Sludge Treatment

When wastewater is treated either biologically or through physical/chemical methods, sludge is produced. The disposal method for the sludge and the associated costs can significantly affect the payback and economics of a wastewater treatment plant installation. Ovivo has experience treating sludges from all types of municipal and industrial wastewater systems and is able to offer solids handling equipment for sludge thickening or dewatering. 

Our Treatment technologies

Ovivo has been an industry leader in developing and delivering sludge treatment solutions for over 40 years.  Whether you are interested in generating energy from the sludge by using anaerobic digestion or in minimizing nutrients by using aerobic digestion, Ovivo has the technology and equipment to suit your particular application.  Our equipment offerings include the following:

Anaerobic Digestion

  • Covers; fixed and floating
  • Mixers; internal and external draft tube, and LM™ linear motion 

Aerobic Digestion

  • Medium bubble diffusers
  • Draft tubes
  • Shear tubes
  • Covers

Our Sludge handling technologies

Ovivo has a wealth of experience in the vast array of sludge thickening and dewatering technologies; we have on many occasions supplied other OEM technologies as elements to our total project delivery. These include:

  • Gravity thickening
  • Membrane thickening
  • Flotation thickening
  • Belt thickening
  • Drying bed design
  • Filter press
  • Belt press
  • Centrifuge

In addition, we are particularly proud of the CINETIK® electrode dewatering technology, our latest innovation in this area, which uses electricity and controlled mechanical pressure to induce electro-osmosis and extract water from mechanically dewatered sludge cake.

Performance

The performance of our treatment technologies is guaranteed to meet regulatory requirements in a cost effective and energy efficient manner.  The performance of our solids handling equipment is unparalleled in durability, ease of operation and consistency.  Combining Ovivo’s expertise in these areas ensures that the solution provided for your facility will be one that minimizes total project cost while maximizing energy production, nutrient management and solids concentration.
