Prescribed Waste Treatment

Innovative solutions

The treatment of contaminated wastes can be a difficult process in order to provide cost-effective outcomes.

Success is very much predicated on having a solid technical understanding of complex chemical and biological interactions, coupled with a pragmatic approach to ensure a cost-effective outcome.

The treatment of contaminated wastes is a core area of expertise for Ennovo. This ranges from industrial waste, groundwater, contaminated soil, and surface water, involving an array of projects. These treatment processes have involved a broad range of contaminants in a range of mediums such as:

  • Heavy metals
  • Petroleum hydrocarbons (TPH)
  • Benzene, ethylbenzene, toluene and xylene (BTEX)
  • Polycyclic aromatic hydrocarbons (PAHs)
  • Gasworks waste
  • Per- and polyfluoroalkyl substances (PFAS)
  • Organochlorine pesticides (OCPs)
  • Acid sulphate soils (ASS and PASS)

The treatment approach differs depending on the contaminant type and composition, and the matrix it is contained within. Ennovo personnel have experience in designing and operating a range of treatment equipment and processes including packaged water treatment plants, specialised soil treatment machines such as the Komatsu Reterra, and facility fixed plant equipment. The processes undertaken include the following:

  • Chemical Fixation and Stabilisation (CFS)
  • Bioremediation
  • Chemical reduction
  • Chemical oxidation
  • Absorption and adsorption
  • Ion exchange

Ennovo also have laboratory facilities that allow treatment trials to be undertaken. These trials can be used to develop new treatment approaches, optimise existing approaches or to gain regulatory approvals. Our skilled scientists and engineers are able to design and develop a fit for purpose treatment approach to meet required outcomes.
