Platforms

Considerations and Assumption

Parameters

Equations

The growth of the Biofilm can be modeled with modified continuous growth models. Traditional models of population growth make use of basic differential equations to measure the change in population over unit time. At the most fundamental level

Population Change Rate =	dN	= rN(1-N/K)
	dt

Where r is the positive rate of growth, K is the positive carrying capacity of the environment, and N is the population level.
