To remove the excess nitrogen and phosphorus in swine wastewater, an electrodialysis technique was applied to an advanced treatment method. The laboratory-scale swine wastewater treatment system constructed for the present study consisted of an activated sludge process, as the main treatment unit, and electrodialysis, as an advanced treatment unit. This system was operated for 200 days and the ...

Background and Objective: Hospital waste water due to infectious organisms and other risk factors is important. In this study, the possibility of coliform bacteria removal from hospital waste water using ozone separately and combining with hydrogen peroxide (H2O2 + O3) as a pre-treatment was investigated. Material and Methods: This is an experimental study that in the second moiety of 1392 i...

Introduction: Effluents of Meat processing are one of the untreated wastewaters containing high volumes of polluted components even after the primary and secondary treatments. The high cost of using the advanced treatment methods of the wastewaters has led the industry owners to release them in the nature without effective removal of nitrogen and phosphorus. In this study, an economic advanced ...

RÉSUMÉ. In the contribution a (non-exhaustive) overview is given on the use of mathematical models in control systems of wastewater treatment plants. As a starting point for the overview, the four building blocks of any controlled process are used, 1) the process itself, 2) the actuators that allow manipulation of the process, 3) the control algorithm that calculates a proper action for disturb...
