Solids capture shall be calculated as follows: 100 Xc Xe(Q f + Qp + Qw) % Capture = 1 Xc —Xe Xf x Qf Where: Xc=Sludge Cake Solids (percent by weight) Xe =Wastewater Suspended Solids (percent by weight) Xf= Feed Solids Concentration (percent by weight) Qf= Feed Sludge Flow (gallons per minute) (Total Processed/Duration) Qp = Dilute Polymer Flow (gallons per minute) Ow = Washwater Flow (gallons per minute) (Total Used/Duration) 3. Polymer Consumption: For each pound per ton above the specified maximum, $7,500 shall be deducted. E. Tests shall be completed within 120 days after the Owner receives notice of satisfaction of installation from the Equipment Manufacturer, in accordance with Paragraph 1.03(D) of this section. Unless extension of test period is granted by the Owner in writing, failure of Screw Press 46 76 22-15 Port Arthur Main WWTP Improvements Page 67 of 80 PTR15234 equipment to achieve satisfactory demonstration of performance within the 30 days specified herein shall be cause to declare the equipment defective.
