This paper presents a detailed thermodynamical exergy analysis of an optimized MSF distillation plant based on the latest published thermodynamics properties of water and seawater software of the Massachusetts Institute of Technology by using design and optimized plant operation data. Exergy flow rates are evaluated throughout the plant and the exergy flow diagram is prepared in both cases....

The aim of this research was to investigate the long-term hydraulic conductivity changes in sand-bed columns exposed to 2,4,6-trichlorophenol (TCP). Continuous flow laboratory studies were conducted using sand-bed columns (15 cm i.d.; 200 cm length) at 20+/-1 degrees C during 365 d. The influence of (i) initial loads of 2,4,6-TCP (15, 30, 45 and 60 mg kg(-1) of 2,4,6-TCP), and (ii) recirculatin...

Biofilm formation in recirculating water systems such as cooling towers lead to many undesired conditions in terms of public health concern, operational damage and economic loss. Accumulation of pathogenic bacteria (i.e. Legionella pneumophila), increased resistance to antimicrobial compounds, a significant energy loss by increasing heat transfer resistance, equipment damage through microbiolog...

Five crucian carp, Carassius auratus langsdorfiicarps had been reared in a closed water recirculating system. The system was equipped with the compact bioreactor using the plate gels capable of both nitrification and denitrification in a single unit. Ammonia and nitrite concentrations in the rearing water had been maintained below 0.05 mg-N/L, and nitrate concentration also controlled between 2...

INTRODUCTION The science of water disinfection is still a relatively new field for the tree fruit industry, as the widespread use of water disinfectants in this marketplace has only been occurring over the past couple of decades. In comparison, industrial water systems such as open recirculating cooling systems and evaporative condensers have been receiving chemical treatment for over five deca...
