BioWin32 is a simulator which allows you to analyze and design wastewater treatment plants. Numerous process units can be used to design a specific treatment plant configuration, including various influent elements for setting up wastewater inputs, storm flow inputs, or methanol addition streams\; equalization tanks\; continuous-flow bioreactors incorporating sophisticated means for simulating the performance of diffused aeration systems\; variable volume and batch bioreactors\; various-sequencing batch reactor modules\; aerobic digesters\; grit-removal tanks\; primary- and secondary-settling tanks\; generic dewatering units\; as well as mixers and splitters for directing flow between units in the configuration. BioWin32 incorporates an album function for viewing the simulation results. The album consists of a series of tabbed pages showing simulation results in tabular and graphical format. The program also enables you to use both Imperial and Metric units of measurement, generate reports, print your results, and utilize and customize the built-in templates.
