66 of 74  Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Conditions The tenderer shall prepare one calculation sheet for each scenario by using the below data.  Dewatered sludge, refers to the amount of solid in kg dewatered after anaerobic digester. For example  if total solids entered into the anaerobic digester is 1000 kg/day and total solids left anaerobic digester  after reduction of the volatile solids is 600 kg/day then this amount shall also enter into the  dewatering system. Therefore, amount of yearly dewatered sludge shall be 600 x 365 = 219,000 kg SS  dewatered/year, as to be entered in the below Table, item “b”.  The tenderer shall follow strictly all the conditions herein stated in his power calculation for sludge  load. Any other assumptions, figures and factors shall NOT be used unless clearly stated. The tenderer shall provide with the detailed electrical consumption table similar to the one below. For  all consumer items in the list, the tenderer shall provide calculation/supplier’s data and explanations.

Daily operation hours of anaerobic digesters  : all units, each with 24 hours/day  iv. Daily operation hours of mechanical thickener  (prior to centrifuges)  : required flow rate to be calculated based on  excess sludge produced at the wastewater  temperature given above and the solid content  of the excess sludge.
