Modeling the factors affecting sizing of attached growth system of wastewater treatment plant

الملخص EN

a computer program designed in Visual Basic Software 6.0 that used for designing attached growth system of wastewater treatment plants which are trickling filters, rotating biological contactor, and bio-towers.

This program deals with the different environmental factors that affecting the design of wastewater treatment steps.

The verification between the results of the study with there results obtained from hand calculations procedures showed agood agrrement The relationships between independent and dependent variables were determined by multiple non - linear regression analysis using statistical program "Data Fit version 8.0".

The population was found to be the most significant variable affecting the design of all wastewater units.
