A Performance Measurement Tool Leading Wastewater Treatment Plants toward Economic Efficiency and Sustainability

Risk Assessment Tool for the Design of Wastewater Treatment Plants

In 1990, the private company Aquafin was founded and assigned with the task of the design, construction, operation and financing of the necessary infrastructure for sewage treatment. One of the challenges Aquafin is facing now is to upgrade the patrimonium of old municipal wastewater treatment plants (WWTPs). These plants need to be retrofitted towards strict phosphorus and nitrogen removal con...

Performance Comparison of Predictive Controllers in Optimal and Stable Operation of Wastewater Treatment Plants

Any proper operation could be translated as a constrained optimization problem inside a WWTP, whose nonlinear behavior renders its control problems quite attractive for performance of multivariable optimization–based control technique algorithms, such as NMPC. The main advantage of this control technique lies in its ability to handle model nonlinearity as well as various types of constraints on...

Performance Indicator Analysis as a Basis for Process Optimization and Energy Efficiency in Municipal Wastewater Treatment Plants

Comparison of technical and economic efficiency of extended aeration and sequencing batch reactors processes in hospital wastewater treatment

Wastewater of hospitals can cause many risks to public health due to having a variety of pathogenic microorganisms, pharmaceutical substances, and other hazardous toxic substances. The aim of this study was to evaluate the chemical quality of effluents from wastewater treatment plant of Falsafi Hospital and Hakim Jorjani Hospital in Gorgan, Iran, and to compare them technically and economically...
