Abstract

The paper presents the development of the conceptual, mathematical and system dynamics model for the food industry wastewater purification system which removes organic matter. The food industry often located in places where is difficult to install large systems for water purification while small sophisticated systems are expensive. Wastewater food industry is contaminated with organic matter, phosphorus and nitrogen compounds. This paper presents model of the small, cheap and effective cleaner water. The goal of the scientific investigation is developing such a model for purification wastewater and methodology design suitable to significant behavior patterns of contamination matter. Developed conceptual model is a computer variables model uses randomly chosen values from the theoretical probability distribution of the variable applied. For the validation of the model, considering that the distributions are asymmetrical non-Gaussian distributions, a non-parametric test was applied. Methodology proposed in the paper is mostly based on the simulation modeling.
