Key Restraints :
Presence of alternatives is hampering the market
Flocculation is a method of oil and water separation that uses recycled additives to enhance the separation of oil. It is a process where a chemical coagulant is added to water, which helps in facilitating bonding between particles. This method has wide applications in water clarification, solid removal, sludge thickening, and others. Also, the bioinspired oil water separation process is another substitute for this market. This separation process is a sustainable way to remove the oil and other contaminants from the oil and water mixture. Hence, the analysis of market trends shows that the rising demand for substitutes of oil water separator devices is hampering the oil water separator market demand.
Future Opportunities :
Advancement of smart technologies and automation is expected to propel the market
Artificial intelligence combined with advanced sensors in these devices helps in real-time monitoring and provides enhanced accuracy and responsiveness. These advanced products also help in less consumption of energy and provide greater efficiency in oil removal. Also, automation leads to cost savings and mitigates the manual labor involved. Thus, technologically advanced product launches by the oil and water separator manufacturers are expected to propel the market over the forecast period. For instance, in February 2023, Alfa Laval launched an advanced oil water separator product named PureBilge Compact which is known for easy installation, reduction of operating cost, and is one of the sustainable products.
