Colloidal solids readily pass through the primary 47 treatment process and are treated in the secondary treatment process. Primary sedimentation 48 tanks reduce the wastewater velocity to less than 0.3 m/s (1.0 ft/sec) and allow these settleable 49 solids to separate from the waste stream. This process also removes a percentage of suspended
