Limited Compatibility with Changing Wastewater Composition
Wastewater composition can vary significantly depending on factors such as technical processes, seasonal variations, and particulate matter. These pose challenges to diffuser performance and efficiency.
Fine bubble diffusers maintain constant wastewater conditions to achieve optimal oxygen transfer and treatment. However, changes in wastewater characteristics, such as biological load, solids content, and pH levels, can affect diffuser efficiency and result in poor treatment quality.
For instance, high levels of suspended organic matter or solids in wastewater can foul and clog diffuser membranes. It can further reduce oxygen transfer and dissipation of energy consumption surface. Also, pH fluctuations can affect bubble formation and distribution, hindering the performance of fine pore diffusers.
Microbubble diffusers that are relatively incompatible with changing wastewater features can pose challenges for end-users. This vulnerability to seasonal variations in wastewater composition may hinder adoption and impede fine bubble oxygenation market growth.
