Simultaneously separates LNAPLs of 60 microns and larger by flotation and removes settleable solids and dense non-aqueous phase liquids (DNAPLs) which sink and are collected in the base before being drawn off. It suits cases where higher suspended solids / DNAPL are envisaged and has a large sludge storage volume and the option for continuous on-line removal of solids.

Key features

  • No power requirements and easy to operate

  • Handling flows of 20m³/hr depending on application

  • Designed in accordance to API 421

  • Will also cope with a high suspended solids/grit load

  • Twin hopper to reduce the frequency of sludge removal required

  • Integral storage tank for secure temporary storage of the recovered hydrocarbons

  • Hydrocarbon: LNAPL and DNAPL

  • HB20-OWS also available

Typical applications

  • Remediation of gas and oil works

  • Continuous pumping
