In this article, we will delve into the world of BIOSCREEN, exploring its features, capabilities, and applications in the field of environmental science.

What is BIOSCREEN?

A Screening Model for Environmental Remediation

BIOSCREEN is a sophisticated screening model that simulates remediation through natural attenuation of dissolved hydrocarbons at petroleum fuel release sites. The model is designed to simulate biodegradation by both aerobic and anaerobic reactions, making it an invaluable tool for environmental scientists and researchers. By leveraging the power of BIOSCREEN, users can gain a deeper understanding of the complex processes involved in biodegradation, ultimately informing more effective remediation strategies.

Key Features of BIOSCREEN

Simulating Biodegradation Processes

BIOSCREEN is equipped with a range of features that enable it to simulate various biodegradation processes. These include:

Advection: The movement of dissolved hydrocarbons through the subsurface
Dispersion: The spreading of dissolved hydrocarbons due to molecular diffusion and mechanical mixing
Adsorption: The attachment of dissolved hydrocarbons to soil particles
Aerobic decay: The breakdown of dissolved hydrocarbons in the presence of oxygen
Anaerobic reactions: The breakdown of dissolved hydrocarbons in the absence of oxygen

How BIOSCREEN Works

A Step-by-Step Guide to Using BIOSCREEN

To use BIOSCREEN, users must first input a range of parameters, including:

Site characteristics: Information about the petroleum fuel release site, including the location, geology, and hydrology
Hydrocarbon properties: Information about the dissolved hydrocarbons, including their concentration, molecular weight, and solubility
Biodegradation parameters: Information about the biodegradation processes, including the rates of advection, dispersion, adsorption, aerobic decay, and anaerobic reactions

Once the input parameters have been entered, BIOSCREEN uses the Domenico analytical solute transport model to simulate the biodegradation processes. The model takes into account the complex interactions between the dissolved hydrocarbons, the subsurface environment, and the biodegradation processes.
