A greener approach for metallic parts cleaning industry: Microbubble flotation

Cleaning of oily-contaminated metallic parts is essential due to the increasing production of metallic components from the manufacturing industry. The conventional cleaning methods used are costly and unfriendly to the environment. Thus, this thesis establishes a new approach with high efficiency on cleaning oily-contaminated metallic parts and added with an extra ability to treats wastewater generated from metal cleaning process without compromising the environment. The overall low implementation costs and short payback periods allow this approach to be economically feasible and worth to be invested.
