In 15 districts Punjab province Pakistan, chemical residues major groups including, neonicotinoids, organophosphates, carbamates pyrethroids were detected water samples...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

Water reuse has been practiced for over 5000 years; however, during the last 100 years efforts have been made in many regions of the world, for the production of high quality reused water, following strict quality guidelines. Technological advances are now permitting the production of reclaimed water suitable for direct potable pipe to pipe applications. In developed areas with intense water sc...

The world faces critical food security issues due to the combined pressures of population growth, depletion of finite resources and uncertainty in future climate. Of particular concern is the depletion of stocks in wild fisheries, and land-based aquaculture is one response to this problem. This research will look at opportunities to engineer highly efficient, integrated food production systems ...

egionnaires’ disease was first recognized in 1976 during an outbreak among attendees at an American Legion convention. The disease is a form of pneumonia caused by bacteria of the genus Legionella. Legionella thrives at warm temperatures (25–42oC [77–108oF]). It lives inside biofilm in aquatic environments, usually as an intracellular parasite of amoebae.1 This lifestyle protects it from disinf...

There are several concerns associated with the use of chlorine for potable water disinfection. These are the resistance of certain pathogens, the formation of toxic disinfection by-products and the adverse effects on aesthetic water quality. Owing to these concerns the water industry is continually reviewing alternative disinfection technologies. A methodology has been devised that will aid the...
