WEST: modelling biological wastewater treatment

The WEST++ Wastewater Treatment Plant Modelling and Simulation Environment

WEST++ is a modelling and simulation environment for any kind of process which can be described (in an Object– Oriented fashion) as a structured collection of Differential Algebraic Equations (DAE’s). Currently however, WEST++ is applied to Waste-Water Treatment Plant (WWTP) design and optimization. In particular, the IAWQ1 model [1] is the basis for a simple model of the dynamics of a basic WW...

Thermophilic Biological Wastewater Treatment

Thermophilic treatment is one of the advanced treatment technologies used for the purification of high-strength wastewaters. Thermophilic systems are conventionally used for sludge treatment, but their ability to reduce COD to a great extent with sludge generation one-tenth when compared to the other wastewater treatment technologies, have favored its application for wastewater purification. Mo...

Genomics of biological wastewater treatment

Cleaning up wastewater from domestic sewage and industrial processes is essential for safeguarding public health and the environment (for an overview of wastewater treatment processes see http://en.wikipedia.org/wiki/ Sewage_treatment). Biological wastewater treatment plants (WWTPs) employing sludge represent one of the most widely used biotechnological processes, with more than 120 billion lit...

Dairy Wastewater Treatment using Three-Stage Rotating Biological Contactor (NRBC)

Dairy wastewater is enriched in organic matter (about 45-72 g/l, COD) and also contains biodegradable carbohydrates. A three-stage system, NRBC was fabricated as a bench scale unit for lab experiments, to remove organic carbon from the whey. The fabricated NRBC had several advantages, such as quick start-up, high biomass concentration and was additionally able to handle high organic loading rat...
