Modeling The Factors Affecting Sizing of Attached GrowthSystem of Wastewater Treatment Plant

Abstract

a computer programddeessiiggnneedd in Visual Basic Software 6.0 that used for designingattached growth system of wastewater treatment plants which are trickling filters,rotating biological contactor, and bio-towers. This program deals with the differentenvironmental factors that affecting the design of wastewater treatment steps. The verification between the results of the study with there results obtained fromhand calculations procedures showed agood agrrement The relationships between independent and dependent variables were determined bymultiple non - linear regression analysis using statistical program "Data Fit version8.0". The population was found to be the most significant variable affecting the design ofall wastewater units.
