Reduce Sludge Volume

Because the WAO process also aims to reduce sludge volume we will spend more time describing this process under the section dealing with Volume Reduction. The other thermal sludge conditioning method is best-known as sludge pasteurization, and deserves more than just a brief overview. 

Use sludge dewatering equipment to reduce sludge volume.

In liquid-solid separation where acrylamide polymers act as flocculants and aids in mineral processing, waste treatment and water treatment. They also help reduce sludge volumes in these applications. 

Anaerobic sludge digestion at 30-35°C reduces sludge volume by about 90% while producing a medium-grade fuel gas of methane and carbon dioxide, in the mole ratio of roughly 2CH4 C02 (e.g., Eqs. 5.28-5.31, Fig. 5.9).
