Sludge Management

No matter what size industrial facility, our team can apply a number of key technologies to harvest and process the sludge efficiently, cleaning your plant in an environmentally sustainable manner.

What is Sludge Management?

Sludge is a natural bi-product for many industries, including industrial wastewater treatment or sewage treatment plants, and is one which has the capacity to cause delays in production. Veolia utilises an innovative range of sludge harvesting and processing technologies as part of our complete waste management solution, including:

  • Sewage sludge farms
  • Settling ponds
  • Tank cleaning
  • Large-scale cooling towers

Harvesting sludge

In days gone by, we used super suckers and the trusty old bucket and shovel to remove sludge, waste and heavy oils, and while this still may have its place on smaller scale projects or when working in confined space areas, we now are able to utilise the latest robotic technologies, pelican dredges, centrifuge and dozers to extract the sludge from your industrial facility in an environmentally sustainable manner. The key benefit to this technology is the ability to keep your tanks online.

  • Hydro Dozer
    The dozer is a hydraulic driven small dozer which can be easily disassembled and used in a number of applications. This robotic application, with remote control station, allows the tank to remain online whilst sludge removal occurs and is ideal for removing slurry and bulk product inside a tank, open top tank or pond area; is very effective in a submerged state; and negates the need for manned entry and human exposure to sludge. Together with a progressive cavity pump, the Hydro Dozer is capable of harvesting up to 90m3/hr. of sludge.
  • Pelican Dredge
    The Pelican Dredge specialises in the removal of sludge and silt from lagoons, tailings dams, sewage ponds, lakes and waterways. As a key piece of our sludge management equipment, the Pelican Dredge is a self-propelled cutter suction dredge and is easily transportable, can operate in shallow water (600mm) and is able to pump sludge over long distances (500metres)

Sludge Management processing solutions

At Veolia we have three key sludge processing technologies, including:

  • Centrifuge
    The state-of-the-art centrifuge application is generally applied to the recovery of oil from crude oil tanks. The centrifuge works by spinning a stainless steel drum whilst simultaneously introducing the contaminated oil, and within this spinning, gravity is increased 100 times. Aided by the possible heat and flocculants, the oil and water become separated.
