produced water. Designed and built in a standard frac tank footprint for mobile convenience. The equipment is epoxy lined on all surfaces. All insert components are 316 or 304 stainless steel to prevent any contact with metals that may interact with chemistry.

The system incorporates DHI’s proprietary skimmer, process design, and level adjustment systems.

The waste product evacuates from the trap compartments, and clean fluid flows freely to the buffer compartment for pumping to the storage facility.

The DAF works with other DHI treatment equipment as needed. This includes Oil separators, Filtration equipment, chemical dosing systems and pumping solutions.

TECHNOLOGY

Microscopic air bubbles are produced during normal operation and mixed with waste water containing the suspended contaminates. The small bubbles attach themselves to the suspended particles, which gives them a net positive buoyancy. These buoyant clusters of particles and bubbles rise smoothly to the surface forming a float which is removed by skimming.
