Systematic Biological Upgrade of a Urea Fertilizer Effluent Treatment Plant Using GPS

Markov modeling and reliability analysis of urea synthesis system of a fertilizer plant

This paper deals with the Markov modeling and reliability analysis of urea synthesis system of a fertilizer plant. This system was modeled using Markov birth–death process with the assumption that the failure and repair rates of each subsystem follow exponential distribution. The first-order Chapman–Kolmogorov differential equations are developed with the use of mnemonic rule and these equation...

Demonstration of effective and efficient tannery effluent treatment using an innovative integrated and compact biological and physical treatment plant

Post-treatment of secondary wastewater treatment plant effluent using a two-stage fluidized bed bioreactor system

The aim of this study was to investigate the performance of a two-stage fluidized bed reactor (FBR) system for the post-treatment of secondary wastewater treatment plant effluents (Shahrak Gharb, Tehran, Iran). The proposed treatment scheme was evaluated using pilot-scale reactors (106-L of capacity) filled with PVC as the fluidized bed (first stage) and gravel for the filtration purpose (secon...

Industrial Effluent Treatment by Novel Biological Reactor

1.1 Textile industry Textile industry is the largest industrial employer in the country, contributing to 6% GDP (Gross domestic product), 16% of export and about 18% of industrial production. The textile industry plays an important role in Indian economy. It contributes to 9% of excise collection, 30% of export revenue and 18% of employment in industrial sector. Since global trade in textile an...

Pharmaceuticals in Wastewater Treatment Plant Effluent Waters

Pharmaceuticals are being used at an increasing rate, and end up in wastewater through excretion and disposal. They also end up in the effluent water of wastewater treatment plants because they are not specifically designed for pharmaceutical removal. Several studies suggest diverse negative effects on aquatic life that are exposed to these trace amounts of pharmaceuticals in their habitats. Th...
