68 of 74  Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Power consumption, power production and ratio of power consumption for hydraulic, organic and  sludge loads to total consumption shall be entered in Schedule 11.8 Net Power Consumption sheet in  Volume 4 Schedule of Payments. Net Power Consumption [(Total power consumption for hydraulic,  organic and sludge load)- (Power production by CHPs)] shall be entered in Schedule 10.1 in Volume 4  Schedule of Payments. 3.4.2 Chemical Consumption Commitment 3.4.2.1 Chemical for Sludge Conditioning The Tenderer commits that the consumption of chemical is less or equal to the specified below:  The tenderer shall follow strictly all the conditions herein stated in his chemical calculation for sludge  conditioning. Any other assumptions, figures and factors shall NOT be used unless clearly stated. The Tenderer commits that chemical for sludge conditioning is less or equal to the one declared in  Volume 4, Schedule 11.4.  Conditions The tenderer shall prepare one calculation sheet for each scenario by using the below data.  i. The poly dosage rate for thickening shall be ≥ 3 kg dry poly / ton DS  ii. The poly dosage rate for dewatering shall be ≥ 4 kg dry poly / ton DS iii. Amount of excess sludge: to be calculated by the tenderer based on excess sludge produced at  the wastewater temperature given above, as kg/day and kg/year iv. Dewatered sludge, in Schedule 11.4 in Volume 4 refers to the amount of solid in kg  dewatered. For example if total solids entered into the dewatering system is 600 kg/day, then  the amount of yearly dewatered sludge shall be 600 x 365 = 219,000 kg SS dewatered/year, as  to be entered in the schedule, item “d”.  v. When the tenderer’s chemical consumption figure for excess sludge thickening (item “c” in  the schedule) divided by the tenderer’s value for amount of excess sludge (item “b” in the  schedule) i.e. c / b, the output figure in terms of kg dry polymer / kg SS shall be same as  given in the Guarantee for Performance section Table for “Guarantee Values for Wastewater  Treatment Plant” 3.4.2.2 Chemical for Phosphorus Removal  The Tenderer hereby commits that chemical for phosphorus removal is less or equal to the one  declared in Volume 4 Schedule 11.5.  Conditions The tenderer shall follow strictly all the conditions herein stated in his chemical calculation for  phosphorus removal. Any other assumptions, figures and factors shall NOT be used unless clearly  stated. 3_Vol3_d4.3_Section 3_Plant Description_GIR_rev08
