«Costs are reduced as the DAF flotation process requires less chemical pre-treatment for flocculation to occur. (cstwastewater.com)
They passed down the sewer and through flocculation and aeration tanks before being discharged into a quiet river. (newscientist.com)
This is achieved by exfoliating pre-treated graphite under a highly alkaline condition to trigger flocculation, a process in which the graphene layers continuously cluster together to form graphene slurry without having to increase the volume of solvent. (sciencedaily.com)
