What is the consequence of running a paddle too slowly in a treatment process?

Running a paddle too slowly in a treatment process can lead to the formation of large flocs. This occurs because the slower mixing rate may not provide sufficient shear force to break down larger particles and enable them to collide more effectively with each other. In wastewater treatment, proper mixing is important as it encourages the growth of small flocs that can efficiently trap and settle out suspended solids and contaminants. When mixing is inadequate due to slow paddle speeds, the likelihood of forming larger, less efficient flocs increases. Large flocs may not settle properly, leading to operational challenges in the treatment system. Thus, maintaining appropriate mixing speeds is crucial for optimal floc size and overall treatment efficiency.
