ASPSimulator.jl

ASPSimulator.jl is a lightweight Julia package designed for simulating Ordinary Differential Equations (ODEs) in the context of Activated Sludge Processes (ASP).

Quick Start Example

Below is a basic example demonstrating how to use the package:

using ASPSimulator, Dates, OrdinaryDiffEq, Plots

# Select the system model
system = :asm1

# Initialize the ODE core
core = ASPSimulator.ODECore(system, variable_inlet_concentration=false)

# Run the simulation for 14 days with specified aeration and waiting times
ts_asm1 = multi_step!(core, clock_control(t_aerating = 30.0, t_waiting = 60.0), Day(14))

# Plot the results
plot(ts_asm1[:, :nh4])

Supported Systems

Currently, the following ASP models are supported:

• ASM1 (Activated Sludge Model No. 1)
• Simplified ASM1
• Linear ASM1
