Slurry phase biological treatment
Webb25 nov. 2013 · This process includes preparation of treatment beds, biotreatment cells, and soil piles or composting. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance biodegradation. These technologies differ from landfarming since the treatment processes are often enclosed to control off-gases. WebbSlurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination …
