Secondary Pump St<strong>at</strong>ion is significant<br />
grease and foam trapping structure<br />
• RAS and Primary Effluent mixed in wet<br />
well<br />
• Provides food for filament growth<br />
• Low level <strong>of</strong> aer<strong>at</strong>ion, bubble<br />
form<strong>at</strong>ion due <strong>to</strong> pump intake<br />
turbulence<br />
• Promotes filament growth, foam form<strong>at</strong>ion<br />
• Submerged withdraw from wet well<br />
keeps foam trapped<br />
• Seeds MP from foam in SPS <strong>to</strong> ABs even<br />
with foam control in ABs<br />
